This is the noise I ear on my 3 GD77's with the scan is halting on a busy DMR channel.
(They all three have been bought at the begining, at the end of 2017)

The noise is the same when I manually switch from a frequency (no matter analog or DMR) to a different DMR busy frequency. For instance if I switch from VFO to DMR MR if the frequency is different, or from a channel to another one, no matter if the old channel is DMR or analog
I have several jumbospots and I meet the same bug. Every equipment is correctly tuned (BER about 0,2 - 0,3%)
This is not new with the last firmware version, for me it is the last really annoying bug with the openGD77 firmware compared to the stock one.
If this could be fixed it would be wonderful
