[Elecraft] Future KX3/KX2 accessories?

[Matt Zilmer]

Hi Walter,

In the K3S, we could move the KIO3B digital electronics to the upper 
section of the main board, far away from the RF board.  The main board 
is also a multi-layer type, so we could sandwich most of the noisy 
digital signals between signal ground planes, shielding them pretty 
effectively.  This solved the problem of digital noise getting into the 
K3S rx.  In the KX radios, digital noise would be in close proximity RF 
boards, so that opportunity is not available to us.

73,
