The photo shows a Mocom 70 outer housing and a 4-frequency
control head plugged into it.
There was also a cable kit and a different control head that
allowed the radio unit to be installed in the rear of the vehicle.
Motorola had a habit of using outer housings with different internal units.

I went to the site and downloaded the zip file. Figure 8 in the PDF

identical. While there may be minor circuitry differences to satisfy

I have one of those also. It was given to me by someone that knew I did work
with radios. I remember seeing these back in the late 60's, or one very
similar to it. It had an extend feature on it. Mine is in the VHF band. It
would take a lot of CPR to get or keep them running I would think. Just
And one of the most dependable radios Mot ever built.

Anyone know off hand which size of the Anderson Power Pole connectors is
used on the MTR2000 repeaters?
I'm guessing the 75 AMP, but want to confirm that before I put in an
order. (It will be Tuesday before I'm back in a position to measure one).

You gentlemen have really made me think about the pros / cons of the
DB314. After talking with my tech partner on this project, I think we
are going to go with a DB224 and DB408 or DB420 combo for the remote
antenna. It really is overkill for a remote antenna, but since we
will be given a
I have used many of the DB408 420 antennas in the past and have never had
a failure. That was back in Oregon and we used the antennas for the site RX
Multi coupling and TX Combining system. We always used to make a slot for
the hams to run through the combiners and had mo problems doing so. Since
Chuck,

Well, changing out the backplane got the repeater working... along with
double-checking the jumper settings one the cards.
I did find a couple of jumpers that needed to come out on the Station
Control card, and I'm sure that helped.
The machine still does not pass audio, so now that it is
any idea of a part number for this type schotky diode for this purpose?

Now you are learning how to properly work on motorola equipmenttrial error
By fixing it the way you are, problem by problem, you will know the repeater
in and out so it will be easier to work on in the future.
Sounds like you are almost there if you only have an audio problem left.
Hope you
Hi,
Does anybody have any extra A+ power cables for Motorola T83/T84 Spectra high
power radios, for a couple of ham project radios i picked up?
Cut-offs or complete.
Don't need fuse holders or fuses.
Thanks,
Mike
I have a bunch. How many would you like?

After STRUGGLING with a controller, the name of which I will withhold to
protect the innocent, I am frustrated. I was told it had good bang for the
buck. I want to be able to control a freq agile radio such as an FT-100D to
act as a remote base, to work fm on 10, 2 or 6 or 440 from my repeater.
Mike,
I have standardized on one part, the 122NQ030R made by International
Rectifier / Vishay. The datasheet is here:
www.vishay.com/docs/93210/93210122.pdf
This Schottky diode has an extremely low forward voltage drop, and it can
handle 120 amperes. I generally use the R suffix version, where
The MTR2000 PowerPole connectors are definitely the 75 ampere version. But
be careful: Before you cement the housings together, note that they are
arranged one over the other, not side-by-side.

Mark,
OK, now back to where we started from, but much better.
I have a bunch of questions for you.
1. Do you have a local speaker hooked up? If so do you have audio out
of the speaker in either carrier squelch or PL mode?
2. Do you have repeat audio in carrier squelch mode? I know you do not
Has anyone ever converted one of the DB Products 4001 highband pass
cavities to a 222 pass or pass notch cavity? I know DB makes or made a
222 version of that mocel but wonder if it is feasible to cut one down
and make new loops. Appreciate any info. Please reply to

Well, Joe - I got it to work!
What I ended up doing was chasing the audio path from the goes-inna
through the backplane. I found that on the Squelch Gate card, it was not
being passed, even though the jumper was in place. I added a hard-wire
jumper to the backplane between Pins 11 and 24, and

Thanks a lot.. I will take a look at that one the web.. The -- one we
have has some desirable features but if it won't do what it is supposed to
it is sort of a waste. I just can't figure out why it won't change freqs.
Has to be a hardware issue, wiring issue or procedure I suppose. - M
Mark,
Congratulations on your progress! However, I am curious about your comment
that the repeater is not passing the PL tone through, On a community
repeater, wouldn't you want the input tone filtered out of the audio chain
and recreated fresh for transmission? Not all community repeaters use
