Please be aware that the transmit current drawn by the K3 depends significantly on the band. On some bands, my K3 draws upwards of 20 amps. 73, Paul W8TM __ 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
Re: [Elecraft] K3, A calibration question
At 100 watts according to the K3, with 12.6 vdc (drops down from 13.8 vdc with key down CW) I get 19.5 adc according to the Hamsource EZ-meter. - Chuck, KE9UW -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-A-calibration-question-tp7567680p7567704.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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3, A calibration question
(Sorry Don, the first one got sent to you instead of the user group) Thanks Don, and Fred AE6QL, Your answers suggest it has it's own regulation built in, which I didn't want to assume. So, I should be able to ignore my key down voltage for this question. (I do intend to beef up my wire gauge.) My K3 shows 15.4 amps at key down in CW at 100 watts with a P3 attached. A dummy load was used. How does that compare with your K3's, please?

Re: [Elecraft] K3, A calibration question
Rich I'm not sure which calibration you are referring too but as long as you stay with the specified input voltage range, all calibration will not change. 73, Fred AE6QL -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Richard Fjeld Sent: Tuesday, December 25, 2012 1:00 PM To: elecraft posting Subject: [Elecraft] K3, A calibration question How much voltage adjustment change can be made to a power supply without the need to re-calibrate a K3?
