# Documentation for Dire Wolf #
## Essential Reading ##
- [User Guide](User-Guide.pdf)
This is your primary source of information about installation, operation, and configuration.
- [Raspberry Pi APRS](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.
- [APRStt Implementation Notes](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.
Convert CHANGES.txt to .md format. Minor README updates.

- [APRStt Interface for SARTrack](APRStt-interface-for-SARTrack.pdf)
Move documentation to doc subdirectory. Add/update README.md files.
2015-08-09 00:51:05 +00:00
This example illustrates how APRStt can be integrated with other applications such as SARTrack, APRSISCE/32, YAAC, or Xastir.
- [Raspberry Pi SDR IGate](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)
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.
## Miscellaneous ##
- [A Better APRS Packet Demodulator, part 1, 1200 baud](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)
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.

- [WA8LMF TNC Test CD Results a.k.a. Battle of the TNCs](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.
