+## Version 1.7  --  October 2023 ##
+
+
+### New Documentation: ###
+
+Additional documentation location to slow down growth of main repository.  [https://github.com/wb2osz/direwolf-doc](https://github.com/wb2osz/direwolf-doc) .   These are more oriented toward achieving a goal and understanding, as opposed to the User Guide which describes the functionality.
+
+- ***APRS Digipeaters***
+
+- ***Internal Packet Routing***
+
+- ***Radio Interface Guide***
+
+- ***Successful IGate Operation***
+
+- ***Understanding APRS Packets***
+
+
+### New Features: ###
+
+
+
+- New ICHANNEL configuration option to map a KISS client application channel to APRS-IS. Packets from APRS-IS will be presented to client applications as the specified channel. Packets sent, by client applications, to that channel will go to APRS-IS rather than a radio channel.  Details in ***Internal-Packet-Routing.pdf***.
+
+- New variable speed option for gen_packets. For example,  "-v 5,0.1" would generate packets from 5% too slow to 5% too fast with increments of 0.1.  Some implementations might have imprecise timing.  Use this to test how well TNCs tolerate sloppy timing.
+
+- Improved Layer 2 Protocol [(IL2P)](https://en.wikipedia.org/wiki/FX.25_Forward_Error_Correction).    Compatible with Nino TNC for 1200 and 9600 bps.  Use "-I 1" on command line to enable transmit for first channel.  For more general case, add to config file (simplified version, see User Guide for more details):
+
+    > After:   "CHANNEL 1"   (or other channel)
+    >
+    > Add:     "IL2PTX 1"
+
+- Limited support for CM108/CM119 GPIO PTT on Windows.
+
+- Dire Wolf now advertises itself using DNS Service Discovery.  This allows suitable APRS / Packet Radio applications to find a network KISS TNC without knowing the IP address or TCP port.    Thanks to Hessu for providing this.  Currently available only for Linux and Mac OSX.  [Read all about it here.](https://github.com/hessu/aprs-specs/blob/master/TCP-KISS-DNS-SD.md)
+
+- The transmit calibration tone (-x) command line option now accepts a radio channel number and/or a single letter mode:  a = alternate tones, m = mark tone, s = space tone, p = PTT only no sound.
+
+- The BEACON configuration now recognizes the SOURCE= option.  This replaces the AX.25 source address rather than using the MYCALL value for the channel.  This is useful for sending more than 5 analog telemetry channels.  Use two, or more, source addresses with up to 5 analog channels each.
+
+- For more flexibility, the FX.25 transmit property can now be set individually by channel, rather than having a global setting for all channels.  The -X on the command line applies only to channel 0.  For other channels you need to add a new line to the configuration file.  You can specify a specific number of parity bytes (16, 32, 64) or 1 to choose automatically based on packet size.
+
+    > After:   "CHANNEL 1"   (or other channel)
+    >
+    > Add:     "FX25TX 1" (or 16 or 32 or 64)
+
+
+
+### Bugs Fixed: ###
+
+- The t/m packet filter incorrectly included bulletins.  It now allows only "messages" to specific stations.  Use of t/m is discouraged.  i/180 is the preferred filter for messages to users recently heard locally.
+
+- Packet filtering now skips over any third party header before classifying packet types.
+
+- Fixed build for Alpine Linux.
+
+### Notes: ###
+
+The Windows binary distribution now uses gcc (MinGW) version 11.3.0.
+The Windows version is built for both 32 and 64 bit operating systems.
+Use the 64 bit version if possible; it runs considerably faster.
+
+## Version 1.6  --  October 2020 ##
+
+### New Build Procedure: ###
+
+
+- Rather than trying to keep a bunch of different platform specific Makefiles in sync, "cmake" is now used for greater portability and easier maintenance.  This was contributed by Davide Gerhard.
+
+- README.md has a quick summary of the process.  More details in the ***User Guide***.
+
+
+### New Features: ###
+
+
+- "-X" option enables FX.25 transmission.  FX.25 reception is always enabled so you don't need to do anything special.  "What is FX.25?" you might ask.  It is forward error correction (FEC) added in a way that is completely compatible with an ordinary AX.25 frame.  See new document ***AX25\_plus\_FEC\_equals\_FX25.pdf*** for details.
+
+- Receive AIS location data from ships.  Enable by using "-B AIS" command line option or "MODEM AIS" in the configuration file.  AIS NMEA sentences are encapsulated in APRS user-defined data with a "{DA" prefix.  This uses 9600 bps so you need to use wide band audio, not what comes out of the speaker.  There is also a "-A" option to generate APRS Object Reports.
+
+- Receive Emergency Alert System (EAS) Specific Area Message Encoding (SAME).  Enable by using "-B EAS" command line option or "MODEM EAS" in the configuration file.  EAS SAME messages are encapsulated in APRS user-defined data with a "{DE" prefix.  This uses low speed AFSK so speaker output is fine.
+
+- "-t" option now accepts more values to accommodate inconsistent handling of text color control codes by different terminal emulators.  The default, 1, should work with most modern terminal types.  If the colors are not right, try "-t 9" to see the result of the different choices and pick the best one.  If none of them look right, file a bug report and specify: operating system version (e.g. Raspbian Buster), terminal emulator type and version (e.g.  LXTerminal 0.3.2).   Include a screen capture.
+
+
+- "-g" option to force G3RUH mode for lower speeds where a different modem type may be the default.
+
+- 2400 bps compatibility with MFJ-2400.  See ***2400-4800-PSK-for-APRS-Packet-Radio.pdf*** for details
+
+- "atest -h" will display the frame in hexadecimal for closer inspection.
+
+- Add support for Multi-GNSS NMEA sentences.
+
+
+
+### Bugs Fixed: ###
+
+- Proper counting of frames in transmit queue for AGW protocol 'Y' command.
+
+
+
+### New Documentation: ###
+
+- ***AX.25 + FEC = FX.25***
+
+- ***AIS Reception***
+
+- ***AX.25 Throughput: Why is 9600 bps Packet Radio only twice as fast as 1200?***
+
+- [***Ham Radio of Things (HRoT) - IoT over Ham Radio***](https://github.com/wb2osz/hrot)

