WKSF doesn't really have to mention or advertise in Greenville as their 'sister stations' WSSL & WESC take care of the Upstate...
I see WESC as an alternative for both though since 100.5 has trouble in lots of NC area, and they lean towards classic country.
WSPA has 97.7 to try and compete in Asheville but yes they don't really advertise, the problem with Greenville vs Asheville markets
is that Greenville has alot more signals that reach Asheville, not really that many stations in Asheville to begin with.
101.9, 105.3 & 107.3 are owned by 3 different companies, with 105.3 trying to serve Charlotte,
but having a big following in the eastern part of the Upstate...
I've heard 101.9 mention Spartanburg a few times with some of their ads (but it's kinda rare).
When 105.3 IDs as "Gaffney/Charlotte" it makes it sound like's from the Upstate trying to cover Charlotte,
when it's really from the Charlotte market with 'some' Upstate coverage.
106.9 WMIT is trying to cover 4 or 5 markets but they're non commercial anyway....It'd be interesting if they ever went commercial
