from day 1 I suspected microwave radiation. my theory was that it was microwave excitation of a passive bug, something like the infamous bug the Soviets planted in the Great Seal.

but this is also from a state-run propaganda outlet, so who knows.
it is interesting to think about a microwave pulse generator with a focused high gain antenna. short pulses could be hard to detect with a traditional spectrum analyzer, particularly if the frequency jumps around
@tubetime even a big dish antenna has enough sidelobes such that detection of high power pulse transmitters is easy.
