Signal clean enough for the ID layer. But so is WRMI, creating a problem for the digital signal. TDF left at 2358, and WRMI was all 4's.

The RTTY portion from yesterday clearly starts at 52 seconds, lasts for 2 seconds, then there are 5 time pips of 1kHz bursts just prior to the minute marker, which is obviously obliterated by WWV.

Apparently the station underneath also transmits CW during 0', 15', 30' and 45' as heard in this clip. The sequence starts at around 15 seconds in and lasts for around 20 seconds. Unfortunately, I'm not very proficient in Morse unless there's a lot of repetition (e.g., NDBs). Portions almost sound like 'CQ de' and an ID, but I can't be sure with all the interference.

Maybe someone with younger ears (that haven't been blown out and ringing from 100dB+ of GnR on repeat) can make out what they're saying.

Managed to capture what u/Ancient_Grass_5121 previously reported regarding the RTTY burst on WWV. It starts just as the announcement begins, and ends shortly thereafter. I've also narrowed the sample rate on my Airspy HF+ to 192kHz so you could see it better.

For reference, this has been noted on HF Underground before: https://www.hfunderground.com/board/index.php?topic=10959.0

Part of the 'Plus' part of this sub - nice article on Es, that's more prevalent during the warmer months.
