[Skimmertalk] Waterfall Sensitivity

[Dave - AB7E]

Crossed neurons (or maybe missing receptors)on my part ... I meant to say "I don't think it is any kind of hardware issue", at least not in my case.

Same here.  I've played a LOT with the trace controls on CW Skimmer and it still doesn't display weak but perfectly readable signals.  I'm feeding the Line Out audio from my K3 into a good quality, low noise sound card (M-Audio 2496), so I don't think it is any kind of software issue.

By the way, I've been using the waterfall from CW Skimmer as a running 12 second visual display of in-band (300 Hz or so) CW signals during contests to visually pick up characters that I missed the first time by ear.  It's a bit clumsy, but it comes in handy enough to make it worthwhile having.  I wrote a simple AutoHotKey macro to pause the CW Skimmer waterfall from the keyboard so I don't have to move my hand to the mouse.

I often observe the same thing. I've had no success trying to adjust
the trace controls to bring up the waterfall sensitivity.
