[Elecraft] KPA500 RF output wiring

[Johnny Siu]

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,

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.
