The government and the military, in short.

They specify frequency in terms of the center frequency of the occupied
bandwidth or channel width. Hams use the transmitted frequency for all
carrier-present modes and the suppressed carrier frequency for SSB, SSTV,
etc.

So, if a channel is 2.8 KHz wide and the FCC defines the center frequency
for the channel - and the R&O clearly says "center frequency" - then the way
our rigs are set up, we have to set the dial to that specified center
frequency and then lower the reading by 1400 Hz to put our
suppressed-carrier frequency on the lower-frequency edge of the channel such
that our occupied bandwidth will run from that edge upward 2.8 KHz.

It *is* different!   <:}

or minus 1400 KHz.?  Where did this come from?
