[Elecraft] WHY HIGH RF OUTPUT???

[Jim Garland]

Hi Jim,
Sounds to me like you've got a bad slug in your Bird wattmeter. If they're
dropped or jarred they can change calibration significantly.  Also, you
didn't mention the frequency range for the slug. If it's designed for VHF,
it will read high on HF. To me, the numbers you're getting don't sound
plausible. BTW, the correct name of the Bird 43 is "Thruline," not
"Tru-Line".

73,
Jim W8ZR
