Beacon? 3.900.15

[Claim Jumper]

Is this a beacon? 0512 utc. 4/17/24.
Thump thump. Heartbeat sound. Clearest on CW at 3900.15.

I can hear it on Lower Side Band as well. In fact it's pretty wide. All around 3,900

It stopped sometime just before 0600 UTC

It’s hard to say what you heard but see if it comes back in the same time frame. Quite a few beacons operate nighttime only.

Also look at our listing of known beacons in the pinned topic of active beacons.

Thanks. I will record it next time. Is there a way to attach a recording? That would be a great feature here.

Tonight around 0730utc I heard the same signal on 3900.  At the same time it is also on 3550 and 7050.  I also heard it several times a year ago.  It is typically on for an hour or thereabouts.   I have no idea what the source is.  Checking on SDRs in California, Utah, New York and Alaska, I heard the 7050 signal on all of them, with the Utah SDR having the strongest signal. 

Here's a link to a previous posting of mine about it:

one way to share is to post to YouTube. Forum member Token has excellent recordings from his SDR  at  https://youtu.be/LvxhB-xhSJE?si=5hQoR2CPPNbESHfi

Nine years back I posted some very simple videos where I posted a video of my receiver or combined the MP3 audio clip with some photos

Thanks for the info longwire. I knew somebody out here must have heard it before. A gentleman I was speaking to on 3900 Lower Side Band noticed it and told me he had heard it off and on over the years.
Also thanks for the reply teotwaki I will start looking at posting recordings on YouTube.
