[arm-allstar] Heavy static and dropping from my HTs audio in FTM-400/ DMK URI Node

[David McGough]

Hi,

So, audio to AND from the node over RF is bad?

My first suspicion would be a bad ground connection (ground loop) between 
the radio and the RPi4. Or, perhaps RF (or other noise) getting into the 
audio connections.

How are you obtaining TX and RX audio from the FTM-400?? How are you 
powering the RPi4?

FTM-400s speak as well as the audio from the HT that I am using to 
connect to the node have very poor audio that I can not seem to adjust 
using the receive or transmit menus in HamVoip. The same system work fine 
through IC-9700 with a few adjustments in the menus. Has anyone else had 
the same experience, or have any feedback as to a possible remedy? I 
really would like to use the  Yeasu FTM-400 as my nodes radio.
