I have only been Monitoring 30M as this is where I read that FT4
was going to operate. In the past few days I have noticed 5/6 FT4
signals operating between 10.140 and 10.142. This is right in the
middle of the PSK31 Frequency.

I went back and looked at the current ARRL's band plan chart and
they don't differentiate between any of the digital modes, other
than to link RTTY with the digital. Only other exception is SSTV
which is in the phone bands.
So, it's up to us. Looking at the ham bands charts show the
dividing line between data and phone at 18.110. And of course the
ARRL code practice is broadcast on 18.0975, inferring that maybe
below 18.100 is for CW? Another point, from a practical POV, is
that most of our rigs have a 3KHZ bandwith, and the waterfall
display is dependent on the receiver's bandwidth, falling off at
or near 3,000.
So, maybe, the next slot up from 18.100 is 18.103? I know that
18.097 was suggested, but that falls over the ARRL's Morse code
Another point is FT4. Has it found a home yet? There will always
be 'new' modes coming at us. So what is a good strategy moving
I don't know.
You guys are a whole lot smarter than me in figuring this stuff
