Re: WBKA-AM and FM, Brockton, MA

I wonder about the bleed over because I when I travel back to Boston, from
Concord, on 93S, I lose it at about the Hookset tool booths. Since their tower
is in the Concord valley, right around the plains of Clinton St., I would
imagine that it doesn't get too far south. Although, I have not seen a WKXL
coverage map, so who knows.

<< 1450 is a graveyard (Class C, formerly Class IV) channel. The normally
 protected contour for Class C's is 1.0 mV/m (daytime; class C's get no
 protection at night). For all other classes, the normally protected contour
 is 0.5 mv/m day. (Class A stations are protected from co-channel
 interference to 0.1 mv/m day but are protected only to 0.5 mV/m from
 adjacent-channel interference.) That said (and it was a mouthful), WNBP and
 WKXL are about as closely spaced as any pair of co-channel Class C's that I
 know of. One reason is that the soil conductivity, especially around
 Concord, is about as poor as it gets.
 Whether there is prohibited overlap between WNBP and WKXL I can't say, but I
 know for sure that WNBP's former operation with 500W daytime on 1470 caused
 substantial prohibited overlap with the AM 1470 in Lewiston ME. When the FCC
 broke down the clear channels, the FCC itself cited WNBP's operation on 1470
 as a particularly unfortunate assignment, and used a possible move by WNBP
 to 820 as an example of the benefits radio listeners would reap from
 breaking down the clear channels. (Try telling that story now, especially to
 any AM listener in the northeast who has tuned across 1200 at night. What
 was once the clearest of clear channels is now virtually another graveyard
 channel.) >>
