Changing Frequency Using the VFO panel

Modifying the frequency in the primary VFO and striking the Enter key will set the radio's primary VFO to the specified frequency.Modifying the frequency in the secondary VFO (if visible) and striking the Enter key will set the radio's secondary VFO to the specified frequency.

The ▲ and ▼ buttons to the left of the primary VFO's frequency display will shift your radio up or down one band; if the Ham Bands box is checked, these buttons sequence among the ham bands from 160m to 2m, otherwise these buttons shift up or down 1 MHz. If you click and hold these buttons, they will autorepeat at a rate governed by the VFO Autorepeat Rate slider.
