I was playing around with my K3 and MFJ 4225 switching power supply, when I noticed a strange thing. As you increase the power output, the input current rises very quickly. Example: in Receive mode, the K3 was drawing 2 amps. In Transmit mode, CW, SK key down, at 1 watt out, it was drawing 4 amps 5 watts out, it was drawing 5 amps 8 watts out, it was drawing >6 amps 15 watts out, it jumped to 15 amps 30 watts out, it jumped to 20 amps
Didn't want to increase the power anymore, but, this seems excessive to me, anyone else ever notice this? Would appreciate any comments on this matter, 73, Bill, k6mgo -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Transmit-current-drain-tp7260744p7260744.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
