I don't think it has much if anything to do with the size of Elecraft.
WW2 gear was built with point-to-point wiring and components [e.g.
resistors, capacitors] that were available through the 40's, 50's, 60's,
70's, 80's, and even into the early 90's. My Swan 500C in the late
60's was
Just love pronouncements as the concrete hardens around them! "640

Can't speak to your current or future thinking Gary, but...
The K3 and K4 [and some other non-Elecraft radios too] are near the
physical limits for most of what we consider important today. Not going
to get much better because of that, and who's at the top will depend for

That is only true if DHCP is enabled in the router [it almost always is
in home situations], AND the device you're connecting is configured to

Or perhaps OOKPWM? That was the only available modulating technique for
spark transmitters. For all it's apparent simplicity, it is still
possible to create a rotten signal, and it is notoriously difficult to
decode ... unless you're a human being.

OK, now this is starting to make sense. Jim’s K3 has a KIO3, not the newer
