You are much more than "Decently Attractive". Very pretty, don't sell your self short. Saying this as a white male.

The frequency does not have to be outside of the FCC limts for this to happen. It's simply poor Radio Frequency (RF) shielding in either the cables or device itself. I'm a ham radio operator and we deal with RF interference all the time using totally legal frequencies. In fact RF interference is why many well designed devices will have a cylindrical object in the connecting and / or power cords. That device is a ferrite choke and it's purpose is to minimize the induced current that results from nearby RF fields from affecting the device.

I don't know. But I've been a Ham since I was a kid in 1982 and I know many hams that were licensed in the early 60's. I've always heard it was someone's "fist" that was unique. However most operators since the early 80's use what is known as a "keyer" and a set of paddles. One paddle make the dit (dot) and the other makes the Dah (dash). The keyer makes perfect spacing for each letter and therefore makes you sound less unique but better and easier to copy. Also using an electronic keyer allows you to send much faster (>60wpm in some cases) than a straight key like you see in old movies.

It's called the "fist" not the hand. Source I still use Morse Code as a Ham Radio Operator.
