No. Radio waves come from satellites. You're probably thinking of  radiation waves, which do come from the sun.    2nd Answer:   Oh, my heavens, the Sun is a huge emitter of radio waves! In fact,  if an astronomer looks only at the Sun's radio waves, the Sun looks  somewhat larger than if...
Radio signals under 30 MHz (give or take) are reflected off the ionosphere back to Earth, whereas radio signals over 30 MHz (give or take) normally go straight through the ionosphere. The maximum usable frequency (MUF) is the highest frequency reflected by the layers in the ionosphere. This...
The government did not take up seriously the licensing and control of amateur and commercial radio operators- all this was in Code then, until about l00 years ago. There was something called the Roberts Bill. Popular electronics writer- and also a Science fiction man- Hugo Gernsback manufactured...
jawbreaker by the dead weather
 When you set up a  Uniden Bearcat BC148XLT base scanner, you must program the  frequencies you want to scan based on your area's frequencies. You  do not need to include weather frequencies, because the BC148XLT  includes weather frequencies pre-programmed in the base. You can  add...
I have the same one it is hard but try the hold button and messwith it more.
Full duplex is when two frequencies are used for stations to transmit to and receive transmissions from each other. A station will transmit on one frequency, while receiving on a different frequency. This is often accomplished through the use of repeater towers. Radiotelephones, cellular telephones,...
Well, the origin of Weegee is Mario Is Missing, when he had a sprite which had him in this odd position.
you do not need a license to purches a ham radio. you also can listen to chatter without a license. but if you want to talk you need a license.

Athletics and... *ahem* conquests.
This varies user to user, but for the best output, a low keying wattage with more forward swing is best. If you drive the amp with a keying wattage of 1 watt, and a forward swing of 20 watts, the amp will perform and the modulation will be loud and strong. Where if you key the amp with 20 watts and...
Net is short for network. It is a group of organized radio stations meeting on a set time/frequency to exchange information etc. For example, every night a 8:00 p.m. our club runs a net where individuals tune into a set radio frequency to allow for announcements, messages or emergency information to...

My suggestion is to take your voltmeter, measure the voltage between the center pin and shell of the cigarette lighter socket in the car, and note the polarity there. The shell is the grounded side of the lighter socket.
Many ocean going vessels operate on HF bands and use satellite radios, none of which are accessible by most scanners. There are standard VHF frequencies/channels used by many boaters and ships though, and you can follow the link below for a complete list of them: http://www.navcen.uscg.gov/marcomms...
CB radio uses a frequency of 27 MHz and 49 MHz band. A FCC permit is required but no Morse code or electronic knowledge is required. Ham radio is a FCC licensed area which requires various degrees of electronic knowledge and in some cases Morse code proficiency. CB radio (citizen band radio) is...

Ham radios are also called amateur radios. I  am going to recommend you two ham radios and these are one of the  best amateur radios in the market.  SR-955 HPC and SR-655 HPC are the best amateur  radios. Below are some of the feature of SR-955 and SR-655.  Have a high power radio, 7 color...
When two frequencies are "mixed" the sum and the difference frequencies are produced. These frequencies are called heterodynes. If these frequencies are outside the range of human hearing they are said to be supersonic. The full name of a superhet receiver is supersonic heterodyne. This receiver...
The length of a quarter wave for constructing one end of a dipole is:234/MHz = feet of wire.For instance if you have an 80 meter ham radio transceiver and want to construct a dipole to match a frequency of 3.56 MHz (the low power calling frequency) then234/3.56 = 65.7 feetNext buy a spool of speaker...
Depends on many factors. What frequency are you talking on, what are the atmospheric conditions like, how good is your antenna, are you sending code or trying to talk voice, how good is the other ham's receiver, etc. I can tell you that when I first received my license in the mail, my first contact...

