Re: K2 Power Calibration

[Craig Smith]

I second what Don said about using the Elecraft DL-1 for power measurement.
Recently finished my K2 and found the DL-1 to be invaluable - Everyone
should have one.  I must have used it 10 times already, including today when
I installed the 160 m option.

I put the power vs. voltage formula that comes with the DL-1 into an Excel
spreadsheet and just enter the DC voltage and get an accurate power reading
in seconds.  Have a matrix of power out on each band so I can see if it
changes over time.

Yes, Don converted me a long time ago. I've tried most of the wattmeters for
QRP work and nothing has given me more confidence in what I am measuring
than the DL-1 and an accurate DMM. Less is more.

I put my DL-1 in an Altoids tin and printed a nice convenient chart to go in
the lid. You can see it here and download the Excel spreadsheet used to
generate the chart:

BTW, my K2 gets a lot of use in off-beat projects. It served me well as a
VFO for my Drake boatanchor station. It will soon be keyed with a 1923
Vibroplex Original and receive to a 1920's Western Union Sounder for use on
a couple of American Morse nets. It's good to see all the old stuff playing
so well with a state-of-the-art rig like the K2.
