[Elecraft] Signal generator for K2 alignment & test?

[Tom, W6WW]

I've gotten to Alignment and Test Part II at the end, but I cannot find a
signal off a long wire antenna.  Also, I get such a weak signal at 7000 kc
that it's not much use.  I suspect I need a signal generator to go signal
tracing, but have no idea where to look for such a machine.  Can I use an
antenna analyzer like the MFJ 259 as an rf source or do I need a different
piece of equipment?  Any tips as to where to go shopping would be
appreciated.
