S.O. still (after 20+ years of listening) on 155.580 repeater.
There is an input receiver in Vienna & Pinehurst, to help increase coverage.
Surprised (with all of their drug busts) they haven't gone 800/digital, with their neighbors north (Houston) and south (Crisp - analog 800) trunked.
IMHO, VHF P25 would be their best choice. Save the $$$ for a patch to the other counties...
