The problem I have ran into is when setting TX voice to 3.0 kHz I get a skipping of the tone. it goes away above 3.3 khc and below 2.9 kHz. the RX appears to be normal across the nodes I have connected to and save as expected.

I am using the Repeater- builder original RIM and where I has in previous version Dial of ASL installed for Raspberry pi the PL tone worked.out of TXmixB.

Is something different ?

The problem I have ran into is when setting TX voice to 3.0 kHz I get a
skipping of the tone. it goes away above 3.3 khc and below 2.9 kHz. the RX
appears to be normal across the nodes I have connected to and save as
expected.

You're saying you don't have the adjustment range from the software tuning
values? I've seen this before, and the solution was always to pad it
externally and get the adjustment in a more linear region of the set point.

It's why I prefer the RA-40 adapters, no need to set the deviation in software.

I am using the Repeater- builder original RIM and where I has in previous
version Dial of ASL installed for Raspberry pi the PL tone worked.out of
TXmixB.

Well perhaps Kevin can chime in, but I don't think there was much different in
his RIM.
