[Elecraft] KPA-1500 questions and low pass filters

[Hisashi T Fujinaka]

I had similar questions.

Use a cable with RCA jacks to connect the K3/K3S rear panel 12V DC OUT
RCA connector to the KPA1500 REM RCA connector to wake it up. You'll
still need something to change OPERATE/STANDBY on the KPA1500, but I
just use the KPA1500 utility over Ethernet.

The power output on your K3/K3S will be different when you have the amp
in OPERATE or STANDBY.
