Harris can manufacture this under the guise it’s never intended for use within the U.S. They can claim it is for counter-insurgency surveillance in certain central Asian countries.

Alternatively, they could seek FCC OET authorization for the product as test equipment, but I doubt it, and my quick searches have yielded nothing.

I suspect this is why Harris, FBI and other LEAs conceal their use [1].
