[Elecraft] Reducing K2 power below 1 watt (QRPp)

I have a friend that built something where he works as low as .05w and lower
using WSPR most of the time. He is an extreme QRP op and has been so for
some time. In fact he was the person that steered me to the Oak Hills
Research WM-2 QRP wattmeter one of very few accurate at very low power QRP
levels.

 My Elecraft and Alpha wattmeter's will read QRP levels but not as low as it
will and it's a fun kit to build. He uses a K2 and I do a lot of the time
but now use my KX3 for everything except digital modes like WSPR.

73,
Fred/N0AZZ

I never tried to go that low, but I thought it went down to zero. Have you
tried putting a watt meter on it?
