You're a lot less likely to get an answer to that question than you
would the answer to whatever question you actually want answered.

Your indignation is completely misplaced. Read the thread title. He's
trying to interface to a KAT500, and last I checked Elecraft makes those.

Elecraft has said that the K4 is supposed to eventually have full remote
capability from a PC or even notebook computer, which from my point of
view would be one of the strong selling points of the rig. However, the
last information I saw on it (I think somebody posted a reply from

I still say it was purely a business decision WHEN THEY MADE IT. Yes,
some parts might be difficult to get now, but when Elecraft offered the
last chance buys they obviously expected to be able to source the
necessary parts or they wouldn't have done so. With Elecraft's

The K3s and the K3 with new synths aren't "dead ends". The great
majority of specs for both rigs are better than the K4 and will be until
the K4HD comes out at three times the price. The K3 and K3s are only
"dead ends" because of a business decision, not a technical one.

That window is closed. Elecraft offered a last time buy of modules for
the K3 and K3s some time ago. They hinted that they might have made a
few extras, but for the most part what you have now is what you (or
someone else) will have forever unless you buy a spare rig for parts.
That's
That's what modular design was supposed to address ... as originally
advertised. Modules being no longer available negates that entirely.

For most other brands you can find a repair center somewhere certified
by the manufacturer. Elecraft has never done that, and now that they no
longer support replacement modules and appear to have significantly
pared down their own repair services, I will pretty much be left high
and dry if
I beleive that's your computer establishing serial contact with your
K3. It won't happen if you aren't connected.
