I finaly tracked down the .64 Beast after searching for 3+ years. My uncle broke down and drug out his IFR.
It was a combination of a switch mode battery charger in a boat about
300 feet from the antenna to give me a perfect mix 600kHz off the
transmit frequency, lower side band of course
I Think you got the Walts confused.
Walt Williams of Fort Worth Texas W5YUO is my freind and has built
more GREAT power supplies than he can remember is who Paul is talking
about. He had an old white full size van and even the police checked
him out for that weird thing on top of his van.

Try having your 222.6 repeater input frequency on a
nation-wide
The SSB/FM switch most often just changed the time
constant of the built in TR Relay (of this model and
type of amplifier).
I know, I'm not worried about that or the relay life, but I don't think
it was designed for continuous duty, nor probably to be all that clean.

Here is one that drove me nuts for almost a week when I was still at

- 260-foot freestanding tower
- 8-bay uhf antenna on top platform
- Connected to a MSF2000 transmitter on the city's 453.xxx paging
freq and a Zetron digital paging
I've mentioned this one before, but it bears repeating..
One afternoon, my father (K1FZY) gets a call from the chicago FCC.
Seems the local airport is having some interference, and they'd like
help tracking it down. Why they called dad is unknown.
So he calls me, and I go out to the tower,
Do you think some Motorola employee got a ticket sometime?
You know.. If that story is true, I'd call that one criminal.

I have heard about video distribution amplifiers doing similar things,

A complex in southwest suburban Chicago area had the local police searching

Well, your right. I think most of the time that's the case but we have made
such a stink about their poor antenna system they are charging a arm and a

Granted, but distant weak signals (in my experience) are the
exception on repeaters..not the rule. CTCSS on the input would have
kept the wireless mic(s) from getting through the repeater, until
someone keyed up the repeater with a valid signal. At that point, it

This is a factory equiped 150W circulator with the added heat sink
