Folks,
I have a K2 and have built a Communication Concepts 100 watt external amp.
Until now I have been using individual LPFs but have a Packer LPF-100 that I
was using with the MOBO project and I would like to use it for the K2/CC combo.
The easiest bandswitching is with a 6-pole switch.
Easiest way to do it would be using the KRC2 .. and someone was
selling one on the list recently ;)
