I caught
this beacon sounding off at around 3:30 am local time (0830 UTC).
It's on 5058.5 kHz. It's slowly sending this in Morse code: “WI2XJP WAYLAND MA FN42HI”
WI2XJP appears to be a license for an
experimental station in Wayland, Mass. FN42hi is the grid square.
I'm afraid the FCC experimental license information doesn't really tell us much. It's authorized on a variety frequencies, in a variety of modes, at 2 kW ERP. Has anyone heard this, or know what the purpose of these broadcasts are?
