Hi,
I found on a National RX one time that the oscillator was on the
wrong side. If it should be high, it was low or visa versa. Be sure
that is not your case as that will make tracking impossible.

I have a pristine NC-183D I picked up a year ago that I am finally
getting around to. Have replaced all the electrolytics and sound
really good. BUT...I cannot get it to track properly as I follow the
alignment instructions in the manual. I can set the top frequency
on each band with a small trimmer cap (this is the oscillator coil
adjustment) but then according to the instruction manual you adjust
the low end of the dial by moving a wire inside an inductor, which
does move the lower frequency but not nearly enough to get to the
frequency they say you should see. Has anyone else had that problem
during alignment of this receiver, or am I missing something. Have
checked the voltages at the first and second converter and they seem
fine and have pulled off the mica cap across one of the oscillator
coils (1.8 to 5 Mhz) and it checked just fine (supposed to be 1600
pf and reads 1615 pf). And have substituted a different 6BE6 in the
first converter and still can't get close to proper or accurate dial
tracking. I am 500+ Khz off no matter what I have tried. And
thoughts on this one! Thanks. Van, K7VS
PS I would like to hear from NC-183D owners that may have
experienced this problem or have some thoughts about what I am seeing. tnx
