[Elecraft] driving external PA with K2

[Lee Buller]

Mike,
 
You already have all the info you need, but I would like to say you will need no ALC at all.  If you keep the rig linear and not over drive the amp...there is no need for ALC.  This feature is kind of a left over from when tubes were tubes and men were men (sorry Ladies, trying to make a bad pun)  Of course, you will not over drive a typical amp with 15 watt of mighty mojo.  Now, if you have a KPA100, that is a different story altogther, but I do not want to digress.  The main point here is keep the rig linear and do not over drive the amp.
 
Have fun building the keying interface.  Works like a champ.
