 ====== APRS with the NinoTNC ======
+**Note: This is currently a WIP **
 The NinoTNC can be used to send and receive [[https://en.wikipedia.org/wiki/Automatic_Packet_Reporting_System|APRS]] which will allow you to run an iGate, Digipeater or position beacon when used in conjunction with some additional software. As well as contributing to the APRS network, this might be useful to help  [[https://wiki.oarc.uk/packet_peer_finding|find local stations]] you can peer with to help build a national packet network.
-This document will cover installing and configuring the software to run as an Rx only iGate, with a periodic position beacon sent via RF. Two software packages are documented, you can chose one or the other. [[https://thelifeofkenneth.com/aprx/|Aprx]] is lightweight and easy to configure, and [[https://www.cantab.net/users/john.wiseman/Documents/BPQ32.html|BPQ32]] is more fully featured but harder to configure.

-The guides for both packages assume you're using Raspberry Pi OS or Debian, but may work for other Debian derivatives.

+===== NinoTNC / Radio Setup =====
+=== NinoTNC ====
+For 1200 Baud AFSK set the MODE switches to 0110.
+=== Radio ===
+The vast majority of APRS in the UK takes place on 144.800Mhz FM with narrow deviation. Configure your radio accordingly.

+==== Usage ====
+Aprx is relatively simple and once configured and started it should start to automatically forward packets to APRS-IS.
+To view the RF log:
+  tail -f /var/log/aprx/aprx-rf.log
+To view the generic log:
+  tail -f /var/log/aprx/aprx.log
+It might be useful to debug Aprx in the foreground. To do so, stop Aprx with
+  systemctl stop aprx
+Then run it in the foreground with the debug arguments:
+  aprx -f /etc/aprx.conf -v -dd -L
