The hard part was not the wiring. It was teaching two radio languages to translate, and the first read on the problem was wrong.https://n0de73.com/blog/reverse-engineering-a-dmr-handheld/Wed, 07 Oct 2026 08:00:00 -0700https://n0de73.com/blog/reverse-engineering-a-dmr-handheld/Programming a Cotre CO06D with no real software for it meant talking straight to the radio’s debug port and mapping its memory by hand. The best bug turned out to be a reset default hiding as a hardware fault.https://n0de73.com/blog/analog-to-fusion-and-dmr/Wed, 07 Oct 2026 01:00:00 -0700https://n0de73.com/blog/analog-to-fusion-and-dmr/Bridging an analog AllStar node to digital voice, Fusion first and then DMR, on a single Pi with no hardware vocoder. The hard part was the AMBE encoder, and the first diagnosis of it was wrong.
