My Proposal for Chesapeake-Portsmouth Broadcasting (WBOB)

My proposal for WBOB in order to improve their FM coverage in the city of Jacksonville includes:

1) A "frequency swap" between Calvary Chapel of Twin Falls, ID (W300AS 107.9 FM/Orange Park, FL) and Chesapeake-Portsmouth Broadcasting (W262AG 100.3 FM/Orange Park, FL). This is necessary because W300AS is the only translator standing in the way of WBOB’s current translator W299BL (107.7 FM) and, furthermore, there are a number of full power stations on 107.7 FM, which includes WMGF (107.7 FM Mount Dora/Orlando, FL) and Class C2, 50kW WHFX (107.7 FM Darien/Brunswick, GA). With all of these stations in the way on 107.7FM, it makes the full coverage of the Jacksonville market impossible as it stands right now. In addition, there a number of full power stations and FM translators, both proposed translators and licensed translators, which prevent the upgrade of W262AG 100.3FM. Moreover, there is Class C, 100kW WRUM 100.3 FM in Orlando, FL, which can interfere with W262AG especially when the troposphere conditions are favorable from the south.

NOTE: After the trade, W262AG will rebroadcast Calvary Chapel programming from KAWZ in Twin Falls, ID, which is the same programming that they are currently broadcasting on W300AS.


2) Send an application to the FCC in order to move their current translator on 107.7 FM (W299BL/Jacksonville, FL) to 107.9 FM and upgrade the station from 99 watts @538 ft on top of the Wells Fargo Building in downtown Jacksonville and move it to one of the many radio towers off Hogan Road on the Southside of Jacksonville with a ERP of 250 watts @ 930 ft HAAT, which will lead to the deletion of the license of the other translator W300AS 107.9 FM in Orange Park. However, this will be done AFTER the frequency swap. The primary reason why 107.9 FM will be a better frequency for W299BL is because the nearest full-power station on 107.9 FM is WWRQ, a Class C2, 50 kW station in Valdosta, GA, which is nearly 100 miles away from Jacksonville, FL and it is far enough away so that the station will not cause prohibited interference with WWRQ.
While waiting for FCC approval and the construction of the new transmitter, the two stations, W299BL and W300AS, will rebroadcast programming that is on the main station, AM 600. When the construction of the translator on 107.9 FM is completed, WBOB will cover most of metro Jacksonville with a mono, not stereo, FM signal that is comparable to their competitor WOKV (106.5 FM), which will help them in the quest to topple WOKV in the ratings.

NOTE: The FM coverage will be similar to W279AG (WJNJ AM translator) IF it the current coverage pattern wasn’t directional.

Otharadioman, that's certainly an interesting proposal, but I'm not so sure how practical it is. Consulting engineers have to be hired, and all the FCC rules and regs have to be taken into consideration, etc. If Chesapeake-Portsmouth broadcasting was serious about an FM for WBOB-AM covering the entire Jax Metro, they should consider shopping around for at least a class A full coverage facility, like 106.5, which would afford some protection for the signal. Remember, even with 250 watts, unless you're located very close to the transmitter, a class D translator facility has very little, to no protection from full power co-channel, and adjacent channel stations. So while an FM translator might work great in a city the size of St. Augustine, making a translator work well in a city the size of Jacksonville would be a real technical challenge. ::)
