Yes, that was my mistake (mentally moving the decimal point!) However, several others including me have measured a real parasitic drain of almost 40 mA (38 mA in my case) that is produced by the KPA3. I disconnected the power to the KPA3 at the circuit breaker and the drain dropped to virtually zero.
The measurement was made by placing an ammeter in the positive lead from the power supply. Nothing at all connected to the K3 except for the power cable. It's not an issue to me because I switch off the dc supply when leaving the shack, but there are a significant number of Hams who run from batteries and solar panels even at home. 40 mA can be very significant to them if the rig is left connected to the battery. 73 Ron AC7AC -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Jim Brown Sent: Friday, October 18, 2013 4:52 PM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Current Drain When Off On 10/18/2013 2:57 PM, Ron D'Eau Claire wrote: > That only explains the apparent drain of several amperes Jim noticed. If you're talking about me, the false readings I was getting from the Watts Up meter were in the range of 40 mA, and a Fluke measured 4 mA in the positive lead. There may, however, be something happening on the negative lead that is causing the false readings. I don't have a fixture yet to put a Fluke there. I should do that. 73, Jim K9YC ______________________________________________________________ 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
