Milt;
I believe it was to change operation from PL operation to CS operation, not
just receive, but 'repeat' also
IOW, change it to a carrier-in operated repeater

I suppose that it could be used for that also, I have previously only seen it
used in base applications but the card is a 2 state device and could control
many things.

Get Rid of that crap cable your using..
I only use RG 214, and or superflex for my inter connects between the
repeater, amps in line(power amp/preamps), and the duplexer. Mosly 1/4
superflex becuase I got lots of it. In a pinch I will use RG-142... Never use
that 400 or 9913 garbage..
I dont know anything about this particular Tower or how and when it was put up.
if its a sleeved tower like a Rohn 25g or 45,55, Universal.
I always apply Lithium Grease at the joints. This Helps putting up and taking
apart towers in the Future. this also a creates an Electrical conductivity
RG-400 is the same as RG-142 except has a stranded center. It's not crap.
LMR400 is crap, but that's not what he said.

Is there another vendor/OEM we should be looking at?
TX-RX would be my suggestion. My only pet peeve with TX-RX duplexers that
on the duplexers that use garden variety 4 cavities is that they have BNC
connectors instead of type N. If you opt for their Type N connector
upgrade, you just get three BNC to type N adapters. Their larger
Thanks for the comment to Neal about the cables. RG-400 and 142 are very good,
quite common, and very reliable. If you take a look at the specs on 214 and
400 you might note that the 400 is rated att 98% shield where as 214 is at 96%
for whatever THAT fact is worth….probably nothing. - Mike
Sure, I would appreciate a starting point.

I missed that in my readinggetting older need glasses..
I thught you said LMR. the 400 cable is RG-400?
Im loosing it. I still prefer superflex hardline or 142 for interconnects.

THats what happens when I dont wear my glasses.. I thought he said LMR400..
142 is Good.. I still prefer superflex.

28-69-02A (or B), garden-variety 4 4-cavity pass/reject, fixed loops, BNC
connectors, the typical duplexer for 3 MHz split applications. The only
difference between A and B is the mounting brackets (one is front-mount, the
other has added brackets for rear-mount).
28-69-01A for 4-cavity 6-5/8
Superflex WOULD be NICE…but I had to do this project a bit more ‘under the
radar’ if you know what I mean. And the superflex was more expensive at the
time. I was able to get the 400 for near to nothing. - Mike

Were looking for someone to tune up a Motorola Mitrek
to the Amateur bands. New crystals is installed. We
thought about doing so ourself but the river is real
close to me and were afraid it might end up there if
something goes wrong. You can contact me off line if
you like my address is good on
Correct. This is the application we are planning on using it for.

It is the EXACT same board, same frequencies (1550 and 1450), same pinouts,

I think the only difference was the slot you plugged it into, and setting

Fortunately, the manual for these three cards (PL control, Repeater Control,

Not often in the Low Band, non-unified, but is in most manuals.

I believe this unit is a Falcon 8252 220 Mhz power amp, 10 watts in, 100
watts out, continuous duty.
Production date was around 1989. It uses F1260 devices and a couple of
2N7000 devices on the control board. The rack panel dimension is 8 3/4 x 19.
If this is the hardware you have
