Hi Dave, I do not have any intention to hijack your mail but I hope you allow me to state again that we should not concede "signal would drop around 12dB when 3 channels were used" as weak signal favorites. By my simple spread sheet calculation, we can achieve 4-3dB degradation range at 5 chan

Hi Bobby, That does work nicely if you prepare for an upcoming DXpedition. But when you come across a DXpedition in progress you want to switch quickly without loosing any information. If you then use Configurations, the software restarts which not only takes time but you also revert to some prev
