On
Bob and all,
One problem is that you are using '468/fMhz' to compute the length of a
half wavelength. That is the common 'cutting formula' which includes an
end-effect factor of about 5% which reduces the length of a half wave
radiator. An actual half wavelength is longer.
The actual
Hopefully that we will remember that the DSP filter skirts are steeper
than the crystal filter skirts, so judicious use of the HiCut and LoCut
will provide us with a better passband than narrow roofing filters.
What the roofing filters will do is keep the receiver from reducing the
hardware
Since WRTC operators are already considered top-notch, I would interpret
that data as indicating almost half of the rigs used by top operators
are the Elecraft K3/K3S.

Mike,
How much is "slightly"? If it is only a few Hz, you can change the
offset for the filter a few Hz above and below that printed on the
filter label.

Actually it addresses link coupled tuners that with a tuned to resonance

placed equally out from center on the both coils. The center of the two
coils is common (ground), and unbalanced loads can be fed between the

The XG3 is a fine and easy to use tool. It is useful for a lot more
than just calibrating the S-meter. When used with the XG3 Utility, it
can serve as a full function signal generator with sweep capability.
Yes, the output is a square wave, but as soon as the signal is fed into

HI RFI means the sensor on the RX antenna input is seeing a high level
of RF. If you are operating into an antenna, switch to a dummy load
while you are troubleshooting. It just might be a quirk of your setup,
and if you have no RX Antenna connected, it could be a troubleshooting
I was also 16 in 1956, and do remember trying a few antennas. I had a 3
half waves in phase antenna for 40 meters, and it did the job nicely,
but my first antenna was a 40 meter dipole fed with 75 ohm parallel
feedline. It worked fine with my homebrew 75 watt 6146 transmitter with

Yes, much of the world is shut down, including Elecraft where employees
are under a shelter-in-place directive. Many are working from home, so

I have a gallon of it, but I am hoarding it for my own use.

You said you have sufficient audio, but please look at the ALC meter and
tell us whether or not you have 4 bars solid with the 5th flashing
during transmit. That is proof of sufficient audio.
Have you tried setting a different tone (say 915Hz) in both MMTTY and
the K3?

The true answer to your question can only be had after the
shelter-in-place directive at Elecraft has been removed. Many of the
staff are working at home with only a few at the office location.

Lou,
If FedEx required a signature, I can guess at the problem. Everyone at
Elecraft who can work remotely are observing a shelter-in-place
directive. That would include the front office folks and support and
anyone else who can work remotely.
UPS or USPS shipping may be the best choice
