[R-390] Best approach for SSB mod on R-390A

[Dan Merz]

Tom,  I concur with Ed's comments.  I used the two diode mod for a while,
worked pretty well except for agc and very strong signals which made manual
tweaking of the rf gain  necessary.  I later made the outboard ssb adapter
that Ed mentioned and that's been good enough for me.  I've used it with
both the 390a and 390.  The 2-diode mod is very easy to do/remove.  The
outboard adapter is more of a project and needs a small power supply,  which
I built right on the adapter chassis.   Dan.

What is the suggested approach for SSB modification for the R-390A. 

Is the 2 diode modification worth attempting?   I know it has been 
covered here more than once just wanted to solicit the current thinking on
the matter ... thank you ... tom, N3LLL
