[Elecraft] Power spike early K3

[Michael Carter]

Hi Mike,

I saw that you had posted a similar question
in January 2023 and had some suggestions
including running the TX Gain calibration, which
you did, but apparently without effect on the
spiking.

There have been numerous reports of
TX power spikes on first dit or first voice sound.
Some found that part of the issue was
inadvertent changes in the TX GAIN settings
when the TX POWER control was set to
precisely 5.0 W or 50 W and the TUNE
button was pressed. One respondent
to the reflector commented on this issue
and how the TX power spiking was eliminated:

One question: does the power spiking upon changing
bands occur when only a 50 ohm dummy load is
attached instead of antenna or an amplifier?  Don't
put anything else in the line between the K3 and
the dummy load, and be sure the internal ATU in
the K3 (if installed) is set to BYPASS.
