This has been bugging me for a while. For the last part of the last year and all of this year, we've received a constant stream of morse on 7.6 mHz, at most times of day. I'm going to assume the broadcast is constant, because it only fades, never just stops.
Googling reveals nothing that I've found, and I only have a noisy MacBook to record to. Might try it if I get desperate enough.
Mojave Desert, btw.
