	Citizens' band radio - Wikipedia, the free encyclopedia
		Citizens' Band radio (CB) is, in the United States, a system of short distance radio communication between individuals on a selection of 40 channels within the single 27 MHz (11 meter) band.
		While the extended propagation characteristics on this band was of considerable interest to radio hobbyists, interference from distant stations limited the usefulness of CB for its original purpose.
		CB radio is still a near-universal method of communication among semi truck drivers in America and also remains very popular in rural areas with farmers and hunters, plus sometimes even acting as a sort of "party line" phone system in deep-rural areas too far in the boonies to have phone lines.

	Band (radio) - Wikipedia, the free encyclopedia
		A band is a small section of the spectrum of radio communication frequencies, in which channels are usually used or set aside for the same purpose.
		Each of these bands has a basic bandplan which dictates how it is to be used and shared, to avoid interference and to set protocol for the compatibility of transmitters and receivers.
		These are the parts of the radio spectrum, and not its frequency allocation.

	Radio 4 (band) - Wikipedia, the free encyclopedia (Site not responding. Last check: 2007-10-20)
		Radio 4 are a band from Brooklyn who formed in 1999.
		The band is a five-piece, comprising Anthony Roman (Vocals/Bass) (he used to be in), Tommy Williams (Vocals/Guitar), Gerard Garone (Keyboards), Greg Collins (Drums), and P.J. O'Connor (Percussion).
		They cite a variety of influences, including Gang of Four, Mission of Burma, Primal Scream and, but their lively punk-pop sound combined with their militant political stance inevitably means that they are most often compared with The Clash.

	Antique Radio Classified--Vintage Broadcasting
		One has to remember that radio broadcasting for entertainment evolved from a medium that was generally being used in a service capacity.
		There was some variation within the band, as stations would sometimes shift their positions a bit when interference became excessive.
		The band expansion helped relieve the congestion, of course, but with more than 600 stations on the air by the mid-1920s and with the vastly improved receiving equipment, the situation was hardly any better, especially at night.

		On 8/9/2004, the declination at which the radio telescope was pointed was changed to -28.85 degrees, which is the declination of SGR A. An observation file commenced at 7 pm EST on that date was the first of this series of observations of SGR A at its declination.
		The oral presentation is on the analog components of a C band radio telescope and the poster paper is on the SETI range of a radio telescope.
		The data from the wide band receiver, when compared to the data from the regular receiver, clearly established that the negative spikes in the data from the regular receiver were caused by unwanted signals outside the passband of the regular receiver but inside the passband (the entire C band) of the wide band receiver.

	National Panasonic RF-8000 24-Band Radio
		Only one band may be received at one time; the active set is indicated by a small red LED indicator immediately to the left of the each bezel.
		The dial lighting illuminates the S-meter as well as the two band scales; lighting is on all the time when the RF-8000 is connected to the AC mains, and may be turned on using a momentary switch when operating from its internal battery supply.
		These bands use internal fixed ferrite bar antennas (three of them.) For this reason, instead of being rated in microvolts, as if the signal was applied via an antenna wire, they are rated in "microvolts per meter", as the actual antenna signal field intercept is a known quantity.

		Answer: RadioShack radios are designed to operate within the legal limits set by the FCC; operating outside of the licensed band is illegal.
		The radio should be taken in to your local RadioShack store for repair; they will send it to the nearest Service Center.
		Answer: It is normal operation for this radio to default to VFO operation when turned on; there is no way to set it to default to memory operation or to the last format used.

	Swing In To Our Mainstream Jazz And Big Band Radio Show

		Citizens' band radio (CB) is a system of short distance communication between individuals on a selection of 40 channels within the single 27 MHz (11 meter) band.
		Both GMRS and Amateur Radio do require licenses and Amateur (Ham) Radio also requires the passing of exams before a license and call sign is issued by the FCC.
		CB is still a popular hobby in many countries though its meaning as a method of communication has diminished recently, due to new developments such as the internet and mobile phones.

	FAQ: CB (Citizen's Band) Radio Answers
		Answer: No. CB radios in the United States have the following restrictions: operate only on the 40 26-27 Mhz CB channels, they must be FCC approved for CB use, and have 4w AM/12W pep SSB maximum output power, license free.
		There is no commercial license or ham license that allows the user to run higher power, use extra channels or use modified amateur rigs in the 11M 26/27Mhz CB radio band.
		By operating on a narrower band, the effective range is increased; however,.the signal does not sound as clear as an AM signal.

		While the design gives the radio a solid look, we were a little disappointed that the E350--unlike many radios made 20 years ago--is completely made of plastic (with the exception of the speaker cover).
		The radio supports battery and AC power, but we were in for a surprise when we opened the battery compartment.
		Not only can the radio run on four D batteries, but there is also another, smaller compartment that accepts four AA cells--a nice little bonus if you need temporary power and you only have the smaller cells on hand.

		Where the rules use the term "CB station", that means a radio station transmitting in the CB Radio Service.

	AM Band DXing
		Back in the 1920s, the first radio stations were anxious to know how far away they were being heard.
		Regional stations often use different power levels and directional antennas for day and night operation; since AM band signals travel further at night, regional stations will reduce transmitter power and use a "tighter" directional antenna between their local sunset and local sunrise.
		One practice that has continued since the early days of radio is the "DX test." FCC rules allow stations which must reduce power or change antennas at night to briefly test using daytime power and antennas during an "experimental period" from midnight to sunrise.
