APRS-GB: An APRS-based guestbook

I always liked the Automated Packet Reporting System and immediately after I've got my HAM operator license, I started reading some of the specifications. Besides having plans, that probably every APRS newbie has, like creating my own iGate or radio-only weather station, I decided to create a APRS-based guestbook or maybe chat if you wish.

The principle is very simple: send direct APRS message with OK1ZXS-15 as addressee and the text of it (max 67 character as per APRS specification) will be published here. If necessary, ACK will be send back to you. The status of APRS-GB software can be checked on aprs.fi - when the last packet is older than about an hour, then the service is down. Otherwise it will ping the APRS-IS with uptime every plus/minus 3600 seconds.

Consider this to be just a toy, proof-of-concept and beta-quality service: It may or may not work. All testing was done via TCPIP* without real APRS message sending capable transceiver. Every feedback is welcome, just send me an e-mail to martin@ok1zxs.cz (mail address not clickable on purpose).

Changelog:

  • 2020-05-25 First version online, there is no local deduplication yet, so if your TRX keeps sending (as when you are in RX-only iGate area), the aprs-gb keeps adding it!
