works fine during low sunspots. I agree Rick. During 2008/2009 we had almost daily openings (both morning and evening) over the pole to Zones 17/18/19/23. Several Zone 17/18 stations (RZ0AF, UA9MA, e

to do is subtract 8-10 dB to get very close to Rob Sherwood's findings. No biggie. The actual IMD difference is ~12 dB which is the difference in noise bandwidth between 3 Hz (spectrum analyzer) and
K8AC: Orion II probably hasn't tried an Orion II. I was an original Orion owner for 4 years and much prefer the K3 for the following reasons: 1. The K3's sub-RX is identical to its Main and close-spa

In my opinion hardware differences are insignificant, especially if you use the Inrad #352 600 Hz roofing filter in the original Orion. The primary difference is firmware. Orion can use v1 or v2 firm

Just to second what others have said, both the Orion and K3 are the best there is when it comes to receiver performance. Each has features I prefer but the basic RX performance is very similar. I als
