The List
What's the frequency, Kenneth?

That’s a Realistic (Radio Shack) PRO-43 handheld scanner. They came out in the early 1990s. Probably one of the best handheld scanners ever made. This one has many SIGINT hours on it, including a stint at the Black Mailbox in Nevada, 1997.
The list is a collection of common civilian aeronautical and unofficial military air-to-air frequencies. Good for late-nite listening.
Thanks — noted.
