Good rig, but not so hot using with a computer for SDR.   Time owned: 0 to 3 months
I'll certainly agree with the majority that the KX3 has an excellent receiver. Side by side with my Pro2 it has slightly less white noise and outstanding audio quality. But I don't agree with others that signals just "jump out at you" unless you have the RF gain turned way down. It's a good transceiver, but nothing is magical about it.

Where the KX3 fails is in it's implementation of it's IQ output. To observe and use it as an SDR radio you will learn all about external sound cards, images, torroids, isolators on the IQ output etc. Ask anybody who has owned a Flex-Radio SDR-1000. They know all about the pitfalls of these early SDR rigs. That is why Flex-Radio ceased manufacturing that radio. Direct sampling is what most of the higher quality receivers are using with a simple USB cable to the computer.

Purchase the KX3 for use as a portable radio where it shines and you'll be completely happy. But don't expect it to be as good as the current crop of SDR receivers available that use direct sampling. Direct sampling has a far cleaner display than using a sound card.

Product is in production.
