Every good points. I hear the people running WFTE are not going a good job. A FM would be better. There is one thing there is WARM FM.
I can't comment on WFTE as I haven't listened to it except for 5 minutes of syndicated program they had on. As far as WARM-FM: This came about when Susquehanna (which owned both 590 WARM and 103.3 WSBA-FM York) decided to change WSBA-FM to 'Warm' 103, hence WARM-FM. Cumulus now owns both 590 WARM and 103.3 WARM-FM, but they dropped the moniker 'Warm' 103 and instead the station is now called 'Wink' 103 (to match Cumulus owned Wink 104 WNNK) even though the call sign is still WARM-FM. When 590 WARM was briefly on 97.1 Mountaintop (now WBHT) it was WYRM but you only heard those call letters mentioned at the top of the hour.
These things do happen though: 930am WBEN Buffalo (Owned by Entercom who own KRZ) is simulcast on 107.7fm WLKK Wethersfield Twp but you never hear any mention of WLKK except at the top of the hour. They gave permission to Greater Media to put the WBEN-FM call sign on 95.7fm Philadelphia (95.7 Ben-FM).
750am WSB Atlanta is simulcast 95.5fm WSBB, but the station is known on air as 750am 95.5fm 'WSB.' The real WSB-FM is also in Altanta but is known only as B98.5. Same with San Francisco: 740 KCBS is simulcast on 106.9 KFRC-FM but the station is known as 740am 106.9fm KCBS, but the real KCBS-FM is in Los Angeles called '93.1 Jack FM'
Maybe the option would be to downgrade 590 (if this is possible) to allow a much much less expensive way of getting the transmission facility fixed (less towers, less copper radials, etc), but also simulcast on 1340/1400/1440/94.3/100.9 and any other translators you can get a hold of to have the maximum coverage area as possible. This scenario though looks strangely familiar: Gem 104 is doing just this: Two AMs (1460 WGMF / 730 WZMF) and a bunch of FM translators, and it has worked. Gem does reasonably well in the book.
Looking back it is a damn shame that WARM was left to rot. We could have had the Mighty 590 and 92.9FM, WARM: A killer AM and FM combo that would have been untouchable with the best FM and best AM signals in the market. Back then though you had the problem of WARM on 97.1 and Magic on 92.9, and it was this scenario that killed WARM as 97.1 was not supposed to compete with 92.9.
