Good questions, all. Let's tackle them:I have been able to get WFME 1560 from Nashua NH (near Boston) using an "audiophile" radio (a Denon AM tuner) which I suppose has a very good tuned RF stage. Not "good" reception; lots of noise including local electrical noise. So I suppose they are operating at their proposed 10 KW from their slant wire temporary facility as their last special temporary authority specified.
I would want to question what their future could be. Would they be permitted to stay at 10 KW on the slant wire "permanently"? Would they be required to downgrade to Class B to do so? Would they be required to find and move to another frequency (probably nearby, or slightly above 1600 KHz) to do so? If the FCC took back 1560 what would it be auctioned off as? The same thing WFME used to have, 50 KW DA2?
If they stayed on 1560 (at 10 KW) they could always apply for a new antenna location and power increase at a later date.
Historically WFME 1560 (as WQXR) was 10 KW ND day/night and sharing a frequency with the same California station (now KNZR) as they applied for Class A (then I-B) status. Their past and last directional patterns suggested they continued to put out roughly 10 KW in the direction of KNZR. Their last pattern suggested to me that they had trouble proofing their antenna at one point and had to pull in the pattern to the west but some augmentations still reached west at about 10 KW
No, it's unlikely that the slant wire can be used as a permanent licensed installation. The FCC gives stations much more leeway under STA than it does for licensed operation. Any licensed WFME operation will still need to protect KNZR's skywave as well as all the relevant co- and adjacent-channel groundwave signals. The FCC typically gives AM stations plenty of time on STA without requiring a return to a licensed facility, so it's easy to imagine the slant wire staying in use for a period of years unless someone else on 1560 complains about interference.
If WFME is ever licensed again, it would need to have at least 10 kW to retain class A status and protection of its skywave signal. Anything under 10 kW would downgrade it to class B status and only its groundwave signal would be protected from interference. It would *not* need to change channels for that - you can have a class B license on a channel where class A operation is allowed, and several former class A stations have downgraded to B (WOWO) or even D (KGA) status without changing frequency.
There is essentially no possibility of a frequency change. The only change that could be filed as a minor change would be moving up or down no more than 30 kHz. There are too many other signals packed in on nearby channels, including the daytimer on 1520 (moving to 1530) in Mineola, 1550s in Scranton and Hartford, 1570s in Bucks County PA and Long Island, 1580 on Long Island and WWRL on 1600. The spectrum is more clear for them on 1560 than anywhere else. There are no minor changes to the expanded band above 1600, so that's off the table. Also, moving to 1540, 1550, 1570 or 1580 would preclude any meaningful night signal, as those are clear channels reserved for the Bahamas, Canada or Mexico.
If Family were to surrender the 1560 license, it would not come back up for auction. AM facilities don't have a table of reserved allocations the way FM does. It would simply go away, and any other nearby station that could make a minor change could apply to make one - so, for instance, Hartford on 1550 could theoretically apply for 1560 if everything else around it would fit. If there were ever to be a new filing window for new AM signals or major changes to existing ones, the FCC wouldn't specify the parameters of the facility. It would be up to applicants to determine what would be feasible to propose.
