Greetings Jamie! I love shortwave and listen to nothing via the
internet. There is something that has always been magical about radio
to me. To try to get dx the computer and monitor go off. Too much
interference. For casualy listening if it is a few feet away it is not
much of a problem.
I have the DX-390, same as yours except without the tape and a better
speaker. I find it a very exceptable portable radio. It however will
overload with most antennas. Some of the guys in here can tell you
where to find info on how to run a good outdoor antenna for not much
money and cut back on the adjacent freq overload problem.
I have never had a remote for a table top. I am generally up in the
radio anyway when I am listening so why bother with a remote unless you
are listening to a strong broadcast in a casual manner.
My DX-390 is not very good at Medium Wave either. I have a much less
expensive DX- 396 which beats the pants off of the 390, and pulls in
stations a little better than my GE Super Radio II.
I don't think that shortwave is going anywhere soon. As with all
technologies there will be change and some inevitalbly fall by the
wayside. Time will tell, but IMHO not for the next few decades for
shortwave.
Any kind of radio placed beside a running computer is not a good thing.
Just too much RF. The monitor is usually the worst offender. Also
watch for floresent tube lights. Took me awhile to figure that one
out.
Hope that helps. Have a great week! Jon in S.C.
