WBCB is a different kettle of fish. If they are doing well as Pell guys says then it is because the station lives in the shadows of Philadelphia and Trenton; the 50kw FM and 50kw AM stations probably don't spend a lot of time talking about Levittown (even though those their signals are very strong there). BCB then fills the niche by superserving Levittown. Wilkes-Barre/Scranton stations serve the two cities and all the towns in between: you hear Avoca mentioned, Moosic, Old Forge, Pittston, Kingston, etc etc. What could WARM provide that is not already being provided? Answer that question and you've got a format. The bigger problem is trying to get people to listen to AM. If using FM translators helps build audience and exposes listeners to the AM frequency(s) then it all adds up to more listening, which is what radio is all about. Unfortunately AM-only stations in smaller markets like W-B/Scr do not bring in lots of listeners. The exception was WILK which had respectable numbers, but even with 910/980/1300 they still felt the need to add 103.1. From the time WILK was purchased by Keymarket in 1987 is has more or less been some sort of news/talk (consistency is their history of the past 26 year). In this same span WARM was left to crumble to nothing. Resurrecting WARM means not just investing in a format and personnel but tons of money to fix the physical plant.
Look at WTOP in DC with loads of heritage and commitment to its format when it was on AM; where is it now? 103.5/103.9/107.7 (the AM is now WFED) Why? Because the 50kw 1500khz with a good physical plant was not enough to compete in today's FM (and now increasingly internet) world. In NY Why is WFAN on FM, WEPN on FM? Boston WEEI on FM. To be able to compete.
Kevin, as you stated (and I have alluded to above) Gem using FM translators has lead to some people finding 730/1460. Where would Gem be today if you only had 730/1460 and no FM translators?
