[Hallicrafters] SX-42 alignment

[Waldo Magnuson]

I need a little help aligning my SX-42.  In the RF alignment the first 
step is to adjust A21 (SAMS) or (C21) (service bulletin) for a maximum 
output with the signal gen. and the dial setting at 1500 KC.  I find a 
maximum output with the dial set at 1510 KC.  It seems like I should 
first adjust the local osc. but the alignment procedure doesn't seem to 
cover this.  I'm using a RMA dummy antenna on the input and a Simpson 
269 (5000 ohms per volt) across the 500 ohm speaker connections.  Help 
appreciated in the dial calibration.  Thanks.
