[Elecraft] KAT500 and K3 Powering sequence

[Geoffrey Downs]

Just a clarification. The K3 will initialise properly  when using the DB15 
cable provided, at the time it is switched on, the KAT500 is connected to a 
suitable live power supply. The KAT500 does not actually need to be switched 
on. If both are connected to the same power supply the KAT500 will switch on 
(with LEDs lit up) automatically when the power supply is switched on. The 
K3 will then initialise properly when the POWER button is pushed, even if by 
that time you have switched off the KAT500 (no LEDs lit up).

The language of the KAT500 manual is correct if perhaps in need of a little 
unpacking. It says "you must apply power to the KAT500 before turning the K3 
on."
