[R-390] More on the R-390 mod question.....

[Phil M.]

After looking further, the mod consists of the multi-pin Amphenol
connector being wired to the board with the 6 top hat diodes
which are connected to what looks like a position indicating switch
mounted on the end of the crystal oscillator subchassis.  I am
guessing that the mod was to provide some kind of remote indication
of the band switch position.  Anyone heard of anything like this?

thanks,
Phil
