The value of SWR doesn't really inform us about the load impedance, line
current or line voltage conditions existing.
In the case of a 1.5:1 SWR, the load Z is 75 ohms, with a power of 500
watts the line current is 2.58 amps with a voltage of 193.6 volts.
At the same time a 1.5:1 SWR, the
"The Elecraft KPA500 amplifier also works efficiently into a load SWR of 1.5:1"
Any such claim is at best misleading. There may be some 1.5:1 loads that that
the KPA500 will be happy with but there are other 1.5:1 loads that it will
object to, to the point of giving multiple PA DISS faults.
Dave, yes my question was “do the VSWR Thresholds work when the KAT500 is in
the Bypass mode” and the answer was No, they do not. There are workarounds of
course but the question was specifically when the KAT500 had been placed in the
Bypass mode with the front panel button. The manual did

Thanks for the update and glad to hear that your
Dick from Elecraft answered my question. The short answer to my question was
“no”.
To answer your question, yes the key line interrupt is set for 3.0:1 as it
should be.

To confirm, is your SWR 3.0:1 or
When the KAT500 is powered on but in the Bypass mode will it still open the key
line to the KPA500 at the preset level (3.0:1 in my case) if the load suddenly
goes above 3:1?
The situation is a remote autotuner connected to a 33’ vertical that I use for
bands that I do not have a resonant
