Ive been copying this signal for about 4 months or so. https://i.imgur.com/76RhnWw.jpeg
It's on a 20 minute interval and drifts a bit in time, as if the RTC on whatever is sending it shifts a bit. As you can see, it's sometimes quite strong.
I am in central NC and this is being copied with an attic 20/30M dipole @35'. Anyone else able to hear/see it?
