[Hammarlund] About aligning an SP600

[Chuckie]

I have an JX21 that I want to align. I would like to hear some feedback 
from members as to what type of sweep generator one should look for at 
the Ham Fests or online. I need one that will do variable markers seeing 
I have a transmitter that needs that as well. I need to drop markers in 
at 3.5 and 4.5 in the 80 meter ham band and different frequency markers 
in the other bands as well. Anyone have some words of wisdom as to what 
manufacture and model to look for?
Thanks
Chuck
