Signals for 0500-1000 UTC were all uniformly weak, and in fact there was no transmission in the 1000 hour at all, nor were any signals found for the remainder of the day at their presumed times and frequencies. So while I was able to hear the numbers, no digital files were decoded.

This is a three day progression from Friday 22 MAR, so either yesterday saw a two day leap (which I don't know since I copied nothing at all that day) or today did.

This is a two-day progression from yesterday.

Technical note: Because of the late (or early) hours of the 0500-1000 UTC transmission, I program my SDR to record each of them in order to ensure that all number sets and files can be copied over the time frame. This is often in doubt because of Cuba's well known technical issues regarding their shortwave transmissions, and in fact it was only a few days prior that I couldn't pull out a single file because the signal was poor. Obviously propagation is a factor, but so is the unreliability of Cuba in which scheduled broadcasts don't happen when they're supposed to, starting late, finishing early, not changing frequencies at expected times, etc. I've only been casually following HM01's scheduled daytime transmissions (1600-1800 and 2100-2200z) ever since they switched their "new day" from 1600z to 0500z, but there have been days were no broadcasts on any of their frequencies at those times.

However, today all six frequencies were very strong (the one on 9330 overwhelming WBCQ's flamethrower almost completely) and timely. It was as if everything*, whatever was wrong, is now fixed. It still starts a few minutes ahead of the hour (about 5 minutes) but otherwise they were about as reliable as you'd expect Russia's numbers stations to be. I'm going to see if that holds for their daytime broadcasts.

*almost everything. As noted, today's number sets advanced by two rather than one.

This is an exact repeat of yesterday's numbers, which had been a two-day progression compared to the previous day. Let's hope that this is just a schedule correction and not the first of possibly hundreds of repeat days, as has plagued HM01 in recent years.

51071 - 02575107.txt
75441 - 05647544.txt

The one old number group shows a progression of +6 from those sent 0500-1000 UTC. I did not check out the 1600-1800 UTC transmissions because they were too weak to even hear the Cuban lady.
