[R-390] Nuvistaplug?

[Mark Huss]

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.
