Isao-san,
I also enjoy with the great amp PA-78. It's
quiet and useful, you know.
1) You cannot hear the sound of K2, because it
has only 100-200ms delay time.
2) You can see the green lamp when you locked
out (not selected) both CW and SSB switches, and
90+- seconds after you powered on.
If you have more questions, email me direcrly
without any hesitates.
73,
Sugi JI3KDH
