Morse code a.k.a. CW (Continuous Wave):
Continuous wave is the name given to an early method of radio transmission, in which a sinusoidal carrier wave is switched on and off. Information is carried in the varying duration of the on and off periods of the signal, for example by Morse code in early radio. In early wireless telegraphy radio transmission, CW waves were also known as “undamped waves”, to distinguish this method from damped wave transmission.
CW – Morse code was and still is the most common form of communication that will get through when nothing else will.

Voice mode includes the following:
SSB (Single Side Band) There is both Upper side band and Lower side band.
Single side band modulation or single side band suppressed carrier modulation (SSB – SC) is a refinement of amplitude modulation which uses transmitter power and bandwidth more efficiently. Amplitude modulation produces an output signal that has twice the bandwidth of the original base band signal. Single side band modulation avoids this bandwidth doubling, and the power wasted on a carrier, at the cost of increased device complexity and more difficult tuning at the receiver.

AM – Amplitude Modulation
Amplitude modulation is a modulation technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. In amplitude modulation, the amplitude (signal strength) of the carrier wave is varied in proportion to the waveform being transmitted.

FM – Frequency Modulation
Frequency modulation is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. This contrasts with amplitude modulation, in which the amplitude of the carrier wave varies, while the frequency remains constant.

Note: If you know of any frequency(s) that are used on a regular basis for Prepper or Survivalist nets feel free to email me with them and I’ll go have a listen and perhaps check in. If it’s a good source I’ll list them on the site here.
