	27MHz FCC Bandplan
		The U.S. FCC bandplan used in Citizens' band radio assigns 40 numbered RF channels between 26.965 MHz (Channel 01) and 27.405 MHz (Channel 40), with channels generally spaced on a 10 kHz frequency raster[?].
		There are odd 20 kHz channel spacings between channels 3 and 4, 7 and 8, 11 and 12,15 and 16 and 19 and 20.
		These frequencies can also be used by remote controlled aircraft[?] but are not recommended for use due to interference by CB radio in close proximity.

		The FCC saw through the charade, and imposed their rather draconian measures in order to cut down on illegal high powered CB operations, particularly in the "10 1/2" meter band, between 27.4 and 28 Mhz.
		On March 24, 1978, the FCC announced that "All prior call sign policies and procedures, written or unwritten, are canceled and hereby replaced".
		FCC tests showed that a signal 40 db stronger and only 2 khz away would not cause harmful interference to the received signal.

		The U.S. FCC bandplan used in Citizens' band radio assigns 40 numbered radio frequency channels between 26.965 MHz (channel 1) and 27.405 MHz (channel 40), with channels generally spaced 10 kHz apart.
		These frequencies cannot be used by remote controlled aircraft, due to interference by CB radio in close proximity, which could crash the plane or helicopter into the ground, an object, or even a person.
		The 27 MHz CB27/81 Bandplan is a list of the channel frequencies for UK-only FM CB radio CB radio in the United Kingdom.

		The use of handles instead of call signs is related to the common practice of using the radios to warn other drivers of speed traps during the time when the United States dropped the national speed limit to 55 mph (90 km/h) beginning in 1974 in response to the 1973 hike in oil prices.
		All frequencies in the HF spectrum (3–30 MHz) are able to be refracted by the existence of highly charged particles in the ionosphere.
		It is recorded that, before CB radio arose, the Afrika Korps in North Africa in WWII used 27 MHz for battlefield communications, thinking that it could only be heard locally; but skip was strong at the time, and the messages were routinely monitored in the United Kingdom.

		The 150-470 MHz frequencies have been the primary home of CI voice systems, but they cannot be the only available home in future without substantial risks to the safety, security and reliability of CI infrastructure and personnel.
		Moreover, the FCC in its BBA Decision stated that it believes that it retains the authority to allocate “Public Safety” spectrum according to the former, traditional Public Safety definition, which excludes CI.
		Given the FCC’s acknowledgement of the critical nature of utility and pipeline communications, the FCC must not wait until these severe, life-threatening consequences occur before enacting sufficient protections, in the form of spectrum protected from harmful interference from incompatible uses.

	CB Radio or Citizens' band radio Information All About
		For the 27 MHz/11-metre band however, the only persons who could legally operate transceivers were licensed radio amateurs who had passed a technical examination, and most had nothing but contempt for the persons operating illegally on the 11-metre band.
		In 1980 a total of 40 channels was approved for 27 MHz band and it was aligned with the 40 channels used in the USA.
		As 27 MHz is a relatively long wavelength for mobile communications, the choice of antenna has a considerable impact on the performance of a CB radio.

	More Broadband (BPL) Spectrum at 700 MHz?
		If the FCC is in need of more frequency space to provide every computer user broadband access; we ought to make a deal with them.
		He also said Congress should ask the FCC to look at secondary use of broadcast spectrum in areas where it is underused and to issue an order asking that unlicensed devices be allowed to operate in television broadcast spectrum at locations and times when the spectrum isn't being used.
		The former FCC chairman contends that the mandated 85 percent threshold of digital signal penetration that allows broadcasters to keep analog UHF spectrum has been crossed, if only the FCC would correctly count the numbers it already has accumulated.

