Hi everyone,
i am building a DMR Repeater with 2 CMD1550LS, and a Repeater builder STM32-dvm V3.

No Audio is repeated when a signal is received on RF. But network activity the audio will be transmitted OK.

Repeater TX is excellent when putting TG91 static and i can receive everything on my MD380.

But when i transmit on TG302233 with my MD380, Repeater is receiving signal and i see a line in the Live log and TX goes on and i see myself on the local Pi-Star dashboard or any other Pi-Star dashboard that is monitoring my TG302233

When listening on my XPR4580 (900) on TG302233 i do receive signal and the DMR ID but no audio is heard.
Transmitting with my XPR4580 on 900 Repeater i do received my audio on my MD380 thru the Repeater i am building.

On thing i dont have duplexer yet but TX is in a dummy load and RX with in dummy load

Could it be an issue with the STM32 board?

Running Pi-Star:4.1.4 / Dashboard: 20210224

Any input or suggestion for testing is welcome.

Silly question, but have you set the board up as per the instructions? Sounds like your levels are wrong. H

Well just found the issue
i was using a MD380 VHF that i never used and today i decided to use my Kydera CDr300UV and on my first try on the parrot and got the answer with my voice.
So i took the MD380 and when to 146.52 and surprise no audio on transmit but the DTMF are going thru, Try with a external Mic and working.
So probably the Mic cartridge is dead.
3 Day lost trying with this faulty radio.

Case is closed now.
Thanks for your inputs
