I should have mentioned the crystal switch in the upper right corner was 
replaced with the Dual Diversity switch.

You have to remember that many of the SP-600 receivers used by the military were 
the JX- versions that could be crystal controlled as well as the tunable 
feature.  Those JX- versions were usually used with crystal control for things 
like RTTY circuits.