+### Notes: ###
+
+The Windows binary distribution now uses gcc (MinGW) version 7.4.0.
+The Windows version is built for both 32 and 64 bit operating systems.
+Use the 64 bit version if possible; it runs considerably faster.
+
+
+
+## Version 1.5  --  September 2018 ##
+
+
+### New Features: ###
+
+- PTT using GPIO pin of CM108/CM119 (e.g. DMK URI, RB-USB RIM), Linux only.
+
+- More efficient error recovery for AX.25 connected mode.  Better generation and processing of REJ and SREJ to reduce unnecessary duplicate "**I**" frames.
+
+- New configuration option, "**V20**", for listing stations known to not understand AX.25 v2.2.  This will speed up connection by going right to SABM and not trying SABME first and failing.
+
+- New "**NOXID**" configuration file option to avoid sending XID command to listed station(s).  If other end is a partial v2.2 implementation, which recognizes SABME, but not XID, we would waste a lot of time resending XID many times before giving up.   This is less drastic than the "**V20**" option which doesn't even attempt to use v2.2 with listed station(s).
+
+- New application "**kissutil**" for troubleshooting a KISS TNC or interfacing to an application via files.
+
+- KISS "Set Hardware" command to report transmit queue length.
+
+- TCP KISS can now handle multiple concurrent applications.
+
+- Linux can use serial port for KISS in addition to a pseudo terminal.
+
+- decode_aprs utility can now accept KISS frames and AX.25 frames as series of two digit hexadecimal numbers.
+
+- Full Duplex operation.  (Put "FULLDUP ON" in channel section of configuration file.)
+
+- Time slots for beaconing.
+
+- Allow single log file with fixed name rather than starting a new one each day.
+
+
+
+### Bugs Fixed: ###
+
+- Possible crash when CDIGIPEAT did not include the optional alias.
+
+- PACLEN configuration item no longer restricts length of received frames.
+
+- Strange failures when trying to use multiple KISS client applications over TCP.  Only Linux was affected.  
+
+- Under certain conditions, outgoing connected mode data would get stuck in a queue and not be transmitted.  This could happen if client application sends a burst of data larger than the "window" size (MAXFRAME or EMAXFRAME option).
+
+
+- Little typographical / spelling errors in messages.
+
+
+### Documentation: ###
+
+
+- New document ***Bluetooth-KISS-TNC.pdf*** explaining how to use KISS over Bluetooth.
+
+- Updates describing cheap SDR frequency inaccuracy and how to compensate for it.
+
+### Notes: ###
+
+Windows binary distribution now uses gcc (MinGW) version 6.3.0.
+
+----------
+
+## Version 1.4  -- April 2017 ##
+
+
+### New Features: ###
+
+- AX.25 v2.2 connected mode.  See chapter 10 of User Guide for details.
+
+- New client side packet filter to select "messages" only to stations that have been heard nearby recently.  This is now the default if no IS to RF filter is specified.
+
+- New beacon type, IBEACON, for sending IGate statistics.
+
+- Expanded debug options so you can understand what is going on with packet filtering.
+
+- Added new document ***Successful-APRS-IGate-Operation.pdf*** with IGate background, configuration, and troubleshooting tips.
+- 2400 & 4800 bps PSK modems.  See ***2400-4800-PSK-for-APRS-Packet-Radio.pdf*** in the doc directory for discussion.
+
+- The top speed of 9600 bps has been increased to 38400.  You will need a sound card capable of 96k or 192k samples per second for the higher rates.  Radios must also have adequate bandwidth.  See ***Going-beyond-9600-baud.pdf*** in the doc directory for more details.
+
+- Better decoder performance for 9600 and higher especially for low audio sample rate to baud ratios.
+
+- Generate waypoint sentences for use by AvMap G5 / G6 or other mapping devices or applications.   Formats include
+ - $GPWPL	- NMEA generic with only location and name.
+ - $PGRMW	- Garmin, adds altitude, symbol, and comment to previously named waypoint.
+ - $PMGNWPL	- Magellan, more complete for stationary objects.
+ - $PKWDWPL	- Kenwood with APRS style symbol but missing comment.
+
+
+- DTMF tones can be sent by putting "DTMF" in the destination address,  similar to the way that Morse Code is sent.
+
+- Take advantage of new 'gpio' group and new /sys/class/gpio ownership in Raspbian Jessie.
+
+- Handle more complicated gpio naming for CubieBoard, etc.
+
+- More flexible dw-start.sh start up script for both GUI and CLI environments.
+
+
+ 
+### Bugs Fixed: ###
+
+- The transmitter (PTT control) was being turned off too soon when sending Morse Code.
+
+- The -qd (quiet decode) command line option now suppresses errors about improperly formed Telemetry packets.
+
+- Longer tocall.txt files can now be handled.  
+
+- Sometimes kissattach would have an issue with the Dire Wolf pseudo terminal.  This showed up most often on Raspbian but sometimes occurred with other versions of Linux.
+
+	*kissattach: Error setting line discipline: TIOCSETD: Device or resource busy
+	Are you sure you have enabled MKISS support in the kernel
+	or, if you made it a module, that the module is loaded?*
+	
+
+- Sometimes writes to a pseudo terminal would block causing the received
+frame processing thread to hang.   The first thing you will notice is that
+received frames are not being printed.  After a while this message will appear:
+
+  	*Received frame queue is out of control. Length=... Reader thread is probably 
+  	frozen.  This can be caused by using a pseudo terminal (direwolf -p) where 
+  	another application is not reading the frames from the other side.*
+
+- -p command line option caused segmentation fault with glibc >= 2.24.
+
+
+- The Windows version 1.3 would crash when starting to transmit on Windows XP. There have also been some other reports of erratic behavior on Windows. The crashing problem was fixed in in the 1.3.1 patch release.   Linux version was not affected.
+
+- IGate did not retain nul characters in the information part of a packet.  This should never happen with a valid APRS packet but there are a couple cases where it has.  If we encounter these malformed packets, pass them along as-is, rather than truncating.
+
+- Don't digipeat packets when the source is my call.
+
+
+
+----------
+
+## Version 1.3  -- May 2016 ##
+
+### New Features: ###
+
+- Support for Mac OS X. 
+
+- Many APRStt enhancements including: Morse code and speech responses to to APRStt tone sequences, new 5 digit callsign suffix abbreviation, 
+position ambiguity for latitude and longitude in object reports
+
+- APRS Telemetry Toolkit.
+ 
+- GPS Tracker beacons are now available for the Windows version.  Previously this was only in the Linux version.
+
+- SATgate mode for IGate.  Packets heard directly are delayed before being sent
+to the Internet Server.   This favors digipeated packets because the original
+arrives later and gets dropped if there are duplicates.
+
+- Added support for hamlib. This provides more flexible options for PTT control.
+
+- Implemented AGW network protocol 'M' message for sending UNPROTO information without digipeater path.
+
+
+- A list of all symbols available can be obtained with the -S
+command line option.
+
+- Command line option "-a n" to print audio device statistics each n seconds.  Previously this was always each 100 seconds on Linux and not available on Windows.
+
+### Bugs Fixed: ###
+
+
+
+- Fixed several cases where crashes were caused by unexpected packet contents:
+
+ - When receiving packet with unexpected form of GPS NMEA sentence.
+
+ - When receiving packet with comment of a few hundred characters.
+ 
