Re: [Elecraft] K2 INFO 232
OK, thanks, Don. As I said, I went into this perfectly happy with how the K2 is performing. I have SN 6911 right beside it and find no discernible difference between the two. Both are solid. I just wanted to verify the alignment after 13 years of use and refamiliarize myself with the internals.

Re: [Elecraft] K2 INFO 232
Chuck and all, Sorry if I confused you. It is the firmware level, not the upgrades or the board level. Firmware 2.01 and above must do CAL PLL on 40 meters. That calibrates it for all bands. The early manuals tell you to do CAL PLL on each band, but if the firmware has been updated, the instructions for the updated firmware can supersede the earlier instructions in the manual. 73, Don W3FPR On 4/20/2018 8:27 AM, hawley, charles j jr wrote: So A to B upgrades but not necessarily the rev B board?

Re: [Elecraft] K2 INFO 232
Chuck, If you are referring to the X1/X2 situation rather then the CAL PLL band, even the rev B boards have silkscreen and holes for X2, but X2 is left open. The BFOMDKT and the Thermistor mod replace X1 and remove X2. The basic A to B mods do not, but those mod kits are a part of the overall A to B mods. 73, Don W3FPR On 4/20/2018 8:27 AM, hawley, charles j jr wrote: So A to B upgrades but not necessarily the rev B board?

Re: [Elecraft] K2 INFO 232 error with PLL
Dick, With the K60XV installed, do your have the menu for d10 set to "Y" - i needs to be that way or CAL PLL will fail as you stated.

Re: [Elecraft] K2 - "INFO 80 " problem
Giuliano, From the Elecraft website www.elecraft.com, order K2FWMCIO - see the Order page and then Spare Parts, and then select K2 on the page which opens. Be aware that you must have the updated wiring on the Control Board for the sidetone source. If you have the KPA100 or the KIO2 installed, that change has already been made. If it is not installed, refer to the KIO2 or KPA100 manual (which you can download) and you will see the changes to the Control Board in the installation section. 73, Don W3FPR On 3/27/2014 2:31 PM, Giuliano wrote: Thanks for everyone's help.

Re: [Elecraft] K2 - "INFO 80 " problem
Go to the Elecraft website and download the K2 A to B instructions. That contains a list of related mods. You may want to also download the instructions for those mods as well. Review those instructions against your physical K2 to see if they have been installed. I would also suggest changing the IF crystals on both the RF board and the KSB2 (if installed). If the crystals installed have a "-S" suffix, they are the new type, but any other suffix is the older type. The new crystals will improve your filter passband shape. The INFO 080 says there has been a failure of AUXBUS communications between the main MCU and one of the other firmware ICs in the K2 system (that includes the IOC on the RF Board). Since it happens when you change bands, it is most likely the IOC communications. The first step is to re-seat the MCU on the control board and the IOC to clean any oxidation from the socket and the pins. If you have the KPA100 option installed, it could also be the KPA100 communication - re-seat its firmware IC too. If it persists, begin removing the installed options to see when it disappears. That problem could also be caused by a bad solder connection. If it is intermittent, it may take some time and trial and error to track it down. 73, Don W3FPR On 3/27/2014 2:02 AM, Giuliano wrote: I bought a K2 SN 670 to complete my collection Elecraft.

Re: [Elecraft] K2 - "INFO 80 " problem
hello juliano, I'll put the single "080 info" Book of troubleshooting, if it can help you If you saw the message INFO 080, the I/O controller (IOC, RF-U1) or other auxBus device did not respond to messages from the main processor (MCU). Turn power OFF and back ON; if you hear some relays switching on power-up, the IOC may be OK, and the problem is likely to be with the AuxBus (081) If you do not hear any relays switching on power-up, your IOC (RF-U1) may be defective. Inspect U1 carefully to see if you have installed it backwards or if any pins are bent. Pull U1 out, check its pins, then re-install it, making sure all pins make good contact with the IC socket. Check the 4-MHz oscillator (075). Remove the bottom cover and verify that all pins of U1’s socket are soldered, as well as those of the 6V regulator (RF-U2), and U1’s 4 MHz oscillator (RF-Z5). With power ON, check all voltages associated with U1. You should see 6V at pins 1 and 20 at all times, even when the IOC is sleeping (not being accessed by the MCU).

