Confirmed on the FTDX10: receiving on 14.018.98 and pressing SPLIT put 14.019.98
in the big display with "TX 14.019.98 (0 kHz)" under it. The radio was right —
RX 14.018.98, TX 14.019.98, up 1 kHz on CW — the panel was not.
RigState follows the ADIF convention where freq_hz is the TRANSMIT frequency, so
under split it is the OTHER VFO. Taking it as the main display showed the
operator the frequency they transmit on, and then an offset of that frequency
against itself: zero.
The header now reads the listening frequency (freq_rx_hz when split, freq_hz
otherwise) and the TX line shows the real transmit frequency and offset.
