[R-390] Mistake in my last image post

[ANTHONY CASORSO]

A list member was kind enough to point out a mistake in my post that I 
prefer to call a typo :).

I said:

"If you don't have a spectrum analyzer, you can buy or build a simple BCB 
filter. If the filter does not reduce the signal at the second harmonic then 
it is not the broadcaster."

I should have said it IS the broadcaster. Too many negatives in that 
sentence. Hopefully I didn't send anybody into the weeds with that.
