It has come to my attention that the default FT4 frequency on 40M has
been set to 7047.5 As N5TM put it on Slack VHF-Chat, "this is going
to start an all out war on 40M." I couldn't agree more.
I'm very active on the HF bands, and there's a LOT of CW activity all
the way up to at least 7060. Everything from QRP to county hunters to
state QSO parties, to QRS ops. Whoever made that choice seems either
pretty inconsiderate or pretty ignorant of long established practice
on the band. I haven't looked carefully at other bands.

Jim,
the IARU Region 2 band plan shows 7040 - 7047 as available for up to 500
Hz bandwidth digital modes as well as CW. It also lists 7047 - 7050 as
available for up to 500 Hz bandwidth digital modes including automatic
stations as well as CW. Those are globally coordinated with similar
slots in the Region 1 and 3 band plans. Remember that FT4 is intended
for contest use and most contests will make recommendations on
frequencies to be used. The original suggestion was 7047 but as that
clashes with the ARRL code practice service and other ARRL services we
moved up 500 Hz to steer clear of that well used spot.
