Just order the two cables from Elecraft as it is a special wired and
configured cable. E85046 I doubt seriously if an aftermarket cable
would work.
The manual clearly states "do not use a standard VGA cable!"
The KAT500 manual, page 5, Fig. 1 is the correct configuration for your
application. It requires 2 of the E85046 cables. This is not the time
to be conservative or cut cost corners. You have ~$8500 in radios
depending on this.

Bob:
The AUX cable requirement makes sense. Can you recommend an aftermarket cable?
I’ll need one for the KPA500 and another for the KAT500.
Thanks

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.

Tony, The Config Menu has a Per-Band power setting (PWR SET = PEr bAnd) that
will set the power output depending on the band selected. If you use the Aux
cable between the K3 and KPA500 is is fully automatic and seamless. 73 George

George:
I must be missing something because when I select PER BAND in the config menu,
there's no power setting to set.
It doesn't display the power like TUN PWR does where the tune power is shown
within that menu item so you can adjust it.
I have to order the AUX cable, but in the meantime I'd like to use this setting
with the K3S so any suggestions would be appreciated.
