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.
