[Motorola] UHF syntor front end

[Mike May]

Did you also tune the receiver LO injection or did you leave that as tuned
for the stock 450-470 band.  It sounds like the receive mixer level may be
to low for the downbanded region of 440-450. It's been years since I've
worked on a syntor but this may be your problem and I don't have my syntor
manual handy otherwise I could tell you where the Local Oscillator tuning
is.
