[Boatanchors] SP-600 DMK-1

Hi Dutch,

Sorry, no solid info, but I'll make a couple of educated 
guesses.  Diversity modifications probably mean that minor 
changes have been made to allow multiple receivers to share 
AVC and detector audio outputs.  The RX with the strongest 
carrier will quiet the others via their AVC's.  "M" and "S" 
on the switch most likely stand for "master" and "slave."

The only visible differences from the standard SP-600J, are 
the switch on the upper right and the white and green wires.
