Hi everyone,

I am using a SharkRF M1KE (Callsign: K3JWD) and hitting a persistent issue with DMR+ and FreeDMR.

The Issue: I can connect to BrandMeister perfectly fine; I have full TX/RX audio. However, when I switch to DMR+ or FreeDMR profiles, I get absolute silence. The device status shows "Connected," but I hear no audio regardless of traffic.

What I have already tried (unsuccessfully):

FreeDMR: I understand this is "dial-on-demand." I have tried PTTing to activate a specific Talkgroup (like 91 or 2350). I see the transmission on the dashboard, but no audio comes back.

DMR+: I am aware of the Reflector workflow. I have linked a reflector and ensured I am listening on TG9, but it remains silent.

Volume: I have verified my volume settings are correct (since BrandMeister works).

Connectors: I am using the Homebrew/MMDVM connector set to MMDVM mode.

My Setup:

Device: SharkRF M1KE

Firmware Version: [Insert your Firmware Version here, e.g., v44]

Server: [Mention which specific server you are trying, e.g., FreeDMR UnitedKingdom or IPSC2-NewJersey]

Could you please advise if there are specific router ports or "advanced" M1KE jitter settings that need to be adjusted for these specific networks? Thanks ! K3JWD
