Batboard

Hi All,

I did a search here on batlabs and other sites for this, but it seemed a bit vague on anyone's results with this radio.

What I'm looking for is if anyone has been successful in retuning the duplexer that comes with the Med Micor (in the extended housing) for the ham 445-450 band?

Just want to check to see if it was worth the time to go through it or just remove it and put in a phelps dodge commercial mobile duplexer.

Working on building a duplex UHF ham radio for the truck, came across 2 of these radios new in the box.

Thanks, -Steve/WA6OXN

I am currently using a set of micor duplexers in my UHF repeater in NC - They /do/ work, but.... They are very lossy when they get down to the ham range due to the fixed, soldered matching sections between cavities. The only real issue that I had with them was having to "flop" inputs on them - since my repeater was tx high/rx low i just reveresd the tx/rx inputs and had no real problems. They are also BpBr, so nut really suited for high-ambient RF environments.

Hope this is of some help

Tried to take one down to the 430mhz-420mhz part of the Ham band -
did not work !!
