Hi,
I found an interesting 3Y0Z bandplan scheduled to operate in early 2018 and I
wonder they may violate IARU and local (JA) bandplans and it may create trouble
for us.
For example, on 20m, it say that 3Y0Z transmits TX= 200-400Hz on QRG=14.067MHz
and we are instructed to transmit TX=400-2,00Hz on QRG=14.067MHz. This means we
are operating on CW band.
See 3Y0Z Band Plan and FT8 operation operation notice (* mark).

I searched with “Bouvet” on this mailing lists and found the following thread.
I am not sure they are appropriate reference or not but I attached for your
review. Unfortunately, I am against Rich’s recommendation to use
14.112-14.125MHz by the reason that FT8 is a NBD and it can not be ALL Modes by
the definition of IARU (?).
Does anybody know the process to create FT8 band plan of this DX-pedition?
Regards,
