[Elecraft] PX3: Possible problem with display

[Don Wilhelm]

Larry,

I suspect hum, buzz, and noise pickup on the RX I/Q cable shield between 
the KX3 and the PX3.
Try "Bonding" - run a heavy wire or strap between the KX3 and the PX3 in 
parallel with the RX I/Q cable.  The shield from old RG-8 coax works well.

73,
