Question for the “radio operators” here.
I'm looking for a radio for 2m and 70cm that can be flashed with the egzumer firmware in 2025. I have a Retevis RA79, but this device cannot be flashed. I've tried 5 different programming cables, but it just doesn't work.
What can you recommend? My price limit is €100.

Alternatively, I would also be interested in a device that comes with a spectrum analyzer, like the one in the egzumer firmware.
