picket fencing
(Repeater Term) A condition experienced on VHF and above where a signal rapidly fluctuates in amplitude causing a sound akin to rubbing a stick on a picket fence. If a repeater user's signal isn't strong enough to maintain solid access to the machine's input (such as when operating from a vehicle passing beneath underpasses or through hilly terrain), the signal would be hard to copy because of a pronounced, rapid fluttery or choppy characteristic.

whitewater rafting
A fun activity where you put on PFDs (layman; "life jacket"), jump in a rubber raft with little PVC paddles and float down the river....no big deal...until you get flipped over, hit on the head with a rock, hit in the teeth with a paddle, flipped out of the raft, pushed out of the raft, or are simply scared out of your mind and go into fight-or-flight mode with those class 5 rapids coming around the bend.
I was having a fun time whitewater rafting until we hit this class 4 sideways, our raft flipped over, I got sucked into the rapid and popped out about 40 feet away (still holding on to my paddle)...After whitewater rafting (which was a real rush) driving on the beltway doesn't seem so bad.

radio term
ha ha (laughter)
"hi hi" is the Morse equivalent of a laugh as in Morse it sounds like someone chuckling ("hehhehhehheh hehheh"). That is ditditditdit dit dit --- or dot dot dot dot dot dot. You really have to listen to it sent in Morse to appreciate its laugh like sound. It is most commonly used in CW (Morse Code), but has carried over to voice as well. Many CW expressions have carried over to voice -- such as 73 (Best Regards) and 88 (love and Kisses), etc. The origin probably dates back before radio to the telegraph days. And since Hams used Morse long before voice became practical-- the sound of the Morse characters HI HI was used to resemble a laugh sound. In some sense it is equivalent of a smiley. It's onomatopoeic -- that is the naming of a thing or action by a vocal imitation of the sound associated with it (as buzz, hiss) The definitive answer might be found in the "Dodge's The Telegraph Instructor Manual" circa 1850 to 1900. However, I have never been able to find a copy of this document. Wish I could as it would help to see the transitions from telegraph to radio usage.

radio
1) A form of wireless communications in which the output of the transmitter takes the form of dissipating electromagnetic radiation which spreads outward from the antenna through free space. The signal strength drops off as the square of the distance from the source of radiation. Distant radio receivers have to be very sensitive to detect signals that can measure only a few microvolts per meter in strength.
2) A communications device allowing the wireless transmission through space of audible signals encoded in electromagnetic waves in the approximate frequency range from 10 kilohertz to 300,000 megahertz.
3) (maratime definition) An instrument that uses electromagnetic waves to communicate with other vessels. VHF radios are common for marine use, but are limited in range. HF-SSB (single sideband) radios have longer ranges.
4) an electronic receiver that detects and demodulates and amplifies transmitted signals
5) Radio is a system for the distribution of advertisement, chiefly brand advertisement for package-goods, and advertisement for recorded music sold by BigCos. To describe radio as a system for the diffusion of news, or of music, or as a technology, would be not only inaccurate but actually misleading. Radio is a creature of the advertising business, as its child, TV. television
6) Transmit messages via radio waves, usally on a set wavelength, or frequency.

pirate radio
Pirate radio stations are usally one or two-person operations airing home-brew entertainment and/or iconoclastic viewpoints. In order to avoid detection by the authorites (The Man, FCC, etc), they tend to appear irregularly, with little concern for the niceties of conventional program scheduling. Most are found in Europe chiefly on weekends and major holidays, and mainly during the evenings in North America, often just above 6200.0 kHz, just below 7000.0 kHz (6955 and 6995 kHz are common pirate frequencies) and just above 7345 kHz. These sub rosa stations and thier addresses are subject to unusally abrupt change or termination, as well as their frequency of transmission, to avoid being cought by the FCC.
Free Radio stations are unlicensed broadcasters. They operate in defiance of FCC rules, which often seem to be more concerned with protecting the big broadcasting interests.
