Speak for yourself.

For me, the biggest problem with shortwave is manmade noise. And has
been for about the past 20 years or so I've been living in big cities.
Being able to hear anything more than the half-dozen or dozen
strongest signals means getting out of town.

I'll be damned if I have to take a computer with me camping (and then
bother with shielding it so I don't have to hear the sort of RF crud I
just drove out of the city to get away from) as well as a radio set.
Oh, and then there's the extra power consumption (remember, I'm using
batteries out in the woods) of a computer just because a radio doesn't
have a front panel anymore. Plus, I can't see having to fiddle with a
mouse pointer on a picture of a tuning knob as any sort of improvement
of having a real tuning knob to turn.

Receivers having a single conversion have the lowest internally
generated noise ,I believe. It may be possible to have SDR with better
performance,eventually one day. Actually,any receiver having an
oscillator generates birdies. A PC or a laptop generate more RF than
the Woodpecker transmissions from years ago.
