you are going to disable the AFC functionality of your UHF Micor
receiver, you'll need to flip the diode polarity - all four, when going

Several of us are looking at putting up a low-power UHF MICOR Repeater at some
Solar Power sites. Standby receive power drain, of course, needs to be as low
as possible.

I still have more filters. Does anyone else want to put a Maxtrac on
902 MHz?

That's for sure about the MICOR UHF transmitter - follow the instructions,
including the special MICOR section notes on the Repeater-Builder web site.
Lately, every UHF MICOR Repeater transmitter that I've converted to the
440-450 ham band has had a big, nasty spur about 30 MHz above the

You should use a 403-430 split rx instead.

Umm-I got a question-are you converting the rx to narrowband?
The receiver does both wide and narrow band scan with programming
so it hears both band-widths/modes.
Otherwise, when they start putting people 7.5 Khz from your

Be sure to add a DC blocking capacitor to the input leads. The factory input

The radios that I have were from Canada, and was originally on 413 Mhz. So
chances are they will not hit the high side, but then also found that the xtal
was cut wrong.
