They should have some real radio engineer in the show to handle their RF equipment. What they present as radio signals in their spectrum analyzes and how they use other RF devices in the show are just BS. That astro physicians they have are too ignorant and gullible to participate in the show. It's probably the producers fault that instructs him to act like a fool and be excited over everything, even false signals and misinterpretad events. But it's an entertainment show and not a documentary that needs all facts to be true.
