+APRS lat/lon format is bizarre. See [[https://om1amj.sk/index.php/conversion-of-gps-coordinates-to-aprs-format|this]] to avoid having to work it out for yourself.

+==== Receive-only setup ====
+Do something like this to achieve a receive-only igate setup (e.g. if you are listening for telemetry beacons from remotely located kit, and you want to gate it to APRS-IS / aprs.fi)
+This will also put a BBS pin in the https://aprs.fi map for your own node, via the internet. Like [[https://aprs.fi/#!z=14&call=a%2FGB7RDG&timerange=3600&tail=0|this]].
+Put this new block outside the PORTS section of the config file, i.e. at the root level.
