[Elecraft] New KX2 No Transmit

[Matt Zilmer]

Hi George,

You should check the two RF cables to make sure they're seated. There is 
one cable from the ATU to the RF board (two-pin connector at the RF 
board), and another from the BNC socket to the ATU.  Both of these need 
to be seated in order for the KX2 to work.  The 25.4:1 SWR indication 
usually means the BNC to ATU cable isn't seated, but I would check both.

73!
