Well Al, you were right 2 times OM! You told me the 2nd IF [L31] was
peaked on wrong side- right. #2- you told me to disconnect the wire
going to VFO- Xtal switch. That was it! 

	Alignment on band 5 [14 to 29mc]- is good up to 21mc. Not completed,
but tracking is now short. so far good linearity up to 21mc. 

	This is a weird problem, must be bad caps in the FFO module. i see
c64 is a .01uf. i did not take this apart! 

	Now acting like an SP-600. thanks to all who wrote in 73s Russ
