Phantoms of the Airwaves

Through the years, I've encountered numerous unknown signals on the airwaves with both RTL and other receivers such as my SDR-4+. Hence, I've decided to dedicate a thread to those phantoms so they're all in one place. I've never bought the conventional explanation that most are artifacts since I use minimal gain on my receivers.

I start this thread with this unknown digital signal which was closely centered on 7180 kHz and occurred around 0340Z on Jun 27, 2017.

BTW, this signal had weakened considerably when I captured it. It was much better organized before the capture.

Another culprit at 0405Z on July 20th, 2017 @ ~ 7150 kHz... One day, I'll attempt to identify the type of signal.

I'd think the USCG might want to investigate further...

One day, I'll find the time to identify these digital signals.