+ - Address in path, from Internet server, more than 9 characters.
+
+- "INTERNAL ERROR: dlq_append NULL packet pointer." when using PASSALL.
+
+- In Mac OSX version:  Assertion failed: (adev[a].inbuf_size_in_bytes >= 100 &&   adev[a].inbuf_size_in_bytes <= 32768), function audio_get, file audio_portaudio.c, line 917.
+
+- Tracker beacons were not always updating the location properly.
+
+- AGW network protocol now works properly for big-endian processors
+such as PowerPC or MIPS.
+
+- Packet filtering treated telemetry metadata as messages rather than telemetry.
+
+----------
+
+## Version 1.2  -- June 2015 ##
+
+### New Features ###
+
+- Improved decoder performance.  
+Over 1000 error-free frames decoded from WA8LMF TNC Test CD.  
+See ***A-Better-APRS-Packet-Demodulator-Part-1-1200-baud.pdf*** for details.
+
+- Up to 3 soundcards and 6 radio channels can be handled at the same time.
+
+- New framework for applications which listen for Touch Tone commands
+and respond with voice.  A sample calculator application is included
+as a starting point for building more interesting applications.  
+For example, if it hears the DTMF sequence "2*3*4#" it will respond 
+with the spoken words "Twenty Four."  
+
+- Reduced latency for transfers to/from soundcards.
+
+- More accurate transmit PTT timing.
+
+- Packet filtering for digipeater and IGate.
+
+- New command line -q (quiet) option to suppress some types of output.
+
+- Attempted fixing of corrupted bits now works for 9600 baud.
+
+- Implemented AGW network protocol 'y' message so applications can
+throttle generation of packets when sending a large file.
+
+- When using serial port RTS/DTR to activate transmitter, the two
+control lines can now be driven with opposite polarity as required
+by some interfaces.
+
+- Data Carrier Detect (DCD) can be sent to an output line (just 
+like PTT) to activate a carrier detect light.
+
+- Linux "man" pages for on-line documentation.
+
+- AGWPORT and KISSPORT can be set to 0 to disable the interfaces.
+
+- APRStt gateway enhancements:  MGRS/USNG coordinates, new APRStt3
+format call, satellite grid squares.
+
+
+### Bugs fixed ###
+
+- Fixed "gen_packets" so it now handles user-specified messages correctly.
+
+- Under some circumstances PTT would be held on long after the transmit
+audio was finished.
+
+
+
+### Known problems ###
+
+- Sometimes writes to a pseudo terminal will block causing the received
+frame processing thread to hang.   The first thing you will notice is that
+received frames are not being printed.  After a while this message will appear:
+
+  Received frame queue is out of control. Length=... Reader thread is probably 
+  frozen.  This can be caused by using a pseudo terminal (direwolf -p) where 
+  another application is not reading the frames from the other side.
+
+-----------
+
+## Version 1.1  -- December 2014 ##
+
+### New Features ###
+
+- Logging of received packets and utility to convert log file
+into GPX format.
+
+- AGW network port formerly allowed only one connection at a 
+time.  It can now accept 3 client applications at the same time.  
+(Same has not yet been done for network KISS port.)
+
+- Frequency / offset / tone standard formats are now recognized.
+Non-standard attempts, in the comment, are often detected and
+a message suggests the correct format.
+
+- Telemetry is now recognized.  Messages are printed for
+usage that does not adhere to the published standard.
+
+- Tracker function transmits location from GPS position.
+New configuration file options: TBEACON and SMARTBEACONING.
+(For Linux only.   Warning - has not been well tested.)
+
+- Experimental packet regeneration feature for HF use.
+Will be documented later if proves to be useful...
+
+- Several enhancements for trying to fix incorrect CRC: 
+Additional types of attempts to fix a bad CRC.
+Optimized code to reduce execution time.
+Improved detection of duplicate packets from different fixup attempts.
+Set limit on number of packets in fix up later queue.
+
+- Beacon positions can be specified in either latitude / longitude
+or UTM coordinates.
+
+- It is still highly recommended, but no longer mandatory, that
+beaconing be enabled for digipeating to work.
+
+* Bugs fixed:
+
+- For Windows version, maximum serial port was COM9.
+It is now possible to use COM10 and higher.
+
+- Fixed issue with KISS protocol decoder state that showed up
+only with "binary" data in packets (e.g.  RMS Express).
+
+- An extra 00 byte was being appended to packets from AGW
+network protocol 'K' messages.
+
+- Invalid data from an AGW client application could cause an
+application crash.
+
+- OSS (audio interface for non-Linux versions of Unix) should 
+be better now.
+
+### Known problems ###
+
+- Sometimes kissattach fails to connect with "direwolf -p".
+The User Guide and Raspberry Pi APRS document have a couple work-arounds.
+
+-----------
+
+## Version 1.0a	-- May 2014 ##
+
+### Bug fixed ###
+
+- Beacons sent directly to IGate server had incorrect source address.
+
+-----------
+
+## Version 1.0 -- May 2014 ##
+
+### New Features ###
+
+- Received audio can be obtained with a UDP socket or stdin.
+This can be used to take audio from software defined radios
+such as rtl_fm or gqrx.
+
+- 9600 baud data rate.
+
+- New PBEACON and OBEACON configuration options. Previously
+it was necessary to handcraft beacons. 
+
+- Less CPU power required for 300 baud.  This is important
+if you want to run a bunch of decoders at the same time
+to tolerate off-frequency HF SSB signals.
+
+- Improved support for UTF-8 character set.
+
+- Improved troubleshooting display for APRStt macros.
+
+- In earlier versions, the DTMF decoder was always active because it 
+took a negligible amount of CPU time.  Unfortunately this sometimes 
+resulted in too many false positives from some other types of digital 
+transmissions heard on HF. Starting in version 1.0, the DTMF decoder 
+is enabled only when the APRStt gateway is configured.
+
+
+-----------
+
+## Version 0.9 --November 2013 ##
+
+### New Features ###
+
+- Selection of non-default audio device for Linux ALSA.
+
+- Simplified audio device set up for Raspberry Pi.
+
+- GPIO lines can be used for PTT on suitable Linux systems.
+
+- Improved 1200 baud decoder.
+
+- Multiple decoders per channel to tolerate HF SSB signals off frequency.
+
+- Command line option "-t 0" to disable text colors.
+
+- APRStt macros which allow short numeric only touch tone
+sequences to be processed as much longer predefined sequences.
+
+
+### Bugs Fixed ###
+
+- Now works on 64 bit target.
+
+### New Restriction for Windows version ###
+
+- Minimum processor is now Pentium 3 or equivalent or later.
+It's possible to run on something older but you will need
+to rebuild it from source.
+
+
+-----------
+
+## Version 0.8	-- August 2013 ##
+
+### New Features ###
+
+- Internet Gateway (IGate) including IPv6 support.
+
+- Compatibility with YAAC.
+
+- Preemptive digipeating option.
+
+- KISS TNC should now work with connected AX.25 protocols
+(e.g. AX25 for Linux), not just APRS.
+
+
+----------
+
+## Version 0.7	-- March 2013 ##
+
+### New Features: ###
+
+- Added APRStt gateway capability.  For details, see  ***APRStt-Implementation-Notes.pdf***
+
+
+-----------
+
+## Version 0.6 --	February 2013 ##
+
+### New Features ###
+
+- Improved performance of AFSK demodulator.
+Now decodes 965 frames from Track 2 of WA8LMF's TNC Test CD.
+
+- KISS protocol now available thru a TCP socket.
+Default port is 8001.
+Change it with KISSPORT option in configuration file.
+
+- Ability to salvage frames with bad FCS.