[Elecraft] K2 - Info 232
Hello there Name here is Peder, SM0GNS. I have now started building my K2 (s/n 7234) but have run into some problems. I am in the process of doing the PLL calibration but I receive the INFO 232 when having the VFO at 7.000. I need to put the VFO at 7.1 MHz before I can start the CAL PLL without the 232-error, but the frequency does not change as it should do. According to the manual, the VCO fq should decrease through a range of 10-13 kHz. Even after about 30 minutes nothing have happend. When measuring at TP1 with my scope, I get 2.3V p-p and the fq is 11913.0 kHz at 7.0 MHz. I have checked all components around the VCO and the three relays, and all seems to be OK. Anybody have any clue on how to proceed?

Re: [Elecraft] K2 Info 080 Error while attempting computer contro
Gene, An INFO 080 message is caused by a problem on the AUXBUS signal, so pay particular attention to the DB-9 connector pin 6 in the cable. It might be a good idea to open the backshells to see if there is a wire whisker from pin 6 to any other pin, or a broken wire on pin 6. 73, Don W3FPR On 10/2/2011 9:11 AM, Eugene Balinski wrote: > All, > >Trying to get my K2/100/KAT-100 operation with N1MM. >Bought the Elecraft USB-Serial adapter.

Re: [Elecraft] K2 Info 080 Error while attempting computer contro
The K2 cables are not standard RS-232 cables. They only have pins 2,3, and 5 connected. This is documented in the manuals, you should review the manuals carefully to make sure you have constructed the cables correctly. INFO 080 according to the manual indicates a problem with the I/O controller or possibly the AUX bus. See appendix E of the K2 manual. I know I'm just telling to you to "RTFM" but the Elecraft documentation is pretty good. You can always download an up-to-date copy of any manual from the Elecraft web site. > Message: 27 > Date: Sun, 02 Oct 2011 09:11:14 -0400 > From: "Eugene Balinski" > Subject: [Elecraft] K2 Info 080 Error while attempting computer contro > To: > Message-ID: > Content-Type: text/plain; charset="windows-1252" > > All, > > Trying to get my K2/100/KAT-100 operation with N1MM. > Bought the Elecraft USB-Serial adapter.

Connected the cable to the computer (device found, etc). Connected the other end to the radio/antenna tuner serial cable, powered up the radio, and get the "INFO 080" error. Cycled the power, same issue. Also, and the antenna tuner will not power up while the computer cable is connected. The serial cable is the "Y" configuration running from the radio to the tuner and then to the db-9 where the serial- usb converter is connected. Turning off the radio, removing the cable and re-powering the tadio returns the radio to normal ops. I disconnected the antenna tuner portion of the cable and still get the same error. Reconnect everything without the serial-usb converter in the line and all works normally. This is not a stock serial cable. It is supposedly one made especially for this application i.e K2 "special cable". I guess I will start by ohming out the cable.

Aside from the obvious solutions of not being on 40 meters, and forgetting to connect the counter probe to TP1, It could be an indication that the counter probe is not working properly, or not enough RF voltage is getting to the firmware IC to reliably count the frequency. Put the probe in TP1, tune to 40 meters, and enter the menu for CAL FCTR. Does the frequency indicated equal approximately 4913 kHz plus whatever frequency is displayed on the K2 dial? If it does, then the counter probe is responding correctly. If you instead receive a varying frequency, or all zeros, the counter probe is not working properly. If you do not get a proper reading at TP1, then put the counter probe into TP2 - you should read the BFO frequency which should be somewhere between 4912 and 4916 kHz (depends on mode and filter selection). 73, Don W3FPR On 8/6/2011 8:34 PM, Jason Morgan wrote: > Hello everyone, > Well I am to the point of VFO Linearization in my assembly of the K2. > When I attempt the steps I am getting an info 232 error.

[Elecraft] K2 Info 232 error
Hello everyone, Well I am to the point of VFO Linearization in my assembly of the K2. When I attempt the steps I am getting an info 232 error. I have checked to insure that that I have the freq. probe attached to the correct point and that I am on the correct frequency. This is the first problem that I have had during the alignment phase of the receiver. What components should I be looking for? I have checked the solder joints and all seem to be ok. Any help would be appreciated. 73 DE K4SHP (proud to be a KNOW code ham) K __ 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] K2 info
I have had my K2 for about a year now and really have enjoyed it.I have a question on the KAT2, what else is needed after the installation of the tuner into the rig? Set the swr and power out? band assignments ?

