Amateur Radio

Parent Category: Hobbies & Collectibles
Amateur radio (also called ham radio) is the private and licensed use of selected radio bands for recreational purposes, experimentation, and emergency communication. Amateur radio operates under rules limiting the maximum power and technical characteristics of each transmission.

be, kind no nonsense respect let other people talk DO NOT USE THE EMERGENCY CHANNEL(S) (unless it is an emergency) if they do not answer straight away, they may be busy, so justwait, and in 3-5 minutes if there is no reply, you can try again. if you need help with the radio operating, do not ask...
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 lookssomewhat larger than if you only look at...
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...

When you set up aUniden Bearcat BC148XLT base scanner, you must program thefrequencies you want to scan based on your area's frequencies. Youdo not need to include weather frequencies, because the BC148XLTincludes weather frequencies pre-programmed in the base. You canadd frequencies to your scanner...
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,...
you can PROGRAM it by following the directions here: http://support.radioshack.com/support_electronics/59448.htm P.s. it helps if you can spell PROGRAM (not pragram).

UHF is an acronym for ultra-high frequency . Frequencies in the UHF band (300 to 3,000 MHz) are/were commonly used for television broadcasting and such two-way communication applications as cordless phones and walkie-talkie radios.
A less technical answer of how you hear the police through a scanner is much like how you get to listen to music on your radio. There is a transmission site that broadcasts over an area. Equipment such as your scanner is setup to capture those frequencies and play it through the speaker. Many...
Well, the origin of Weegee is Mario Is Missing, when he had a sprite which had him in this odd position.

I assume you mean radio scanner frequencies? If so, RadioReference is an excellent resource: http://www.radioreference.com/ If you are talking about error codes from your car, you might have to Google those. I'm not sure if OBDII codes are universal (they very well may be). You could do a search...
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.

Bandwidth is the amount of information that can come through. Thefrequency is how quickly the information can come through.
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...

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.
Follow the link below to download/print the manual for your scanner. It will answer all of your programming questions: http://www.uniden.com/pdf/BC72XLTom.pdf
The Best source I've found is at the related link below, but you can frequently find a good buy on eBay.
Your scanner uses a standard BNC antenna connector. Check eBay and ScannerMaster.com for available antennas.

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...
The frequencies for aircraft communication vary greatly by location and operator. Your best bet for following the action in your area is to search the civil aircraft band (108 - 137 MHz) and, if your scanner covers it, the military aircraft band (225 -380 MHz). Note the active frequencies that you...
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...
No. Answer #2 As far as fixed wing airplanes it is possible to hear the communications from either the aircraft or the control tower or both depending on the distance from them to you. Other types of aircraft such as helicopters can be listened to as well if they have an open system and can be...

Ham radios are also called amateur radios. SR-955 HPC and SR-655 HPC are the best amateurradios. Below are some of the feature of SR-955 and SR-655. Have a high power radio, 7 color frequencydisplay, dimmer control, its also clarifier and Pc programmablesystem.
The dimensions of the antenna completely depend on the frequency band in which you plan to operate the radio. This is all covered in the study materials for the license exam. You do have a license to operate that transmitter, don't you ? ! ?

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) then 234/3.56 = 65.7 feet Next buy a spool of...
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...
