I had a suspicion that the oscillator in my RD 1992 frequency counter might be out of whack (that's a technical term). I remembered seeing a video by W2AEW about using a SSB receiver to adjust an oscillator to match the 10MHz carrier of WWV. So I did that, and it did turn out to have been quite far off.
I thought it would be cool, though, to see the WWV carrier on a scope along with the oscillator output like in EEVBlog #457. With that idea in mind, I undertook to design and build a receiver (really just a filter and amplifier). It came out pretty well, so I thought I'd share a video about it.
I'd be curious to know if anyone else has done something like this. I seem to recall some kind of commercial product that had an oscillator disciplined by a radio signal, but I think it might have been WWVB, not WWV?
I think I've heard that over-the-air frequency transfer is less accurate at HF (WWV) than LF (WWVB). I'd love to know what the causes are, but a quick search didn't reveal a satisfactory answer.
It was just a quick one-off for this particular project, but I'd still be interested in feedback on the design.
I also welcome feedback about the video itself. I'm still a bit new to this style of video and working to improve my technique. Feedback helps.
