Gray Line Propagation


Gary DeBock
 

Richard and Others,
 
      An excellent web site for checking current gray line propagation is http://dx.qsl.net/propagation/greyline.html. It has a map that refreshes every 5 minutes, and shows where sunset and sunrise are occurring in the world at any given moment.
 
     Of course, there are only certain times of the year that these gray line paths allow great propagation from TP or TA transmitters to North American DXers with Ultralight radios.  But if you are lucky enough to have a gray line path as well as good solar conditions, you can have a fantastic logging.  One of these occurred for me on August 28th, with a booming signal from VOA-1575 in Thailand on a stock DT-400W at Grayland, WA.

Gary,

Thank you very much for posting that link. That's handy dandy for
sure!! Somewhere in this unorganized filing cabinet I have that old
world map with overlays for each month showing the same thing as that
website. I think they called it the "DX Edge" if memory serves me
correctly.

Kirk,

You are correct! It was called the "DX Edge" and I still
use mine. I keep the white plastic world map "slider" and
the clear plastic overlays in a white over-sized postal
envelope in the front pocket of one of my DX notebooks.

It's amazing that the overlays haven't yellowed with age!!

Comes in handy when I'm too lazy to boot up the laptop!!

Gary:

I use the web site occasionally and you're correct it's an excellent
resource.

I also use a program called AZMAP v. 3.7. It's available from http://www.aa6z.com/. I've found it useful.

Good DX.
