One VOLMET I listened to was at 6.604 MHz so maybe it does LSB too. I
don't know if that's what that means or not.
It should receive both fine. But tour assumption it is LSB is wrong
however. Almost all (99.9% or more) of the utility stations use USB over
the entire shortwave bands. Only HAM's use LSB below 10MHz, and USB
above. Why this is so I dont know, customs I guess
it realttes I am told how the first ham rigs generated SSB and how
they multiplied to get on the uppe r hf bands today t surrvies for
tradtion
Next I'm going to add a long wire antenna a see what that does.
I live in an apartment so I can't run one outside but I've read that
you can run the wire around the upper edges of the rooms even going
around more than once.
Thanks again for all the help and ideas. The radio crowd seems like a
pretty helpful bunch.
Loop antenna's! If you dont have good ground, and dont have outside
space outside of the electrical noise field inside your house, loops are
pretty much the only thing left to use.

Long wires are named becuase they are long, usually too long for
appartments. You'll also need rpoper ground with a random wire. Loop
antenna's dont need ground (at least, this one). Also, magnetic loops
are less prone to pickup interefreence from your electrical equipment.
I use that loop, and experimenting with an active pickup loop on ti
right now (with very good results). A (dutch lng, use babelfish) online
article of the pickuploop is he (its not meant as a pickuploop, but
its working fine this way) http://www.radiocollectie.nl/Schema's.htm
I'd first make the passive loop. And if you like, built the active part
later if you feel like it.
