[Elecraft] Operating Split with the K2

Thu Apr 3 11:59:01 2003

That'll appear in CW at times too, depending upon what you have just =
done.
The K2 controls power with a "feedback" loop that senses the output =
power
level and compares it to the level that you've requested with the POWER
control.=20

Under certain circumstances the K2 will set the transmit power to =
minimum.
While you are receiving the logic has no way to detect that you have
something above minimum power selected. When you start transmitting, =
there
can be a very short but finite delay while the K2 starts transmitting, =
the
power control logic notes that the power is too low compared to what you
have "requested" with the POWER control, and it brings the power up to =
that
level.=20

It happens very quickly, but a quick operator can get a couple of =
syllables
out (or a dit or dah in CW) before the power control circuitry catches =
up.=20

The same can happen when reducing power. If, for example, you change the
power from 100 watts to 5 watts and hit the key or speak into the mic, =
you
will see a brief surge at 100 watts until the power control reacts and
adjusts the output accordingly.=20

I noticed the lag in the VFO display switching .... and also if I had my =

mouth going the instant I hit the footswitch the stations on the other =
end=20
would come back to "the 8deltadelta".  After a few of these I noticed =
that=20
the wattmeter was not moving until the third syllable of the=20
"kiloeightdeltadelta".

So I started to give the footswitch a half second lead time over the =
mouth=20
and more stations got the kilo.
