About ten years ago, when I was living in Seattle, I had a clock radio
with rather crap reception, so finding a station I was both
interested in and capable of listening to when I woke up was a bit of
a task. One day, though, as I began slowly and carefully tuning the
dial to try to find something worth listening to, I stumbled across
clear, strong, and repeating Morse code. It wasn't an SOS, which was
about the only Morse I knew, but it was a good strong signal, better
than the alarm clock's built in buzzer, so I shrugged mentally and
left the tuner there. As a result, the pattern got burnt into my
brain.

Some years later, I decided to look up what this dot and dash pattern
might mean, in hopes of determining what I'd been listening to. I'd
heard of CQ, so I thought it might turn out to be that, but no...

That's 'BF', isn't it? Why would someone be sending 'BF BF BF' out on
a radio frequency? Or was my radio so crap as to be picking up
something else entirely? Please shed some light my way; I'm feeling
lost...


My guess is, you may have been picking up an NDB (Non-Directional
Beacon), used by aviation. Perhaps you were close enough that it picked
it up, or perhaps you had tuned to the second harmonic of the signal, or
there were some unintentional signal mixing products in the receiver
that allowed you to hear it. Hard to say. But that would be my guess.
