[Elecraft] Waterfall question from a new waterfall guy

[gt-i at gmx.net]

Ryan,
The traces I can see are signals of other stations. The KX3 (as any 
other SDR) has a limited bandwidth to display, so it will shift the 
display window while your are tunining out of your displayed frequency 
window. So, if the traces you refere to depend on the tuning speed of 
your VFO movements, we might talking about the same thing.

You may want to tweak your display a bit: change your vertical scale a 
bit higher to see the signals starting from the noise floor up to their 
peaks.

Happy waterfalling!

I spend most of my life traveling in hotels, so I can't say I have really reached out to the world yet, but it certainly makes the stay a bit more fun. The KX3 and PX3 combo has been wonderful to bring on the train, setup at the hotel, and fiddle around with after work.

I am running both units on a battery, so I can't imagine it is noise from a wall wart. But I seem to see the same thing when operating at home. On the PX3, I see the green freq/bandwidth bar move when I rotate the VFO on the KX3. But the vertical traces seem to follow along with that.
