[Elecraft] K3 xmit problem

[John R. Lonigro]

Mike:
This is a shot in the dark (I don't even own a K3).  Did you tune the 
rig when you installed the dummy load?  If it is like the K2 (and I 
think it is in this regard), the antenna tuner stays at the settings it 
last made for whatever load was placed on the antenna input.  Putting a 
dummy load on it doesn't guarantee the SWR is 1:1.  You need to tune the 
rig for the dummy load.  Then it should be close to 1:1 if all is 
working properly.

The fact that it seems to work fine with antenna 2 aroused my suspicion 
that this is the only problem you are facing.

73's and good luck,
