Parts are different from options (assemblies).
Parts from Elecraft will continue to be available as long as the parts
are not obsolete, but the options will not after the stock is exhausted.
The options are assemblies of parts.

In most applications there should be 2 RF chokes. The first RF choke
should be at the antenna feed point, and a 2nd RF choke at the radio. I
find that Jim, K9YC has done excellent work in this regard. This is a
case where many hams and balun companies only go at the problem "half
baked".
Ed explained it quite well. I would add that when a product is
discontinued usually the options, being also considered as product, will
go away as well. This does not imply that repair parts are
discontinued. It is often confusing to users when a product is not
longer available that
I wonder what would happen if you moved the 1:1 choke to the other end of
your feedline (closer to your K3)?

Gary,
I had the same problem. After 3 years, I had to replace the TCXO which had
clearly become defective.
I still need to recalibrate periodically.
I don’t operate HF, so hearing WWV is sometimes difficult. A good way to
calibrate is to have a local, who is dead-on calibrated, send CQ on
To add a little to what Wes said:
The K3 TCXO rest freq is 49,380 KHz. It is a temperature corrected
oscillator so will still drift with radio warm up but less than a
non-compensated oscillator.So best to calibrate after at least
30-minutes warmup. If you have the 100w model K3, there

Yes. Since the K4's signal processing for CW is primarily in the time domain,

One of the potential problems is that the K2 works at 4800 baud, which

There were many counterfeit chips so the patent holders put code in

Are the original synths worth anything?

Mike,
There is one K3S option that you should definitely add to a K3 if you
like CW: the updated synthesizer (2 of them if you have the
subreceiver). It makes a great deal of difference if you send CW at more
than about 30 wpm. There is a QRQ mode that helps, but it has downsides.
Of course