+Default of fixing 1 bit works well.  
+Fixing more bits not recommended because there is a high
+probability of occasional corrupted data getting thru.
+
+- Added AGW "monitor" format messages.
+Now compatible with APRS-TW for telemetry.
+
+
+### Known Problem ###
+
+- The Linux (but not Cygwin) version eventually hangs if nothing is
+reading from the KISS pseudo terminal.  Some operating system
+queue fills up, the application write blocks, and decoding stops.
+
+
+### Workaround ###
+
+- If another application is not using the serial KISS interface,
+run this in another window:
+
+	tail -f /tmp/kisstnc
+
+-----------
+
+## Version 0.5 -- March 2012 ##
+
+- More error checking and messages for invalid APRS data.
+

+# Dire Wolf #
+
+### Decoded Information from Radio Emissions for Windows Or Linux Fans ###
+
+In the early days of Amateur Packet Radio, it was necessary to use an expensive "Terminal Node Controller" (TNC) with specialized hardware.  Those days are gone.  You can now get better results at lower cost by connecting your radio to the "soundcard" interface of a computer and using software to decode the signals.
+
+Why waste $200 and settle for mediocre receive performance from a 1980's technology  TNC using an old modem chip?   Dire Wolf decodes over 1000 error-free frames from Track 2 of the [WA8LMF TNC Test CD](https://github.com/wb2osz/direwolf/tree/dev/doc/WA8LMF-TNC-Test-CD-Results.pdf), leaving all the hardware TNCs, and first generation "soundcard" modems, behind in the dust.
+
+![](tnc-test-cd-results.png)
+
+Dire Wolf includes [FX.25](https://en.wikipedia.org/wiki/FX.25_Forward_Error_Correction) which adds Forward Error Correction (FEC) in a way that is completely compatible with existing systems.  If both ends are capable of FX.25, your information will continue to get through under conditions where regular AX.25 is completely useless. This was originally developed for satellites and is now seeing widespread use on HF.
+
+![](fx25.png)
+
+Version 1.7 adds [IL2P](https://en.wikipedia.org/wiki/Improved_Layer_2_Protocol), a different method of FEC with less overhead but it is not compatible with AX.25.
+
+
+
+### Dire Wolf is a modern software replacement for the old 1980's style TNC built with special hardware. ###
+
+Without any additional software, it can perform as:
+
+ - APRS GPS Tracker
+ - Digipeater
+ - Internet Gateway (IGate)
+- [APRStt](http://www.aprs.org/aprstt.html) gateway
+
+
+It can also be used as a virtual TNC for other applications such as [APRSIS32](http://aprsisce.wikidot.com/), [Xastir](http://xastir.org/index.php/Main_Page), [APRS-TW](http://aprstw.blandranch.net/), [YAAC](http://www.ka2ddo.org/ka2ddo/YAAC.html), [PinPoint APRS](http://www.pinpointaprs.com/), [UI-View32](http://www.ui-view.net/),[UISS](http://users.belgacom.net/hamradio/uiss.htm), [Linux AX25](http://www.linux-ax25.org/wiki/Main_Page), [SARTrack](http://www.sartrack.co.nz/index.html), [Winlink Express (formerly known as RMS Express, formerly known as Winlink 2000 or WL2K)](http://www.winlink.org/RMSExpress), [BPQ32](http://www.cantab.net/users/john.wiseman/Documents/BPQ32.html), [Outpost PM](http://www.outpostpm.org/), [Ham Radio of Things](https://github.com/wb2osz/hrot), [Packet Compressed Sensing Imaging (PCSI)](https://maqifrnswa.github.io/PCSI/), and many others.
+ 
+ 
+## Features & Benefits ##
+
+![](direwolf-block-diagram.png)
+
+### Dire Wolf includes: ###
+
+
+
+- **Beaconing, Tracker, Telemetry Toolkit.**
+
+     Send periodic beacons to provide information to others.  For tracking the location is provided by a GPS receiver.
+     Build your own telemetry applications with the toolkit.
+
+
+- **APRStt Gateway.**
+
+     Very few hams have portable equipment for APRS but nearly everyone has a handheld radio that can send DTMF tones.  APRStt allows a user, equipped with only DTMF (commonly known as Touch Tone) generation capability, to enter information into the global APRS data network.  Responses can be sent by Morse Code or synthesized speech.
+
+- **Digipeaters for APRS and traditional Packet Radio.**
+
+    Extend the range of other stations by re-transmitting their signals. Unmatched flexibility for cross band repeating and filtering to limit what is retransmitted.
+
+- **Internet Gateway (IGate).**
+
+    IGate stations allow communication between disjoint radio networks by allowing some content to flow between them over the Internet.
+
+- **Ham Radio of Things (HRoT).**
+
+    There have been occasional mentions of merging Ham Radio with the Internet of Things but only ad hoc incompatible narrowly focused applications. Here is a proposal for a standardized more flexible method so different systems can communicate with each other.
+
+    [Ham Radio of Things - IoT over Ham Radio](https://github.com/wb2osz/hrot)
+
+- **AX.25 v2.2 Link Layer.**
+
+    Traditional connected mode packet radio where the TNC automatically retries transmissions and delivers data in the right order.
+
+- **KISS Interface (TCP/IP, serial port, Bluetooth) & AGW network Interface (TCP/IP).**
+
+    Dire Wolf can be used as a virtual TNC for applications such as [APRSIS32](http://aprsisce.wikidot.com/), [Xastir](http://xastir.org/index.php/Main_Page), [APRS-TW](http://aprstw.blandranch.net/), [YAAC](http://www.ka2ddo.org/ka2ddo/YAAC.html), [PinPoint APRS](http://www.pinpointaprs.com/), [UI-View32](http://www.ui-view.net/),[UISS](http://users.belgacom.net/hamradio/uiss.htm), [Linux AX25](http://www.linux-ax25.org/wiki/Main_Page), [SARTrack](http://www.sartrack.co.nz/index.html), [Winlink Express (formerly known as RMS Express, formerly known as Winlink 2000 or WL2K)](http://www.winlink.org/RMSExpress), [BPQ32](http://www.cantab.net/users/john.wiseman/Documents/BPQ32.html), [Outpost PM](http://www.outpostpm.org/), [Ham Radio of Things](https://github.com/wb2osz/hrot), [Packet Compressed Sensing Imaging (PCSI)](https://maqifrnswa.github.io/PCSI/), and many others.

