It would be very convenient that the timer would be reset when you change the band and you want to announce your presence on a new band. I use to look for the higher frequency band where MUF pomises greater hop distance and I would like to be able to send a new beacon announcement on this new band.

As soon as you QSY the Beacon enable button will show you, it usually starts with a 10 sec countdown, as long as it doesn't sense the freq is busy.
