[Elecraft] KPA500: birdies on 6m from LCD backlight

[Fred Jensen]

Rarely get on 6m but tried mine and the only birdies I see on my P3 are 
the permanent ones from the wireless company's gear at the top of my 
tower.  LCD brightness = 8, no change turning KPA500 on/off.

There have been various postings in the past about stray signals 
ultimately traced to bad connectors, chassis connections unbonded, and 
bad cables.  You might poke around a little in those departments.  I can 
see the LCD with backlight off but room lights on, however it's really dim.
