[R-390] SSB on the R-390 series

[jlap1939@yahoo.com]

Dear Friends,

Had a couple req. for the method I have given, and
exploited..Happy to send...however, it is given in
basics in the Ops. Man. (TM 11-5820-357-10 ..for 390,
and TM-11-5820-358-10, for the 390a  I believe). My
additions relate to furthur set-up, as I learned from
my past ARMY friends..and a better understanding of
the width of the sideband signal.

I am really writing all  this in regard to my past
experience with the deviation +  or  -  for the upper
and lower sidebands. Mine is now BETTER.

Where in the past I used  +  or  -  1 to 1.5 hz, I now
find since getting my receiver back this last time,
that I just never vary from the figure of either +1 or
-1. I believe because it is devoid of any probs in
alignment and backlash at present...Does that seem
reasonable? It would seem to be best in using  a two
hz filter width on my  390. The 390a should use a 4
for filter usually...Seemed to me in mil. pratice that
the 2 width was very hard on the hearing, due to the
sharpness of the mech filter...Anyone else comment???

I would add, it is the same all the time, hot, after 3
hrs. or at 68 degrees after being off for several
hours...WHAT A RADIO...

Had a note asking about the SP 600...I find it works
fine on the 600; however it is simply not as accurate
or effective for my man. read-out....Might be much
better with an added ele. read-out. As I have said,
effectivness will vary from receiver to receiver..but
it should work pretty well on any. The biggie is to be
patient and learn the method. (Probably easier to get
an SSB conv. if you are not interested in using the
old method...)

Regards,   John   (JLAP)
