[Hammarlund] RE SP600-JX-17

[James A. (Andy) Moorer]

Oh good heavens - that is WAY too, too powerful for alignment. That will 
light up all the bands - you will hear the signal generator everywhere.
For alignment, no more than 1 millivolt or so is more than enough. You 
really want to be careful not to overload any of the stages or you will 
get images that will drive you nuts. Under no circumstances should you 
apply more than "a few" millivolts to an antenna input. Don't forget 
that the maximum overall gain of a sensitive receiver from antenna in to 
600-ohm output will be over a million. Easy to overload.

I would suggest making sure that all the bands work properly before 
trying to align it. They will just fight you and give contradictory or 
misleading results if some of the bands are not working right.

Enjoy!
