[Elecraft] [K3] short circuit at power terminals
Yikes! My reliable K3-10 has developed a short circuit across the power input terminals. Well, to be exact, not quite a dead short. It measures 0.6 ohms across the PowerPole connectors. It most certainly does blow fuses on the input line. Any suggestions for trouble shooting? And also for a possible cause of the problem?

[Elecraft] K3 Parts transfer between rigs
I embarked on a project to move parts from one K3 to another and I got the rigs back from my tech elmer tonight. After getting the K3s home, I decided to follow the procedure to get them operating again. I had my tech elmer transfer the KAT3, KRX3, KDVR3 and KBF3 from one of the K3 to the other. I now have multiple errors and not sure what is going on. The first receiver works well and I loaded the filters fine. However, when I went to load the second receiver and run the synthesizer calibration I received multiple errors.

[Elecraft] Vedr: Resistor networks, polarized?
You can remove the resistor pack by using heated solder on all the pins on one side. (You need to be fast!) Heat up one side with the soldering iron and apply lot of solder, the solder works as a heat distributor, losen one side, and do the same on the other side, use solder wick after to remove all the solder from the PCB and the resistor pack.

Re: [Elecraft] K3 Parts transfer between rigs
Keith, You can download the assembly manual for the K3 from http://www.elecraft.com/K2_Manual_Download_Page.htm#K3 and open up the rig and check for errors. It's tedious, but not difficult.

Re: [Elecraft] K3 Parts transfer between rigs
Hi Keith, This type of transplant takes more preparation then meets the eye. For example, the Sub RX also includes the addition of a KSYN3 board and an AUX DSP board. Forgetting to install either of those two boards could create some of errors you are seeing. Then there are other things to check and/or change on the existing K3 boards. Similarly, the donor K3 might have to have some things unchanged once this handful of parts has been removed. If the Elmer didn't fire up the rigs after the swap then perhaps he was just supplying skilled labor and he was relying on you to do all of the research. 73, Mike K2MK Keith Heimbold wrote I embarked on a project to move parts from one K3 to another and I got the rigs back from my tech elmer tonight.

Was the DSP2 board and the synthesizer board for the KRX3 transferred from the other K3. From the errors you are getting, it would seem that they were not. Did your tech elmer just do the unplugging/replugging job or did he check the result out after each option was transferred? What did he say when you asked him for his observations.

Re: [Elecraft] [K3] short circuit at power terminals
Hello Lewis, I experienced this same issue once, and the problem ended up being the Transil diode D28 on the main pc board, near the 12 vdc power input connection. It is a large diode, and I believe it's purpose in life is to protect against excessive input voltage. It should begin to draw current when the voltage goes too high, and that should blow the resettable fuse F1. In my case, I was running the power supply voltage at about 15.0 vdc, and I suspect that my particular diode may have had a slightly lower threshold than normal, and was probably drawing current and dissipating power, though not enough to blow the F1 fuse -- until it failed completely by short circuiting. (This is just a guess; The replacement that I received from Elecraft has been working fine though.) If you can, try measuring the resistance in both directions across diode D28. To really prove it though, you'd need to lift at least one end of that diode and then measure it. Spec sheet on the diode: http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/DATASHEET/CD0695.pdf Best of luck with your troubleshooting. 73, Dale WA8SRA On 10/19/2012 2:50 AM, Lewis Phelps wrote: Yikes!

Re: [Elecraft] [K3] short circuit at power terminals
Thanks for the input. No, I haven't had the rig open in more than a year. It hasn't moved from its current operating position in weeks. No rattling loose screws. There is a strong possibility that the input was over-voltaged due to a short in a separate piece of equipment that was powered from the same 12VDC buss. The other item has both 12VDC and 24 VDC inputs, and it's possible that the 12V line got bumped up to 24V. That would be consistent with Dale's description of the issue. I will pull the cover off later this afternoon or tomorrow morning and check the diode, and look for any obvious places where the smoke has been let out of a component. Thanks for the good feedback, guys.

Now the questions: Have you had the covers off and now it doesn't work? Were you installing or removing options? Disconnect or remove them to isolate. What have you done recently other than operate it? Have you moved it? Were you poking around inside so a connector came loose and is now touching ground? Isolation of the problem: I had a phono jack on the back that lost conductivity with ground and blew up my amp by allowing power into the amp without pulling the transmit line active. I chased the problem by using the minor resistance differences to get close to the problem area and then found 2 of the phono jacks were soldered but no connection to ground. Wire bridge to another ground point solved my problem. Try to remove/unplug/otherwise disconnect components to remove the short. You may even find that screw you lost during construction.

Re: [Elecraft] Elecraft newbie considering K3 vs KX3
Thanks to all who responded to my thread earlier this week. With your help (especially Dwight, NS9I whose incredible shack I visited the other day), and after a few conversations with David Shoaf at Elecraft, I have decided on a K3. I finalized and placed the order today for the K3/100 unit, along with the internal antenna tuner and the IF module so that I can use an LP-PAN and external monitor. All that is left now is to arrange transfer of the funds, and the thing should get shipped to me next week...with luck. I have a few things to do on my end anyway, as I don't even have an antenna mounted yet. So it will be a couple weeks before I am on the air anyway--but I'll get there soon enough. I have waited 8-10 years to get back into HAM radio, so another couple of weeks isn't the end of the world by any means. On another note, I recently received a set of the Gordon West Extra Class course materials, and have started studying for the upgrade. I've been studying electronics for the past month or two anyway, so with any luck I'll get prepared for the Extra class upgrade by the end of the year as well. Anyway, just wanted to again say thanks for all the opinions rendered by you folks. This newsgroup (reflector) is an excellent resource, and I plan to keep hanging out and learning!

