Seen this 1st on HFU, then SWL'ing. So, here's my $0.02 worth:
I was so glad to see this 25MHz side come back to WWV. Not only is it a great propagational beacon for F2 and Sporadic E, but I have, and will still, use it to retune radios' master oscillators too. My Kenwood TS-2000X was a rig that came out of the factory with a slightly mistuned master oscillator. (Enough so that you would notice it on 2M SSB, 432MHz SSB, and especially 1296MHz.) By zero beating the 25MHz in CW, then testing in LSB and USB, I was way more on FREQ with that rig. Tested that against an Icom IC-745, where the manual actually tells about the WVV / master oscillator tune-up procedure. Next, I plan to retune a Kenwood TS-50S rig that I know is about -50Hz off FREQ. It's enough so that I notice that on 10M SSB. Like I said, a very useful, rock solid, 25MHz signal source, just too bad that I can't RX it every day.
Oh yeah, here's the link, [
