Jim,
As a follow up to my post about coax stubs yesterday, Dick, K6KR sent me the
Inrad link below in case you want to buy a book to help you through SO2R
interference. I also did some Googling and found a VERY good and concise
description of the coax stub filters and their implementation in a
nt to have
"dual watch" because you will have defeated every SO2R control box and
software program I know of if both SO2R rigs are on the same band.
Have fun!

Igor,
Looking at the Elecraft website for K3 Mods and application notes, it
says "*About 09/01/09 (RF board Rev H3) and later."
*The serial number is difficult to track because of the difference
between kit-built and factory assembled K3s. The ship date is the most
significant tracking method
Starting what serial numbers please.

That document explains a mod that you should definitely make sure is
