[Hammarlund] SP-600 tracking alignment- answers

[Al Parker]

Hi Russ,
	Thanks for the info, glad it turned out OK.  I've been wondering what 
you might have done over the weekend.
	IIRC the FFO has 2 BBOD's in it.  Both bypasses. But I don't see how 
either could have caused the problem you had noted.  If disconnecting at 
the switch cured it, it must be some leak thru at the switch.
73,
