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 somewhat flat over the frequencies that you want to use the radio. 
The filter in a mobile usually does not have epoxy filling the coil form.

RE: [Repeater-Builder] help I need

[[EMAIL PROTECTED]]

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 anyone has another set besides the one David needs, I could sure use
one, too. It will finish up another UHF Repeater - everything else works
fine.

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.

Re: [Repeater-Builder] help I need

[David]

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
new ones in reassemble and tune it up. I am going to try this if nothing
else becomes available.

Re: [Repeater-Builder] help I need

[Mike WA6ILQ]

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 bought a old one at the thrift store for $1 just to prevent
the flack from the wife).  Anyway after soaking the epoxy
in the acetone for 10 to 12 hours an xacto knife tip will
pop out the epoxy.

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.

It's kinda hard to tune anything without power.  Yes, some
equipment (like low band Mitreks) have preset positions you
start from, but fine tuning always has to be done under power.

Circulator theory - well worth reading - is at


There is info on the mobile circulator at

Look under "step 5".
