[Elecraft] East Coast USA Signal Levels

I've had an interesting E-mail discussion about European versus US 
shortwave broadcast signal levels on the 40 meter band.

To help put some numbers into the discussion, earlier this week, I took 
a couple spectrum analyzer measurements of the 40 meter band (actually 
6.5 - 7.5 MHz) and 0 - 20 MHz. I've posted the screen captures at 
http://www.cliftonlaboratories.com/Updates.htm, along with a brief 
discussion.

These numbers may help you associate the K2's dynamic range and 3rd 
order receive IMD specifications with typical signal levels. (Remember, 
it's not just signals on the ham bands; it's signals within the 
receiver's front end bandwidth that must be considered.)

Of course, antennas, propagation and other considerations determine 
signal levels, so I offer this data as only one set of measurements and 
would be interested in seeing others.
