While listening today in the CW mode on 4075.3 at 0100z I heard a 40 minute transmission of random hand-sent dits and dashes, sometimes with a short CW letter, A, N, K. It sounded like a straight telegraph key was being used by someone who was just learning how to send Morse.
I was hoping it was someone tuning up a transmitter for a new pirate broadcast or beacon, but it stopped after 40 minutes.
My location is coastal Central California. Any guesses?
Thanks for reading.
