Thanks for the info Bob, and it’s reassuring to see that the KX3 has protection for over voltage. One caveat with this PSU - I just tried to insert the DC plug from this PSU to the KX3, and I see it is too large for the KX3. Not a big deal, I will just cut it off and fit the correct size DC plug

Someone on this reflector suggested a power supply off eBay, that could be used with the KX3 about 2 months ago. It is intended for Toshiba laptops. So I bought one, this is the one… http://www.ebay.com/itm/15V-5A-AC-Adapter-Charger-Power-Supply-For-Toshiba-Tecra-A6-A7-A8-A9-A10-Laptop-/381356162365?hash=item58ca993d3d:g:Yk0AAOSwMmBVxX22 <http://www.ebay.com/itm/15V-5A-AC-Adapter-Charger-Power-Supply-For-Toshiba-Tecra-A6-A7-A8-A9-A10-Laptop-/381356162365?hash=item58ca993d3d:g:Yk0AAOSwMmBVxX22> It terminates in the right plug for the KX3 and is rated at 15 volts at max 5 amps, and only sells for $ 7.79 including free shipping from Hong Kong. Anyway, it is cheap as chips so I bought one, and it arrived today. I hooked up to a volt meter and see it is 15.4 volts. I know it is better for TX IMD to have higher voltage supplied to the KX3 rather than a voltage too low, but I am concerned that 15.4 volts may be too much for the KX3. I see in the KX3 manual specs, that recommended supply voltage is 8 - 15 volts. I would hate to hurt my KX3 with over voltage……anyone know if there would be any short or long term problems with running 15.4 volts to the KX3 ? It is just slightly above the maximum recommended supply voltage 73 John, ZS5J. ______________________________________________________________ -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-power-supply-tp7612732p7612736.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
