[SOC] MCW, again.

[Joe Pontek Sr]

This is not completely accurate.

An MCW is made up of components determined by the method of generation.  
If standard AM method
with a single tone is used, there will be the carrier and then two side 
tones, ie. 400 Hz tone used to modulate
a carrier of 5,000 kHz, you will have carriers at 4,999,600 Hz, 
5,000,000 Hz and 5,000,400 Hz.

Now, depending on your receiver's band width, you might hear a single 
carrier at each frequency, a beat
tone od 400 Hz if you hear two carriers at the same time and further 
mixes with a wider bandwidth.  The
beat note(s) is(are) made in your receiver.

In the above example, the bandwidth only 800 Hz, not like a single 
sideband suppressed carrier voice
signal of about 2,700 Hz.

Too many times, it is a P poor receiver causing garbage you hear on the 
bands or poorly used receivers
by the operators.
