“Mystery Signal” is alive and well

Some of you have been asking if the “Mystery Signal” is still on the air. Yes it is! Here is a recent clip of it mixed with some CODAR. I’m also trying out SDRUNO software for the very first time. Recorded on May 24, 2017 around 0445 UTC using my SDR PLAY RSP1 attached to my OCF dipole at 35′.
