Title: UNID signal 6946 kHz USB 0000z 8/11/2017
Post by: MaxwellHouse on August 11, 2017, 1836 UTC

I received this signal starting 0000z 8/11/2017 in Dayton, OH. Signal was present for several hours, in fact I heard it going two hours later.

Received on a County Comm GP-5 SSB, so when I changed the tuned frequency or BFO I noticed a change in tone. The attached spectrum shows the audio I received when tuned to 6946 kHz.

Signal sounded like a drum at first and so I thought it might be a pirate station, but this was all I heard over the several hours. (spectrum and audio https://youtu.be/pU2ZwallFRE (https://youtu.be/pU2ZwallFRE))

Thanks!

This is Link-11. It shows up here from time to time. Presumably the US military.

Thank you!
