[Elecraft] K3 FD report in high RF (K3 vs Flex 6xxx)

[David Gilbert]

"Maybe it was something with the setup."

That's an understatement.

Running kilowatt-level power on the same band to two antennas only 20 
feet apart is simply crazy.   I don't know what input protection the 
KX3's have, but they almost certainly kicked in and being inherently 
non-linear they would have generated all sorts of high level trash on 
the front end.  It would be interesting to see the math, but I think 
you're lucky you didn't blow the heck out of both front ends in spite of 
the protection.

One rig used the elecraft 500w amp and one used a 1.5kw amp.  The two elecrafts could not operate on the same band at all.  Maybe it was something with the setup.
