[Elecraft] A little OT...odd noises on 40M

[John Wiener]

For the last couple of nights, at about 7022 kHz there is a most  
annoying noise that appears not to be random.  If this is a digital  
mode, what on earth is it?
It's about 3 kHz wide and has a high and low register, both are  
"gravelly" and seem to be fairly broad spectrum audio.
God, it's annoying!

As a newbie, I don't know for sure the sounds of various digital modes.

BTW, I now have CocoaModem.  Where can I find specific information to  
get my K2 into digital mode.  I find CocoaModem rather  
undecipherable...no manual to it's use to be found.  My apologies if  
this is a repeat of earlier threads.
