Got to finally drive around Union SC and check out the 97.5 frequency, and what a disaster....
Reminds me of driving around Chester SC and trying to listen to 104.7 (where both Charlotte and Columbia fight for the channel).
Driving around Union, 97.5 is not listenable in most spots, both stations are about equal in signal strength, sometimes WCOS is the stronger one (even strong enough for HD to lock in), but gotta go south of town for WCOS to work with no trouble. By the time you get up to Jonesville, Sports talk is strong enough to completely win the channel.
The null doesn't help at all...bad spot on the dial, perhaps another channel would be better, but the dial is pretty crowded by now...even the WBCU translator on 103.5 in Union doesn't really bother 103.3 Earth FM or 103.7 WSOC on either side, unless you're right next to their transmitter...
I think most of the city of Union falls on or close to the 60 dbu for WCOS so this is really bad for those that used to listen with no trouble there....
