This would be quite useful based on my recent observations on 6m. We all suffer when someone inadvertently transmits across two periods. I have on occasion sent something like

PA0XX CLOCK or indeed DL0XX, ON0XX and G0XXX of course :-)

It normally works but it feels wrong because the station does not know who the message is from. I don't like doing it and it really is a last resort. Other problem is TX distortion/overmodulation/wide signals.

Messages to cover that would be useful, after all no one want to radiate a bad signal or cause unnecessary interference do they? We need a better expression than PA0XX WIDE, it seems too confrontational.

I do hope that when conditions on 6m get even better that alternative frequencies are used.

Having just watched another station sending a "CHK TIMING" message in
FT8, which is obviously not likely to succeed...

I was wondering if a non-timing-critical "message" could be added to
the protocol, e.g. four continuous tones - or some such combination
that is unlikely to happen randomly, but could still be interpreted by
someone (and/or the software) who's clock was too far out - maybe a
big "CHECK YOUR PC CLOCK" message could be displayed in their client
:)
