For convenience the radio frequencies are split up into areas called: M.F. (Medium Frequency), H.F. (High Frequencies), V.H.F. (Very High Frequency), U.H.F. (Ultra High Frequency) and Microwave.
Medium Frequency. From 300KHz (0.3MHz) to 30MHz.
Local communication. VERY large antennas. Commonly uses S.S.B. and C.W. sometimes A.M. is still used. RTTY (radio teletype), AMTOR, PACTOR, SSTV (Slow Scan Television) and Packet (at 300 Baud) are all used on the M.F. band.
In Canada, only one band in the Medium Frequency range may be used for Amateur radio. 160 meters (1.8MHz to 2MHz).
