[Elecraft] Future KX3/KX2 accessories?

[Walter Underwood]

Thanks for confirming my guess.

I remain amazed that serial connections are used so much in amateur radio. Outside of amateur radio, I’ve used RS-232 connections once since the early 1990’s. In 2002, I connected a console to an HP-UX to rebuild the kernel and get it on our net. I threw away all my RS-232 connector building stuff a decade ago. Then I got into amateur radio.

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.
