[Elecraft] K2 Antenna Tolerance

[Ron D'Eau Claire]

Tom, the Owner's manual says " 2:1 or better SWR recommended; will survive
operation
into high SWR."

The current demanded by the finals (and so the K2 overall) will increase as
the SWR goes up. A programmable transmit current limit will display HI CUR
on the LCD if you exceed it. Typically the current limit is set for 3A and
the normal transmit current is 1.5A to 2A. A too-high SWR will cause the HI
CUR to appear. 

If that happens to you due to the SWR being a bit too high, you can protect
the K2 finals by reducing the power.

I've just finished my K2 bare bones, and would like to get on the air. What
SWR will the finals tolerate without harm? I'm using a ground mounted trap
vertical
