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

[Cecil Acuff]

Top of the heap....Sherwood SE-3.  Treat yourself...

Next in line....PD-2

Also there was a VE making a kit...Jan Skirrow, think he was a member here 
for quite some time.  External Syncro/product detector.  Worked real well as 
I understand.

Then there are the various mods you've read about that utilize the BFO to do 
SSB that are slight improvements on just using the radio as is.

You will no doubt get many emails telling you it works fine just like it 
is...and in a fashion it does...it you desensitize the radio by backing down 
on the RF gain and what not...

It works but really...the radio was never designed to do SSB.

There are also a few product detector mods which are probably worth looking 
into further.  Problem is they are radio specific.  You mod that radio and 
that radio alone works...but if you have several radio's the external 
approach is a better choice.  (SE-3 or PD-2)

Just my opinion though...

Merry Christmas and Happy New Years to the group!
