Listening to HM01 on 10.715 Mhz. Not a big catch, being that I'm in Florida, but I noticed it was 4 mins early today, but it was a few mins late on Friday 1/14

Very good reception up north.

2213 cinco ocho dos tres
2215 Off, pause?

2235 YL back to reciting numbers in Spanish, unsure what time it restarted

HM01's standard procedure is 20 minutes of numbers and digital mode, 10 minutes off, 20 minutes of numbers and digital mode, then off. If there's another broadcast scheduled for the next hour and everything is operating the way it's supposed to, the carrier will come up on the new frequency pretty quickly after it's QRT on the old one. Anyway, that's kind of a long way of explaining that if it was silent at 2215, it must have come back on at 2225.

You're welcome. A few other things of note...

It's being run on an old Windows machine that's most likely isn't connected to the internet. It's supposed to be on at the top of the hour but the clock runs fast and progressively starts earlier and earlier until someone finally decides to manually reset it. I'm not joking when I say this, I think that happens maybe once every couple of years.

Also, and this has also been true for several years now, it will simply broadcast the same thing day in and day out for months on end, and at some time suddenly debut an entirely new set, maybe progress normally for a few days, then get stuck again for weeks or months. It used to be that the final digit of each number group went up by one each day, and once it hit about seven (sometimes lower, sometimes it would go to eight or nine) then that particular number group and associated file would be changed. However it is often stuck on numbers that don't progress and files that don't change for months. I personally observed that today's batch is exactly the same as I first observed in November, and have seen reports stating that there hasn't been a change since sometime in September. I really don't know what on earth they're doing, or if they even know what they're doing anymore.
