Very sorry but I don't understand this. As far as I know, the output at the earphone jack is analog, not digital.

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.

But the digital effect disappears when using my wife's wired landline phone (which I'm sure turns into VOIP along the network).

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!
