[Boatanchors] SX-28 IF Alignment

[Richard W. Solomon]

I am ready to align the IF on this old gal and downloaded the N6PY
Alignment procedure. It says to inject a signal at the Stator of C1.1.
Now my schematic of the radio does not show a C1.1, where is it ?? 
I can guess that I should inject it at the mixer, but before I mess up,
I thought I would ask. As a note, WWV at 10 MHz comes in, readable (S4) 
with about 6' of wire attached. Hopefully, I will not have to do much tweaking. 

Thanks for your help,