+
+## Installation ##
+
+### Windows ###
+
+Go to the [**releases** page](https://github.com/wb2osz/direwolf/releases).   Download a zip file with "win" in its name, unzip it, and run direwolf.exe from a command window.
+
+You can also build it yourself from source.  For more details see the **User Guide** in the [**doc** directory](https://github.com/wb2osz/direwolf/tree/master/doc).
+
+
+
+
+### Linux - Using git clone (recommended) ###
+
+***Note that this has changed for version 1.6.  There are now a couple extra steps.***
+
+
+First you will need to install some software development packages using different commands depending on your flavor of Linux.
+In most cases, the first few  will already be there and the package installer will tell you that installation is not necessary.
+
+On Debian / Ubuntu / Raspbian / Raspberry Pi OS:
+
+    sudo apt-get install git
+    sudo apt-get install gcc
+    sudo apt-get install g++
+    sudo apt-get install make
+    sudo apt-get install cmake
+    sudo apt-get install libasound2-dev
+    sudo apt-get install libudev-dev
+    sudo apt-get install libavahi-client-dev
+
+Or on Red Hat / Fedora / CentOS:
+
+    sudo yum install git
+    sudo yum install gcc
+    sudo yum install gcc-c++
+    sudo yum install make
+    sudo yum install alsa-lib-devel
+    sudo yum install libudev-devel
+    sudo yum install avahi-devel
+
+CentOS 6 & 7 currently have cmake 2.8 but we need 3.1 or later.
+First you need to enable the EPEL repository.  Add a symlink if you don't already have the older version and want to type cmake rather than cmake3.
+
+    sudo yum install epel-release
+	sudo rpm -e cmake
+	sudo yum install cmake3
+	sudo ln -s /usr/bin/cmake3 /usr/bin/cmake
+
+Then on any flavor of Linux:
+
+	cd ~
+	git clone https://www.github.com/wb2osz/direwolf
+	cd direwolf
+    git checkout dev
+	mkdir build && cd build
+	cmake ..
+	make -j4
+	sudo make install
+	make install-conf
+
+This gives you the latest development version.  Leave out the "git checkout dev" to get the most recent stable release.
+
+For more details see the **User Guide** in the [**doc** directory](https://github.com/wb2osz/direwolf/tree/master/doc).  Special considerations for the Raspberry Pi are found in **Raspberry-Pi-APRS.pdf**
+
+
+### Linux - Using apt-get (Debian flavor operating systems) ###
+
+Results will vary depending on your hardware platform and operating system version because it depends on various volunteers who perform the packaging. Expect the version to lag significantly behind development.
+
+	sudo apt-get update
+	apt-cache showpkg direwolf
+	sudo apt-get install direwolf
+
+
+### Linux - Using yum (Red Hat flavor operating systems) ###
+
+Results will vary depending on your hardware platform and operating system version because it depends on various volunteers who perform the packaging.  Expect the version to lag significantly behind development.
+
+	sudo yum check-update
+	sudo yum list direwolf
+	sudo yum install direwolf
+
+
+### Macintosh OS X ###
+
+Read the **User Guide** in the [**doc** directory](https://github.com/wb2osz/direwolf/tree/master/doc).   It is more complicated than Linux.
+
+If you have problems,  post them to the [Dire Wolf packet TNC](https://groups.io/g/direwolf) discussion group.
+
+You can also install a pre-built version from Mac Ports.  Keeping this up to date depends on volunteers who perform the packaging. This version could lag behind development.
+
+	sudo port install direwolf

- * Name:        atest.c
- *
- * Purpose:     Test fixture for the AFSK demodulator.
- *
- * Inputs:	Takes audio from a .WAV file insted of the audio device.
- *
- * Description:	This can be used to test the AFSK demodulator under
- *		controlled and reproducable conditions for tweaking.
- *	
- *		For example
- *
- *		(1) Download WA8LMF's TNC Test CD image file from
- *			http://wa8lmf.net/TNCtest/index.htm
- *
- *		(2) Burn a physical CD.
- *
- *		(3) "Rip" the desired tracks with Windows Media Player.
- *			Select .WAV file format.
- *		
- *		"Track 2" is used for most tests because that is more
- *		realistic for most people using the speaker output.
- *
- *
- * 	Without ONE_CHAN defined:
- *
- *	  Notice that the number of packets decoded, as reported by
- *	  this test program, will be twice the number expected because
- *	  we are decoding the left and right audio channels separately.
- *
- *
- * 	With ONE_CHAN defined:
- *
- *	  Only process one channel.

+# direwolf versions thru 1.5 were available pre-built for 32 bit Windows targets.
+# Research and experimentation revealed that the SSE instructions made a big
+# difference in runtime speed but SSE2 and later were not significantly better
+# for this application.  I decided to build with only the SSE instructions making
+# the Pentium 3 the minimum requirement. SSE2 would require at least a Pentium 4
+# and offered no significant performance advantage.
+# These are ancient history - from the previous Century - but old computers, generally
+# considered useless for anything else, often end up in the ham shack.
+#
+# When cmake was first used for direwolf, the default target became 64 bit and the
+# SSE2, SSE3, SSE4.1, and SSE4.2 instructions were automatically enabled based on the
+# build machine capabilities.  This was fine until I tried running the application
+# on a computer much older than where it was built.  It did not have the SSE4 instructions
+# and the application died without a clue for the reason.
+# Just how much benefit do these new instructions provide for this application?
+#
+# These were all run on the same computer, but compiled in different ways.
+# Times to run atest with Track 1 of the TNC test CD:
+#
+#   direwolf 1.5 - 32 bit target - gcc 6.3.0
+#
+#	60.4 sec. Pentium 3 with SSE
+#
+#   direwolf 1.6 - 32 bit target - gcc 7.4.0
+#
+#	81.0 sec. with no SIMD instructions enabled.
+#	54.4 sec. with SSE
+#	52.0 sec. with SSE2
+#	52.4 sec. with SSE2, SSE3
+#	52.3 sec. with SSE2, SSE3, SSE4.1, SSE4.2
+#	49.9 sec. Fedora standard: -m32 -march=i686 -mtune=generic -msse2 -mfpmath=sse
+#	50.4 sec. sse not sse2:    -m32 -march=i686 -mtune=generic -msse -mfpmath=sse
+#
+#	That's what I found several years ago with a much older compiler.
+#	The original SSE helped a lot but SSE2 and later made little difference.
+#
+#   direwolf 1.6 - 64 bit target - gcc 7.4.0
+#
+#	34.8 sec. with no SIMD instructions enabled.
+#	34.8 sec. with SSE
+#	34.8 sec. with SSE2
+#	34.2 sec. with SSE2, SSE3
+#	33.5 sec. with SSE2, SSE3, SSE4.1, SSE4.2
+#	33.4 Fedora standard: -mtune=generic
+#
+# 	Why do we see such little variation?  64-bit target implies
+#	SSE, SSE2, SSE3 instructions are available.
+#
+# Building for a 64 bit target makes it run about 1.5x faster on the same hardware.

