[Elecraft] KPA1500 Wake On Lan not working

[Bob Wilson, N6TV]

If needed, the KPA1500 can be remotely powered on and off by momentarily
grounding Pin 8 of the KPA1500 AUX port, however this will not work using
an unmodified KPAK3AUX cable, which has no connection to Pin 8.  However,
this "remote power on" feature is supported by the Y-BOX v2.x
<https://bit.ly/Y-BOX>, when connected to the amp with a straight 15-pin
cable (not the Elecraft KPA3AUX cable), as documented here:

https://www.kkn.net/~n6tv/Y-BOX/Features.html#Remote

However, I believe you have the original Y-BOX, v1.x, which doesn't have
this feature.

So in your case, follow the instructions for modifying the KPAK3AUX cable
to support remote power via a K3 macro, as documented in the section
titled *Using
a Remote Site KPA500 from the Control Site *in the *K3 Remote Owner's
Manual
<ftp://ftp.elecraft.com/K3-Remote/Manuals%20Downloads/K3%20Remote%20Owner's%20Manual%20%20Rev%20D.pdf>*.
However, the macro in the manual has an major error:  it omits the last
semicolon.  The correct macro is documented at the link above.
Electrically, you just have to connect KPAK3AUX cable Pin 11 (DIGOUT1) to
Pin 8 in the female end of the cable (the end that plugs into the amp. AUX
connector).

This assumes you're not using the DIGOUT1 line to activate an external
pre-amp like the Elecraft PR6-10.

As a final note, the KPA1500 won't work properly if you connect all 15 pins
between the K3 ACC and the KPA1500 AUX (same applies to KPA500).  And of
course, *never* connect a VGA monitor cable to any Elecraft connector (way
too many lines shorted to ground).  So your best bet would be to use a
15-pin M/F extension between the Y-BOX and the KPAK3AUX cable (after
modification).  Connect the AUX cable to the amp, and the extension to the
Y-BOX.  Then program the K3 macro as documented in the link above.
