I don't have a K3, but I operate JT9 and JT65 with a K2. If youuse the
K3 in USB mode, then it works the same way as it does for the K2. By
convention, the subbands are specified as VFO frequencyon USB. On30
meters. the subband is 10.130. You just leave the VFO (receive) on that
frequency. When the software modulates the signal in transmit, tones are
produced based on the VFO frequency. The transmit frequency doesn't
change per se. But the modulation causes sidebands to be generated above
the VFO frequency which are the WSPR mode tones. Everything is based on
the VFO frequency. In fact, under rig control like HRD or omni-rig, the
WSPR software presets your rig to the convention-defined subband VFO
frequency.

When using WSPR the TX and RX frequencies are not the same....for example on
30m the RX is 10.138700 and the TX is 10.140200. For those of you using the K3
does your read out on the K3 change to the TX freq then the rig goes into
transmit? Mine is not and not sure if this is normal or if I have to set
something to show this.
Thanks
