I use this one...14 volts, 4 amps. The plug on it fits the KX3 and the open ckt voltage is 14 vdc exactly.

Like most hams, I have a big box of wall warts, and have tried several different 12 V adaptors with the KX3. They all worked ok for general operation, but I noted that when I added the KXBC3 battery charger option to the KX3, I really needed an honest 13.8 V or higher to fully charge the internal batteries. Most of the warts I tried had outputs less than 13V, and the few that I found that could supply 13.8 V under load had voltages above 15 V with no load. I didn't want to take a chance with these by exceeding the KX3 upper voltage speceven for the short time that it would take for the adaptor voltage to drop. My KX3 current drain numbers are (all at 13.8 V): receive, with backlight: 0.190 A receive while charging batteries: 0.400 A transmit, 5W: 1.04 A transmit, 10W: 1.91 A So, I guess the ideal adaptor would be capable of 2A at 13.8 V to support running the radio with no (or fully discharged) batteries at full power, and would not exceed 15 V with no load. While I'm wishing, it would also be smalland lightweight. Any suggestions? thanks, 73 ed N9EP ______________________________________________________________ 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 ______________________________________________________________ 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
