WWV's 25MHz signal?
« on: March 05, 2024, 1825 UTC »
Just, out of my curiosity, how well, and how far, can y'all hear WWV's 25.00000MHz signal in the day hours? It, is just out of reach for me to hear it when Sporadic E PROP is active, from my QTH. I'm really glad to hear it, and even use it, again with Cycle 25 bringing F2 PROP back. However, I have to believe that it's signal is being heard on the other side of the world.  https://www.arrl.org/news/wwv-25-mhz-signal-swapped-to-circular-polarization 
I was asked, yet another weird question, of how I would like to be buried, when I finally bite the big one. The answer was actually pretty easy. Face-down, like a certain historical figure in the late 1980's, (I will not mention who, but some of you will get it, and that's enough.) Why??? It would be a burial that will satisfy everyone: (1) My enemies will say that it will show me where to go. (2) On the same point, I can have my enemies kiss my butt. (3) It will temporarily give someone a place to park a bicycle. See??? A WIN / WIN for everyone.

On a good day - clear across the world.

10 MHZ at night you can hear both the WWV signal and the KHWWV signal from Hawaii - the Hawaii signal is faster than the Colorado signal - so you hear the one before the other.

10/S-9 into N. OH as I type this.

For those who are hams, 12M is hopping at the moment.

And the 25.950 signal is S4 +/- but currently unmodulated.

I have never heard it here, sure its entirely possible if there is some short skip. I'm located 357 air miles from Ft. Collins, Colorado to my location, it's most likely I am sitting inside the skip zone.
