[Elecraft] Button of no return
I was in the Tune mode. I accidently hit the Power button to exit. The display went blank. Now nothing works. Removing power and restart with Power button gets the blank screen. Help!

[Elecraft] Button of no return
I was on 160m in the Tune mode on my K3. I accidently hit the Power button to exit. The display went blank. Now nothing works. Removing power and restart with Power button gets the blank screen. Turning it on with the Shift/LO knob depressed brings up the meter and bandwidth legends and EE INIT but mutiple pressing of the DISP button have no effect. I tried reloading MCU but the K3 utility cannot connect to the K3 - just keeps trying different speeds. Help!

Re: [Elecraft] Button of no return.
Rule 1: NEVER use the POWER button to escape from the TUNE function. It can cause your MCU to crash and lose its mind. Rule 2: When reloading your MCU, make sure the 15pin ACC plug is disconnected or the MCU will not initialize. Rule 3: If you have your K3 all set up the way you like it, run the K3 Utility and Save your Configuration to a file so you don't have to start from scratch when you break Rule 1. Thanks to W3FPR, VK1ZZ and especially K6KR who hit on the acc plug. -- 73, Dick - K4XU with egg on face __ 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] Button of no return
If this is the case, then surely it is something that can be easily addressed in the F/W. i.e. if the TUNE function (or any other critical function) is taking place, ignore presses of the Power button. Of course, this may not help if the PowerPole connector falls out ! 73 Stewart G3RXQ On Wed, 12 Mar 2014 21:53:31 -0700, Dick Frey wrote: > I was on 160m in the Tune mode on my K3.

Re: [Elecraft] Button of no return
Yes - the dreaded Power Pole plug fall out! I have had them fall out with only the slightest of movement (factory installed). Temporary solution is to cable tie the red/black lines to the antenna cables - thus supporting them and preventing movement. The final fix will be the removal of the Power Pole system completely, later this spring.

Re: [Elecraft] Button of no return
Hi Stewart, There may be a firmware solution to prevent this problem but I don't think it advisable to ever ignore the power button. The Power Button is like an Emergency Stop button. It needs to be 100% reliable. 73, Mike K2MK Stewart@twinwood wrote > If this is the case, then surely it is something that can be easily > addressed in > the F/W. > > i.e. if the TUNE function (or any other critical function) is taking > place, > ignore presses of the Power button. > > Of course, this may not help if the PowerPole connector falls out ! > > 73 > Stewart G3RXQ -- View this message in context: http://elecraft.365791.n2.nabble.com/Button-of-no-return-tp7585411p7585419.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] Button of no return
I do not dislike Power Poles and use them for many cords around my station. The problem is that my K3 is fed from the power supply using large (stiff) diameter conductors. Brushing up against these can cause them to disconnect from the K3. If the K3 is powered up, this can result in the K3 going off to never-never land which requires a special, and not well documented, procedure to get it running again. I think the K3 needs a better connector here. 73, Roger On 3/13/2014 9:52 AM, Mike Harris wrote: Not a flame just a simple power pole observation.

For a typical six foot power cord that's takes the resistance in the wire from 0.01 Ohm (1/100 th of an Ohm) down to about 0.006 (6 milli-Ohms). The problem isn't in the resistance of the wire - the resistance in the silly PowerPoles is 10 times the resistance on the wire *if the Power Poles are assembled correctly*. High current Molex connectors are marginally better, particularly if multiple pins are connected in parallel. It's high time that transceiver manufacturers start using high voltage final transistors to reduce both the current and IMD as well as go back to nice heavy 1/4" bolts (studs) for the high current connections. PowerPole and Molex connectors may be nice if one is playing with QRP current levels but they just don't cut it at 10 to 25 amps. The high current, "hot plug" power supplies use multiple contacts to keep the resistance (and heat, losses) in connectors down. 73, ...

The problem is that my K3 is fed from the power supply using large (stiff) diameter conductors. Brushing up against these can cause them to disconnect from the K3. If the K3 is powered up, this can result in the K3 going off to never-never land which requires a special, and not well documented, procedure to get it running again. I think the K3 needs a better connector here. 73, Roger On 3/13/2014 9:52 AM, Mike Harris wrote: Not a flame just a simple power pole observation.

Re: [Elecraft] Button of no return
I think that I would be rather miffed, if in the middle of a contest or worse an expensive DXpedition the power went off (PowerPole or not) and I found the K3 software settings corrupted. Most early computers monitored the power rails and shut down gracefully. 73 Stewart G3RXQ On Thu, 13 Mar 2014 09:22:16 -0700, Phil Wheeler wrote: > Agree re firmware fix if possible.

Also, have had no problems and I install on all of the equipment I have. I had more than my fair share of Molex issues. I prefer the Power pole and do not solder...

Re: [Elecraft] Button of no return
I tend to agree Eric. I have not commented yet. We need to understand what happened with the original message in this thread and more importantly how to prevent it. Power cuts happen, for whatever reason and we can't have them bricking the radio, whatever it happens to be doing at the time. I am sure Elecraft have been working on it, probably late into the night. For the record, I like my K3, it has excellent design and is one of the best transceivers available to date. Much of this is due to firmware which has no doubt grown to be a very complex system, with all that entails. I like powerpoles, they work well and mine don't fall out. They easily handle 30A. Crimps are best avoided unless done professionally so I always solder them. They have revolutionised my station's configuration providing quick reliable foolproof 12V interconnects.

Re: [Elecraft] Button of no return
I suppose they could install a two-button push for power, as on the KX3, but that would bring other complaints, I reckon -- since some KX3 users don't like that approach -- or so I've read here. 73, Phil w7ox On 3/19/14, 11:12 AM, Ross Primrose wrote: On 3/14/2014 5:33 AM, AD6XY wrote: Power cuts happen, for whatever reason and we can't have them bricking the radio, whatever it happens to be doing at the time.

Actually, we were totally unaware of the issue of powering off the K3 during a tune causing problems.