		In addition to bidding rules, the FCC is also considering two plans that slice and dice the spectrum into allocations of 5 MHz, 5.5 MHz and 10 MHz.
		The 60 MHz block of spectrum up for grabs is considered “beachfront property.” As a result, 700 MHz providers are expected to be able to operate systems at lower cost and with fewer towers than wireless incumbents located higher up on the spectrum chart.
		Barring a sudden policy shift, the FCC is planning to allow cable and phone companies — which control 80% of the residential broadband access market, according to the agency — to put up the necessary billions to nullify any over-the-air threat to their lucrative high-speed data business.

		Although all of these recommendations have not been approved by the FCC or NTIA, we believe our preparatory process is best served by furnishing the public with the widest opportunity for comment on the efforts of our Advisory Committee.
		This would yield 10 MHz of MSS downlink spectrum that could be paired with the 10 MHz of MSS uplink spectrum within the 1675-1690 MHz band (see Recommendation 3).
		The 1492-1525 MHz band is already allocated for MSS in Region 2, but the U.S. has not implemented this allocation because of its use of the 1435-1535 MHz band for aeronautical telemetry.

	FM broadcast band - Wikipedia, the free encyclopedia
		Currently in Canada and the United States, each channel is numbered from 200 (87.9 MHz) to 300 (107.9 MHz) in increments of 1 (200 kHz).
		Originally, the FCC devised a bandplan where stations would be assigned at intervals of 4 channels, or 800 kHz separation, for any one geographic area.
		In the late 1980s, the FCC switched to a "bandplan" based on a distance separation table using currently operating stations, and subdivided the class table to create extra classes and change antenna height limits to meters.

		After World War II, the FCC moved FM to the frequencies between 88 and 106 MHz on June 27, 1945.
		It is divided into 100 channels, each 0.2 MHz wide, designated "channel 200" through "channel 300." In actual practice, no one uses these channels numbers; the frequencies are used.
		Because the lowest channel is centered on 87.9 MHz the tenths digit of the center frequency of any FM station in the United States is always an odd number.

	Low Cost Wireless Network How-To - Fear
		For frequency hopping systems, at least 75 hopping frequencies in a pseudorandom hopping pattern, separated by at least 25 kHz, shall be used, and the average time of occupancy on any frequency shall not be greater than four-tenths of one second within a 30 second period.
		All spurious emissions outside 22 MHz of the center carrier must be lower than 50 dB relative to the center frequency.
		Systems operating in the 2400-2483.5 MHz band that are used exclusively for fixed, point-to-point operations may employ transmitting antennas with directional gain greater than 6 dBi provided the maximum peak output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna exceeds 6 dBi.

	Band Plan - elmers Forum at eHam.net
		I have found some bandplans on the internet that are just "gentleman's agreement's" and some of the information contained in them are plain obsolete for the most part.
		My policy and personal advice is to always follow the bandplan as outlined by leading authorities such as the FCC or the ARRL.
		Of course, one must always consider that bandplans are not always inscribed in stone and certain operating activities and variations will occur.

	Broadband Wireless Internet Access / WiMAX News: FCC Creates Broadband Radio Service
		As expected, the FCC released its Notice Of Proposed Rulemaking (NPRM) for the MMDS/ITFS band at 2.5 - 2.69 GHz.
		Instead of carving the band into 6 MHz channels, the band is repartitioned mostly into 16.5 MHz "Blocks", leaving seven (7) 6 MHz channels in the middle of the band primarily for continued operation of television broadcasting.
		One interesting wrinkle is that the new blocks in the plan are multiples of 5.5 MHz channels, not 6 MHz channels; the "extra" space was used for guard bands to buffer the broadcast portion from the communications portions of the band.

	Citizens' band radio Summary
		Although the Federal Communications Commission (FCC) first introduced it in 1947, the CB did not experience its heyday until 30 years later, when hundreds of thousands of automobile and tractor trailer drivers installed them in their vehicles.
		In order to popularize the device among individuals for their personal use, the FCC, in 1958, opened up part of the broadcasting spectrum originally reserved for ham radio operators.
		Although one did not need to obtain a license to operate a CB radio, the number of licensees shot up dramatically from 1973 to the end of the decade, when more than 500,000 people were applying for licenses each month in direct response to cultural shifts at the time.
