[Elecraft] How Accurate of 50-Ohm Dummy Load for 50 Watt TX Gain Calibration?

[Tony Estep]

Phil,

Your 20-watt dummy load will work with the automated procedure, and it is
the best one because if the SWR is over some threshold you'll get a "SWR
too high, calibration failed" message.

The 20-watt load is very unlikely to overheat; my 10-watt load did not
overheat, because the 50-watt transmissions are short. However, the sure
way to make it work is to cool it with a sandwich bag filled with crushed
ice.

The automated version only takes a minute or so to do and it only has to be
done once.

If you are unsure, you can follow Wayne's advice and do it manually,
allowing some time to cool in between each band.