Lew, with a good digital ohm meter and 0.6 ohms of resistance you can sometimes walk down the traces looking for a 0.0 (or as low as your test leads measure) short.

[Elecraft] KPA500 input SWR in standby ...a question.
Hi All, Thanks for the messages about the power up LCD blink - it's the way it should be. Now another question: my KPA500 replaces an old AL811. I noticed, when I connected the KPA500 in line, that the K3 SWR meter was giving slightly higher than expected readings with the amp in standby. Given that nothing else in my transmission chain had changed, other than swapping over the amps, I thought this was strange. I also noted that my LP100 meter would show an SWR of 1.0:1 (on the rig side of my manual tuner) while the K3 meter would show an SWR of 1.2:1. The KPA500 SWR meter agrees with the LP100. Looking at this, I put a dummy load on the output of the KPA500 and with the amp in standby, I found that on 20m and above, the KPA500 input SWR is around 1.2:1 with a maximum of 1.3:1 on 6m, measured by an Antenna analyzer on amp's input. Also, taking the amp out of line by physically disconnecting it and using a coax barrel connector to join the input and output lines causes the K3 and LP100 meters to agree. So, is this input SWR variation in standby mode, within spec for the KPA500? I didn't see this with my AL811 in line, but then I'd carefully adjusted its tuned inputs. Please tell me I'm fly specing here and to stop obsessing :) Cheers JohnVK7JB __ 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

[Elecraft] K3 Sub receiver
Hi Folks, I've been scratching my head for a couple weeks and finally decided to ask for a bit of help. Is there a way to enter a frequency via the numerical keyboard to the Sub-receiver? So far I have been setting a frequency into VFO-A then pressing the A/B key. This is a bit cumbersome but it gets the task done. And I guess there is no way to use the Sub-receiver with the 2 K144-XV2 transverter. Thanks for any help, this is a great forum and extremely helpful.

Re: [Elecraft] KPA500 input SWR in standby ...a question.
FWIW, below are my notes - from before I sent mine in for repair. Something happened that caused an LDG AT-1000Pro to toast the protection Diode, and an Icom IC-756 Pro 2 to burn one of the contacts off of the antenna 1 / antenna 2 change over relay. I had already taken the K3 out of line for unstable output before trying the Pro II. We found one of the drivers bad on the K3. It is looking like the amp is common to all items that were affected. I am in luck in that I can replace the driver on the K3, and the relay on the Pro 2. Dwayne at LDG will treat me right on the 1000Pro, so all I am really stuck with so far is the $65.00 to ship and insure the LPA500 to Elecraft, and whatever they find wrong, plus return shipping and insurance. Here is what I wrote: MFJ Analyzer shows (worse case at 50 MHz) 1.5:1 in standby and 1.1:1 in operate with dummy load connected directly to amp output. My problem is that the amp shows high SWR and REFL HI error whenever it is keyed; no matter what the power or load or band. I am guessing whatever went wrong with the amp sent a fair size spike out to both the rig and external tuner. If you are going to die, you may as well take a few with you :) I will find out soon enough.

[Elecraft] KX3 Hi-current warning at 5.0 watts on 6 meters
Has anyone seen a KX3 high current warning on 6 meters, but only at 5.0 watts? 4.8 5.2 watts are fine - just at 5.0 watts. My setup: MCU 1.23, DSP 0.99, ATU in bypass, DL1 dummy load directly connected via a double-male BNC, in CW or USB (haven't tested other modes). The display shows a 1.4:1 SWR in bypass. With the ATU in auto, I get a 1.1:1 and no issues. This isn't related to the lower-current PA mode, as that changeover occurs above 3.0 watts in USB. The error message appears independent of which current mode the PA is in at 5.0 watts, depending on the transmission mode. No other bands exhibit this. It's not a problem, just a peculiar quirk. 73, Mike, KW1ND __ 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

[Elecraft] KPA500 input SWR in standby ...a question.
Hi David Group, I did find the spec for the input SWR in the manual - it's listed as 1.5:1, so my amp is well within spec. I'm going to forget about it. I guess I'm used to old tube amps with tuned inputs you could adjust on a per band basis. This is my first SS amp, so I'm learning. Sorry to hear about your troubles and I'm sure they'll soon be fixed. Fortunately, my amp functions just fine and my SWR observations are symptomatic of nothing other than my own obsessional nature. Does anyone know the design reasoning behind using the twisted wire pair, rather than coax, for the RF output connector on the KPA500? There must be one, but I wondered what effect that would have, if any, on the impedance of the RF path through the amp. The RF input connector is coax. 73, John VK7JB __ 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] K3 Sub receiver
The internal 2M transverter IF connects into the the Main receiver input chain downstream of the Main/RX antenna switch. So it can only be used on the Main receiver. In fact the ATT and Preamp works as normal as the whole input side is pretty much connected. I have other 2M transverters here and have at times hooked them up to the alternate antenna input (ANT2) and it is routed to the Sub RX. The advantage of this is it works with either receiver but with the XV144 external unit it does not cover the FM portion of the band and does not benefit from the Reflock feature. With both transverters connected (with separate antennas or RX only with splitter) I can monitor 2 ends of the band at once and use the internal as the primary. I went further and brought out to the back panel my ANT 2 internal connection to the SubRX and the SubRX connection and normally have a coax jumper between them. I can pull the jumper and insert any transverter (or RX splitter output) and not worry about transmitting into it at high power. :-) I actually rarely use it but it is there when I need it. I see no way to enter frequency directly in Bset or other method than A/B swapping. - Mike -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-Sub-receiver-tp7564345p7564351.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
