MHz

Pronunciated: "Megahertz" not "M.H.Z."

Megahertz means 1000 kilohertz (kHz) and kilohertz means 1000 Hz (cycles per second)

1 MHz = 1000 kHz = 1,000,000 Hz

Wow, sense I listen to DC101, who has a transmitter on 101.1 MHz, thats 101,100 kHz, which is 101,100,000 Hz (cycles per second)

oscilloscope

A test instrument that shows a picture of electrical waveforms by means of a cathode ray tube. An oscilloscope is calibrated so one can measure the instantaneous values and waveforms of electrical signals that are changing rapidly or varying as a function of voltage or time. Also known as a Scope.

I use my oscilloscope to measure the waveforms of my 27 MHz band jamming transmitter.

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.

There are many differant types of radio-frequency modulation, these include AM and FM.

gigaflop

A billion, i.e. , 10(9), floating point operations per second.

Only supercomputers can run that fast..idiot

SOS

SOS really doesn't stand for anything, as any radio operator will tell you,

it is simply "SOS" becuase the letters S and O are very easy to understand under conditions of high interferance.

so stop saying "Save our whatever"

SOS, SOS, Titanic
