[Elecraft] PX3 lines - no radio attached

[David Davis]

This might be an obvious question for some of you so I am hoping I can 
get a quick answer. However, I am very new to this type of equipment and 
have no idea if this is normal or not.

I have a brand new PX3 panadapter, even when there is no radio attached 
to the unit there are four small signal spikes and nearly solid lines on 
the waterfall below. There is one line below each spike. I also see 
these even when a radio is attached and was just wondering if these are 
normal or if there is a way to make them go away.

Thank you in advance for any answers.
