They must be running lower power at night, as WOFX covers them at times in parts of Tewksbury, only 4 to 6 miles as the crow flies from their TX site. Even as close as 2 to 3 miles east of the TX within the Lowell city limits WOFX can be faintly heard underneath if there's a pause in programming. I don't know what the issue is that may be causing this. I do know the main TX is the Harris MW-5 that was bought new for when they made the jump from a 1KW daytimer to 5KW fulltime DA-2 back in October 1980. The aux TX is the 1KW that was moved over from their former site in Dracut.
And yesterday (Wed). between 10:05 & 11:00AM they ran a couple of radio infomercials, caught the end of one with the disclaimer for the preceding was a paid program for some medical company, then a disclaimer for one shilling some kind of brain disease cure or such. They have 30 minute medical infomercials every Saturday & Sunday at 1:05PM. Only ethnic show on WCAP currently is "Hellenic Happenings.com", a Greek music program Sundays at 12:05PM, hosted by Nick Diamontopoulos (a/k/a Nick Diamond), who worked at WLLH in the 1970's.
