[R-390] A Few R390A Issues

[Jim M.]

#1  There is supposed to be a little spring across the two halves of the
Oldham coupler (on the PTO shaft).  If it is missing, there will be some
play.  Sometimes it gets lost when others have worked on the radio.

Hello  The restoring of my R390A nears completion I have a few issues that
remain.

#1

The PTO won't stay zeroed.  I put the dial on a calibration point then snug
the "Dial Zero".  Turn the PTO till I get a Zero Beat then totally release
the "Dial Zero".

If I turn the PTO upward 10-20 KHz upward then tune the PTO downward the
zero point has now change 10 KHz. The PTO has slop in that the when turning
the VFO the Dial doesn't  move with turning it. About a 1/5 of a turn
slop.........is
this typical?

#2

 What are the wire colors that are attached to the Audio Level Meter?

Left Terminal  Red/Wht         Right Terminal    ????    as viewed front
panel.


Many Thanks

Bill KB9IV
