I have a micor base/repeater station and the second bpf the one attached to

in and I can't clean them up so I need a new one but don't know where to get
one can someone help me out???

What is the stamped model number of the filter you have, and what
frequency do you want it to pass?

This is a 225-400 MHz vertical antenna that cost the government $2933 when
new. Appears to be for the UHF aircraft band.

The slugs can be feed with MEK. However, you cannot get the high/high-high
split filter to tune to 146 MHz. The coils have to be changes as well as
the capacitors. I have converted some with little problem. After
conversion, the filter should be tuned with a sweep generator to get the
filter so
will a vhf one work on a uhf repeater?

I have one in a UHF 75-Watt MICOR repeater with the same problem. I've
unsoldered the cover that has to come off, and on this particular one, the
slugs are so frozen that the hex-head tool now won't fit anymore in the
slugs - they've become rounded out and just can't be gripped with anything.
So if
how about another way take the screws out the bottom punch out the epoxy run
a tap through to clean up the threads then make some new screws out of 10X32
1" long machine screw by cutting the heads off and putting a cut in the top
for a screw driver so that you can tune them up.

have you tried to remove the bottom plate and take the screws out from the
bottom with a pair of needle nose pliers. it worked on mine
and I found a set of set screws at mcmaster car 3/4" chrome plate steel
10x32 thread for 5.67. then just clean the threads up with a tap and put the

Turn the filter upside down with the screw heads in a tray of
acetone over night. Put the whole mess in a large glass
casserole dish with a lid to minimize the evaporation

I'm not familiar with Motorola, more so with GE. A local club was
given a UHF version MSF 5000 with 110 watt final. Do these make good

Also what is this Repeater worth on the open (e-bay) market???

To move it down the band you would have to add to the in sides. also it is
unity gain in the 1st place. It would be go to put on eBay or take it to a
ham-fest and make some money back on it to buy a good omni for your
repeater.

on a micor base/ repeater. can the ciculator be tuned on the bench with no
power to it or does the white plug need to be connect and the repeater
powered.

Rick,
I can't help you with any details on the antenna you have but I did once
work with 225-400 MHz ground to air
The simplest way to run two receivers from one feed is with a tee and
two 1/4 wave pieces of 75 ohm coax (or any odd multiple thereof) to each
receiver. Many of the Motorola and GE dual receiver mobiles use just that
scheme to do it. Of course you get 3 db loss this way but if you have a
preamp
Larry, Have you tried an easyout? It has worked in the past.
