[Elecraft] KX1: need some help...

[Don Wilhelm]

Tom,

If U6 is getting hot, check for a short to ground at pin 1 or pin 2.  
Both these pins must not have a DC path to ground.  The DC voltage on 
both pins 1 and 2 should be close to 1.4 volts.  You can reach the pins 
of all the components in the KX1 from the bottom of the board.

73,
