One aspect of the LP Pan/PowerSDR-IF combination that hasn't been mentioned is that in addition to serving as a panadapter, PowerSDR-IF is a complete receiver, totally independent of any settings on the K3 itself other than the operating frequency. The LP Pan I/Q demodulator obtains its sample from the K3's 1st IF, which is about 200 kHz wide. PowerSDR-IF includes filters, AGC and demodulators (implemented in software) to support LSB, USB, AM, Synchronous AM, etc. The AM audio quality is superior to that of the K3, because there's no roofing filter in front of the demodulator. So if you are looking for a second receiver to use with your K3 or are looking for the ability to utilize a bandwidth far wider than what's possible with the K3 itself, the LP Pan/PowerSDR-IF combination will do that for you.
However, keep in mind that there's a cost associated with this flexibility, namely that your PC must have a dual-core CPU to run PowerSDR-IF successfully, and you'll need a high quality, wideband soundcard. Also, with 200 kHz bandwidth in front of the LP Pan I/Q demodulator, this greatly increases the chances that the demodulator and/or the sound card will be overloaded by very strong signals, creating serious intermodulation distortion. Like any technical solutions, it has its pluses and minuses.

Perhaps they are two versions of the same thing, maybe they are meeting two different needs. I'd be interested in hearing some comments from folks who have tried both. How do they compare? I don't think this is a question of which one is "better" as "better" is going to be defined by your operating style and needs. Just tell us how they're different and what features of each you like or not and why.
