[Elecraft] Wattmeter for K3s Calibration

[Don Wilhelm]

Clay,

An LP-100A calibrated to N8LP's NIST traceable standards is about the 
best you are going to find at a price that is palatable to most hams.  
Used in conjunction with a precision 50 ohm dummy load, the calibration 
results will be better than most other wattmeters.
The LP-100A.  I have one at the workbench that serves as the secondary 
standard for all my other wattmeters.  With NIST tracable calibration 
it's accuracy is typically 3% of the reading.

The Elecraft W2 is also good for that task and should be sufficiently 
accurate with its +/- 0.5dB Accuracy specification.

73,