+%C%# Questions???  Join the discussion forum:  https://groups.io/g/direwolf
+%C%#
+%C%#
+%C%# This sample file does not have examples for all of the possibilities.
+%C%# Consult the User Guide for more details on configuration options
+%C%# and other documents for more details for different uses.
+%C%#
+%C%# These are the most likely settings you might change:
+%C%#
+%C%#	(1)   	MYCALL 	-  call sign and SSID for your station.
+%C%#
+%C%#			Look for lines starting with MYCALL and
+%C%#			change NOCALL to your own.
+%C%#
+%C%#	(2)	PBEACON	-  enable position beaconing.
+%C%#
+%C%#			Look for lines starting with PBEACON and
+%C%#			modify for your call, location, etc.
+%C%#
+%C%#	(3)	DIGIPEATER  -  configure digipeating rules.
+%C%#
+%C%#			Look for lines starting with DIGIPEATER.
+%C%#			Most people will probably use the given example.
+%C%#			Just remove the "#" from the start of the line
+%C%#			to enable it.
+%C%#
+%C%#	(4)	IGSERVER, IGLOGIN  - IGate server and login
+%C%#
+%C%#			Configure an IGate client to relay messages between
+%C%#			radio and internet servers.
+%C%#
+%C%#
+%C%# The default location is "direwolf.conf" in the current working directory.
+%L%# On Linux, the user's home directory will also be searched.
+%C%# An alternate configuration file location can be specified with the "-c" command line option.
+%C%#
+%C%# As you probably guessed by now, # indicates a comment line.
+%C%#
+%C%# Remove the # at the beginning of a line if you want to use a sample
+%C%# configuration that is currently commented out.
+%C%#
+%C%# Commands are a keyword followed by parameters.
+%C%#
+%C%# Command key words are case insensitive.  i.e. upper and lower case are equivalent.
+%C%#
+%C%# Command parameters are generally case sensitive.  i.e. upper and lower case are different.

+%W%# this with the available sound devices and capabilities:
+%W%#
+%W%#	Available audio input devices for receive (*=selected):
+%W%#	   *  0: Microphone (C-Media USB Headpho   (channel 2)

+%M%# Macintosh Operating System uses portaudio driver for audio
+%M%# input/output. Default device selection not available. User/OP
+%M%# must configure the sound input/output option.  Note that
+%M%# the device names can contain spaces.  In this case, the names
+%M%# must be enclosed by quotes.

+%C%# Multiple channels can have the same or different names.
+%C%#
+%C%# It can be up to 6 letters and digits with an optional ssid.
+%C%# The APRS specification requires that it be upper case.

+%C%# Example (don't use this unless you are me):  MYCALL WB2OSZ-5
+%C%#
+%C%
+%C%MYCALL N0CALL
+%C%
+%C%#
+%C%# Pick a suitable modem speed based on your situation.
+%C%#	1200 	Most common for VHF/UHF.  This is the default if not specified.
+%C%#	2400	QPSK compatible with MFJ-2400, and probably PK232-2400 & KPC-2400.
+%C%#	300	Low speed for HF SSB.  Default tones 1600 & 1800.
+%C%#	EAS	Emergency Alert System (EAS) Specific Area Message Encoding (SAME).
+%C%#	9600	G3RUH style - Can't use Microphone and Speaker connections.
+%C%#	AIS	International system for tracking ships on VHF.
+%C%#			Also uses 9600 bps so Speaker connection won't work.

+%C%# Push to Talk (PTT) can be confusing because there are so many different cases.
+%C%# Radio-Interface-Guide.pdf  in  https://github.com/wb2osz/direwolf-doc
+%C%# goes into detail about the various options.
+%C%
+%L%# If using a C-Media CM108/CM119 or similar USB Audio Adapter,
+%L%# you can use a GPIO pin for PTT control. This is very convenient
+%L%# because a single USB connection is used for both audio and PTT.
+%L%# Example:

+%W%# If using a C-Media CM108/CM119 or similar USB Audio Adapter,
+%W%# you can use a GPIO pin for PTT control. This is very convenient
+%W%# because a single USB connection is used for both audio and PTT.
+%W%# Example:
+%W%
+%W%#PTT CM108
+%W%%C%#
+%C%# The transmitter Push to Talk (PTT) control can be wired to a serial port
+%C%# with a suitable interface circuit.  DON'T connect it directly!
+%C%#
+%C%# For the PTT command, specify the device and either RTS or DTR.
+%C%# RTS or DTR may be preceded by "-" to invert the signal.
+%C%# Both can be used for interfaces that want them driven with opposite polarity.
+%C%#
+%L%# COM1 can be used instead of /dev/ttyS0, COM2 for /dev/ttyS1, and so on.
+%L%#
+%C%
+%C%#PTT COM1 RTS
+%C%#PTT COM1 RTS -DTR
+%L%#PTT /dev/ttyUSB0 RTS
+%L%#PTT /dev/ttyUSB0 RTS -DTR
+%C%
+%L%#
+%L%# On Linux, you can also use general purpose I/O pins if
+%L%# your system is configured for user access to them.
+%L%# This would apply mostly to microprocessor boards, not a regular PC.
+%L%# See separate Raspberry Pi document for more details.
+%L%# The number may be preceded by "-" to invert the signal.
+%L%#
+%L%
+%L%#PTT GPIO 25

-BACKGROUND:  This file addresses new additions proposals (OVERLAYS) 
-to the APRS symbol set after 1 October 2007.  The master symbol 
-document remains on the www.aprs.org/symbols/symbolsX.txt page.
+BACKGROUND:  Since October 2007, overlay characters (36/symbol) are
+allowed on all symbols.  This allows thousands of uniquely specified
+symbols instead of the original 188 (94 primary and 94 alternate).
+But the master symbol document,  http://aprs.org/symbols/symbolsX.txt, 
+only has one line per symbol.  So this added overlay list below gives 
+us thousands of new symbol codes.

+Description: Soundcard TNC for APRS
+ Dire Wolf is a software "soundcard" modem/TNC and APRS encoder/decoder. It can
+ be used stand-alone to receive APRS messages, as a digipeater, APRStt gateway,
+ or Internet Gateway (IGate). It can also be used as a virtual TNC for other
+ applications such as APRSIS32, UI-View32, Xastir, APRS-TW, YAAC, UISS, Linux
+ AX25, SARTrack, and many others.

- *
- * Inputs:	chan	- Audio channel.  0 for left, 1 for right.

- * Returns:	None 
- *
- * Descripion:	"9600 baud" packet is FSK for an FM voice transceiver.
- *		By the time it gets here, it's really a baseband signal.
- *		At one extreme, we could have a 4800 Hz square wave.
- *		A the other extreme, we could go a considerable number
- *		of bit times without any transitions.
- *
- *		The trick is to extract the digital data which has
- *		been distorted by going thru voice transceivers not
- *		intended to pass this sort of "audio" signal.
- *
- *		Data is "scrambled" to reduce the amount of DC bias.
- *		The data stream must be unscrambled at the receiving end.
- *
- *		We also have a digital phase locked loop (PLL)
- *		to recover the clock and pick out data bits at
- *		the proper rate.
- *
- *		For each recovered data bit, we call:
- *
- *			  hdlc_rec (channel, demodulated_bit);
- *
- *		to decode HDLC frames from the stream of bits.
- *
- * Future:	This could be generalized by passing in the name
- *		of the function to be called for each bit recovered
- *		from the demodulator.  For now, it's simply hard-coded.