Not necessarily. Normally, Ham Radio is used to describe amateur, 2 way radio where 2 individuals talk to each other back and forth; on the other hand, shortwave radio generally is used to describe commercial High Frequency radio broadcasting. This band is a commercial service that provides long...
There are no amateur radio shops in St Helens, OR. Closest would be Ham Radio Outlet just south of Portland.
One should program a Regency Scanner with the model number r1077 by first turning the device's power on. Then press the manual button until the channel wanted is shown. Once the channel number is shown hit enter, which will make the frequency channel that number. Then one can go to the next channel...
Once you have your Amateur License, you can buy a ham radio online, you can go to a local hamvention where vendors like icom and kenwood will be selling radios, you could go to a local radio club, I'm sure they'd be happy to sell you one of their old radios at a great price, or point you in the...
With radio on, press manual, enter the group you want the new freq to be on. 1-5. enter the channel, enter the freq by pressing the number keys, press enter. The desired freq should remain on that channel until changed. Press manual for the next channel to be progrqmmed.The 250 is the best scanner I...
The challenge is going to be packaging rather than technology. It is possible but most likely you will need to use a spray cooling system rather than touching the tube with a cold plate. You'll be spraying a dielectric fluid like a MMM FC72, this is how military radar systems are cooled. The...
Too much competition with Ham specialty outfits such as MFJ.
The only disadvantage of ham radio is the one it shares with aviation, boating, philately, knitting, numismatics, WikiAnswers, bowling, billiards, and any other hobby or avocation with the capacity to become addictive ... the risk that the devotee will develop a pursuit, attachment, and habit so...
Ham radio , owing to its social context, evolved, and is not a consumer product as is, perhaps a Walkie-Talkie. the technical editor ( he edited a variety of radio and electronics magazines- also science fiction stuff) Hugo Gernsback played indeed a big Brother, or Father Figure type role to the...
Not quite 75%. There are 35 questions on the Technician and General exams, of which 26 must be correct. There are 50 questions on the Amateur Extra exam, of which 37 must be correct.
In the related links there should be an scanner.
same as a standard fm/am radio transmitter, the difference is that it uses a much shorter wavelength
Hams are involved in Skywarn at times, which operates under the National Weather Service. They provide emergency weather information to the NWS for analysis and dissemination to the public.
One role is to prepare for a disaster. Hams have what is called  "Field Day", where they set up their equipment in an outdoor area,  using emergency power for their equipment. Another role is in  message handling. Some hams relay messages from private citizens to  friends and/or relatives in...
There are several ways. First, turn the scanner on and adjust the  squelch so that it is quite. Then press the manual button to flip  through the 16 channels. Stop on the channel you want to program.  Then, type in the frequency followed by the "E" key on the lower  right of the keypad. Hit the...
Yes Ham Radio and Amateur Radio are same. Amateur and Ham radio operators use two-way radio stations from their homes, cars, boats and outdoors to make hundreds of friends around town and around the world. They communicate with each other using voice, computers, and Morse code. Some hams bounce...
It's the same thing as amature
The most important fact to know is that you're required to have a government license before you do any transmitting. Check out the attached link to the American Radio Relay League ... the most informative and influential association of amateur radio in the USA for almost 100 years now....
In the United States ( different countries have different rules and policies_ since the Roberts Bill defined a difference between commercial operators ( such as those on Ships) and amateurs- around l9ll. at the time, all TRAFFIC was in Internaitonal Morse Code, which is no longer the case.
Probably from 'Amateur', (Hamateur). In the same way that amateur actors are known as Ham or hammy.
The use of radio are -- to move information from place to place, quickly -- to deliver energy into organic substances, such as with diathermy machines and microwave ovens
Maximum power usage is defined by part 97.313 of the FCC rules and regulations governing Amateur Radio. For repeaters, maximum power is determined by the antenna's H.A.A.T. (height above average terrain). This can be calculated by using the FCC's online calculator at: http://transition.fcc.gov/mb...

