A long time ago, while working microwave, we had a series of charts that
showed most of the possible birdies in the 6 GHz and 11 GHz bands.  The
source carriers were some TV carriers plus or minus the baseband pilots or
the IF carrier of the MW systems (70 or 74 MHz; there were radio station
carriers and other listed sources of potential mixing.  So we had some good
charts that showed most of the possibilities  of how the MW freq.'s, sub and
super harmonics, TV carriers and color sub carriers as well as other things
all would eventually work to spoil the 290 kc to nearly 15 mc demodulated
basebands.

Therefore, I figured that someone had worked a bunch out over the years for
the standard broadcast band. 

Appreciate the replies, thanks guys and 
it's not too early to say Happy Thanksgiving
time to all of you.
