[R-390] SP-600

[rbethman]

List,

The problem with all this additinal SP-600 info is that my SP-600 is one 
of the Northern Radio versions.

Most, actually about all, does not apply.

The Northern Radio Variant is a J-11.  No JX version at all.  It is the 
first diversity version and is a bit of an oddball.  There are no 
crystal switches, and it used a Master Oscillator along with a second 
SP-600 by Northern Radio to work in diversity.

Very little is common with the JX series.
