  2. 70-centimeter band - Wikipedia

    en.wikipedia.org/wiki/70-centimeter_band

    American radio amateurs may use a maximum of one watt of radiated RF power, on any ham frequency authorized for data emissions, to control RC models. [10] Canadian radio amateurs may use any amateur frequency above 30 MHz for the control of RC models. [11] Plus or minus 5 MHz is a common repeater frequency offset in the 70 cm band.

    ATV operation in the 70 cm band is particularly popular, because the signals can be received on any cable-ready television. Operation in the 33 cm and 23 cm bands is easily augmented by the availability of various varieties of consumer-grade wireless video devices that exist and operate in unlicensed frequencies coincident to these bands.

  4. Radio spectrum - Wikipedia

    en.wikipedia.org/wiki/Radio_spectrum

    As a matter of convention, the ITU divides the radio spectrum into 12 bands, each beginning at a wavelength which is a power of ten (10 n) metres, with corresponding frequency of 3×10 8−n hertz, and each covering a decade of frequency or wavelength. Each of these bands has a traditional name.

  5. LPD433 - Wikipedia

    en.wikipedia.org/wiki/LPD433

    The frequencies used are within the 70-centimeter band, which is currently otherwise reserved for government and amateur radio operations in the United States and most nations worldwide. LPD hand-held radios are authorized for licence-free voice communications use in most of Europe using analog frequency modulation (FM) as part of short range ...

  6. Business band - Wikipedia

    en.wikipedia.org/wiki/Business_band

    The industrial and business frequencies, sometimes also known as "business band radio," and the eligibility requirements are listed in 47CFR90.35. [1] Frequencies are licensed on a non-exclusive basis, although fixed stations and mobiles operating in a defined area are issued licenses only following frequency coordination [ 5 ] to assure ...

  7. Amateur television - Wikipedia

    en.wikipedia.org/wiki/Amateur_television

    In North America, amateur radio bands that are suitable for a television signal (wide enough to fit such a signal) are higher in frequency than VHF broadcast TV. The lowest frequency ham band suitable for television transmission is 70 centimeters, which is between broadcast channels 13 and 14.

  8. 1.25-meter band - Wikipedia

    en.wikipedia.org/wiki/1.25-meter_band

    Both bands (as well as 70 centimeters) were natural harmonics of the 5-meter band. Amateur privileges in the 2.5-meter band were later moved to 144–148 MHz (becoming the modern-day 2-meter band), and the old frequencies were reassigned to aircraft communication during World War II. At that time, the 1.25-meter band expanded to a 5 MHz ...

  9. 4-metre band - Wikipedia

    en.wikipedia.org/wiki/4-metre_band

    The 4-metre (70 MHz) band is an amateur radio band within the lower part of the very high frequency (VHF) band.. As only a few countries within and outside of Europe have allocated the band for amateur radio access, the availability of dedicated commercially manufactured equipment is limited.
