not all the emails to this group end up getting forwarded to
me. If you've followed the thread you know I did order one
that is not quite exact but should work. Thanks again

I have an old Phelps Dodge VHF Duplexer that has a
frozen air variable. The Duplexer is a part# 499-509 and
covers 144-174. The air variable in question is stamped
167-202 and is split stator about 1 3/8 square. Anybody
know where I might find a suitable replacement, I haven't

This is one of the toughest intermod products to solve. 2 transmitters
600 kHz apart generate spurs every 600 kHz on both sides of each
transmitter. When we were co-ordinating repeaters, it's one parameter

Most scanners have an extremely broad front-end and as such
would be extremely sensitive to de-sense. Hook it up and let it
receive a signal and then key a transmitter next to it and see what
happens.

I've not found a way on the 1600 to do that, I think they are similar.
The 1600 will measure the difference between the signal and the oscillator
setting but you have to know approximately what the signal is you're trying
to measure before it works.
