I live in Anderson county and find that trying to listen in on a "full" THP conversation is sometimes more hassle than its worth. That low band frequency is hard to pull in without a good antenna, and 90% of what they do is work wrecks and assist motorists on the interstates. I think N4YEK has the best advice of using 72.58 and 42.56 for your area. I cant wait until they switch over to a 700-800 system.
