WXRY is looking for a more clear channel (note the lower case). Effective coverage is limited on 99.3 by the presence of two co-channels on either side. 99.5 only has one co-channel WKXC Aiken/Augusta. The frequency change may not be implemented depending on what is the reality in the field. Once a filing window opens up, a major change is possible, so the several other, more clear channels, are possible.
KyleandMelissa, LPFM does not permit directional antennas, at this point. In addition, the Commission is proposing a 250watt upgade class for "rural" LPFM's. At this point, Columbia is not considered "rural." But that is just the proposed rules.
The I-20 stretch is a matter of antenna height. That stretch is below the WXRY antenna view because of the terrain. The Meridian Building also causes a major shadow to the SSE.
Powell, I believe 99.1 was granted to the Catholic Church in Barnwell. How soon it gets built is another matter.
