You mentioned elsewhere that after the lightning strike in December (December?
A reminder of how warm that month was last year...I haven't seen any lightning
around here so far this spring.) that WLLH/Lawrence went back on at just 250 watts.
During the late winter, when the Lowell and Lawrence towers were in use, if
I drove around parts of Methuen, Lawrence itself and Andover, I got the 
"shortwave effect" that I would normally expect to get on route 110 at
the Methuen/Dracut line or on route 495 at the W. Andover/Tewksbury line.
I believe at least one radio in my home would slowly get distorted and then 
clear very slowly, something that occasionally happens with WBZ-AM at night
when a slight amount of skywave interferes with the groundwave signal.