-Dire Wolf is a software "soundcard" modem/TNC and APRS encoder/decoder.   It can 
-be used stand-alone to receive APRS messages, as a digipeater, APRStt gateway, 
-or Internet Gateway (IGate).    It can also be used as a virtual TNC for other 
-applications such as APRSIS32, UI-View32, Xastir, APRS-TW, YAAC, UISS, 
-Linux AX25, SARTrack, RMS Express, and many others.

-C# These are the most likely settings you might change:
-C#
-C#	(1)   	MYCALL 	-  call sign and SSID for your station.
-C#
-C#			Look for lines starting with MYCALL and 
-C#			change NOCALL to your own.
-C#
-C#	(2)	PBEACON	-  enable position beaconing.
-C#
-C#			Look for lines starting with PBEACON and 
-C#			modify for your call, location, etc.
-C#
-C#	(3)	DIGIPEATER  -  configure digipeating rules.
-C#
-C#			Look for lines starting with DIGIPEATER.
-C#			Most people will probably use the given example.
-C#			Just remove the "#" from the start of the line
-C#			to enable it.

-C#	(4)	IGSERVER, IGLOGIN  - IGate server and login
-C#
-C#			Configure an IGate client to relay messages between 
-C#			radio and internet servers.
-C#
-C#
-C# The default location is "direwolf.conf" in the current working directory.

-C# That is known as a server-side filter.  It is processed by the IGate server.
-C# You can also apply local filtering to limit what will be transmitted on the

-C# reports on channel 1. 
-C
-C#FILTER IG 0 t/m
-C#FILTER IG 1 t/wn

-C# Finally, we don't want to flood the radio channel.

- * Bug:  June 2015, version 1.2
- *
- * It has long been known that we will eventually block trying to write to a 
- * pseudo terminal if nothing is reading from the other end.  There is even 
- * a warning at start up time:
- *
- *	Virtual KISS TNC is available on /dev/pts/2
- *	WARNING - Dire Wolf will hang eventually if nothing is reading from it.
- *	Created symlink /tmp/kisstnc -> /dev/pts/2
- *
- * In earlier versions, where the audio input and demodulation was in the main 
- * thread, that would stop and it was pretty obvious something was wrong.
- * In version 1.2, the audio in / demodulating was moved to a device specific 
- * thread.  Packet objects are appended to this queue.
- *
- * The main thread should wake up and process them which includes printing and
- * forwarding to clients over multiple protocols and transport methods.
- * Just before the 1.2 release someone reported a memory leak which only showed
- * up after about 20 hours.  It happened to be on a Cubie Board 2, which shouldn't
- * make a difference unless there was some operating system difference.
- * (cubieez 2.0 is based on Debian wheezy, just like Raspian.)
- *
- * The debug output revealed:
- *
- *	It was using AX.25 for Linux (not APRS).
- *	The pseudo terminal KISS interface was being used.
- *	Transmitting was continuing fine.  (So something must be writing to the other end.)
- *	Frames were being received and appended to this queue.
- *	They were not coming out of the queue.
- *
- * My theory is that writing to the the pseudo terminal is blocking so the 
- * main thread is stopped.   It's not taking anything from this queue and we detect
- * it as a memory leak.  
- *
- * Add a new check here and complain if the queue is growing too large.
- * That will get us a step closer to the root cause.  
- * This has been documented in the User Guide and the CHANGES.txt file which is
- * a minimal version of Release Notes.
- * The proper fix will be somehow avoiding or detecting the pseudo terminal filling up
- * and blocking on a write.

