Hi Reino & all,

Saku's proposal does exactly the same without any modification of the code or the protocol. If the partner station refuses deliberately to change its frequency or if (s)he cannot copy the QSY free style message, you can only continue to repeat in the protocol sequence.

Please remember that what you see on the waterfall of your monitor, can be very different from that what your partner station sees on his/her monitor. This is especially important to remember because your signal can be scrambled by another station, which you cannot see on your own monitor. It can be very helpful to try to change your own frequency if you see that your partner cannot copy your signal.

Best wishes,

There are so many times on FT8 or FT4 that the station you are in QSO
with is buried in QRM by a signal they probably don't even know is on
their audio frequency.

On future releases of FT4 or FT8, if there is ever a spare bit in the
message formats, I propose adding a "please QSY to my tx audio
frequency" bit.   There would be a "Pse QSY: button on the user
interface that would be off by default.

There would be an indicator to the other op that a QSY is requested,
and it is up to them whether or not to hit the up arrow button to
sync TX frequencies.
