[Elecraft] KAT-500 Bypass SWR seems wrong

[Don Wilhelm]

Harv,

Have you set those antennas to Bypass using KAT500 Utility?

If you have done that, then you may need calibration on the KAT500 
wattmeter.

If you have not set those antennas to bypass in KAT500 Utility, you are 
likely to see what you are observing.
