Consider that support for the legacy products - K2/K1/KX1 and XV

Support is different from availability of the product.

Maybe the best would be to update the Shipping Status ,and other statement of

I posted earlier a question about the support status of K3/K3s and
availablability of parts.
I have not found any definitive statement about that.
I for one love the Elecraft
You must remember that the parts that go in much of this equipment is
supplied by the lowest bidder. If a component can be left out even if
its only a few pennies it will be left out. I was in the service
business and owned a business for over 25 years doing installations. I
was never asked
I use Win4K3suite and com0com and run 6 programs simultaneously into my K3S.
No problem, I'm running Dxbase, LOG4OM, DX4WIN, and AClog at the same time
just trying out to see which one I want to stick with. I've been using
Dxbase since 1988 and it's my favorite but no updates since a long time.
You are correct, as usual. My intent in citing motors, et al.
was that MOST of these devices, especially these days, are
monitored/controlled by potentially offending devices.

A K3(S), as well as almost any other "12V" rig, is prone to increased TX IMD as
the supply voltage is reduced. For FD, with reduced efficiency antennas and no
