I found two Morse code beacons within a few kilohertz of each other. A "D" beacon at 13527.50 kHz and an "S" beacon at 13528 kHz. Recorded May 15, 2020 at 1437 UTC via the UTwente WebSDR. I know very little about letter beacons. Are these two well-known?

Both the beacons you reference are mentioned in this Wikipedia entry, and are referred to as cluster beacons -

Nice research, thanks. I figured that both of them had likely been around for awhile, but since I don't really follow letter beacons as much as I do other signals, I wasn't sure.
