[R-390] A Few R390A Issues

[DW Holtman]

Bill,

That is a lot of slop. The first thing I would check is the Non-Mar clamps 
on the Oldham coupler. There are two of them, one in each of the sides of 
the oldham coupler. Make sure they are not cracked or loose. Cracked clamps 
are very common. If your PTO is slipping internally that much, you have some 
serious PTO issues.

Looking down at the radio from the front, the left side (outside of the 
radio) there is one wire, White with a Red stripe. . The other terminal has 
two wires the same color, White with Orange and Black stripes.

Best,

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
