Re: [Elecraft] K2 S-meter adjustment
Chris, The CAL S LO and CAL S HI values are as you observed. Turn the RF Gain to full clockwise, and remove the antenna. Turn the preamp on. Adjust CAL S LO first so there are no bargraph LEDs illuminated. Then tune in an S-9 signal (preamp on or off, your choice), and adjust cal S HI for an S-9 indication in the bargraph. Usually that value will be between 23 and 19. 73, Don W3FPR On 8/27/2018 2:13 PM, Chris Kimball wrote: Thanks to Martin and Don. Yep, the age setting had mysteriously advanced while in storage.

Re: [Elecraft] K2 S-meter adjustment
Chris, On older K2s, there is no adjustment for AGC Threshold kike is found with the newer ones which have a pot to set the AGC Threshold. R1 on the control board - which is normally adjusted to produce 3.8 volts at CB U2 pin 5. You can always set the CAL S LO menu parameter and CAL S HI to produce no bars with no signal and an S-9 indication with an S9 signal. The latter is normally set with the preamp turned on, but preamp off can also be used. We are in a sunspot low, so signals may not be as strong right now, particularly on the bands above 30 meters. 73, Don W3FPR On 8/27/2018 12:38 PM, Chris Kimball wrote: Just took out the old K2 from storage and it works great, perhaps better than my memory of how to us it!

[Elecraft] K2 S-meter calibration (CW-CWRV-USB-LSB) ?
Hi K2 builders; I do have calibrate my S-meter following exactly what is tell in the building manual. I do have done this allignement CW normal mode. What I see while switching between CW reverse and USB and LSB mode is that the right led indication does not indicate most right on other modes ??? I see a little difference in S-meter indicaton bewteen CW normal and the 3 other modes ?? The S-meter indicaton is dropping one led from right. The most right led indication is done with RF control fully counter clockwise of course. Is this normal,I do have allign my filters and BFO settings all correctly. Yes I now,I am talking about details now,and what I see while playing with my new toy hi. Next days I start to build my KPA100 unit. Great building kit for sure...

Re: [Elecraft] K2 S-meter calibration (CW-CWRV-USB-LSB) ?
Jean, You can adjust the CAL S HI menu in CW reverse or LSB or USB to compensate for that discrepancy. If you have a signal generator that produces a 50 microvolt (-73 dBm) signal, use that to adjust the CAL S-HI menu parameter. 73, Don W3FPR On 7/5/2013 4:30 AM, Behiels JeanPierre wrote: Hi K2 builders; I do have calibrate my S-meter following exactly what is tell in the building manual.

[Elecraft] Elecraft k2 S-meter alignment
On page 48 of the K2 manual the S-meter alignment is done. I was able to get the Cal S low done just fine. When I then moved on to the Cal S HI ( with the RF gain fully counter clockwise) I was not able go get any segments of the S meter to light up. I adjusted the VFO full circle and not one segment of the S meter would light up. The AGC voltage was adjust to 3.80 volts DC without any problem. Also I read on the list of a similar problem and Don suggested to check RP6 pin's 9 and 10 and U6 pin 3 (all on the control board) I reheated and soldered these, actually all the pins on U6 and RP6 and this did not solve the problem.

[Elecraft] K2 S meter indications
GM OM, I have gone through the S meter Zero and Sensitivity a couple of times and am sure I'm doing it BTB, but indications of incoming signals seem low to me. Signals that I think should be a least a 7 or even a 9 are indicated as a 2 or 3?

Re: [Elecraft] K2 S meter indications
Mike, First make sure you have the RF Gain set fully clockwise, and then adjust the AGC Threshold to 3.8 volts or a little lower (never higher). The adjust CAL S-LO with no antenna connected just to the point where there are no bars illuminated in any mode. Now, if you have a source of 50 uV RF (-73dBm) like the Elecraft XG1, XG2, or XG3, tune in that signal and adjust CAL S HI to indicate S-9. If you do not have such a signal generator, you can adjust it like the book and turn the RF Gain to minimum and adjust CAL S HI to illuminate all 10 bars (or the 10th bar if you have graph in dot mode) and let it go at that. Alternately, if you have a steady on-the-air signal that you believe should register S-9, adjust CAL S HI until that signal does read S-9. The K2 (and K3) S-meter can be calibrated to the S-9 equals -73 dBm standard, but for a long time, many receiver and transceiver manufacturers designed their S-meters to get a LOT of needle swing, so if you are comparing with other transceivers that you are accustomed to, you will find the K2 s-meter stingy. As I indicated, you can perk it up by setting CAL S HI to a lower number. 73, Don W3FPR On 7/30/2011 11:55 AM, vicki glover wrote: GM OM, I have gone through the S meter Zero and Sensitivity a couple of times and am sure I'm doing it BTB, but indications of incoming signals seem low to me.

Re: [Elecraft] K2 S meter indications
Mike, I forgot to add that for best results, do those adjustments on 40 meters with the preamp OFF.

