I own a openspot 2 and 3. The 2 has started producing distorted audio on transmit and it is also low. I have tried reset, autocal (corrects the frequency by 400 but then I can't access the OS 2 at all until I set it back to zero), but still have the problem. I have tried two transceivers and the shark does it with both. This doesn't happen when a signal comes in through the Brandmeister system from elsewhere (no distortion), only when I transmit directly to the OS2. My sharkRF 3 works great with these 2 transceivers. I'm at a loss as to what to try next. Thanks for any help.

Please run AutoCal, or manually change the RX offset on the Modem page in +-100Hz steps to find out the offset with the lowest BER. You can test it by using the OS2's built-in local echo service on DMR ID 9999.

Thanks, I will try again.

Hello Norbert and thanks for your help. I ran autocal several times and it kept showing "0" correction. I finally went 100 hz at a time and arrived at +400. It seems to work better but still testing. Todd, WA7U
