My K3s has been in service for several years. Power output has always easily
reached roughly 100 watts.
Now, with:
1. ATU TUNE bypassed
2. Good 50 ohm dummy load
3. W1 in line with the load
4. SWR 1:1
Next:
1. With the PWR control set to show 100 watts on the LCD
It is probably necessary to restate my question with more precision.
1. I have calibrated the K3s using Elecraft K3 Utility
2. I have carefully calibrated the W1 using the DDM method with a good
quality DDM.
3. Comparing the results, I see that the W1 consistently calculates
John,
Thank you for your response.
My original K3s test setup was per the manual: good quality dummy load (not
the DL1 because of its 20 watt upper limit) with the ATU off. My high
quality dummy load does not have a test point.
After reading your results, I decided to take the DL1 as my "truth
Regarding my earlier message, I am guessing that the W1 displays peak power
"out of the box" and I am guessing that the K3 power is average power.
If the above is true, then the K3 is actually showing a higher output power
than, in fact, it is producing.
Until I know, for sure, what is being
Just before Christmas I finished building a K3s/100.
I did the transmitter gain calibration using the Elecraft K3 Utility.
This week, to satisfy my need for rosin fumes, I completed a W1. I carefully
calibrated the W1 using the DMM method (Fluke 189).
Working into a 50 ohm dummy load,
wanted to talk Elecraft with another amateur, but nobody seemed to know.
It just seemed to have appeared one day. More Elecraft MOJO?

Hi Guys,
Please don't misunderstand my original question. (And thanks to all who have

I welcome any ideas.
