[Elecraft] [K3] autotuner for K3 with AL-811 amp (KAT500 or other) / random wire antenna

[Rick Bates, WA6NHC]

Same thing here except my doublet is a stealthy Extended Double Zepp cut for 80 meters (340' long).  Works on all bands (6 countries on 160; 200+ countries on the other bands)... 100' of 450 ohm line, 4:1 common mode choke, some coax and the K line is happy.  I just wish the oaks were taller, 30' above dirt just isn't enough height.
