[Elecraft] K3 antenna tuner...

[John Ragle]

Van...

     My recent experience with automatic antenna tuners is the 
following: K2 ATU, FLEX 3000 ATU, K3 ATU.  I believe that your proposed 
antenna will be easily handled by the Eledcraft ATU's. You do specify 
that your TX is a K3, but I throw in my experience with the Flex 3000 
ATU for the general readership...I strongly suspect that it would <NOT> 
be satisfactory. My FLEX would not even match a Mosley tribander on 10 
meters, and I had to use an external manual tuner for 15, 10, and 6 
meters with it. The 6 meter antenna was also a Yagi, and I examined both 
the Mosley and the 6 meter beam with my VNA and neither showed an 
unusual mismatch.
