The A beacon has been quite elusive of late. I am catching a glimpse of it with a very weak signal audible now and then this evening. Was doubting myself as to if I am really hearing it but it just faded up a bit and was for sure there audibly and visible in the waterfall for about three passes before fading out again. 2097.29 KHz 31DEC23 05:27z Airspy HF+ Discovery 60ft SE/NW longwire
I've had the same issue, I just figured it was the propagation from getting closer to maximum but I'm still getting other signals on similar frequency range pretty much the same. When I was hearing it it was usually in the evening when that part of the band started to open up as the sunset but then as it grew deeper into the night the signal would get lower.
Wonder if it switched to solar power or something then the battery died and won't hold charge anymore.
