receiver to 474.2 kHz in USB, and leave the 'base frequency' (=audio
frequency of the lowest WSQ tone) set to 1000 Hz. That way, you can have
WSQ, WSPR, and JT9 (WSJT-X) running on the same PC, connected to the same
receiver."

Perhaps in rural regions or other areas where nearby local activity is not
present but here in the greater Vancouver region (VE7), there are presently
6 VERY active stations on 630. The ONLY way that we can work weak signals is
to co-operatively work together, and that means that we all work hard at
transmitting only on the odd-minute sequence for two-way work. There is
little hope for any of us hearing weak signals if any of the other locals
are transmitting as, thanks to the amazing groundwave on this band, everyone
is S9+++ at each others location!
This would still be fine if WSQ were a non-random tx mode but having two-way
work on WSQ would mean that the 'tx on odd' rule that is our present
salvation, would no longer be possible. Our own locals would be shut-out of
two-way work using this mode, should they want to maintain the co-operative
and presently well-working local protocols here in the VE7 region. Even when
the earlier WSQ experiments were rolled-out way up at the top end of the
band, there was still significant audio harmonic fallout from these very
strong signals, spread out throughout the JT9 / WSPR segment but they were
not strong enough that one could not pick a hole between them to use.
Respectfully, I would strongly urge that any precedent for establishing a NA
two-way WSQ window be kept as high in the band as possible and definitely
not in the JT9 / WSPR region as in a high signal environment (that may
eventually come to your region as well), the two modes are certainly not
compatible.
