[Elecraft] Extra Protection For KPA500?

[Bob McGraw K4TAX]

Tony et al:

Go to the K3S  CONFIG menu and PWR SET.  Set the value to PER BAND.  
Then exit this menu by pressing MENU/CONFIG.  There IS NO value to set 
at this point.   Then with the KPA500 on and in OPER mode, while in RX, 
set the PWR value on the K3S to 20 watts or what ever power you wish to 
drive the amp with for that band. That is saved for that mode and 
band.   Then on to the next band.

When the KPA500 is in STBY mode the power value is what is set on the 
K3S for barefoot operation.  When the KPA500 is switched to OPER then 
the power value is what you have set for that mode and band.   This does 
require the KPA500 to communicate with the AUX cable.   See page 12 Fig 
3 of the KPA500 manual for the configuration.

If you have the K3S, the KPA500 and the KAT500, then see page 5of the 
KAT500 manual, Fig 1 for the correct cables and configuration.

As they say, it is all in the manuals.
