Erik has a Aaronia Spectran that he has displayed on the show. One instance was while in the helicopter when Cameron was wearing NVG while piloting.
On the Beyond Skinwalker Ranch show the *investigators* detected a 1710-1755 MHz signal which was AWS-1 uplink (probably from their own phones) that they declared AN UNKNOWN signal. Those guys have zero creditability with me as they have little to no knowledge of spectrum allocations in the US.
The UAP task force report lists EM emissions accompaning UAP sightings and the report lists the 1 to 3 GHZ range detected by ESM systems. I think this what got Travis interested in the 1.6 GHZ signal at SWR, for what it is worth.
