Joe, I already reset all menu items to default. I've also done the Key Out to PA Key configuration. I've also done the 10 watt exercise, I am getting the asterisk without the underscore and the ~200 watts out. But only when I just tap the paddle. If I string dits together, even at low power the amp shuts off.
The K3 isn't shutting down. I sort of in the camp that it's something internal, however, I've never built one of these. I did get the assembly manual and have looked at some obvious ground connections and all seem in order. Thanks for your thoughts.

Double check amp's menu items and set all to default before test. Remove all cables. Connect dummy load directly to amp. Connect RF in from K3. Connect "Key Out" to "PA Key." Manually select same band on rig and amp. Set K3 for 10 watts drive. Select "OPER." Now, try and key amp. You should see asterisk in amp's display window and around 200 watts out. An asterisk with underscore indicates amp is being inhibited. If amp still fails, I would check all connections internal to the amp. Guess you could also see if the K3 is shutting down... 73, Joe ( AJ8MH-Radio ) On 2/16/2016 9:33 AM, Mike Crownover wrote: 73, Joe ( AJ8MH-Radio ) On 2/16/2016 9:33 AM, Mike Crownover wrote: ______________________________________________________________ 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 Message delivered to a...@gvtc.com ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
