Curious, if you're using pistar have you messed with calibration, just to see what your particular radio likes for RX and TX? I have a GD77 and MD380 and they're both a little different, but plenty of overlap so no problems. But if you haven't, read this page and see what offset your radio likes for both receive and transmit and do it for both, maybe one of them is way off from the other.F6GVE wrote: ↑Sat Jan 18, 2020 11:08 pmThe only problem I have for a long time is this sort of desync/dropout/bug that I have when receiving DMR. It is pretty rare with one GD77 but relatively frequent with the second one (it is the same with calibration ON or OFF).
Also when scanning, if the scanner stops on a DMR RX, most of time there is a sort of hesitation (dont know how to describe) before I can clearly ear. I suspect that these two observations are linked.
I tried to adjust the "reference oscillator tuning" with no success. In fact I can almot supress the dropout (it lasts about 2 to 3 seconds every time it happens) if I set to be really off frequency. But in this case the DMR sensitivity is bad of course.
I could suspect some I Q calibration issue? But I had no way to be sure nor to do anything.
