[Elecraft] Musings on a "K4"

[Bob]

Personally, I'd be happy if I could upgrade my K3 to get rid of all the
clutter on the back panel.  Give me a single Ethernet connection that
allows me rig control, audio in/out, digital modes, IQ out, remote control,
etc.  That would eliminate a ton of wiring.

I use a Icon IC-9100 for VHF/UHF work.  It is a pleasure to move that radio
around.  Power, Antenna, USB are the only things hooked up in the back.  My
K3 on the other hand has:  Paddle in, Key in, audio in, audio out, rig
control, cable for tuner and amp, IF output, FSK input, antenna and power
(10 cables).

The K3 is light, highly portable, and is a performance dream.  It just
requires 50 pounds of cables to attach to everything!

Given the modular approach of the K3, it should be possible swap out the
traditional stuff and supply a digital connection as an option.

By the way, I have never had a RFI issue with a Ethernet USTP network.  All
my computer cables/switches work just fine.  Can't say the same about all
the other connectors and cables.  So going over to a single digital
connection makes for a more robust electromagnetic compatibility situation
as well.  Heck, it could even be WiFi.
