As far as I know, The SG has two audio outputs, the headphone jack on the
front and the remote speaker jack on the back. There are those two RCA jacks
on the back, don't know what they're for yet, but I think I read somewhere
that the one nearest the edge is a receiving antenna.

from my ST590. It's just a digital sound, and my cochlear implants (being
digital devices themselves) just don't handle digitally-generated sound
well. I'm seriously thinking of finding an old ham receiver with analog
signal processing and putting up with poor selectivity etc.

To a lesser extent, my land line phone, which is actually VOIP through
Comcast, also sounds digital. But the digital effect disappears when using
my wife's wired landline phone (which I'm sure turns into VOIP along the
network).

blanker turned off and listening to AM broadcast stations with broadest
selectivity. But my Victor Stream (which is actually digital), sounds more
analog and better. In the 590, I can turn the RF gain down to keep an SSB
signal from influencing the AGC, and this removes the digital effect
somewhat. But I think something got lost in the audio quality (for my ears
at least) of modern transceivers. Maybe I'll try building my own receiver,
like the regenerative receiver I built in my novice days. That used vacuum
tubes and was inspired from an article in the BTP. It wasn't much, but it
was analog!
