3.901 mhz LSB beacon
« on: April 30, 2026, 0419 UTC »
4/30/26 @ 0400 UTC. 3.901 mhz. LSB. A single beep approximately every 8 Seconds. S9 in the Mojave Desert. Seems to have stopped by 0415.
Hams on 3900 have heard it recently as well, so it's ongoing.

5/12/26 @ 505 UTC. I'm getting that Beacon again. I believe it's actually on 3901 kilohertz CW. It sounds like a heart monitor in the hospital.
