Group,
 Recent install of  listed build. 
Asterisk GIT Version adaec47 built by root @ odroidxu4 on a armv7l │ running Linux on 2018-03-07 14:53:41 UTC 

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 ?
