Re: [Elecraft] K3 Mystery Problem
I had this problem with #23, when I initially powered it on you couldn't power it off with the power switch. The cause turned\out to be that I had turned the sub receiver AF and RF gain controls full clockwise and through some quirk in the firmware, since there was no SUB receiver, the power off function was inhibited. The solution was to turn those controls full CCW. Wayne was the one who spent a lot of time with me solving the problem. So you might want to check that, I haven't tested to see if the problem recurs in mine if I move the controls off CCW. Ah, brings me back to my software/firmware development days. There are NO bugs, only features Doug W6JD -- Original message -- From: David Yarnes [EMAIL PROTECTED] Hi All, There are at least two of us here in Tucson with K3's. I have #96, and John, K7SVV, has #148. Recently, my K3 developed a problem where it wouldn't turn off using the power button. At first it would turn off, but cycle back on by itself after a couple of seconds. Then it just wouldn't power off. The LCD display would go blank when you pushed the power button to turn it off, but the backlighting would stay on. The radio had to be disconnected from the power supply in order to completely turn the radio off. When the power supply was re-connected, the K3 would come on immediately. A couple of days later, K7SVV began experiencing the same problem with his K3. Both of us were exchanging emails with Elecraft support, but nothing they suggested seemed to solve or clearly identify the problem. Both of us made successful firmware updates, but that didn't make any difference either. The performance of the radios was not otherwise affected. They both worked just fine. They just wouldn't turn off. Then, as suddenly as the problem appeared, it disappeared! Now, both K3's are working A-O.K. We don't know what caused this problem to start or stop, but one possibility could be static electricity. According to Elecraft support, we are the only two people who have experienced this problem, at least as far as they know. So, my question is this--has anyone else had any problem whatsoever with their K3 not powering up or down correctly? Possibly someone else out there did have the problem, or a similar problem, but perhaps it stopped before you felt the need to report it as a problem. If anyone has experienced any kind of issue like this, we would like to hear about it. It just seems incredibly strange that the only two occurances of this would be with two people only a couple of miles apart. Maybe the Bermuda Triangle has moved!

RE: [Elecraft] K3 Mystery Problem
Doug, Regarding: Ah, brings me back to my software/firmware development days. There are NO bugs, only features Expanding a bit: There are features and undocumented features. There are known bugs and undetected bugs, but there are always bugs. Most of these are a result of the well known law of unintended consequences. 73, BILL, W4RK (a hardware / firmware designer from a lot of years ago) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, December 18, 2007 11:55 AM To: David Yarnes; Elecraft Reflector Subject: Re: [Elecraft] K3 Mystery Problem I had this problem with #23, when I initially powered it on you couldn't power it off with the power switch.

Re: [Elecraft] K3 Mystery Problem
This issue was fixed many firmware revisions ago. :-) Doug - Make sure you are using the latest release. 73, Eric -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, December 18, 2007 11:55 AM To: David Yarnes; Elecraft Reflector Subject: Re: [Elecraft] K3 Mystery Problem I had this problem with #23, when I initially powered it on you couldn't power it off with the power switch.

Re: [Elecraft] K3 Mystery Problem
Yes, I've got 1.49. The new NR is terrific. I only mentioned the SUB receiver situation since in my case it WAS the problem and it only occured on the initial firmware that came with the radio. 73, Doug -- Original message -- From: Eric Swartz - WA6HHQ, Elecraft [EMAIL PROTECTED] This issue was fixed many firmware revisions ago. :-) Doug - Make sure you are using the latest release. 73, Eric -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, December 18, 2007 11:55 AM To: David Yarnes; Elecraft Reflector Subject: Re: [Elecraft] K3 Mystery Problem I had this problem with #23, when I initially powered it on you couldn't power it off with the power switch.
