[Elecraft] Feasibility of KPA-1(?)

[Peter Zenker]

David

You only need the 11,5 MHz Xtal Elecraft is using in the standard 2 band
version plus some caps.

Section 1 is equipped with all parts for 80m, LPF datas can be overtaken
from the K1 80m Module

Section 2 is built identical to former section 1 as 40/30m Module.
