altosui: Must set radio calibration before radio setting

Setting the radio calibration erases any previous radio setting as
the radio calibration change invalidates any previously computed radio
setting for a specific frequency.

Hence, the radio setting must be configured *after* the radio
calibration value lest it be ignored.
