[Elecraft] [K3] Why is the serial data transfer rate so slow?

[Matt Zilmer]

Some possible answers:

1.  The K3 isn't a networked computer, so Ethernet is out.
2.  USB is way overkill in terms of speed, but would work.  USB can
produce significant amounts of RF noise, depending on the quality of
the cable used.
3.  Even paged Flash writes take a few 10's of mS to execute, plus
each page write needs to be verified.  Raising the transfer rate
wouldn't help much.  I'm sure Wayne buffers incoming data while
executing the Flash write, but clearing the write is probably the
bottleneck to transfer performance.
4.  Single-ended serial is relatively RF-quiet and it's ubiquitous.
Well, at least it *used* to be.
