WWV/WWVH Survey

As a ham we've all at some point heard and used WWV and WWVH for setting our clocks, guessing propagation, and getting solar info. There are even non-hams that use WWV without realizing it. They may have a self-setting clock that will listed for the time signal at least once a day and set their clock. And chances are your computer goes out to the NIST website and auto-set's your clock (if you're on XP and above, or OS X).

Right now they're conducting a survey online that might be beneficial to all of us hams out there.

Help make WWV and WWVH a little better by filling out the survey today!

40m long delay radio echo reported

Saw this on Spaceweather.com:

It's not uncommon for hams to hear themselves a second or two after they transmit on HF as their signal propagates around the world and then comes back on the "backside" of their antenna. It's even been reported that hams have heard their own voice come back 2, even 3 times.

But one ham in Germany recorded hearing his own CW transmissions an astonishing 46 seconds after sending them!

Peter Brogl, DK6NP, experienced this rare and little-known phenomenon (known as long-delay echo, or "LDE") on Nov. 27 on 7 MHz and managed to record the echoes.

The reasons for LDE's are unknown, although many theories exist as to their cause.
