[R-390] EAC R-390 factory modification that incorporates USB/CW/LSB

[Dennis Wade]

I have a Motorola that has the 6U8 module behind the front panel.
Don't know about the "Mexican Military" story.  The IF deck is EAC
though

  My version still has the BFO knob for CW, but has USB/LSB/AM choices
as well.  The IF deck has a new connector up by the ballast tube which
connects to the module and the expanded mode switch.  I've had mine
for almost 15 years now.  Works reasonably well.  If it wasn't a
factory job, it was a very well done depot mod.

I'm not sure how rare it is or isn't though.  That would be
interesting to know.  I think Chuck Rippel made mention of it on his
website.
