[Elecraft] New KPA500/KAT500 question

[Dave Cole (NK7Z)]

Thanks Don, that was what I needed to hear on your first post.  After I 
figured out that nothing goes through the P3 from the K3 to the KAT500, 
things made a lot more sense...

What a nice setup I have now...  I will be selling my ALS-1306, and 
Palstar HF-AUTO as a result of getting this little amp...  Three db 
difference is nothing to worry about, so 500 watts is great...  Got a 
chance to use it today on the EU opening on 20...  How nice it is in 
CW...  I have never run full break-in, over the past 50 years of being a 
ham...  Should have tried it long ago!  :)

Thank you for the help!

73s and thanks,
Dave (NK7Z)
