Re: [Elecraft] [P3 SVGA] Has anyone seen garbage in the waterfall display?
Hello Hisashi, >From the picture you sent, I believe you also need to adjust the SVGA "bias" >way back. The adjustment is accessed from the SVGA menu. I had the same >waterfall screen appearance until I dropped the bias back to around "2." 73, Bill - W0BBI __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] [P3 SVGA] Has anyone seen garbage in the waterfall display?
Aha. Things look quite different on both monitors, and as George Danner pointed out, SVGA bias can be turned down to amke the display on the SVGA look the same as on the internal monitor. Default is 9.9, I think, and I turned it down to 1.2 at his suggestion. Of course, my REF LVL needed adjusting as well. Thanks for the help.

Re: [Elecraft] [P3 SVGA] Has anyone seen garbage in the waterfall display?
Hello Hisashi, It looks like you have a very high noise level, or, you never ran the level calibration for the P3. Other than a few blips on the right half of the screen, I don't see any signals, so I wouldn't expect to see much of anything in the waterfall either. That said, you can put the waterfall into a more usable range by simply adjusting the "REF LVL" (on front panel of P3) downward until the bottom edges of the noise spikes in your spectrum display baseline are just hitting the bottom of the diving line between the spectrum display and the waterfall display. That will produce the detail you're looking for in the waterfal display. 73, Dale WA8SRA > I just got my P3 SVGA card and it's just showing video noise in the > waterfall.
