Roy,

I'm keying an Alpha 86 with my K2.  Obviously it's not the same, but it's 
similar.  There is enough time between the activation of the K2's amp keying 
circuit (which is all solid-state and follows the 8r line) and the appearance of 
RF to allow me to key the Alpha from the K2 with no problems.  Actually, the 
only thing that seems different to me when running the Alpha at 1.5 KW output is 
that various things (resistors in my alarm system, traps in my LF antenna, my 
DSL router) tend to explode in the latter case.
