Boo hiss Motorola...Duplex, think the RF deck is a Motorola now...could be something else though.
Yeah, 440...amateur FM repeaters are from 440-448 with a 5MHz positive offset.
I got my start in electronics in radio, I was more comfortable with 50 ohm impedances before I ever got into ones 8 and lower //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif Just don't ask me to read a Smith Chart...please...//content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

I'm used to working in the 450->469. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
Audio is my love, but RF will always be a mistress...
If you have interference problems just throw a tone on it, can help a little if it is opening up the repeater.
Otherwise just get yourself a can and tune it on the receive. If you want one I might have a small rejection filter laying around I could let go for cheap cheap cheap. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
