Fm bug #309

Open va7kkw opened 3 years ago

va7kkw commented 3 years ago

First I would like to thank all for the hard work put forward to make the hobby great, second I understand fm is beta and wanted to share my findings.... Here goes..... Using a set of tk 8180 kenwood mobile radios, anytone 878 UV plus, Pi3b+ winters repeater hat and latest dashboard and mmdvm firmware...

Q3220e duplexer specs are LP -1.9dB Insertion Loss -75dB Isolation HP -2.0dB Insertion Loss -80dB Isolation

Swr is 1.3

RF output is 15 Watt

The issue is when fm=1 logs report received rf late entry causing rf drop

When fm=0 everthing works as it should

By rf drop I'm referring to dmr rf drop not fm rf drop

I have similar problems If I active FM, Fm run Ok but, DMR have a drop out for a moment when rf comes in. This cause a network stops running and all transmissions is dropped into the network.

I try to change ctcss threshold but no success at all.
