The ARRL Bandplan on the website shows:
7.040 RTTY/Data DX
7.080-7.125 RTTY/Data
I don't know where the 7047 kHz frequency came from, but that choice kind of
surprised me when I first loaded FT8/FT4 onto one of my station computers a
couple of weeks ago. The FT8 frequencies are hard coded into the software, but
there are no pre-loaded frequencies for FT4. I had to research on-line to
figure out where they were.
The FCC limits for data are 7000 to 7125 kHz, (for Extras, and of course it
varies by class). Exactly what do you want the Board to do here, come up with a
recommended special ARRL bandplan for FT8/FT4?
