Philco 118 alignment issue
#19

I installed the shadow meter and did the alignment again.

The SW alignment seemed to be better, although the SW oscillator trimmer cap seems very touchy.

The dial calibration for the SW band is more accurate now and I no longer have the problem of picking up my RF generator at two points on the dial close to each other. I suppose the shadow meter coil may also act as a filter for the RF preventing it from getting to the rest of the circuitry.

I also checked and the meter action wasn't that good so I re-magnetized the magnet (mine is a small bar instead of the horseshoe magnet) and the meter action is within spec.

Is there any proper way to make there be more shadow movement between being tuned on a station and not tuned on a station?

EDIT:

I got another issue that just cropped up.

At 1500KHz on the dial my RF generator has to be set to 1455KHz in order to receive a signal and the oscillator trimmer cannot adjust it enough. The low BC band oscillator trimmer can get it on 600KHz.
