40 Meter Waterfall Ghost

I received my shiny new 6400 this week and I've been busy tackling the Flex-newbie learning curve. I'm seeing a strange "ghost image" on the 40-meter waterfall. I'm listening to a QSO on 7.192. At about 7.330, there's a vertical stripe that looks like a modulated audio scope trace (for lack of a better description). If I move to another 40 meter frequency, the "ghost" moves down the dial too. Before I embarass myself by submitting a trouble ticket, is there anything "dumb" I might be doing do cause such distortion. The problem does not appear on any other band (that I've seen - yet). I'm attaching a YouTube video since I'm sure my description has everyone scratching their heads... thanks in advance for any advice.

John, this looks like you have a power supply problem. The supply is generating RFI that only shows up on 40 meters.
When you modulate, the RFI follows your voice. I suggest you try a different supply.
I have found wall wart supply's that generate "ghosts" but none that moved with my modulation.
If you don't find relief with another supply, Flex is the best at helping out.
