[SixClub] Birdies?

Mon, 23 Feb 2004 08:09:16 -0800 (PST)

Now that you mention that, I located a birdie in my
house. It was the FAX machine. It generates a clean
carrier. Anyway, in my house I only have the 6m
repeater receiver, controller, and UHF link. The
receiver is XTAL controlled, so it is highly inmune to
the interference. I first noted it with my HT (Icom
IC-T/8) when doing band scanning.
