[Motorola] MRS2000 Questions...

[Eric Lemmon]

I guess you're asking about an MSR2000 station (not an MRS2000).

The repeater station has a different exciter than a base station, and it
also has a squelch gate module.  You didn't state whether this is a VHF or a
UHF station, so providing the model number and installed modules will be
very helpful.

Subject: [Motorola] MRS2000 Questions...

This is a repeater not a base, 110w continuous duty PA, has all the shields,
even the part numbers all say its a repeater, but when i opened it up i
found out otherwise, etc... 

The first problem is for whatever reason Motorola made it a simplex remote
base, they put in a T/R relay and connected to the PA output and receiver
input. No problem there i can re-cable it.

However, i can not for the life of me get the receiver to stay on when the
transmitter is on. I pored through RBTIP and searched on here like crazy,
and i cannot find the answer. I pulled the receiver board and the jumper
JU101 is installed, this is supposed to keep the receiver on continuously,
and i installed jumper JU103 in hope that was it, JU103 keeps channel 1
selected in the receiver, that still didn't help.

I set up a signal generator and fed it with a signal and 1khz tone just to
give me a reference, when i transmit with the mic, the tx momentary switch
on the control module, or key it with the PTT connection on the backplane i
still loose the receiver audio. I think its actually just muting the
receiver to the local speaker?? If so how do you disable that??

Ok, next problem.

The second problem is i can't get this damn thing to encode a PL to save my
life. It has a TRN5073A PL Board which is supposed to be a full duplex
board, encode and decode at the same time, i think its a jumper problem or
something else as i can get it to decode just fine but no matter what PTT
line i use i cannot get it to transmit a PL. I have swapped the reeds with a
few other spares of different frequencies, still no PL on transmit. So it
doesn't appear to be due to a bad reed. How do you make this board encode
and decode at the same time??? Can't find it in the manual i have anywhere!!

Offer up some help!

Thanks...
