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. The initial frequency for CAL PLL is in the 12,960 to 12.990 range. Your TP1 reading also says that the frequency the K2 is trying to tune to is near 6350 kHz - again the problem is the d19 menu parameter. 73, Don W3FPR On 6/29/2015 11:46 AM, Dick Lamb wrote: On a K2, the freq display is way, way off; e.g., on 40 meters it's really receiving about 0.5 mHz lower.

[Elecraft] K2 INFO 232 error with PLL
On a K2, the freq display is way, way off; e.g., on 40 meters it's really receiving about 0.5 mHz lower. I tried to run CAL PLL but get INFO 232.

I do have my own working K2 for comparison purposes.

[Elecraft] K2 - Info 232
I found out what caused the 232-problem. The RIT had moved to one end (+1) instead of being at 0-position. Now the CAL PLL works. 73 de SM0GNS __ 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 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 232 error
Jason, During CAL PLL, Error 232 means that the firmware is not properly reading the frequency. 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
