They're more resilient than you may think ;) I think that one died as the result of 4kW being applied to it...Quote:

About QRO in a Part 15 environment, an anonymous former (but then) CB'er was sitting in a line at the Fast Food Drive-thru and it was taking forever -- with full knowledge of his transmitting capabilities, the unnamed former CB'er keyed down his QRO appliance and said,Quote:

That is damn funny! In Kevin Mitnick's book, Ghost in the Wires, he was talking about a time he would overwhelm the drive through speaker and acted like he was taking there order. A few times he would tell women that pulled up that certain parts of their body were.. ahem.. undesirable. Hilarity ensues.Quote:

When they got there, they noticed their drinks were ready ahead of time.

I had a friend back in tech school who had a "kicker" in his car along with his CB and his favorite past-time was pulling up next to people with their stereos cranked and yell something over the radio.
Usually it was "turn that S**T down" or something like that.
It was pretty comical to see the people in the car looking around trying to figure out where it came from.
He was the only guy I knew that embraced both hobbies well. On CB...he was a clown. On HR...you'd never know he was on CB.
He was truly radio bipolar.

The problem is as I said, they're TOO resilient so even if they don't pop overshoot causes distortion. If a speaker can't track the waveform it's a POS.

Cabin gain? Before we go any further I strongly urge you to learn about acoustics, wavelength, enclosure design, etc. and be more of an audiophile than an audiophool, OK?

He could have had a LOT more fun if he programs the frequencies fast food joints use for their headsets in his VHF/UHF transceiver, the ones that communicate with the drive through are particularly interesting.
"...he passed out order pads and ink pens to his staff."
It can't be McDouchebag's or Booger Fling, pimple puss can't add 2 and 2 and can't make change by counting up from price to cash tended. That's why they have little pictures on the register keys and a computerized order system.

Kevin is more of a genius than I am, I turned my electronics hobby into a career, he turned his into a very profitable systems security business. Actually he overwhelmed the drive through frequency with more power than pimple puss' headset as described above. Pranking them is, eh, fairly common and done from a discreet distance in the parking lot, 5W easily overpowers a 100mW Part 15 device.

He was until I showed up.
"On CB...he was a clown."
Besides an avid experimenter I was a clown, a prankster, a mystery reciting beat poetry, the most interesting man in the world, and I got laid a lot.
"On HR...you'd never know he was on CB."
On the air I never mentioned CB, the subject never came up. The only reason you know is because I like to talk about the great times I had, I'm the most interesting man in the world. Stay thirsty my friends, Dos Equis sucks, drink Yuengling.
Here are a couple of classics, those free Kevin stickers showed up in the darnedest places. Make that four classics, three friends, phone phreaks (in my phreaking days I spoke toll free with Crunch and Woz) turned hackers, gone legit, John Draper aka Captain Crunch, Kevin Mitnick handle unknown, and Steve Wozniak aka Woz. Steve Jobs too was a phreaker/hacker too, see where hobbies can get you when you play your cards right?

Very true. Although in the last ten years, there's been a lot of work done with motor designs that optimize the BL curve for a particular app.

CB is very important to me. More important than HR. I am seriously considering getting back into CB in a big way. I want to run at least 5 to 10 Megawatts of power. I don;t know how many pills will be needed for that amount of power that but I do know they are gonna have to be very potent pills.
Lemmons! :shifty:Quote:
