Hi Jeff,
Maybe because there are some other countries than USA in the world... (with
diferents band plan) 😉

À : cq-contest@contesting.com Objet : Re: [CQ-Contest] 40M FT4 Frequency
Why not move all digital communications (including FT8/FT4) above 7100 ?
Here is the FCC frequency allocation for the lower part of 40 meters the US:
7.025-7.125 MHz : CW, RTTY/Data
The same applies to 20/15/10 meters as well.
14.025 -14.150 MHz CW, RTTY/Data
21.025-21.200 MHz: CW, RTTY/Data
28.000-28.300 MHz: CW, RTTY/Data
I don't think that segments above .100 are used much by anyone in the
US. I've never understood why the digital mode frequency recommendations
are in the top part of the CW band to begin with. Maybe one of you
serious digital guys can explain this reasoning?
