WBTS sharing with WUNI would certainly work, and there is enough room now, since WUNI now has only 2 channels - the 1080i primary channel and the 480i LATV. Coverage is good, and it may well be the best channel left for WBTS. WMFP first broadcast from the Lawrence area, soon moving that analog signal to a Boston office tower, but the COL remained as Lawrence. However that's too far north to be covered by WWDP, which has a very short tower, and limited coverage, requiring the COL change. Possibly WBTS could move to WWDP, but WMFP is probably most interested in keeping must-carry rights for the WMFP license.
