Keep in mind that I've powered down my K3 many, many times by pulling the plug, not hitting the POWER button, with no problems whatsoever.
That's why I asked Wayne about it when the issue came up before and he said that it is *possible* for data to be corrupted *if* a write process is going on when power is pulled. Data writes happen in response to many things. One of the engineers would have to list them. But it's obvious that problem doesn't crop of often! One caveat to my experience is that when I "pulled the plug" I had the K3 on the bench in bits, not when I'm operating. It's unlikely I've adjusted any controls or pressed any buttons that might trigger a data write for some time before the power was removed. I'm not losing any sleep over the possibility of a "problem" should I lose mains power suddenly (which happens often in our area). Even if such a power loss happened and caused a data issue, I know I can reload from my pc and be up and running again quickly. It only became an issue when someone who had long been in the habit of simply pulling the "big switch" on his power supply suddenly noticed something odd next time he operated and so I looked into it. I mention it here today for the same reason. It's such an infrequent issue that it's worth knowing about should you experience a power loss and then notice something "funny" about your K3 afterward. The fix is easy and quick. Ron AC7AC -----Original Message----- Joe, Many thanks for your help. I had been toying with the idea of buying a K3 for use at another QTH, but there the mains supply is not 100% reliable. If bad things can happen if the 13.8V supply shuts down as the result of a mains outage, that is serious. 73, Geoff GM4ESD ______________________________________________________________ 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
