[K3] [Elecraft] It have to work better!

[Alexander Ponomarenko]

Priwet Bill,

In original K3 the W16 is monowire (on top of the RF-board),
but if we will analyze the scheme, we can see that W16 must be in the 
screen.
The W16 are near non screen-shielded BP-Filters, and we can see second 
RX-channel on my first web-link:

You can get out monowire W16, and replace to new W16 (behind RF-board in 
our opinion).
You must to use coaxial-cable for W16. I'm used silver-plated 
screen-shielded video-cable from Supra.
