RF copied audibly but with fast QSB into EM68es - South Eastern Illinois.  The Argo capture has the exact details.

22 Meter Band HiFER Beacons / Hifer beacons RY and EH
« on: December 02, 2017, 1723 UTC »
I shut down the WM Hifer beacon to do some listening this morning on it's antenna. So far I have solid copies on RY and EH which can be seen in the ARGO capture on Dropbox; https://www.dropbox.com/s/521pk9u5k5jxt6m/dec020001.jpg?dl=0

I saw NC briefly but don't have a capture on it yet.  It's kinda weird in that I am using a new KiwiSDR on the beacon antenna and it hears RY and EH just fine. I have my Kenwood on a trap vertical and it only hears NC and EH.   Some kind of magic I guess.

Hello my name is Mike, and while I have been a reader here for a while, this is my first post. I have been a SWL since the 60's, so have heard many different things over the years. However this is a new type of transmission for me.

While having the radio set to capture “hi-Fer” beacons using Argo running on the pc I heard sounds of what I would describe as human whistles. There is a variation in the whistles, but seem to be repeated in patterns, suggesting some type on information is being passed. I have heard this off and on over the past couple months. The signals are weak, generally not budging the s-meter, and had been received in the daylight hours only.

I have searched the forums here, as well as google and other internet places without finding additional information. I hope the group can provide some additional insite.

You can listen to a recording of 13.554 USB,  made on 03/25/2014 at 14:00 utc here


Thanks for reading.   73  de N8OOU Mike
