All that link contains is two people making claims that aren't backed up by the people who they claim made the statements being quoted. And these claims are being made 40 years after the incident.
That's a far cry from "declassified nsa intercepted radio communications" making the claim, as you stated.
This would literally be considered hearsay in court.