Yes - QRP simply means 'low power' - however CW is easier to hear than voice at low power as it is a single note.
  There are several ways. There are several books or guides in publication. Radio Shack generally has several, or check your local library. There are several web site dedicated to "scanner" frequency list. There are also links to monitor local frequencies available through most major Local new...
-- If the walkie talkie is designed to operate on more than one channel, then there's a switch on it that selects the channel. -- If it's not designed to operate on more than one channel, then you have to get inside, change some crystals, and maybe optimize some resonant circuits. Of course,...
Long distance communication is much less common on UHF bands than it is on LF, MF, or HF bands.Your question can be answered truthfully in so many ways, as long as any one of them does not claim to be the only correct answer. So the above answer is true, but all bands have potential for great...
If you aim a radio signal to a point just above the horizon (and above that) the signal hits the ionosphere waaaaay out there at a point faaaaar above the Earth. The result is that the ionosphere bends or "refracts" the radio waves, some of which shoot off into space, but the majority of which are...

Here are a few things that radio waves can do: 1. Communications (TV, Commercial radio, Ham radio etc.) 2. Heat things up, (Microwaves are just extremely short radio waves) 3. They can travel extremely fast (At the speed of light)
A licensed person using equipment to receive and transmit on approved frequencies as allowed based on their license.
I just bought one for $30.00, in the original box.
It seems to answer its own question. this is marine operation ( from ships and boats) on the Ham or Amateur radio wavelengths. Not to be confused with the various Marine bands used by Merchant shipping companies, Phone companies ( Marine Operator calling) etc. By the way radio waves carry greater...
first power up t then hit manual then go to channel 1 and hit 155.250 and do this for all of the channels :)
You can use co axial cable to make a very effective FM antenna.   Simply just strip back the insulation and then separate the two parts of the cable.   This will make a very good dipole antenna.
Recent examples include the September 11 attacks on the World Trade Center inManhattan in 2001, the 2003 North America blackout and Hurricane Katrina in September 2005, where amateur radio was used to coordinate disaster relief activities when other systems failed.On September 2, 2004, ham radio was...
(In the United States) you do not need a license to own a HAM radio. You may Listen to communications on a HAM radio without a license. However, you may NOT transmit on a HAM radio without a license.

You need to connect to a Comm port on a computer and use software found on the internet. It is fairly simple once you find a puter with the com port. I am not aware if a usb can be converted/used.
I am a ham radio operator. Radios can come in all different sizes. Some are as small or smaller then a deck of playing cards,(these are handheld radios), while others are the big boxes classically thought of as ham radios. ========================== I am too. A ham radio can fill a "relay rack" ...
Somewhat oddly, and this also applies to another federally-monitored (Hobby) prospecting, there are no statutory age requirements. there have been ( most exceptionally) some adult-coached Hams as young as 8 in the fifties. There are different categories of exams for different classes of operators (...
Along with a number of other states in the northwest, Oregon is part of the amateur '7' call sign area. It doesn't define anything else about the content, length, or format of the call sign, only that each amateur license granted for a station address in Oregon will have a numeral '7' in it.
That depends on the charging voltage, and on the current limit during charging.
He stated that he had worked in radio before. He was most likely some small-time talk radio announcer. It is nice to see a guy get a second chance... but to be honest I have mixed feelings about the opportunity that was just handed to him with no in-between time. Seems strange to me that someone...
Thold stands for throttle hold. one of the switches on the top is labelled th hold as well. If you have the throttle hold setting on you will need to flip the switch before you can throttle up. Its like a safety feature so the main rotor or prop doesnt start spinning while you are handling it.
No! CB power amps are very unlawful, and they can interfere with legal radio communications. (Like Amateur Radio)
There are many, many Hams who have portable VHF and UHF rigs, complete in a container with large batteries to run the radio, and often with a large (19" or more) antenna rising from their backpacks. In New York city, for example, when the World Trade Tower came down, most of the longer-distance ...
