[Hallicrafters] SX-100 MK2 Alignment

[David C. Hallam]

I have a question about step 5-3-2, alignment of the 1600 KHz oscillator 
and 1650 KHz IF.  I think I have carefully followed the procedure in the 
manual, but can not seem to get the IF peak centered in the pass band.  
I have peaked and repeaked T1 and T2 as well readjusting the 1600 KHz 
oscillator.  My adjustment was to turn the slug into the coil until the 
crystal stopped oscillating, then back the slug out until it output 
peaked.  When I reached the peak, I kept turning it out until the output 
voltage as measured by a VTVM on the detector voltage dropped to 1/2 of 
the peak voltage.  After than I peaked top and bottom of T! & T2.

The pass band center is about 1/3-2/3.  Have I done things correctly and 
how important is pass band centering?
