[Elecraft] [P3 SVGA] Has anyone seen garbage in the waterfall display?

[dmb at lightstream.net]

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.
