[ICOM] IC-7000 AM Modulation Problem

Adam,

Obviously the Canadians run more SSB power 2.25 kW output to make it just as 
reliable as their legal 750 W Morse CW output.  What a difference!

Hi Dave,

Canada is somewhat more generous in this respect. Industry Canada
regulations allow Advanced licensees 2.25kW PEP output (SSB), and 1kW DC
input to the final (or 750W carrier output)  for all other modes.

The other side of the coin is that transmitted occupied bandwidth is limited
to 6 kHz per channel (at -26 dBc) on all HF bands except 30m (1 kHz) and 10m
(20 kHz). So "high-figh" AM ops are limited to 10m.

Cheers for now, 73,
Adam VA7OJ/AB4OJ
