Hello Don,
 
Thanks for your reply.  I am just curious because the output socket using 
twisted wire but the input socket using coaxial jumper.
 
I am still looking for the information about spurious emission and 3rd order 
distortion of KPA500.

TNX & 73,


Johnny VR2XMC

Johnny,

Twisted pair is just as effective as coax, and easier to work with.  I am not 
certain that was the reason for that design, but there is no problem with it.
