[Elecraft] Subject: Using the Antenna Tuner in the XPA100

[Wilson Lamb]

Mike, I lived in New England for about 15 years and know I'm not the first to talk to you in direct terms. 
Used to sail in Marblehead and know just how snotty people there can be. 
If you don't find my very useful and concise advice to be "constructive" that's your problem. 
I'm 80 and find the judgements of others less and less interesting, especially when I'm trying to help them. 
It's great you have antenna tuner experience, although it's pretty irrelevant to your question. 
The fact that you would suggest plugging the end of a wire into an automatic tuner AT ALL shows a fundamental misunderstanding of both the wire and the tuner.  The autotune, has a two conductor output and you really have to use both of them!  I suggested some reading topics that would help you understand what you asked about, because it's unlikely anyone here will have time to start from scratch and explain the subject to you. 
  
You say your self that the tuner is built for unbalanced coax, so why ask about end fed wires? 
  
Sure, you'll always get "replies."  How much did they help?   
You'll mote that al the BALUN/UNUN talk involves USING A COAX, TWO CONDUCTOR line on the output of the tuner, NOT plgging a wire into it!  Sounds a lot like what I was trying to tell you! 
  
Sure, you sometimes get away without an earth ground.  That's because the shield of whatever feedline you hook up forms enough counterpoise to handle the current coming back to the chassis of the tuner. 
  
Don't lecture me about ham spirit.  I've likely helped as many hams as you, with GOOD advice. 
I've also been told, in no uncertain terms, that my question really showed that I had reading to do. 
  
Yes, I meant to be a little short but I did not mean to be offensive. 
If you can't deal with the answer, simply ignore it. 
If you think people talking to you about long runs of coax and various coupling means answers your question about end fed wire in your tuner, there's nothing I can do. 
Did you actually think about any of the issues I raised? 
  
My time is very short, because of care I have to give to others, and you are lucky to receive any of it, since I have my own problems to solve. 
This note constitutes the LAST of it that you will receive and I promise the esteemed members of the list that I'm off the subject. 
If you want to destroy a valuable piece of equipment, go for it!
