[App_rpt-users] Need help - Unexplained noise at startup or asterisk restart

I'd say you have the polarity of the COS and/or CTCSS backwards 
somewhere, and Asterisk is being told your radio has an open squelch 
which then blasts noise for the duration of the time-out timer.  Are you 
sure it behaves properly from then on?  Does opening the squelch reset 
the TOT and the process start all over again?  If not, maybe your 
COS/CTCSS detection isn't truly working.

Just a guess on my part...
