K4 Second RX and Transverters

I have sent this question to Elecraft support a few times over the last few weeks without a response, so I am giving it a try here.

If I have a basic K4 and a 2M transverter attached, will I be able to monitor 6M or any other internal band off of the single main antenna port and also have a 2M transverter frequency on the 2nd RX? Or is the transverter considered a second antenna and would require the K4D with he second RX path to have the two bands at the same time? The transverter would use the 10M IF, but I am not sure how the pathing works if the transverter port would be an either or with the main antenna without a K4D.

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.
