[CQ-Contest] More CQWW SSB spot analysis

[Peter Voelpel]

Hi Ranko,

You are wrong, we are not allowed to have signals across band edges.
We need to know the bandwith of our signal and the mode to be sure we are
within band limits.
We are not allowed to use 14350 USB at all.
With a small filter 14347 KHz will be the highest usable frequncy by using
USB.

You are not allowed to work DX on 3802 KHz LSB in Europe either

Dear Steve,

You are not right. In band plan definition of frequency allude carrier
frequency. Width or structure of signal is nothing what users have to know
about. For example, TV signal width is 8MHz, and exact frequency of TV
signal is defined with carrier frequency. 

As structure of SSB is as it is, transmitting "out of band" happened
following your philosophy when someone transmit USB on upper edge of band or
LSB on lower edge of band. But users are responsible to take care about
caries frequency, and only CARRIER frequency is parameter defined in
national band plans.

You have to know that USB mode is SSB side band defined also for users
allowed to use frequencies above 14350 and USB shift will go on the same
side of band. Everything is in perfect order then.
