[R-390] R-390A Operation Question

[thoyer]

 Never having operated an R-390A before, I am questioning the amount of
"hissing" I get when on the 16 and 8kc bandwidth settings.

Below is a link to a video (hope it works) that shows what I'm talking about
(Copy and paste the link into your browser then click on the picture to load

The file is a .MOV file (iPhone) and 89mb so it may take a minute to
download.

Also, seems like when I have the BFO on and the RF gain at max, the signals
are somewhat distorted. If I back off the RF gain a bit the audio sounds
much better.

I have worked through each stage, replacing the out of spec parts and
aligned it per the book. The IF gain has been set per Chuck Ripples
recommendation.

Overall the radio is functioning well, just this hissing is a bit annoying
and making me think I'm not quite done working on this radio...........
