Some suggestings that may be considered for inclusion in a future release of CQ100:
1) By band, establish a separate ‘Calling’ frequency.
2) By band, enable a lookup to see who is connected.
3) A lookup by call sign to see who is connected, and with a single click switch over to that frequency.
4) Establish memories presets with single transfer to that frequency
"if I just want to listen and sand bag" - Your point is understandable, and if we could just get the calling frequencies and the memory presets the that I think would make a lot of CQ100 users very happy.
