Hi Jeff,

If you're using an external transverter, you'd connect it to the XV IN and XV OUT jacks. Let's say the IF is 28 MHz. You could put one receiver on this IF (with a display automatically translating this to 144 MHz), while the other receiver is on an HF-6 meter band.

A K4D is needed to accomplish this dual-receive/different bands scenario. The two receivers will clearly need to use different antenna inputs, implying two A-to-D converter modules. 

The K4D also has a second full set of band-pass filters, preamps, and attenuators, optimizing performance on both receivers.
