Yes.  There are at least three methods to power the KPA1500 ON/OF
independently without using the REM jack on the back of KPA1500, assuming
you leave the rocker switch on the back of the separate KPA1500 power
supply in the ON position:

   1. Connect the KPA1500 to a PC via USB cable.  Use the KPA1500 Utility
   (running on a local PC) to power the amp. on and off.  The KPA1500
   Remote Software
    also
   has this capability.
   -or-
   2. Momentarily ground Pin 8 of the KPA1500 AUX connector.  This is
   easily accomplished using an S-BOX  or S-BOX-USB
   and a simple program to pulse the DTR or RTS pin of a real or virtual
   serial port, or you can build an equivalent circuit using a resistor and
   NPN transistor (same technique that is used by RemoteHams software to power
   up a K3 remotely with no RemoteRig box required).  A KPAK3AUX cable cannot
   be used (no connection on Pin 8).
   3. Use a Y-BOX v2.1  which can connect DIGOUT 1
   (Pin 11) to the amplifier PIn 8, and a K3 Macro, as described in detail
   here .

For example i want to turn on K3, but want to have KPA1500 off, is there
> any way to do that?

Yes.  See above.

Re: [Elecraft] Remote On/Off KPA-1500

[Dick Dievendorff]

The programming reference has an ^os command to do this.  The KPA1500 Utility 
Operate tab and KPA1500 Remote programs use this command.

Re: [Elecraft] Remote On/Off KPA-1500

[Dick Dievendorff]

1) send a serial command ^on1 via the USB port.  This is what the KPA1500 
Utility does.  The amp can process a few commands like this when “off”. The 
KPA1500 Remote program can also do this, via the USB connector. ^on0 turns the 
amp off.

2) supply 12v DC to a rear panel RCA connector. This can be used with a K3 to 
power the amp on with the K3, but any source of 12v will do.

3) pull down (ground) pin 8 on the ACC connector.  Pull it down briefly.

4) send a Wake on LAN “magic packet” via the Ethernet connector.  WoL must be 
enabled with a menu option.The KPA1500 Remote program does this when 
connected to the amp via Ethernet.

Re: [Elecraft] Remote On/Off KPA-1500

Also, is there an easy way to also toggle the amp between operate and standby? 
Would be nice to write an app for a Smartphone, either Apple or Android (I 
carry both).

Re: [Elecraft] Remote On/Off KPA-1500

[Jorge Diez - CX6VM]

hello

what are the diferent ways to turn KPA1500´s on/off remotely?

Is there any way to turn it on/off alone, with no need to turn on/off the
K3?

For example i want to turn on K3, but want to have KPA1500 off, is there
any way to do that?

thanks,

Re: [Elecraft] Remote On/Off KPA-1500 - How I do it

[Rich Yost via Elecraft]

 I use a 12v power cube plugged into a Network Power Switch.This is how I turn 
my 6500 on remotely also.
Its a 4 outlet internet switch, so I use it turn apply 12v to the REMOTE jack 
and turn on the KPA-1500.

Some do this with an RCA cable from the K3 rear panel 12v line to the amp REM 
connector. The amp turns on and off with the rig.  Current draw is minimal; you 
can also use the same K3 12v to power your P3.
