Hi All Building a Micor Repeater from Scratch Facts. Mother Board (unified Chassis ) origin unknown. Had to add a jumper for +12Volt to RX.
Rx with audio works fine. Not using pl board ( control system does PL)
Have great local speaker vol and squelch.
Exciter, Tripler, PA and circulator all are in working order
Have the following modules in the following slots counting from the right front.
Audio Line Driver Slot 1
Station Control in Slot 2
Squelch gate in Slot 7
I can Key the transmit on the station control module
The exciter and tripler key up and make power
PA power comes up about 2 watts and drops off
Power Control module check out in a known good complete Micor repeater.
Control Transistor is good and plugged in correctly. Checked voltages
Missing (- A Key ) minus A Key on the control module.
Station Control Module (-A key ) does NOT come up.
Station Control Module works in a known good micor repeater.
I can add +12 volt to PA control terminal on the PA and PA makes lots of Power
on the correct frequency but that bypasses the Circulator SWR protect etc
The intent of the whole mess is to use the minimum of the Motorala modules
since the
Sierra Radio Control system has provisions for Squelch, PTT, RX and TX pl etc
any Ideas??

Eric,
There is a list of the min required jumpers used in the MSR-2000
repeater station included in my MSR-2000 to external repeater
controller text found at the www.radiowrench.com/sonic web
site. Working from a decafe based hazy memory... there should
be 4 to 6 jumpers required on the back plane. And the remaining
modules need some specific jumpers and mods depending on your
choice of carrier squelch or ctcss (pl) operation, which can
be set up as selectable.
You're looking at placing the repeater into duplex mode, which
"normally requires" specific modules be in place with a number
of jumpers.
Buy a used Motorola Micor Repeater Squelch Gate off Ebay, swap
the end connector with an unused MSR Module and save big $
The big issue module combination wise is the transmit channel
element ground/enable, which can be provided by the wire-line
and/or squelch gate module. If you pull the F1-PL/Guard Tone
Modules in the wireline tone control combo.... or the DC-Transfer
module in the wireline dc current loop combination... you need
to install jumpers JU-5 and JU-6 on the new Squelch Gate Module.
You can Email me direct if you have more questions... or I'm happy
to answer them through the group if they don't drag out to long
and torque off the neighbors.
Removing the T/R Relay is no big deal so that's not a problem.
Great repeater if you align and treat it right...
cheers,
skipp
