Anytone and DMO mode. #77

Do you know why the Anytone 868 has so many problems with the DMO mode ...? When you use tg like 91 or 21461 in Spain you lose the audio and only recover it by playing the PTT or changing the channel. It seems as if I did not understand the simplex mode of transmission of the hotspot. Or do not like the treatment of Slot.

The same 868 has no problem in duplex repeater mode. Tested with MMDVM and MMDVM_HS 73

I've also seen that behavior with HD1 (but not often). It looks like to happen when we have some very short cuts in the network data stream (or corrupted data from network?), then the radio stop to decode. MMDVM_HS and MMDVM firmware are transparent to data that comes from MMDVMHost, then I don't believe this is a firmware problem. Just in case, try a 55 or 60 % of TX deviation, but more important check the firmware/settings of your radio, and be sure you are using the last release. I think you should inform this issue to Anytone.
