[Elecraft] IF xtal replacement mod

[David A. Belsley]

Well, I replaced the 7 IF xtals and redid CAL FIL with spectrum analyzer. 
I guess the results are good, although I didn't do any before and after 
measurements.  The only negative is that my FL4 position, at 100Hz, is now 
much more attenuated relative to the other BPs, roughly one S unit.  It was 
somewhat less than the others before the mod, but not that much.  Any 
thoughts out there?

thanks,
