That is a Q202G style duplexer. The 7 diameter cavity is actually 6 5/8 OD
and the can length is 24. The 32.5 is for the length of the rod extension.
The proper VHF can for going down to 132MHz is actually 26. The best harness
is RG214/U with crimped Delta connectors - not sure if it is a
A drawing of the Sinclair Q202G duplexer harness is found here:

Remember that the calculated length of the jumpers must include the length
of the coupling loops inside the cavities. Sinclair made only two harnesses

Happy new year to all of you out there...
Maybe somebody can give me a hint on the MRTI connector in
the MSF5000?
Reading the article on the best way to interface an msf5k,
i try to check the MRTI connector on the SSCB (j802).
Audio is there, but the PTT doesn't work. I got the thing
I have tried the output direct to a dummy load same result. I use tone access
which I turned off and set the machine to squelch open, same result. ???

Is it possible that the changing of operation frequency to MARS has caused
the PA to become unstable and the resulting spurs are causing the protection
circuit to dial back the power? Look at the output on a spectrum analyzer
when the power loss occurs. Also, what happens to the PA current draw
Remember that the calculated length of the jumpers must include the length of
the coupling loops inside the cavities.
This statement does not apply to the Q202G version with the Q loops with the
Johanson capacitors. It applies to Pass Cavity interconnection cables or the
symmetry frequency
Try turning down or off the individual denounce times per pin within the
accessory settings. Sounds like their set to around a second or so.

Be VERY careful connecting Dc power to the back of the radio. The power

ring or chassis mounting hole then touch the other end to both power pins. The
one that reads zero ohms is ground.

All right folks,
For those that run a 220 repeater, what are you running as far as the
machine itself?
A local group is looking to put a 220 MHz repeater on the air and
would like some ideas.
Thanks,

Could be as simple as a dirty voltage adjust pot (R7)
if you need the schematic, I can probably help.

Micor converted to 220 works very very well. Exceptional receive and excellent

Micor conversions work very well, but are rather involved.
MVP/Exec/Mastr II conversions are much easier and work as well. The MVP
package works out really well.
Both the Motorola and GE radios rely on a different PA. Most use a
hybrid brick to get power. I have several of these I've been
Dan,
I have a Hamtronics REP-200 at a mountaintop site that has been
trouble-free. I am using the stock 15 watt PA, and the coverage is very
good over the Central Coast of California. One precaution I took was to put
a single ferrite isolator on the TX output, to protect the PA transistor-
ok thanks im gonna read the radios with the cps to check the settings, will

I recommend converting a high-band GE or Motorola. My club recently
replaced Hamtronics gear with a converted GE Mastr II after
experiencing considerable exciter microphonics and receiver desense.
Hamtronics gear probably works fine in a clean and quiet environment,

this worked on my 85 it did the same thing
So it look like the general recommendation is a converted GE or Micor.
That is kind of the direction I was leaning for the group.
As for conversions, what are folks using for final amps?
