[R-390] Nuvistaplug?

[Steve Hobensack]

     Many years ago, I think it was Popular Communications magazine, I read 
an article on broadcast band dxing. The champion dx (the most qsls + 
countries) person used the Super Pro 600.  I have the JX-17 model. Raymond 
Moore's magazine "Communications Receivers" explains most of the differences 
in the models.  Most all of the receivers have the same basic circuit and 
performance.

Oh, I could go on and on about the comparative performance of the
R-390/R-390A as opposed to the Sp-600 (including you need 21 major
changes to get it right!), but to be honest, I’m one of the guys that
have been bidding unsuccessfully for an SP-600 on E-Bay, so I shouldn’t
talk. Indeed, the only reason I don’t have one yet is trying to decide
which of the 21 different models is best for MW DX’ing. I saw some down
in the Air Force place, and was not impressed with it’s ability to dig
some very weak signals out of the noise that you knew were there. But
for scanning for unknowns, it felt very good. A hassle converting the
tuning to an exact frequency. So anybody want to sell me their #5
SP-600? Maybe give me a better idea of the differences in the various
models off the group. P.S. Another writer sent me an e-mail at my direct
address about the Nuvistaplug. Said that it gave his SP-600JX1 another
9dB S+N/N, dropping the noise floor to about equivelent to the R-390A,
and he liked the broader slope of the filters. Gave it more of an R-390
sound.
