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...

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...

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...

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...

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...

10 and 12 metre band are both capable of it. Six metre band can do it sometimes, but it relies on very particular 'sun spots' of charged electrons to bounce the signal (which would otherwise go straight through the ionosphere under normal conditions) back to earth.

You can check the FCC website, and they will have a searchable database of all the Hams in the United States. You can also go to QRZ.com, or ARRL.com and they also have the same information.
Try the Radio Relay website (see related link at the bottom). I know I was able to listen to Johnston County on there (as well as Wake, Durham, and Orange), so I'm pretty sure Onslow would be on there, as well. At a very minimum, you should be able to get something from Jacksonville.
