I make it a point to operate terrestrial JT65 for at least a couple hours of
the contest. I'd certainly encourage others to do so... after all, it's made
for digging really quiet signals out of the muck. It's easily coordinated via
http://on4kst.org/ or http://www.chris.org/cgi-bin/jt65talk. Don't know why
it's not more popular, given all the EME nerds using JT65 through antenna
stacks and kilowatt amps between 144-1296 MHz.
You might want to also review replies to my thread "JT65 on 222 and above" of
28 Apr 2016, when I asked about calling frequencies. To summarize my
viewpoint, although just randomly squatting in the SSB segment is "okay," it's
not optimal. JT65 can pull out signals really close to the noise floor, so
knob-spinning is not the best approach, and not everyone knows or can reach the
web chat sites (for example, remote rovers). Besides, it's a logical,
well-established practice to have a calling frequency, QRG, call it what you
want, as a baseline where you can park the radio.
Please discuss, but I think "standard calling frequency minus 24kHz" makes a
lot of sense, resulting in 144.176, 222.076, 432.076, etc. It's close to the
standard calling frequencies, thus easy for knob-spinners to find and
compatible with equipment tuned for that area. And it avoids stepping on SSB
users (CW folks are more audible, and can filter more easily).
WSJT software suggest 144.489 on 2m for reasons which escape me, maybe WSPR
legacy. 144.100 is pretty dead, so while the band plan seems to allow it, I
think 144.076 would be off the beaten path. As stated previously on 6m the
convention is 50.276.
I've been working on another JT65-related post so will have to get that out
today too, in this vein. :)
