(radio slang)
An amplifier used after the transceiver output. So named for its purity of amplification. Linear, in the mathematical sense, means that what comes out is directly proportional to what goes in. As far as linear amps go, if you double the input, the output is doubled and so on. This does not generate any additional frequency byproducts. If the amp is nonlinear, sums, differences and all combinations of those are generated also.

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.

Get the hi hi mug.A phenomenon on FM transmissions where the incoming signal is sufficient to engage the receiver limiters - thus eliminating the noise due to amplitude fluctuations.

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.
