Is there anything special about how the K3s dual VFOs work?
There are dual VFOs (A and B), controlled by separate VFO knobs. You can operate SPLIT, as usual, whether there’s a subreceiver or not. The K3’s VFOs can be set to different modes and even different bands. Each VFO also keeps track of its own filter presets (I and II), on a per-mode basis. A “preset” in K3-land is a combination of a crystal filter (selected automatically by the DSP controls) and the DSP settings (SHIFT/WIDTH or HI-CUT/LO-CUT, which can be used interchangeably). Having two presets per-mode/per-VFO allows you to set up the two XFIL/DSP combinations you use most often and quickly toggle between them using the I/II button. There will be an option to link the VFOs (frequency and/or mode and/or band), or make them fully independent. For example, if you allow VFO B to be completely independent of A, you can set it to a different band, perhaps to monitor a calling frequency, while using VFO A for normal ham-band RX/TX. VFO B has its own frequency display, LOCK icon, and (if th

There is an option to link the VFOs (frequency and/or mode and/or band), or make them fully independent. To enable linking HOLD the SUB button for at least half a second. A second HOLD enters Diversity mode if the sub receiver is installed. With link and diversity modes the VFO A knob controls tuning for both VFOs. If you allow VFO B to be completely ind
