Re: [Elecraft] K3 Current Drain When Off
When I tried measuring in the negative lead, I found zero amps. The problem is that the grounding system in my station setup bypasses the negative lead, probably in several ways, letting me power the K3 up with no connection to the negative power supply lead at all.

[Elecraft] KX3 turn on Dual RX in menu
I went to MENU. DUAL RX is OFF. Both a and b vfo are within 10 kc on 40 M SSB How to I change OFF to AUTO? I have never tried this before. Manual just says do it. Narrow filter is installed but should be disabled by SSB mode. I need the magic switch? Direct please so I do not have to wait for the Digest.

[Elecraft] Solar update need information on KPA500
I am looking to upgrade my solar panels and battery bank to be able to order and use a kpa500 amp. I wanted to know if anyone had one and a kil-a-watt meter if they could take some readings for me? I wanted to know how many watts it pulls in off, stand-by, operate, and at full power out. Thank you I sure appreciate anyone helping me. I want to plan ahead and not find out in real world and possibly be out of power one night. lol Thanks Gerald - KC6CNN - Gerald K2 # 5486 K3 # 6254 KX3 # 757 -- View this message in context: http://elecraft.365791.n2.nabble.com/Solar-update-need-information-on-KPA500-tp757.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 Current Drain When Off
That only explains the apparent drain of several amperes Jim noticed. There is still a static drain of nearly 40 mA when the K3 is "off". That was measured by at last two or three of us. I used a DMMs inserted in the power supply line. The 38 mA parasitic drain on mine is almost entirely to the KPA3 module. It is always connected to the dc input. Current to it does not flow through the dc control circuitry operated by the K3's Power switch. Disconnecting the KPA3 at the circuit breaker stopped the parasitic current flow. Wayne reported, "Every K3 we've tested drops to a very small number of milliamps of current drain when off." I'm not sure whether the 38 mA I measure fits in that "small number of milliamps" criteria, but it's never been an issue for me since I turn off the 13.8 V power supply when I leave the shack. 73 Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Ralph Parker Sent: Friday, October 18, 2013 12:41 PM To: Elecraft@mailman.qth.net Subject: Re: [Elecraft] K3 Current Drain When Off >>I would suspect a display problem with the Watts Up ... >I pulled out my Fluke and an adapter I had made years ago for a current >probe and measured both radios.
