[Elecraft] K3-100 question clarification

[PEN4WWZ at aol.com]

Hi Everyone,
 
I omitted in my original post that my manual antenna tuner meter shows  the 
15 watts when pressing the K3's XMIT/Tune button though the amp does not  
respond.
 
"I  have my Ameritron  AL-811 (600 watts) amp connected to this K3/100. I 
find that  the K3  Tune command (XMIT/Tune button set @ 15 watts) does not 
trip 
the   amplifier for tune up purposes though PTT trips it when I push it on  
 
the mic."
 
Thanks  again,
73
