[Spooks] Korean Traffic

Thanks Ary and Token,

I probably should've mentioned that I'm in Alaska and that's probably 
contributing to my difficulty receiving much from the Korean penninsula, 
given their respective transmit azimuths and power.

>From my brief lurking here as well as my other poking around, it sounds as 
if I would greatly benefit from throwing away my Grundig Satellit 750 and 
getting a good Software Defined Radio.  It sounds like the ability to 
record a given timeslice of bandwidth for later exploration is extremely 
useful.  Any SDR recommendations would be greatly appreciated.

For what it's worth I would love to hear recommendations for anything 
FreeBSD/Linux related.  I've seen a couple of FreeBSD packages that decode 
RTTY/PSK*/MFSK* and other digital modes, and I'm curious if anyone here 
has had any experience with them.  I've heard a few polytone transmissions 
and wonder if they're numbers stations, but I'm guessing it's probably 
nothing more than the dry cleaning request of a senior naval officer 
somewhere.  I'd love to be able to see if it translates to 5fg or plain 
text.

Thanks,
Mike
