Hi all,
Please allow me to ask about the split mode in the sense of a
necessity resulting from different frequency assignments in different
countries, i.e. a sort of special form of multi-band operation. The
typical situation is the QSO between a Japanese station and a station
in Region 1.
What is the recommanded setting in WSJT-X in order to operate under
such conditions while maintaining the "special" split at the TX side
in order to have the audio between 1.5 and 2 kHz ?
Best wishes,

Hi Claude,
supporting "legacy" split mode in WSJT-X would require a large
enhancement. For example some scheme that allowed each working frequency
to have an optional independent transmit frequency. I suspect the
requirement does not justify the amount of work as few bands and regions
suffer these non-compatible frequency allocations. On top band I doubt
there are enough stations active with good enough receiving station
aerials to take advantage, such that a wide bandwidth slot would be
required. Because of that a manual solution is probably the best. You
can create a new configuration and in that set
"Settings->Radio->Rig->None". You may need to do some work to get PTT
working in that configuration if you currently use CAT PTT. Once the new
configuration is selected you can manually tune your rig's split Rx and
Tx frequencies just like you would in other modes, be sure to pick a Tx
VFO dial frequency that allows you to use an audio offset between 1500
Hz and 2500 Hz.
I believe the regulators in Japan are addressing the incompatibilities
with other regions on 160m.
