[ScanIndiana] The Frequency Spectrum

[scanindiana@mailman.qth.net]

VLF (Very Low):     3 KHz -  30 KHz
LF  (Low):         30 KHz - 300 KHz
MF  (Medium):     300 KHz -   3 MHz
HF  (High):         3 MHz -  30 MHz
VHF (Very High):   30 MHz - 300 MHz
UHF (Ultra High): 300 MHz -   3 GHz
SHF (Super High):   3 GHz -  30 GHz
EHF (Extra High):  30 GHz - 300 GHz

and above 300 Ghz is "Oh, My God!!"

My admittedly "old-fashioned" view of the frequency spectrum is based on
years of military usage, i.e.,
HF radios covered the 30-50 MHZ band;
VHF radios covered the 115-150 Mhz band;
and UHF radios covered the 225-400 Mhz band.
