[Elecraft] simple(st) panadapter for K3?

[Matt Maguire]

Well, it depends what you mean by the terms "simple" and "cheap".

You need to be able to get IF out -- I think you need a KXV3A modules for that. Then you need an I/Q mixer to provide baseband I/Q signals for sampling by your PC soundcard, the cheapest option probably being a softrock:

A crystal-locked one is fine if you have a crystal close to the K3's IF, or else a Si570 frequency-agile one is more expense but more flexible. You will get some LO leakage out the antenna connection of the softrock, so you probably want to build a buffer amplifier to provide some isolation. Of course, there is more sophisticated high quality SDR hardware available in the marketplace, but of course you pay more. You choose your compromises :-)
