The part that confuses me is the mention that "[PowerSDR] fully integrates with the KRX3's main and sub RX frequenciy on its panoramic display".
Thats what it does now. But in order for the KRX3 to actually be adding anything you'd have to be listening to its output with the full K3 filter chain. Cause you're not going to correct the dynamic range problems unless you're doing that. Then I don't see how it could allow you to be more than 192KHz/2 away from your main center freq as you'd have to have two sound cards and two IF outputs in order to pull that off. I guess I don't really see a SubRX adding much to the PowerSDR setup unless you use one RX as a spotter and the other as simply a K3. I think that 2 K3's would be a better setup for that. I see the subRX in the K3 as a way to make the K3 a better unit as a standalone unit. Which I think is one thing that the K3 does really well especially since you can make RTTY/PSK contacts with just a K3 sitting on your desk and nothing else. You can also run it as a contest station for both CW and SSB (once the DVR is out). I find it quite fun how much one can get done without the need to interface it to a computer. Now don't get me wrong I'm a total computer guy and I find it even cooler that while it does all this stuff to not require you to have a computer it also makes is SOOO easy to interface to one when you decide you want to. So I guess all in all color me happy yet still confused as to the KRX3 adding much to a powerSDR setup.
