Exchange 'CQ Slot Wait' time and 'invalidate' CQ.

Hi,

Would it be possible to exchange the 'CQ Slot Wait' time in addition to the slot. This could then be used to visually mark a CQ beacon as 'expired'. While the 'CQ Slot Wait time' is active the color of the 'Last heard CQ call' could be different or have an other visual marker then when the timer has expired and the other station is probably QSY'ed back to the calling QRG.

Regards,

Erik
