The Working Configuration
I’ve gotten APRS working with my current gear. I’m running my UV-K5 running egzumer 0.22.0 and VOX enabled. I set the radio volume pretty high, about 75%, and connected the BTech APRS cable and a USB-C 3.5mm audio adapter to my Pixel 6 Pro for an audio connection. The volume on the phone was set to nearly 100% volume. I ran APRSDroid in AFSK mode on the phone.
I watched for my position to show up on the map on https://aprs.fi/.
The Stuff That Didn’t Work
With nunu firmware, I needed to key it manually, but it worked. VOX didn’t work in the nunu 0.20.5, so I switch back to egzumer for working VOX.
Next Steps
I’ll next try to find an old phone to run the APRSDroid and try to use the Explorer QRZ-1, so I can dedicate some hardware to this project.
