23:07z I've been monitoring 6739 USB for 15 min and I'm hearing a beacon...*beep*...*beep*...very slow but not completely consistent. The beeps are longer, or shorter...it can't be Morse...do u think we'll hear sum HFGCS on 6739U tonight?
Is this beeping/beaconing for some other purpose, that you know of?
▲23:11z and it has stopped...and started up again 23:12...weird beeping. It is erratic with stilted rhythm
▲23:28z still going. I'm gonna sit tight
▲1:22z I've been checking this every few minutes. I do not hear it anymore. I do not copy a thing.
Do they do this beaconing to test propagation conditions? All quiet now
