[RFI] New Unidentified Noise

[Tony]

All:

Noticed a new wide-band noise that seems to span from 12 MHz to 50 Mhz. 
The rapid pulse sounds sounds similar to car ignition RFI and appears to 
have a square wave pattern. I receded a video of the noise using an SDR 
Dongle and was wondering if someone might recognize it.

The noise is coming from one direction and the device creating the noise 
seems to have ham-band filtering to some degree i.e., there's a lot more 
noise out of band than in-band on HF. It's a different matter on VHF 
though: it's pretty strong in-band on 50 MHz.

Any help would be appreciated.
