I am calling this one the Satan Signal. It was recorded yesterday but I have other longer and slightly different recordings from another day as well.Up to an hour in length. It is recorded in AM though I do switch to SSB from time to time. AM is the mode that seemed to reveal the most about the signal as it was a carrier signal that I could tune to either side of . This seems to be modulated somehow.
This signal was heard from 13 mhz to 15.5 mhz every 10kc simultaneously . First thing thing I thought was some sort of computer or appliance interference . If it is it is new to me !! It was very strong .
It mostly consists of short (10 second )(each being ever so slightly different than the other) signals but toward the end of what seemed like 10 minute intervals of short signals it would go into a long transmission that would start out slow just like the others but speed up to an incredible speed then stop completely. These long transmissions varied in length and sometimes seemed like they were halted because the signal could not develop the correct speed . Much like a turbine engine that refuses to flame on ,if you know what I mean .
Many decades of HF listening have not prepared me to describe this signal. I have NO idea what this is. It was peaking in a certain direction but I shall keep that direction to myself.
The recording seems to be a little glitchy I think that is Media Fire .
It starts out with 2 or 3 short transmissions ,then into a longer on that seems to flame out then a much longer one that seems to make it to full speed then off very suddenly.
