Philco 40-180 Compensator Alignment
#11

I will check but wouldn’t it be highly unusual to have the same issue in both of the two 40-180s I have? Further on the alignment procedure though (see pic below), I have a few questions… be gentle, I’m a newbie.

On Op 2, Note D it references the “high frequency oscillator compensator” … is that 21A?

On Op 3,4,5 there was a March 2022 thread that suggested the labelling of 19 and 19A should be reversed. I will make that change.

In the paragraph above the table under SIGNAL GENERATOR, last line, it states “It is necessary when adjusting the padders that the receiver be left in the cabinet”. Do you think that it should have read “that the receiver LOOP be left in the cabinet”? 

Finally, I assume that both the SW receiver loop under the top of the cabinet and the statically shielded loop antenna (ie the brown paper cylinder in the lower portion of the cabinet; see example pic below) should both be connected when doing the alignment.
