Need some help here with interference. Local came by and thought I was
interferring with his TV reception on Ch39.  Good trick since I was not even
at home during the period in question.  In the interest of good PR, decided
to give the OM a hand.  We exchanged phone numbers with instructions to him
to call me when he experienced it again.  Well, about 5pm he called with the
following observations. Modulation bars across ch 39; no interference on any
other channels. He uses external antenna, ch 39 is about 60 miles S, SE of
qth. His house is about 1/2 mile south of me. What is puzzling is that
sometimes the modulation stops but there is interference on his screen that
looks like a steady carrier. He has tried Radio Shack filters, etc.
What freq is ch 39? Harmonic of which ham freq, if any?
Could this be common mode via ac line?
Tnx for any suggestions
