mumble on RX, has a tendency to produce full volume audio spikes that can wreck the ears...
Mumble's internal coding engines can also squash down CW AUDIO TONEs
since they are using the same frequency pitch all the time, (? mumble thinks it is noise and needs to be rid of ? ) etc...
however, by using INTERRUPT CW MODE, rEvErSe iMaGe mOrSe cOdE via a sine sweep continuous carrier from 100 hz to 1000 hz & back,
the full volume RX audio spikes(from opus audio encoding/decoding packet issues)
and the down-VOLUMiNG of steady state sine wave tones are virtually eliminated
the riCW interrupt cw mode method utilizes on TX & RX, a regate sidechain DUCKing VST plugin
