Coverage - 99.5 vs. 102.5 which is "better"?

An interesting question is whether WCDJ is the reason that 102.5 uses
slightly less power than another station (WJMN?) that shares the same
multiplexed antenna on the FM-128 tower. One member of this list
periodicially posts to that effect but I am not sure that he is correct. As
best I can tell, however, the power difference (8.1 kW ERP for 102.5 vs--I
believe--8.3 kW for the other station) might be explained by WCRB's
forced move from the Channel 4 tower to FM-128, which might have
necessitated a reduction from the grandfathered equivalent power that 102.5
used from the Needham tower (equivalent to 50 kW at 500' HAAT) to the new
Class B equivalent power (equivalent to 50 kW at 150m HAAT; 150m is only

The slightly shorter distance from FM-128 to Truro might also explain the
power difference, but I've never been able to confirm that that IS
the reason. If the shorter spacing is the reason--or if short spacing to
102.3 in NH is the reason--I would think that Greater Media might now be
willing to pay for the installation of directional antennas at either or
both of these first-adjacent stations. Compared with the $100+ million that
GM reportedly paid for the 102.5 signal, the cost of a couple of DAs would
be chump change.
