[Elecraft] Use of K3 Antenna Tuner to match amplifier input

Hi Lance,

Once you have manually tuned the K3 into your TE amp usnig the K3's ATU 
TUNE button, any other time you transmit into it using the PTT the ATU 
will be always be in-line and tuned to the load. It will always reset to 
the last tuned ATU value when you are on 6M. So I'd recommend 
pre-setting the ATU tuning by running the TE amp into a dummy load, and 
then use the K3's ATU TUNE button to tune it manually without using the 
external keying sequencers. Then re-hook up your sequencers and run 
normally.

73, Eric
