[R-390] Single Sideband reception with the R-390/R-390A

[Barry]

I have a PD-1 but thinking of selling it because I just don't use it.
Nothing wrong with it, but I find it easy enough to tune sideband with the
existing, non-modified radio.

The other thing I've done is feed my Kenwood TS/440SAT with the 455kc
output, tune the 440 to 455khz, and listen to sideband that way too.  Of
course I have to remember to tune to 455khz because I can't find 455kc on
the 440 ;-)

Gentlemen,
I would like to thank all of the people that responded to my signal
generator question a few days ago. I received responses within minutes of my
posting. Unbelievable! That is what makes this group so great. I would now
like to open a discussion about single side band reception with the
R-390/R-390A series receivers. For the purpose of this discussion let us
assume that the radio has been altered such that the AGC has been modified
for proper SSB reception.  I have had experience with:
1) the radio with no external adaptors and increased BFO injection.
2) a CV-591A SSB adaptor.
3) a Hammarlund HC-10.
4) a Central Electronics Sideband Slicer.
5) a Sherwood Engineering SE-3
6) a PD-1.
I have not had any experience with the Capt. Lee onboard product detector
mod or a couple of the home brew units that are out there. I have schematics
and have ordered parts for one of the home brew units I just have not had
the time to build it yet so I can not comment on these. The adaptors that I
have mentioned are not necessarily in any particular order as far as
favorites, I just listed them as I thought of them.
They all work. Some work better than others, and some folks can probably
detect differences in the various units better than my tin ear. That is
where you guys come in. I am curious as to your experiences and what you
feel are the best units. Maybe we could rank the units that I have
mentioned. Some units require external hardware to operate, that is,
external amplifiers etc.. Some units will allow the audio to be fed back in
to the receiver at the rear of the unit. Much has been written about the
quality of the stock audio but I have found that the audio is quite
acceptable if the audio deck is altered using Mike Murphy's suggestions. Any
thoughts? Please respond to the entire group, it will be interesting to see
what everyone's experiences are.-Brad
