FM with Pi-Star

Post by G0FHM »

Hi Guys,

I run a DMR/YSF/FM repeater with Pi Star and a Winters (BI7JTA) board.

The FM functionality seems to be rather troublesome!

Every now and again it either "takes off" and holds itself open with lots of audible hash, or when it is opened it will just keep kerchunking till it times out.

Looking at the live logs, the board is reporting a valid signal with CTCSS (even on a DL), and constant scrolling of MMDVM DAC levels have overflowed.

I suspect it's the MMDVM firmware that is causing the problem. There have only been 2 releases of FM compatible firmware (the last being December 2020)

Any thoughts would be appreciated!

Thanks, Jay G0FHM
