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. 73, Bob, N6TV https://bit.ly/Y-BOX On Wed, Jun 10, 2020 at 11:39 AM Peter Dougherty <[email protected]> wrote: > Wake On LAN is not functioning on my KPA-1500 using the remote software.
