Re: [Elecraft] K3 Remote Power On/Off Ron Castro
What Don, W3FPR, Stated is the correct way to handle the power on/off function. Pulling power from the K3 without an orderly shut down is very risky and reloading the firmware and configuration files remotely could prove to be a chore. I use the macro to shut things down. After the shut down I then shut off the power supply. To power up I use a relay with an R/C time constant wired across the 12v power buss. When the power supply powers up this relay bumps pin 8 of the accessory socket with a ground pulse telling the K3 to power up. The pulse timing isn't anything close to critical. All this makes the 12v power control a little messy when dealing with remote control. Problem is, I haven't been able to come up with anything simpler. Some of the remote control program out there will issue the power down command to the K3 when you close the program, but not all of them do this. You still have to deal with powering up the K3.

Re: [Elecraft] K3 Remote Power On/Off
Doesn't the K3 automatically save settings every so often via a timer? So it would only revert to an earlier state if the power fails 'shortly' after making a change.

Re: [Elecraft] K3 Remote Power On/Off
I forgot to add that if you permanently connect the ACC POWER_ON pin to ground, you will not be able to turn the K3 off with the PS0 command. It may glitch to a power off state, but will come back on almost immediately. 73, Don W3FPR -- The K3 (K3S) can also be turned off safely (and store the current settings) by using the PS0 command - see the Programmer's Reference. That command cannot be used to turn it on (there is no power to the K3), so the POWER_ON pin in the ACC connector can be pulled low by an external device. If you simply pull power, the current settings will not be saved, and could result in having to reload the firmware to get it going again. 73, Don W3FPR __ 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 Message delivered to arch...@mail-archive.com

Re: [Elecraft] K3 Remote Power On/Off
How do you save the current settings? I think most of us at some point in our lives have had a power failure while operating. John KK9A Jim Brown jim at audiosystemsgroup.com Mon May 30 21:56:46 EDT 2016 Yes. When you turn the K3 off with its power switch, it writes current conditions to its RAM. When you turn it back on, it loads those settings. When you drop power to the K3, that write doesn't happen, so it comes up with whatever was last saved. __ 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 Message delivered to arch...@mail-archive.com

There are folks at Elecraft who are VERY familiar with the ins and outs of remote operation in general and control of the K3 in particular. Whatever issues you're running in to, they've seen it before and can suggest good options. I heard one of them give a dynamite talk to the Saturday morning tech gathering of the Santa Cruz club a few months ago. Your best bet is to pick their brains on this issue. 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 Message delivered to arch...@mail-archive.com
