MHz split? Putting a new machine on the air and need to know if I should go
with a 6 cavity duplexer to give me the 100 or so dB
I have seen that supply on Micor repeaters.

be done away from the office. Seems the sound was getting to the
administration area of the building and we were disturbing their afternoon
nap LOL.

Just bought a Kenwood TK820 UHF repeater... Any suggestions on how to
get it programmed for the ham 440 band? Local resources in Northern NJ.
Program it myself? How do I go about doing this?

Thanks to all who responded.
Now, someone else has the nice aluminum case,
He seemed pretty happy about it.
So much for learning the hard way, It wasn't very painful at all.
Thanks Again,
David
