If the K3 were supplied with a stock microphone, rather than leaving it to
the purchaser to potentially make a poor choice and then not bother to
compensate with the equaliser, I believe we wouldn't be reading these
admittedly isolated comments about K3s with thin audio. This has

The OP was more about Phase Noise that is emitted by the Radio.
Here is Wayne's response to the OP.
BTW, Jim's call should be K9YC as Wayne corrected later.

Dear all,
I have a K3/100 and an Acom 2000A and I am wondering how to get the cleanest
signal. The K3 is supplied with 13.8V.
I see several options. Adjusting the K3 to 9W thinking that the KPA100 does
not kick in could be one method. Another one could be adjusting the K3 to
14W thinking that
Hi Kjeld,
One thing I do here is run the input voltage at 14.5V. The K3 can
accept up to 15V, and the 0.5V gives the power supply some margin for
overshoot.
This station is on solar power, so its natural voltage is 13.6V. I
use an N8XJK battery booster to get the 14.5V to the K3. The
Hi Kel,
The K3/100's phase noise and ALC artifacts are so low at all power levels that
you shouldn't need to finesse this. I would select power level based on what
you want to get out of the amp.

That document compares ARRL Lab measurements, all at full power.

Wayne all I can say is wow! I knew the K3 was good but I had no idea it was
that much better. Let's hope the other manufactures adopt the most sincere
form of flattery... they copy the K3. After all that benefits all listeners

reducing the noise from the N8XJK battery booster. The author is
interested in a mobil application and is concerned about direct
noise pickup by the nearby antenna.
