OpenGD77

AMAZING!!! Held the Orange and P1 and rocked the power supply power and got back to DFU and reloaded.

Thanks

I resolved this and have it working via an ESP32 for remote changing the channels.

I was upgrading firmwares on all my OpenGD77 radios the other night and inadvertantly loaded the load for the RT-3S to my RT-90. It will now not power on and I cannot renable DFU mode I'm sure do to the fact the buttons are different now since I loaded the wrong firmware. Anyone have any suggestions?

I found in the forums a pinout for the RJ45 Microphone and a schematic showing the resistor array setup. It's my understanding one Pin indicates row of pushed button and another pin the column. So I assume there is an ADC built into the radio. Can anyone confirm this and does anyone know if it's a 6...

Mic end of the cable doesn't remove. Radio side reseated to radio. Antenna is 9 +/- ft from radio and I'm driving it with a 30A Meanwell.

Issue has returned. Not sure what to try next

V5HW "appears" to have resolved it I'll follow up after further testing
