PX3 displaying artifacts...

[Elecraft mailing list]

I have tried this with two KX3’s with the same result.

 

When connecting a PX3 to a KX3 and there is no antenna, the flat signal on the PX3 has some artifacts. The highest being where the KX3 unit is placed and then 2 to 3 on each side symmetrically of decreasing amplitude. This means that when you scroll the VFO for a signal it appears as if you are always on a signal!

Usinbg the same PX3 on another KX3 I get the same.

 

Unless KX3 rigs are sensitive to some local noise (compared with a K3 where there are no artifacts on a P3) then it may be the PX3 itself, but what is the adjustment to cancel this? Any clues or suggestions would be appreciated.

There is artifact(s) that appear on PX3 but they are really low strength and will disappear as you see real signals.

How close is the PX3 to your PS? I know my unit has spikes from the PS placement. Try separating or running off of a battery, if available.
