Re: [Elecraft] P3 cw waterfall

Barry, It's as Fred said, it changes as a function of the "Rate" setting when running in the "Fixed" mode, however it does so as a side-effect of the slower screen refresh rates. I was hoping to be able to dramatically slow the waterfall to the point of it displaying 3 to 4 minutes of traces, but

Re: [Elecraft] P3 cw waterfall

Okay, what I think is tripping me up is the P3 internal waterfall speed IS varying with update rate but the SVGA waterfall speed is not. Barry N1EU On Thu, Dec 10, 2015 at 11:08 PM, Barry N1EU wrote: > Sorry for my dimness, but I've tried Tracking mode and Fixed-Tune >

Re: [Elecraft] P3 cw waterfall

Sorry for my dimness, but I've tried Tracking mode and Fixed-Tune mode, varying the "update rate" and "refresh rate" and I still am not seeing a change in the waterfall speed. Exactly what do I need to do to see a change in the waterfall speed? In PowerSDR, the Update Period (rate) directly and

Re: [Elecraft] P3 cw waterfall

I remember slowing it down when I first got my P3 but with it currently sitting on the shelf, I can't go experiment. I went to Fixed-Tune, and set up several spans in the buttons. I set the averaging to max on the spectrum display and min on the WF, and I run the monochrome WF option. Other

Re: [Elecraft] P3 cw waterfall

Can someone please describe how to simply change the speed of the waterfall? The update rate doesn't change it. Thanks & 73, Barry N1EU __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help:

Re: [Elecraft] P3 cw waterfall

I think it's the REFRESH rate, and I believe it works in only one of the modes -- tracking and fixed-tune -- can't remember which one and my P3 isn't hooked up right now. 73, Fred K6DGW - Northern California Contest Club - CU in the Cal QSO Party 1-2 Oct 2016 - www.cqp.org On 12/9/2015 9:13

[Elecraft] P3 cw waterfall

Is the waterfall speed adjustable? Any brilliant insights on optimal cw waterfall setup gratefully appreciated! I'm an old fan of the cw skimmer waterfall with traces so clear you can easily read the cw dits/dahs. Thanks & 73, Barry N1EU

The P3 can't compete with a computer but it is handy. n4lq On Wed, Dec 9, 2015 at 4:10 PM, Barry N1EU wrote: > Is the waterfall speed adjustable? > > Any brilliant insights on optimal cw waterfall setup gratefully > appreciated! I'm an old fan of the cw skimmer waterfall

Re: [Elecraft] P3 cw waterfall

Noise power is a one-sided distribution, so the average is positive. We don’t have negative noise power. Ideally, it will average to a flat (white) distribution, but what we hear in the aether is not ideal. So we get a display that shows signals and less-random noise/interference. wunder

Re: [Elecraft] P3 cw waterfall

changing the overall rate of the P3 accomplishes this; to truly "slow it down", the rate has to be pretty high, and it gets pretty choppy. On 12/09/2015 10:55 PM, d...@lightstream.net wrote: > I'd like to be able to slow the waterfall down, but I have found no menu > entry that addresses

Re: [Elecraft] P3 cw waterfall

While everyone [but me] likes the look of the color waterfall, you might try selecting the monochrome version in the P3 menu. Guest ops who can actually appreciate the color display have found they can find much weaker signals in the monochrome option. 73, Fred K6DGW - Northern California

I'd like to be able to slow the waterfall down, but I have found no menu entry that addresses waterfall speed for either the P3 or the SVGA. Is there really a way to do this? 73, Dale WA8SRA > On Wed,12/9/2015 1:10 PM, Barry N1EU wrote: >> Is the waterfall speed adjustable? > > Sure. > ... and
