[Elecraft] Waterfall question from a new waterfall guy

[Ryan Scott Bardsley]

Hello, 

I am a very very new KX3 and PX3 owner and have been using this as my portable kit when I travel to NYC. 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 have a naïve question about the waterfall. What exactly are the vertical lines that seem to follow the VFO as I tune around? Are they the resonant frequencies of the KX3? 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. 

Being very new to this functionality... what exactly am I seeing?

I made a short video here: https://youtu.be/v3iwWgsIDok

Many thanks, and I love the chatter about how great a company Elecraft it. I have not had a single issue with my radio and am really happy with my purchase.
