Hi Mike, hope you are well !!
You can set defaults. In the logform go to "Log", then "Set" and then the tab for "Defaults". In that tab you could set defaults like, for example, making "RST rcvd" default to 59 for every QSO logged. But LOGic automatically polls the rig and auto-populates many data fields when a QSO is logged so its unclear why "Frequency" or "Mode" would be a default value copied forward for every subsequent QSO when they get auto-populated. Must be more to the story or I'm missing the point (most likely...hihi).
