[Hammarlund] Alignment Of HQ-180 IF and BFO

[Byron Tatum]

Hello-
    Today I performed the alignment of the 60 KC IF of my HQ-180 per the manual, 
with switches in USB, BFO in center at zero and 0.5 KC bandwidth as called out 
for. I have different pitch when switching between USB / LSB,  the difference is 
great , there must be something off. I set the BFO to 60.0000 KC using sig gen / 
freq counter.
    I have heard mention of a recommended IF alignment procedure, possibly 
different from manual. Does anyone know about this?
                            Thanks, Byron.
