[BC] Signal/Transmitter question... spur/harmonic or other issue?

[Mike McCarthy]

WUEZ is now on the WCIL-AM 1020 tower. The tower is located on the SW side
of town. I would not be surprised to see 1020 IM product mixing with the
FM's composite.  This would be a text book case for why a spectral proof
is required at installation.

HOWEVER, you might also be within the blanketing of the station as well
depending on the location in town. B-1 blanketing goes out about 1.5-2
miles depending on the power level. And WDBX's TX is only a couple miles
from WCIL-AM's tower

When I went to SIU, I had a dickens of a time reciving stuff at my house
because of that issue from WCIL-FM and WSIU-FM. Both of whom were less
than 2 miles apart and were 50KW ea. at the time.
