I think most would agree that a QSY reminder would help alleviate congestion on the calling frequencies. It seems most are not aware of this practice and it will only get worse as VarAC becomes popular. A simple approach might be to add a reminder in the form of a banner that scrolls across the bottom of the GUI?

Done. will be released in V3.1
If you stick to the CALLING QRG for too long it will show on both ends for a certain period of time as a soft reminder.
