Because setting frequency can change mode and setting mode can change frequency on various rigs it is necessary to set a frequency by first setting a frequency which gets to the correct band and potentially band stack register. Then to set the mode to ensure that any band remembered mode is cleared. Then set frequency again in case the prior mode change moved the frequency (e.g. CW correction). Then set mode again because some rigs set the mode according to frequency. Who would have thought setting the rig frequency via CAT could be so complicated :( TODO: Even this is flawed on some Yaesu rigs that must be band changed to select some settings like aerial socket and pre-amp settings.

WSJT-X implements JT9, a new mode designed especially for the LF, MF,
and HF bands, as well as the popular mode JT65. Both modes were
designed for making reliable, confirmed QSOs under extreme weak-signal
conditions. They use nearly identical message structure and source
encoding. JT65 was designed for EME (“moonbounce”) on the VHF/UHF
bands and has also proved very effective for worldwide QRP
communication at HF; in contrast, JT9 is optimized for HF and lower
frequencies. JT9 is about 2 dB more sensitive than JT65A while using
less than 10% of the bandwidth. World-wide QSOs are possible with
power levels of a few watts and compromise antennas. A 2 kHz slice of
spectrum is essentially full when occupied by ten JT65 signals. As
many as 100 JT9 signals can fit into the same space, without overlap.
WSJT-X offers a “bi-lingual” operating mode in which you can transmit
and receive JT65 and JT9 signals, switching between modes
automatically as needed. Displayed bandwidth can be as large as 5
kHz. If your receiver has as upper-sideband filter at least 4 kHz
wide, you can have all the typical JT65 and JT9 activity on screen at
once, available for making QSOs with a click of the mouse. Even with
standard SSB-width IF filters, switching between JT65 and JT9 modes is
quick and convenient. Be sure to read the online WSJT-X User's Guide.
