FM APRS not working on UV390 (Beta 2023 08 09)

Post by lu2efi » Wed Aug 09, 2023 9:30 pm

Hi! I've downloaded today version (I'm fascinated with the work of the OpenGD77 team, congratulations!), and tried the new FM APRS functionality. No APRS settings loaded on CPS and when trying to transmit on VFO 144.390, only a 1 second tone is transmitted (same audio on the speaker and in another radio receiving on that frequency).
Is there any step I'm missing?

Thanks in advance

SK1??

There are currently some bugs in the CPS for the APRS

SSID can't be changed, its always transmitting SSID 6 and keeps resetting in the CPS to 7

I will fix this soon

Tried with both combinations:
- PTT + SK2 (as mentioned viewtopic.php?f=5&t=3120: just a 1 second tone transmission
- PTT + SK1: no tone, just mic audio

Did you set the location ?

Yes, and updated it a couple of times with the GPS (GPS module was off when testing)

Saved your current codeplug

Make an APRS config e.g. APRS1 and assign it to the channel you are using and then try again

I can see a path through the code is you have invalid APRS data that it will then not transmit it

Tried that, same behaviour: I've created an APRS1 config, with default settings and assigned to a new channel (analog, 144.390). When transmitting on this channel (only PTT) I get just a clean carrier with expected mic audio. If I press PTT+SK2, an (almost) 1 second tone sounds and gets transmitted. If I keep pressed PTT+SK2, speaker plays that tone just once but in the transmission the tone is regulary repeated. With previous codeplug, symptoms were exactly the same.

PTT+SK2 sends a 1750 Hz tone for repeater access. This has always been there.

New APRS uses PTT+SK1

Pressing PTT+SK1 is exactly the same that pressing the PTT alone, just mic audio: tried both VFO and the channel with APRS config associated to it.

What is the firmware code in the firmware info screen?

Zip and post your codeplug
