SOTA2APRS is an experimental service that posts the SOTA activations (spots and alerts) and some summit locations to APRS-IS. Web based clients showing the positions on maps include aprs-map.info, APRS.fi or agwtracker.
SOTA2APRS reports
- every activator "spotted" on SOTAwatch to APRS-IS with his current frequency as
(or
on some clients).
- example:
ON6ZQ 007.032MHz SOTA activation ON/ON-001
- SOTA spots that contain the words "test" or "ignore" in their comment are not reported to APRS-IS.
Activators who would prefer NOT to be listed on APRS when their activations are spotted on SOTAwatch are welcome to let me know -> mailto:info [snail] on6zq [period] be, and I'll make sure their callsign is added to the black-list. - example:
- every announced activation ("alert") with the date and time of planned activation as
(or
on some clients)
- example:
ON/ON-001 SOTA activ. planned on YYYYMMDD HHMMz
- example:
"
- In addition to spots and alerts, SOTA2APRS also monitors in real time the stations that use the
symbol (/[), and determines if they are in the vicinity of a SOTA summit and moving.

- example:
ON/ON-001 Summits On The Air - www.sota.org.uk
This means that
- any moving stations that use the
symbol will be shown with the SOTA summits nearby.
- in particular, activators carrying an APRS tracker (or an APRS enabled transceiver, or a mobile phone running an application like APRSdroid) will be shown on the map with the location of the summit they are going to as
.

SOTA2APRS is purely experimental, and is meant
- to make the SOTA related activities known to a larger public
- while helping
- chasers to follow the activators progression
- activators to be chased and assisted if necessary
It may be adapted or stopped without notice depending on the feed-back I receive.
Note: SOTA2APRS must not be confused with the gateway service APRS2SOTA provided by Stewart G0LGS, allowing users of the APRS network to post spots on the SOTAwatch system.
Here is a diagram describing the flows between SOTawatch, APRS2SOTA, SOTA2APRS and RBNhole.
The SARTrack client is a very advanced Amateur Radio APRS program, perfect to follow the SOTA activators progression.
