[R-390] What is the difference between 390 and 390A

[Flowertime01 at wmconnect.com]

I have heard that the 390A was better than the 390 for BCB DX'ing because of 
the mechanical filters. I mostly DX for foreign DX on the BCB frequencies 
and most are very weak against very strong domestic stations sometimes 1 khz 
away. Will the mech. filters perform better for this purpose? I can put up 
with lousy ringing audio if I have to to to hear a station that would 
otherwise be obliterated by QRM from a 50KW local 2 kHz away. Actually my 
motto is you can never have enough radios anyway,

Bob,

Most 05H guys liked the R390/A over the R390 when it was time to pick one out 
of the mud. The 2Hkz mechanical filter will let you get a bit more separation.

On any day given any two adjacent signals one wanted one not, Its going to be 
a subjective opinion what one receiver works best. I watched 5 or 6 ops roll 
up on a ditty with two radios each and all the Opts said every R390/A of the 
10 or 12 sounded different. They would send the worst receiver to the shop for 
PM. But their choice was still the R39/A over the R390 to pick crude from mud.
