Is this roughly how #APRS messaging is supposed to work in 2020? Extra Features subscription package coming to iOS app stores near you in a month or two! Messaging, APRS-IS beaconing, DSP "sound card" modem.

Here's a little web app to search the current #APRS device identifier / tocalls database - it always loads the fresh one from the source (some caching applied in the CDN, but still): aprsorg.github.io/aprs-deviceid-…

aprs.fi had some hickups in APRS-IS data intake today. Software bug triggered by erratic input. Sorry about that.

If you're using the aprs.fi API, please note that the plain HTTP API URLs will stop working on 2026-05-01, and all calls need to be done using https:// URLs. The new HTTPS URLs were already introduced back n 2017-03-09. Using https will keep your API keys safe.

Controller replacement done, back to normal.

Aprs.fi is having a short maintenance break due to hardware upgrades. 4T SSDs and new disk controllers.

I have made a proposal fix PR for these issues: github.com/begass/LoraAPR…

Looking for folks maintaining iot4pi LoRa gateways in Austria, there are two bugs affecting the rest of the world: github.com/begass/LoraAPR… groups.io/g/APRS/topic/a…

I ported the APRS parser used by aprs.fi to the Go language during the weekend, with the help of Claude Code. It’s got all the same unit tests so it might even mostly work! 20x faster than the Perl version. github.com/hessu/go-aprs-… #aprs #hamradio

aprs.fi iPhone/iPad app 2.7.4 is out! • User guide updated: how to change email address (yes, it’s finally in there). • Translation updates • Quicker refresh of shown data on map in certain situations • Rebuilt for iOS 26 • Fixed a rare bug #hamradio

iPhone app v2.7.3 is out! • TNC waterfall view shows Mark/Space frequency marker lines for tuning aid on HF SSB • Improved refresh timing on map and favourite station list • Show 5 decimals in decimal degrees • Show a message when zoomed out too much Etc… #hamradio #aprs

@n4ejm Now it’s released. Direct USB to Icom IC-7610 works for receive but that radio firmware doesn’t do VOX for USB audio and USB serial PTT control is impossible on iOS. The TS-590S/SG should work!

@n4ejm Note that the 300 baud modem is still cooking, it’s not released in any shape or form yet.

Friday night fun: Compiled the DSP modem with settings for 300 baud HF packet, plugged it in the HF rig, and it actually receives some packets, and my transmissions are being heard in Germany and Austria! Splendid! Note VOX off.

aprs.fi iOS app v2.7.2 now available, with a 300 baud HF AX.25 modem! It uses 1600 / 1800 Hz Mark/Space frequencies, like Dire Wolf, so the 30m APRS dial frequency is 10147.60 kHz USB. This is an initial version - tuning aids are missing. #aprs #hamradio

Basic LinHT GUI (WIP), by @OE3ANC ^SP5WWP

@n4ejm No, I used the digirig VOX PTT cable digirig.net/product/vox-pt… and digirig.net/product/icom-d… to ACC connector of the radio. Quick hardware VOX. USB should be possible too but requires using VOX on the radio, I’ll try that later.

@aprsfi Did you use a USB B to USB C cable?

Another update! iOS app v2.7.1 embeds the new User Guide (also at ios-guide.aprs.fi) and enables a new complete translation to Slovak! Thanks go to the contributor of the translation, it’s quite a project!

New user guide! ios-guide.aprs.fi

@KD9RDO I can’t commit to a schedule, sorry.

@aprsfi Great updates !!! Timeline on Object placement?

aprs.fi for iPhone/iPad v 2.7.0 is out! • It's now possible to manually configure TCP KISS TNC like we used to in the 1990's. • New real-time scope in the DSP modem, with Metal/GPU acceleration so that the CPU usage is not affected!
