Philco 118 alignment issue
#25

It bothers me because originally the tracking was pretty much dead on for the AM band. Now the SW band was initially off as I tuned lower, but oddly enough after the problem with the AM band being off happened, the SW band was pretty much dead on before I removed and re-installed the LO coil. Have not checked it after reinstalling the LO coil as I couldn't get a peak at 1500KHz.

The end plates do have slots cut into them. I am reluctant to adjust them as the radio at one point did track correctly with things as they are and as I recall the high end AM band oscillator trimmer did not have to be anywhere near all the way out to achieve that.

I know something has changed, but I have no clue what it could be.

This happened shortly after re-installing the shadow meter. The initial alignment was correct far as I can remember, but then I noticed to receive 1000KHz I had to have the radio set at around 1010KHz which is also when I found the rest of the dial is off other than those frequencies I mentioned which are exactly correct to the dial reading.

I remember one time before re-installing the shadow meter after the initial alignment doing a check using a digital frequency display and very small value capacitor so as not to pull the oscillator which I confirmed by no drop in the AGC voltage at 1500KHz and at each number on the AM band the display showed the correct frequency maybe +/- 2KHz.