+## Slide Show ##
+
+Brief summary of packet radio / APRS history and the capbilities of Dire Wolf.
+
+[Power Point presentation](https://github.com/wb2osz/direwolf-presentation)  -- Why not give a talk at a local club meeting?
+
+## Essential Reading ##
+ 
+- [**User Guide**](User-Guide.pdf)  [ [*download*](../../../raw/master/doc/User-Guide.pdf) ]
+
+	This is your primary source of information about installation, operation, and configuration.
+
+- [**Raspberry Pi APRS**](Raspberry-Pi-APRS.pdf)   [ [*download*](../../../raw/master/doc/Raspberry-Pi-APRS.pdf) ]
+
+	The Raspberry Pi has some special considerations that
+	make it different from other generic Linux systems.
+	Start here if using the Raspberry Pi, Beaglebone Black, cubieboard2, or similar single board computers.
+
+	
+## Application Notes ##
+
+These dive into more detail for specialized topics or typical usage scenarios.
+
+
+
+- [**AX.25 + FEC = FX.25**](AX25_plus_FEC_equals_FX25.pdf)  [ [*download*](../../../raw/dev/doc/AX25_plus_FEC_equals_FX25.pdf) ]
+
+	What can you do if your radio signal isn’t quite strong enough to get through reliably?  Move to higher ground?  Get a better antenna?  More power?  Use very narrow bandwidth and very slow data?
+
+    Sometimes those are not options.  Another way to improve communication reliability is to add redundant information so the message will still get through even if small parts are missing.  FX.25 adds forward error correction (FEC) which maintaining complete compatibility with older equipment.
+
+
+- [**AX.25 Throughput: Why is 9600 bps Packet Radio only twice as fast as 1200?**](Why-is-9600-only-twice-as-fast-as-1200.pdf)  [ [*download*](../../../raw/dev/doc/Why-is-9600-only-twice-as-fast-as-1200.pdf) ]
+
+	Simply switching to a higher data rate will probably result in great disappointment.  You might expect it to be 8 times faster but it can turn out to be only twice as fast.
+
+    In this document, we look at why a large increase in data bit rate can produce a much smaller increase in throughput.  We will explore techniques that can be used to make large improvements and drastically speed up large data transfer.
+
+
+
+
+- [**Successful APRS IGate Operation**](Successful-APRS-IGate-Operation.pdf)  [ [*download*](../../../raw/dev/doc/Successful-APRS-IGate-Operation.pdf) ]
+
+
+	Dire Wolf can serve as a gateway between the APRS radio network and APRS-IS servers on the Internet.
+
+    This explains how it all works, proper configuration, and troubleshooting.
+
+- [**Bluetooth KISS TNC**](Bluetooth-KISS-TNC.pdf)  [ [*download*](../../../raw/master/doc/Bluetooth-KISS-TNC.pdf) ]
+
+	Eliminate the cable between your TNC and application.  Use Bluetooth instead.  
+
+- [**APRStt Implementation Notes**](APRStt-Implementation-Notes.pdf)  [ [*download*](../../../raw/master/doc/APRStt-Implementation-Notes.pdf) ]
+
+	Very few hams have portable equipment for APRS but nearly everyone has a handheld radio that can send DTMF tones.  APRStt allows a user, equipped with only DTMF (commonly known as Touch Tone) generation capability, to enter information into the global APRS data network.
+	This document explains how the APRStt concept was implemented in the Dire Wolf application.  
+
+- [**APRStt Interface for SARTrack**](APRStt-interface-for-SARTrack.pdf) [ [*download*](../../../raw/master/doc/APRStt-interface-for-SARTrack.pdf) ]
+
+	This example illustrates how APRStt can be integrated with other applications such as SARTrack, APRSISCE/32, YAAC, or Xastir.  
+
+- [**APRStt Listening Example**](APRStt-Listening-Example.pdf)  [ [*download*](../../../raw/master/doc/APRStt-Listening-Example.pdf) ]
+
+
+	WB4APR described a useful application for the [QIKCOM-2 Satallite Transponder](http://www.tapr.org/pipermail/aprssig/2015-November/045035.html). 
+
+    Don’t have your own QIKCOM-2 Satellite Transponder?  No Problem.  You can do the same thing with an ordinary computer and the APRStt gateway built into Dire Wolf.   Here’s how.
+
+- [**Raspberry Pi APRS Tracker**](Raspberry-Pi-APRS-Tracker.pdf)   [ [*download*](../../../raw/master/doc/Raspberry-Pi-APRS-Tracker.pdf) ]
+
+	Build a tracking device which transmits position from a GPS receiver.
+
+- [**Raspberry Pi SDR IGate**](Raspberry-Pi-SDR-IGate.pdf)   [ [*download*](../../../raw/master/doc/Raspberry-Pi-SDR-IGate.pdf) ]
+
+	It's easy to build a receive-only APRS Internet Gateway (IGate) with only a Raspberry Pi and a software defined radio (RTL-SDR) dongle.  Here’s how.
+
+- [**APRS Telemetry Toolkit**](APRS-Telemetry-Toolkit.pdf)   [ [*download*](../../../raw/master/doc/APRS-Telemetry-Toolkit.pdf) ]
+
+	Describes scripts and methods to generate telemetry.
+	Includes a complete example of attaching an analog to 
+	digital converter to a Raspberry Pi and transmitting 
+	a measured voltage.
+
+
+
+- [**2400 & 4800 bps PSK for APRS / Packet Radio**](2400-4800-PSK-for-APRS-Packet-Radio.pdf)  [ [*download*](../../../raw/master/doc/2400-4800-PSK-for-APRS-Packet-Radio.pdf) ]
+
+
+	Double or quadruple your data rate by sending  multiple bits at the same time.
+
+- [**Going beyond 9600 baud**](Going-beyond-9600-baud.pdf) [ [*download*](../../../raw/master/doc/Going-beyond-9600-baud.pdf) ]
+
+
+	Why stop at 9600 baud?  Go faster if your soundcard and radio can handle it.
+
+- [**AIS Reception**](AIS-Reception.pdf) [ [*download*](../../../raw/dev/doc/AIS-Reception.pdf) ]
+
+
+	AIS is an international tracking system for ships.  Messages can contain position, speed, course, name, destination, status, vessel dimensions, and many other types of information.  Learn how to receive these signals with an ordindary ham transceiver and display the ship locations with APRS applications or [OpenCPN](https://opencpn.org).
+
+- **[EAS to APRS message converter](https://github.com/wb2osz/eas2aprs)**
+
+
+	The [U.S. National Weather Service](https://www.weather.gov/nwr/) (NWS) operates more than 1,000 VHF FM radio stations that continuously transmit weather information.  These stations also transmit special warnings about severe weather, disasters (natural & manmade), and public safety.
+
+    Alerts are sent in a digital form known as Emergency Alert System (EAS) Specific Area Message Encoding (SAME). [You can hear a sample here](https://en.wikipedia.org/wiki/Specific_Area_Message_Encoding).
+
+    It is possible to buy radios that decode these messages but what fun is that? We are ham radio operators so we want to build our own from stuff that we already have sitting around.
+
+
+## Miscellaneous ##
+
+- **[Ham Radio of Things (HRoT)](https://github.com/wb2osz/hrot)**
+
+
+	Now that billions of computers and mobile phones (which are handheld computers) are all connected by the Internet, the large growth is expected from the “Internet of Things.” What is a “thing?” It could be a temperature sensor, garage door opener, motion detector, flood water level, smoke alarm, antenna rotator, coffee maker, lights, home thermostat, …, just about anything you might want to monitor or control.
+
+    There have been other occasional mentions of merging Ham Radio with the Internet of Things but only ad hoc incompatible narrowly focused applications. Here is a proposal for a standardized more flexible method so different systems can communicate with each other.
+
+- [**A Better APRS Packet Demodulator, part 1, 1200 baud**](A-Better-APRS-Packet-Demodulator-Part-1-1200-baud.pdf) [ [*download*](../../../raw/master/doc/A-Better-APRS-Packet-Demodulator-Part-1-1200-baud.pdf) ]
+
+	Sometimes it's a little mystifying why an
+APRS / AX.25 Packet TNC will decode some signals
+and not others.  A weak signal,  buried in static,
+might be fine while a nice strong clean sounding
+signal is not decoded.  Here we will take a brief
+look at what could cause this perplexing situation
+and a couple things that can be done about it.	
+
+
+
+- [**A Better APRS Packet Demodulator, part 2, 9600 baud**](A-Better-APRS-Packet-Demodulator-Part-2-9600-baud.pdf) [ [*download*](../../../raw/master/doc/A-Better-APRS-Packet-Demodulator-Part-2-9600-baud.pdf) ]
+
+	In the first part of this series we discussed 1200 baud audio frequency shift keying (AFSK).  The mismatch 
+	between FM 	transmitter pre-emphasis and the 
+	receiver de-emphasis will 
+	cause the amplitudes of the two tones to be different.
+	This makes it more difficult to demodulate them accurately.
+	9600 baud operation is an entirely different animal.  ...
+
+- [**WA8LMF TNC Test CD Results a.k.a. Battle of the TNCs**](WA8LMF-TNC-Test-CD-Results.pdf)  [ [*download*](../../../raw/master/doc/WA8LMF-TNC-Test-CD-Results.pdf) ]
+
+	How can we compare how well the TNCs perform under real world conditions?
+	The de facto standard of measurement is the number of packets decoded from [WA8LMF’s TNC Test CD](http://wa8lmf.net/TNCtest/index.htm).
+	Many have published the number of packets they have been able to decode from this test. Here they are, all gathered in one place, for your reading pleasure.
+
+- [**A Closer Look at the WA8LMF TNC Test CD**](A-Closer-Look-at-the-WA8LMF-TNC-Test-CD.pdf)  [ [*download*](../../../raw/master/doc/A-Closer-Look-at-the-WA8LMF-TNC-Test-CD.pdf) ]
+
+    Here, we take a closer look at some of the frames on the TNC Test CD in hopes of gaining some insights into why some are easily decoded and others are more difficult.
+    There are a lot of ugly signals out there.   Many can be improved by decreasing the transmit volume.   Others are just plain weird and you have to wonder how they are being generated.
+
+
+## Additional Documentation for Dire Wolf Software TNC #
+
+
+When there was little documentation, it was all added to the source code repository [https://github.com/wb2osz/direwolf/tree/master/doc](https://github.com/wb2osz/direwolf/tree/master/doc) 
+
+The growing number of documentation files and revisions are making the source code repository very large which means long download times.  Additional documentation, not tied to a specific release, is now being added to  [https://github.com/wb2osz/direwolf-doc](https://github.com/wb2osz/direwolf-doc)
