This is going to be a bigger problem than many stations may have
anticipated. A friend of mine has an all-channel antenna on a rotor and can
get 20 analog stations. He purchased a converter to see what he could get in
digital. He can only get four, and three of those pixilate quite badly.

I thought The Almighty and Everlasting Digital Signal (Praise Be To Its Bits
Eternally, Ignore That Pixellating Behind The Curtain ! ) was going to cure all
the supposed ills of that nasty old NTSC demon

Maybe your digital is less versatile than our here in Au ?
I live a long way from the tx site and experience little degredation with my
nice shiny new set top box and antenna .
Or maybe your analogue setup simply doesn't work well on the wrong frequencies
?

commission a study for repair let alone an actual fix ?
Digital either works or it don't , we all know that so why do some find it so

One thing to remember with the M10 is that it belongs to the same
family as the M120 and GM300.
Your fan(s) MAY be causing vibrations in the receive or transmit radio
rather than radiated RF noise.
There have been many problems with receive microphonics at high
receive volume levels and weird TX
Yup. Woefully inaccurate (too optimistic) for my location too, but
after zooming all the way in I am impressed with their terrain data. :-)

I had mixed results. It said I'd get stations that I can't and said I won't
get stations that I do.
Same thing for another location I checked.

I've made this same setup many times.
I usually mount a fan blowing directly on the TX radio.
I then put a 50 ohm 10 watt power resistor in the line to the fan with a 1000
uf capacitor 25 volt capacitor to ground on the fan side of the resistor.
This setup will take out most or all of the dc

Before I can suggest anything I need some more information. Is this a
Motorola repeater, in a cabinet with a motorola power supply? Are you using
a motorola RIC, basically - what is the configuration of the repeater?
I ask this because it has been well documented in the

I find it horribly inaccurate since it doesn’t take into account receiving

How much RF does it take to get a clear NTSC picture? Usable?
I know the local cable tower tried to get at least a -20 dBm signal (!!!) on
analog TV inputs.
Most DTV converter units with published spec's need between -82 dBm and -86
dBm at the antenna jack on the back of the unit to capture a
