France BAND---- ( France will honor licenses from other countries using CEPT-approved radios.-- 40 channels, same frequencies as USA 4W max power (26.965 - 27.405 FM); Radios using this band are marked "PR 27 GB" or "CEPT PR 27 GB" and are CEPT-approved. )

Free band---- ( A band of frequencies below channel 1 and above channel 40 that are - sort of - free.
Some CB'ers modify their radios to use the Free band, though it is illegal in Canada and the US. )

F Region---- ( The HIGHEST ionospheric region) the F Region
refracts radio waves and returns them to earth. During the day this Region often splits into Two Regions called the F-1 and F-2 Regions. The height of the F region varies greatly depending on the time of day, season of the year and amount of Sun Spot activity. )

Frequency ---- ( The rate of oscillation (vibration).The rate of change of an ac voltage or current or The number of complete cycles of an alternating current that occur per second; Audio and radio wave frequencies are measured in Hertz.(Hz) (cycles per second). )

Frequency Coordination---- ( Allocating repeater input and output frequencies to minimize interference between repeaters and to other users of the band. )

Frequency Coordinator---- ( An individual or group responsible for assigning frequencies to new repeaters without causing interference to existing repeaters; An entity, recognized in a local or regional area by amateur operators whose stations are eligible to be auxiliary or repeater stations, that recommends transmit/receive channels and associated operating and technical parameters for such stations in order to avoid or minimize potential interference. )

Frequency Modulated (FM) Phone---- ( The type of signals used to communicate by voice (phone) over most repeaters. FM is a method of combining an RF carrier with an information signal, such as voice. The voice information (or data) changes the RF carrier frequency in the "modulation" process. ( see Amplitude modulation). As you might suspect, we use voice or data to vary the frequency of the transmitted signal. FM broadcast stations and most professional communications (police, fire, taxi) use FM. VHF/UHF FM voice is the most popular amateur mode. )

Fundamental Overload---- ( Interference resulting from fundamental signal of a radio transmitter. )

Fuse ---- ( a thin metal strip mounted in a holder. When excessive current passes through the fuse, the metal strip melts and opens and protects the circuit. Fuses are rated in amperes and voltage and time to activate - fast blow or slow blow. )
