[Elecraft] Measuring SWR (Long)

[Fred Jensen]

Why does everyone seem to think all the secret, hollow mountains are in 
Nevada?  I know of one in Colorado and another in Virginia.  Umm ... 
maybe that's in West Virginia, not sure now.  [:-))

>> I chose these scenarios deviously, to illustrate a kind of corner case, but I think you get the idea that errors always exist in any power measurement like SWR. You might say, "But my SuperDuper wattmeter is calibrated by aliens in a metrology lab deep inside a secret mountain in Nevada and I would bet my life on it." Great, cool, congratulations. But I'm afraid every last power meter has errors stemming from mismatch, directivity, nonlinearity and drift.
