Transceivers:
If you don't want a boat-anchor of a GE or Motorola, look for a
Motorola R1225 repeater transceiver -- not the GR1225, but just the
R1225. It's the actual repeater and cheaper. I have run several for
years. Run them at 50% power and use good forced air cooling and
they'll survive. No, they're not a Micor, but then again, the Micor PA
was pretty much designed to run continuous duty into a short/open
circuit :)
Though the other guys are right. You can't beat a big old Mastr II,
Micor, MSR2000 or even MSF5000, etc. for tough and reliable. I just
don't like buying my repeaters by the pound anymore!

I have long considered building my own 2m repeater out of 2 Icom
2100 or 2200 back to back thru a repeater controller, using a good
duplexer and a Comet or Hustler antenna. Here are my questions:
1. Nobody seems to like the Comet or Hustler antennas. Why? I
have no ice here, lots of wind tho.
2. Why is a 50w 2m transceiver, derated to 25w and driving a power
amp a bad choice? Or is it OK?
3. Any suggestions on how to keep the duplexer cavities affordable?
4. Which repeater controller? Or is that a religious question?
Anything else I should be wary of?
