[Elecraft] Accurate QRP Wattmeters?

[Chuck Gehring]

The Elecraft Mini-Module DL1 Dummy Load has test points that allow you to
use a DMM to measure out put.  I can't imagine anything in that price range
being more accurate

Subject: [Elecraft] Accurate QRP Wattmeters?


Hello List,
I've posted my question on QRP-L and here as well- since I will be building
a KX-1.
I am looking for good ways to measure power output from my KX-1 while I am
building it.
What first came to mind was to set up my Tek 492 analyzer on a 2 dB scale
and then use
a 30 or 40 watt (high power) attenuator to measure CW power.  I have several
Bird 43's
but have never seen Bird slugs for QRP LF, MF or HF.  I think a competing
company may
have a through wattmeter with HF but I forget the lowest scale of that one.
I have read
the E-Ham reviews for the Oak Hills QRP wattmeter-  300 Khz to 54 MHz and
100mW, 1W and 10W
scales- still thinking over the reviews.

Comments on the accuracy of using the Tek 492 method, and on other accurate
wattmeter options?
