[App_rpt-users] Odd CTCSS behavior on RTCM

Fri Jun 13 03:25:32 UTC 2014

Ar you absolute sure your CTCSS line is doing what you expect? 

voter-plus.cry is for yet to be released hardware. It should work on the hardware you have… maybe… sorta. I’d stick with version 1.31 or so which is SVN Revision 1485 or there a bouts.
