I'd like to echo the original post. Trying to find a window to call CQ has been nearly impossible for the past two days on 20 meters. The calling frequency is blocked with beacon contacts. Forget the math part, here in the US in the afternoon it's really unusable. If the objective is for chat, the experience is not lost by either moving the beacon slot or by doing the same with the beacons as is now done with a CQ, i.e., forcing a move after the initial connect.
