[SOLVED] Can You Hear the Difference? K4D vs Flex 8600 in Weak CW [SOLVED]

-Edit. Thanks to the help from the FB group I was able to get the issue worked out! In this video I put the Flex 8600 and Elecraft K4D head-to-head on weak signal CW. My goal was to keep everything as fair as possible: same brand coax, same antenna, switched with an Alpha Delta switch, and filters set the same on both radios. I'm running QK4 software for the K4D and SmartSDR on macOS for the Flex. In my opinion, with the exact setup you see here, the K4D pulls CW out of the noise noticeably better than the Flex 8600 — and I'm genuinely curious why. Here's where I need your help: I'm very familiar with the K4D but still learning the Flex 8600, so I have to wonder what I might be missing on the Flex side. Wrong setting? Something in SmartSDR I've overlooked? If you spot something obvious, please drop a comment below — I'd love to get the Flex performing at its best. 73, Mike KF5O
