[Elecraft] KXPA100 ON light flashing

[Barry Keith Middleton]

I am hoping I can find out a problem I have with my KXPA100 amp and 
KXAT100. The "on" LED

is flashing every 4 seconds. Also when connected to the KX3 the menu 
item ATU DATA is replaced

by 2 horizontal bars and a beep tone. Disconnect the PA and the KX3 
shows the correct menu item.

  I have checked everything and other to the faults listed, appears to 
be working correctly.

     Never sold it, glad I kept it.
