Seeking input on KPA1500 station configurations

[Dave AD6A]

Wayne/Eric,

 

Maybe too late, I know, but I've been thinking about my ideal desk setup for
HF/6m/2m and have come up with the following list of wants for the KPA1500
system:

 

I'd like the KPA1500 power supply consumption to be less than 1W when the PA
is "off".

 

I'd like the power supply to be able to be turned "on" by a single button
push on the front panel of the amplifier (on the desk). That is, the
less-than-1W power supply, via a push-button, operates an AC contactor in
the KPA1500's power supply unit (under the desk) to turn on the main power.

 

I'd like the power supply to be able to provide an extra clean 25A (30A?) at
13.8V via several sets (4?) of 30A Anderson PowerPoles on the back panel so
that I can run my whole HF station (K3s + P3) from just the one KPA1500
power supply and I'd like to be able to turn the power for this extra power
supply on/off from a push button on the front panel of the KPA1500 (on the
desk) or simply have it turn on/off with the main AC power contactor.

 

Other wants (not KPA1500): I'd like Elecraft to make a K3s/P3 matching
stereo speaker that is 17" wide x 4" tall x 10" deep, so that it sits neatly
underneath a K3s/P3 combo. I'm actually making my own right now, but I'd
prefer an Elecraft "branded" one.

 

Thanks for listening!

 

Cheers es 73,

Dave AD6A

Would be good if "remote-on" would be possible as well. Possible options include serial command, a dedicated I/O-line, or control lines of a serial port.

Such a setup could also be a nice basis for remote operation, including dead man switch type setups, power sequencing and so on.

Going a bit outside the scope of the post I'm replying to, such a sequencing could also be useful for a later setup of a KPA1500, and a "headless" box similar to K3/K3S, with a RemoteRig-type control.

Small controller unit to power on both the KPA1500 and the headless box as requested by RemoteRig interface, then operate as normal. Allow controller unit to include a timer, disconnect on lost connectivity to the RemoteRig, etc.

Couple of remote GPIO, to allow for sensors based on users need (someone entered the room? Ambient temperature? Temperature at amp chassis?), and things are starting to look very good for remote users.

My 2 cents.

Drop the RS232 line totally and have only an IP / Lan connection.  This
will solve so many connectivity issues.  With a PC client software, it will
just find the amplifier.

This is what other Amp vendors are now doing and it is litterly plug and
play.

The next K-radio should also be LAN aware.
