Here is what I have Bill:
Squelch Gate - Guard Tone Decoder - F1-"PL" Control Module - Timeout Timer -
Station Control Module - Spectra Tac Line Driver Equalizer, in the vertical
slots and just the R1 Audio module in the horizontal position.
I have another card marked F1 Control Module that is not installed. And a wide
card marked simply Line Driver not installed.
No Horizontal PL card.
The controller is not included, I plan on using a port on the ARCOM RC210.
I have 2 manuals, the E40C and the E50C.

Stan,
Ugh!
That will make it extremely difficult to figure out what is going on. What
cards are in the cage?
Typically it should have PL card and R1 Audio card (these are installed
horizontally above the normal vertical cards), Squelch gate card and Station
control card. It might also have a time out card and Line card.
Is the pacific research controller with the repeater?
I'm not sure where to tell you to start. Examine each card for any mods.
Collect as much documentation as you can about what was done.
Basically a controller requires a COR signal from the receiver, a PTT to the
transmitter, Receiver audio going to the controller, TX audio from the
controller to the transmitter, and a PLL indicate. If the controller is still
there you can work backwards from there. There are several places where these
signals are available. Either on individual cards or from the backplane. Look
for additional jumpers on the backplane. In original condition there are NO
jumpers from any of the backplane pins.
Get yourself some manuals. I can try to help you as much as I can. The
receive signal flow is from the receiver to the R1 audio card. This card has
the local volume control and the squelch control. It provides the audio amp
and squelch circuitry for the receiver. From the receiver the signal also goes
to the PL and Squelch gate card. The PL card decodes (and provides receiver
filtering if so jumpered) PL and sends it to the Squelch gate card. The
squelch gate card processes the audio from the R1 card and sends it to the
transmitter. It also provides the transmitter keying signal. The keying
signal goes to the Station control card through the front panel card controls.
From there it goes to the transmitter. There is also circuitry for delaying
the de-key of the transmitter to accomodate the reverse PL burst.

Thanks Bill,
But that control does nothing either.
This repeater was used with a Pacific Research controller before that has a
squelch circuit built in. It did not come with a squelch card. I don't know
where to look for the problem...

The squelch gate card control tells the transmitter when to transmit. The
squelch control on the R1 audio module gates the receiver squelch noise.

Yesterday I finally plugged this MSR2000 in with a dummy load on it. It
came on with an open squelch and went right into transmit mode. The squelch
control on the squelch gate card did not close the squelch. I cannot find any
way to close the squelch. If I pull the squelch gate card out it quiets the
squelch.
I hope it is not a defective squelch gate card.
Any thoughts? This is my first experience with the MSR2000.
Thanks
