things are done .  I had Scott build my 220  Motorola Micor ,  a few yrs
back . I have only been to see it  a couple times just to dust it off , It

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?

To reactivate your missing features (Female Voice, Schedular, etc)
Simply key your mic and enter the Secret Code 9213528835. The controller will 
respond with OK. 
This does not require the controller be unlocked. DO NOT UNLOCK THE CONTROLLER.

Chances are... (cause I wear a silly grin...) depending 
on the age of your EEprom chip, it might be tired, failing 
and need replacement.  If the voice messages are set up 
to play as macros under DTMF Command then it's probably 
one of a few things.  Failing to act on a DTMF Command 
might be a level issue. But the wrong/no voice response 
to a regular controller function is once again probably 
more related to the EEprom starting to go south. There are 
a few other possible options. 

There are two Yahoo ACC Controller Groups, both have many 
of the same members, one is larger than the other and 
sees more action. I might encourage you to locate and 
join at least the larger of the two. 

I can and would burn a replacement EEprom for you if 
you supply the EEprom and pay the postage. Paul at ACC 
Repairs also sells preloaded chips and that's a fast 
and great way to go. Plus Paul is a nice guy although 
we don't normally tell him that in public.

Re: [Repeater-Builder] 220 repeater

[Matt Kassawara]

Dan,

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,  
but at our shared mountaintop site, the Mastr II performs much  
better... almost a night and day difference.  I'm also impressed with  
the audio quality.

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-
which has no power control feedback loop and no high-SWR protection.  You
get what you pay for...

Re: [Repeater-Builder] 220 repeater

[Oz-in-DFW]

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 getting
$25/ea for.  WA5VJB did a nice interface board for them. 

There are also a number of Kyodo/Nokia BSR 220 radios out there. I sold
a bunch of them, but I don't think I have any more. Might have one. 
They are almost as good as the Moto/GE option and are synthesized. An
EPROM sets the operating channels. I have docs if you need them.

There are a lot of surplus duplexers and combiners floating around from
failed 220 trunking systems.  Keep an eye peeled. DB built a short vhf
high split duplexer that's a snap to convert to 220.  If you find a
narrow spaced six can dupe on a  channel above 160 Mhz that is about 12
or 14" tall, it's probably one of these.

Be VERY careful connecting Dc power to the back of the radio. The power 
plug is not marked as to polarity, but I believe that the pin closest to 
the center of the radio is the positive and the pin closest to the side 
of the radio is the negative. Verify this. The type of connector used 
is similar to what older CB sets used to use and they are available a 
Radio shack. Radio Shack sells a double ended cable, be absolutely sure 
that you use the correct end if you get one of these cables.

RE: [Repeater-Builder] Re: MSF 5000 Army MARS repeater, Portland, OR

[Eric Lemmon]

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 and
the voltage when this problem occurs?  The power supply may be unable to
supply the needed current.

RE: [Repeater-Builder] Re: Sinclair duplexer

[Eric Lemmon]

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
for the Q202G duplexer, and they are noted on the above drawing.  Basically,
the low-split harness has 14 inches between tee centers, and the high-split
harness has 12 inches between tee centers.  The lengths of the cables that
connect to the repeater's RX and TX ports are generally non-critical, and
ideally should be long enough to reach those ports without any extensions or
adapters.  When the low-split harness is installed and the duplexer
carefully tuned, it is an excellent performer on 2m.

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
