[Elecraft] K3 Dual Receive Surprise

 > Pretty sure it's The Weird Stuff Out There.

I have a page dedicated to all kinds of weird stuff in terms of 
propagation, see http://www.qslnet.de/member/la3za/prop/

The page has a collection of audio samples from unusual HF propagation 
phenomena, from round-the-world propagation (delay 138 ms) to 
moonbounced signals (delay 2.39 sec), and to ducted transmission (delay 
~140-300 ms).

On 160 m and 80 m, one kind of weird delayed propagation is the ducted 
one, where signals travel along magnetic field lines into space and 
back, but it is very rare. I wrote a small article about that which will 
appear in the March 2009 QST Technical Column.
