Good evening,
Your e-mail brings up one question: used duplexers for 220 where?

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.

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,
Dan
