What you experienced is not a bug. Do you turn off your PC by unplugging it?
The K3 has a CPU in it, and in order to clean up and go to a power down state, it needs to be RUNNING to stage itself down. Ever try unloading the groceries the car while it's rolling away from you? Put yourself in the mind of the CPU, who has detected that the power is going down, and now trying to clean up while the circuits go dead, trying to remember the last state, and the disappearing DC has rendered the memory erratic containing the bits in question. The worst kind of computer interruption around here is a power hit, which can go down in ways that leave circuits in indeterminate states. We have UPS on our two main PC's, just so the PC's can do an orderly shutdown. But there are all the boxes (washer, dryer, TVs, Microwaves, clock radios) that have CPUs in them and sometimes come up quite wierd depending on the timing of the hit. It's a new world. Hit the K3 power button (it sends a signal to the CPU, doesn't break the DC) and let the K3 clean up before it turns itself off in an orderly fashion. 73, Guy. ----- Original Message ----- From: "Erik N Basilier" <ebasil...@cox.net> To: <elecraft@mailman.qth.net> Sent: Sunday, March 01, 2009 12:58 AM Subject: [Elecraft] K3 power loss: Last settings forgotten >I just shut down the station by "pulling the big switch" and then turned it > back on soon after.
