[R-390] Theory Question - RF Transformer Alignment

[Mike Hardie]

I'm not having any difficulty performing the alignment, just don't 
understand what's happening.

When peaking the RF transformers the technique is to tune to a "lower" 
frequency, adjust the slug, then tune to a "higher" frequency, adjust the 
trim cap, and repeat as necessary.  I can understand why the two adjustments 
are inter-related, can anyone explain how it is that eventually both the 
lower and the higher frequencies are peaked?

In other words the slug adjustment seems to affect the lower frequency more 
than the higher frequency, and the trim cap the other way around.  If this 
wasn't the case the transformer couldn't be peaked for the lower and higher 
frequencies, every time one was adjusted the other would "move" too far.