I've found that the best way to discourage their wandering is to double check the place at least twice before soldering and once after before going on to the next step. That way only once have I found that the part moved before soldering... And yes it was a 7-pin resistor pack! Did get it out though...but Whew!.. That's a chore for ANY desoldering technique!

Re: [Elecraft] K2 Info 090 at first test
You're right, most of the failures I've had with projects have been from misplaced parts or poor solder, but I usually spot them before sniveling for help. In this case, I spent a couple hours looking at it for part placement errors, and looked at every solder joint under my stereo microscope (Every blind old fart should have one!). Most of the projects I work on are surface mount, but I'm reasonably sure I haven't forgotten how to solder through hole components. I've haven't built anything with serial interface EEPROMs before, it's possible I'm misunderstanding what it wants. I'm seeing bursts of legal 5 volt logic signals on pins 1, 2, 3, 5, and 6 at power up. Solid +5V on 3, 7, and 8 and ground on pin 4. I think the processor is trying to "talk" to the EEPROM's pin 5 "SDI" (serial data in, I think), but it's not answering correctly from pin 2 "SDO" (serial data out?). The processor seems to be talking to the D to A converter since it successfully generates a tone signal at power up, so I think it's alive. I think a bad solder connection would show up as an intermittent or missing signal. The signals around the EEPROM look pretty solid to my old 475 scope. It looks like the processor uses the same line to send serial data to both the EEPROM and the DAC, and has a separate chip select line for each. If the processor is healthy enough to control the DAC, It should be able to control the EEPROM. I think the EEPROM is sick. of course, I've been wrong before, this may be only more proof of my idiocy. If all else fails, I'll haul it into work and look at the timing around the EEPROM with a digital storage scope, and figure out who is talking to who when. Now that I've been away from it a few hours, maybe I'll spot something I missed. Has any one else chased a INFO 090 trouble? 73 GREG WB7RSG On Sun, 2004-12-26 at 22:58 -0500, W3FPR - Don Wilhelm wrote: > I do have to disagree.

Re: [Elecraft] K2 Info 090 at first test
I do have to disagree. I consider myself a careful builder and do not often make mistakes, but even so, for myself, the most probable cause of failure with an Elecraft kit is an unsoldered connection, so without remark about the quality of Greg's workmanship, I hold to my statement - 'check soldering'!!! I speak from experience. 73, Don W3FPR - Original Message - Well, knowing Greg and the quality of his workmanship, I'd doubt that bad soldering is the problem. Also, his rf test bench is probably on the same level of, say, Ron's. Searching the web didn't show us much info on "Info 090". Too bad it wasn't "Info 80".

Re: [Elecraft] K2 Info 090 at first test
Greg, Congratulations on your early Christmas gift!!! Sorry it is giving you problems. Before you start ripping things out or suspecting bad components, remember that the design does work (and works very well), and that components rarely fail. The most likely problem is a poor solder joint or an unsoldered joint. As I say many times ' Check the soldering, then recheck the soldering, and when you have finished that, check the soldering.' That will fix the majority of problems. The second most common problem is a misplaced component - so go back over your components with the parts listing in hand and be certain all the components you have placed are correct. Good luck with it - work (and troubleshoot) in an orderly manner and you will locate the source of the problem. Sorry, but I can't pinpoint it from the information you provided thus far. 73, Don W3FPR - Original Message - My Christmas gift (OK, I opened it early) says "Info 090" when powered up. According to the manual this is "EEPROM Test #1 failed". At power up, relays click for a short period, and the display says INFO 090. The front panel buttons make the display change to many wonderful and cryptic things that I'll figure out later, the tuning knob makes things change, so I think the display board is working On the control board the regulated +5V is in good shape. The 4 MHz clock on U6 makes 5v Peak to Peak on pin 14 and is easily adjustable above and below 4 MHz. Pins 1, 2, and 3 of U7 (EEPROM) have short bursts of 5V P-P data at power up and then rest at +5V, supply and ground pins on U7 all have expected voltages. The D to A converter, U8 seems to be working, it generates a 5V P-P tone signal on pin 4 shortly after power up. Pin 1 rises to +5 volts shortly after power up. I think the controller, U6 is working, and the EEPROM is bad. Is my analysis way off here? I'd hate to do something rash, like rip out a good part to prove I'm an idiot, or make things worse fixing things that aren't broke.
