102.3 And 102.5

That great chin-stroker Scott Fybush earlier mused upon the possibility that the license-holder(?) of WCDJ-FM 102.3 in Truro (the Cape's HQ for anti-tocsins) might someday have to answer to the FCC for its lack of operation. If WCDJ's license were pulled, and the very CP on 102.3 withdrawn, would the owner of 102.5 COL Waltham, MA thereupon boost that frequency's power to the limit? Since the October windstorm, I don't know what wattage they're putting out now, but before then, WCRB was working with less power than WBOS had when they shared the route 128 antenna. There was only about a 700-watt difference, but at that altitude, it could have helped downtown listening a skosh, and added a boost to the contours outside of Metro Boston.

Would the 102.3 signal in Concord, NH prevent any power upgrade or are they far enough away?
 
I really don't know, but I doubt WCDJ had anything to do with WCRB's allowed signal coverage in the past. As far as I know, WCRB had been around a lot longer than WCDJ was even an idea. I would think it would be more likely that WCDJ would have to be limited for WCRB, not the other way around.

They're pretty far away. I was in Nashua, NH last week, about 10 miles north of the Massachusetts border, and tried to listen to WWHK 102.3. It came in very faintly; you could hear the classic rock very faintly over a ton of static.

I can't imagine that an upgrade of 102.5 would bring any complaints from WWHK.

A brief response to the above post. FM studies for increase of power or addition of new FM Channels are all done by computer study-If it fits on the study it gets granted. In AM the applicant has the option to take "real life" readings to surplant the computer models of signal propagation..In FM you take what you get. Overlaps over water and overlaps over non populated areas are permitted. WCDJ and WWHK were granted based on their distance from WCRB and in the case of WCDJ a need to run at a reduced power so as not to put a measurable signal onto land to the west.Coastal overlap where a distant signal-in AM-contour is measurable beyond a certain field strength on the coast is actually protected even if the incoming signal is far enough away so as not to be of interest to the average listener. In Commerical FM the FCC sets the channel assignments which appear on the FM Table of Allotments and it is from there that stations apply for licensing. New assignments are based upon either individual applicants requesting a new or change in the Table or from the FCC simply making additions or changes. In Non Commercial FM except in the border zones it is each man for himself as far as getting new stations engineered so that they don't cause interference to other applicants or existing stations. In AM it is simply each man for himself.

When the Truro allocation was added, WCRB was a full-power Class B operating from WBZ-TV's tower in Needham. When several years ago WCRB moved to the ex-Sconnix tower in Newton Upper Falls, they did so under the contour protection rule 73.215, as the new site is short spaced to Truro. They are operating several hundred watts below full Class B power as a result.

If WCRB's new owner wants to move it to the Prudential Center, there may be a problem because that site is too close to Truro to qualify under 73.215. I don't think it matters whether there is a station on the air in Truro or not; the allocation itself is protected.
