Listening (2023-08-26 0019 UTC) to an odd signal on 138.82 kHz that I’ve heard several times before. Repeats endlessly in 10 second cycles: 9 seconds of carrier with 10th second being some kind of data. Seems synchronized with UTC in that the data seconds occur precisely at seconds 01, 11, 21, 31, 41, and 51 in every 1 minute cycle. Has anyone else heard this? Any idea what it is? Bruce WA1HGJ
