A range of frequencies
A list of what modes can be operated on a range of frequencies, per

The width of a frequency band outside of which the mean power of the transmitted signal is attenuated at least 26 dB below the mean power
of the transmitted signal within the band.
Refers to running your transmitter without an amplifier (in other words,
the "power out" is being produced entirely by the transmitter, without
any assistance from an amplifier).
Battery Memory Effect
Common to Nicked Cadmium (Ni-Cad), and Ni-MH (Nickel Metal Hydride)
batteries, the condition where if you fail to completely discharge the
battery prior to recharging, you will get considerably less usage time
the next time you use it. Lithium Ion (Li-ion) batteries are free from

Beat Frequency Oscillator
1. nickname for "satellite", in the case of Amateur Radio, examples include RS-12/13 (Radio Sputnik) and AO-40 (AMSAT-OSCAR).
2. brand name of a high-end, high quality directional wattmeter.
A signal produced within a radio, typically by it's microprocessor or
