I have a question for the KPA500 owners: I've been reading through the manuals and exchanging some emails with Elecraft support over whether or not a directly connected KPA500 amp can be turned ON/OFF in concert with the K3 it's connected to. It appears this capability doesn't exist however looking through the available I/O I've come up with the following idea;
I see a provision in the KPA500 for a pulsed low input at the KPA's AUX connector pin 8 to turn the amp ON or OFF. For those not using transverters could a K3 menu option be added to pulse low the K3's ACC connector pin 7 (K3 ON) for KPA500 control? If I add a KPA500 to my K3/P3 station I would like to be able to turn all ON/OFF using only the K3's power switch. I realize the KPAUX cable set may not support this idea but aside from that can it work? I'm mostly concerned about the turn OFF command and whether or not it can be made to function as I suggested while the radio is in the process of shutting itself down. If this does work then perhaps we can persuade Wayne to add the option into a future K3 firmware upgrade. 73, Gary N6LRV ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
