Found them, not off frequency, just add the 5. Thanks.

Subject: [Repeater-Builder] Spirit MU21CV Radio Frequencies
I know this is a bit off thread, but
I have seen where elements are sent out for re-crystalling (different
freq) and come back with a stick-on label showing the new freq. Maybe
the labels came off, revealing a freq that is no longer in the element?
(I've actually had this happen to me before.)

Sorry this is slightly off-topic, but just so Dave Cameron gets a fair
trial in the court of public opinion...

Xtal cases seem to be intact, was told they xtals were still in there. Even
so, I get no power output, and it does not even register a frequency on my
freq counter. So no output, and no input. There is one extra plug at the
control head, and a purple wire with a connector on it.

Me too, sometimes I need to open the case and read what is printed
on the crystal case itself. Other times, I look at the produced
signal from that Channel Element on the spectrum analyzer and
calculate what frequency it is on.

I don't think it is a xtal issue, I think like someone said, I am missing a
ground or something, something that makes the final connection between the
radio and the control head. But I'm not sure where to look.

You may want to determine if the Channel Element frequency select
wire (one of the pins on the bottom) is properly grounded.
Look at the bottom of the circuit board immediately below the
Channel Element and locate the one connection that goes to the edge
connector P-902 on the
If I understand what you are asking, pin one of each board is ground on
here. There is a ground wire on the power connector that is connected to
ground. Is this what you are referring to.

Ok, I think I'm getting the picture, it the P-902 the power connector in the
fron of the radio. On one of them there is a wire that comes from the board
by the transmit xtals that goes to the front of the radio, and is connected
to ground.

Rather than trace everything out, just pop the shell on the
control cable.
Trace pin 1 and pin 4 up to the head. Pin 1 is ground and is
hooked to the shield of one or more of the coax conductors in
the control cable and ends up on pin 21 of the head. Pin 4 is
frequency 1 and ends up on pin 11
Nope, nope, nope ...
Exciter: frequency 1 select wire from the Channel Element on the
circuit board goes to P-902, pin 15.
Receiver: frequency 1 select wire from the Channel Element on the
circuit board goes to P-904, pin 2.
Those specific pin numbers must be grounded
Thank you Mike,

RG-400 isstranded center conductor. If you have a solid center conductor, it may be RG-142 that youhave. RG-400 and RG-142 will give about 75 dB isolation from leakage. Foil braid shielded coax will give about 90dB. Hardline (solid copper tube) will give about 110dB of isolation.
So, hardline
Does any one have a squelch mod for the GE Master Exec II that will
improve the squelch action and 'mobile flutter'. I used the mod on
the repeater builders for the Master II and it works very well.
That's changing out a .82 cap to a 3.3uf. I'm looking for the mod on
the Exec now.

it sounds like you do not have all the assy's for the radio. you would need
a control group book and a connector tool to rearrange the cables. The best
bet is to get the rig over to someone close to you that has a working test
setup to check the rig. Or get a non scanning 4 channel cable and head
Well from what I see, that is what I have, the head that has the volume and
squelch also has the 4 channel selector with it, as well as the power
button. But if I unhook the the scan head, then the volume goes nuts. I
have no way of knowing if this was all that was with it, they were just
given
Let me ask this, I have two control boxes on here, the first is the scan
head, then there is the actual control head that has the volume control on
it. The wires you mention are going to the scan head. If I take Pin 4 to
the connector #11 on the scan head, the volume goes sky high. Pin # 11 on

Matthew,
I have a manual for the MICOR mobile radio. (I'm assuming this IS a
mobile?) I'll scan the pages for the wiring pinouts for the control
heads and send them to you.

Thanks Mark, that would help. I am sure it is something minor. I want to
try and convert one of these to see just how much work is involved. A
project if you will.
