I *think* that's what Louis is suggesting: that WPAX take over WHGH's old facilities on 840.
The problem is, the 840 facility is a daytimer -- a station operating on that frequency is not allowed to operate at night. (not even the minimal dozen or two watts allowed to most Class D stations)
WPAX could apply to move from 1240 to 840, increasing its daytime power. The FCC would probably grant it. However, WPAX would then lose any authority to operate at night. There are a couple of ways they could address that:
- FM translator. I see two translators authorized to operate in the 92-108 commercial band (101.9 & 103.7); WPAX might buy one of these & use it to relay their new 840 AM signal. The translator may remain on the air after the AM signs off at sunset, as long as the AM has operated in the last 24 hours. The translators are a bit wimpy (103.7 is 35 watts, 101.9 is weaker) so the night coverage won't be very good unless an upgrade is possible.
- Relicense AM 1240, so they could hold *both* frequencies. 1240 has poorer coverage but can operate at night, which 840 can't. WPAX could apply to move their existing station to 840. 1240 would then be deleted -- but WPAX would immediately apply to reauthorize 1240, as a completely new station, with the same technical facilities it already has. (they can't apply for a completely new station on 840, because the FCC no longer accepts applications for new Class D stations.) WPAX would have to compete for 1240 with other potential applicants. Someone else might get their old frequency, in which case WPAX would lose all authority to operate at night. Also, I'm not familiar with the duopoly situation in Thomasville; it may not be permissible for the same firm to own both AM stations.
- Modify the 1240 license to specify split operation, using 840 during the day & 1240 at night. There *is* one such split-frequency operation in the U.S.; a station near Detroit uses 690 during the day & 680 at night. I don't see anything in FCC regulations specifically prohibiting such a thing. On the other hand, there's a significant difference between the Detroit operation and a 840/1240 Thomasville split: the Detroit station uses two adjacent frequencies. In Thomasville, an 840/1240 split would tie up two frequencies for one station. My gut feeling is the FCC wouldn't approve it.
In any of these cases, WPAX would have to wait for a filing window. This could take years. It would then take more years for the FCC to act on the applications filed.
I need to note.. that there is essentially zero chance WPAX could be licensed as a fulltime station on 840 -- zero chance they could operate 24 hours on the old WHGH frequency. There's a Class A station on 840 in Louisville, Kentucky. This station is entitled to protection of its nighttime *skywave* coverage area -- and Thomasville is located well within this area.
