... I can still barely get WWV, but back when I was living with my parents and listening on shortwave in the early 80s on a 1934 RCA “Globe Trotter” console radio, WWV was always reliable and sometimes when I got good skip, I could hear WWV and WWVH at the same time!
If you felt like an enhancement to your site, that would be my request… play both audio tracks together.
I came here to suggest this 'feature'. Maybe you could offer a slider that can mix the two 'stations' together to simulate what it sounds like in some areas (such as here in the Pacific Northwest of the US).
