[TriLUG] Television & RF interference -- yes computer related -- I think

[James Jones]

According to the preacher and the producer, NO NEW EQUIPMENT, NO CHANGES.

In the "younger" days of Ham Radio, there was a better chance of
possible interference, because most Ham gear was made by the
operators. Now that MOST ham gear is commercially made, I suspect
interference would be minimal. If it is caused by a Ham Operator, I
would suspect some one new to the neighborhood near the church.

I plan to put filters on the power line going to the MAC as a first
step, then the video distribution amplifier.

Note, the church building is mainly a metal building with brick front.