[Elecraft] K2 - S-Meter alignment/Bargraph segements
Dear OM's, thank you for reading this. Yesterday I finished the control board, the front panel board and the first stage of the RF-board - ready for the alignment, part 1. Yesterday I did all the steps from the manual, alignment part 1 sucessfully - even the S-Meter alignment and the bargraph current test. Today I switched on the K2 again and the bargraphsegment number 2 was lighting. So I decided to do the S-Meter alignemnt again. And so the mistery began. First with CAL S LO by turning the VFO-knob the bargraph segments hop from nr. 10 to nr. 7 and then to nr. 3 Similiar behavior with CAL S HI. I did the GRPH BAR - Test and only saw the first 3 segments on. Then I tried again the S-Meter alignement but no segement visible any more So back to the GRPH BAR - now not one segment is on I have to mention, that I didn't changed anything from yesterday to today an the R1 was adjusted to 3,8 Volt as shown in the manual. Has my K2 destroyed himself or what could be the reason for that bad behavior? All other things in the alignment part 1 still are ok. The RF-Gain control does not change anything. I am really thankful for every help. 73 de Guenther / OE2LCM __ 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] K2 - S-Meter alignment/Bargraph segements
Geunther, The most likely cause of bargraph LEDs not lighting is an intermittent soldering connection, and since some LEDs light while others do not, the problem is most likely found on the Front Panel board. I would suggest you re-flow the soldering of Front Panel U4, RP2, R12, and the bargraph itself. Use a hot soldering iron and add a little new solder to add a bit of new flux. Examine your soldering critically, it should flow out to an almost invisible edge line on both the solder pad and the component lead. Only enough solder to fill the thru-plated hole is required, but I like to see a small fillet of solder too. If there is just a lump of solder, you have applied excess (which can hide a bad connection), use solder wick or a de-soldering tool to remove the excess and re-solder with only a minimum of additional solder. If you are trying to use lead-free solder, be aware that it does not flow very well and requires a higher than normal soldering temperature. I would recommend that you use a 63/37 alloy lead-tin solder with a mildly reactive flux instead of trying to struggle with the lead-free solder. Even with much practice, I have not been able to make any lead-free solder flow well. There is a reason that lead-free solder is not to be used for avionics or space gear! 73, Don W3FPR On 2/13/2011 8:54 AM, Löbel wrote: Dear OM's, thank you for reading this.

[Elecraft] K2 S-meter/LED display flickers, alignment fails
Hello. I'm building K2 #6761 and have reached the first operational checkpoint. My K2 started right up and works normally except for S-meter/LED display problem I describe here. When working through the first S-meter alignment, I find that the LED display behaves erratically. First, it only operates when I'm in the menu -- the none of the LED elements light when I exit the menu. Second, when I go through the process to set the meter's low and high points, several elements -- and not adjacent elements -- light and flicker. While I seem to be able to set the low point for the S-meter, I cannot set the high point because of the way the display flickers. I can't get just a single element (9 or 10) to light. I have the meter set to 'dot' mode, but do note that the LED display seems to behave close to normal in 'bar' mode, although I still can't align it properly and it doesn't work once I exit the menu. I'll note also that my 8V regulator seems to be on the low end of specs, but I can get 3.80 Volts on pin 5 of U2. Any suggestions?

Re: [Elecraft] K2 S-meter/LED display flickers, alignment fails
Doug, The most common cause for behavior of that nature is bad solder connections. I suggest you reflow the soldering on the front panel board with an iron temperature between 700 and 750 deg F. Especially check (or reflow) the soldering at Front Panel RP2, the LED bargraph, R12 and U4. Using the menu for CAL S HI, you should be able to turn the RF Gain control so that each LED is illuminated in turn (use the BAR mode). This will allow you to see when all the bars are functional After you have the bargraph working correctly, try the S-meter calibration again. 73, Don W3FPR Douglas Furton wrote: Hello.

[Elecraft] K2 S-Meter calibration
S-meter alignment... Page 47, I've been through it but it doesn't seem to give me a useful range, I feel it should be peaking when I tune a strong signal and dropping off when there's just background noise. I have XG1, can tune it, can adjust CAL S HI to S9, but then just about everything seems to be S9. I can't help wondering if I've done something wrong. Am I supposed to be doing CAL S LO with antenna removed or anything? Is there another CAL S process I can follow, or is my QTH really surrounded by S9 noise on all bands or something? Oh, also, when you first get to P47, you have no receiver, so can't use XG1 anyway. P49 also refers to fitting the thermistor board with suitable clearance away from components that aren't even installed yet. :-) -- Nosey Nick Waterman, G7RZQ, building k2#5209. #include stddisclaimer[EMAIL PROTECTED] Design simplicity: It was developed on a shoe-string budget. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K2 S-Meter calibration
Nick, Yes, you set CAL S Lo with the antenna removed. The order of adjustment is: 1) AGC Threshold, 2) CAL S-LO, 3) CAL S HI. You may have to cycle through 2 and 3 a couple times, there is a small amount of interaction. When setting CAL S HI, first set it for full scale deflection, and then check the S-9 level with the XG1 - if the meter reads a bit below S-9, you can increase it with CAL S HI, but if it is higher than S-9, go back and change the AGC Threshold by a small amount (I suggest 0.2 volts at a time) and re-do CAL S LO and CAL S HI again. Repeat the process until you have the S-meter deflection that you want. If you use CAL S HI alone to REDUCE the reading with a 50 uV input the result will be a lack of full S-meter deflection. I know that is a bit more involved than the instructions in the manual, but such are the problems involved in 'fine-tuning' several parameters - they interact. Once you have adjusted everything with no antenna and the XG1, if you see S-9 when you connect the antenna, then you may conclude that you have an S-9 noise level! 73, Don W3FPR -Original Message- S-meter alignment...

Re: [Elecraft] K2 S meter
Howard, With regard to S meter readings it does appear at least with my K2 #4168 and a later K2 #4324 tested a few weeks back that 80, 40, 30, 20 and 17m bands come out with similar sensitivity in the level required for S9 when switched to the same mode and bandwidth. For 15, 12 and 10m there was a discrepancy with the later serial number being slightly less sensitive. The alignment appeared to be fairly well correct for both K2. With the Elecraft XG1 signal generator the testing for S9 is done at 7040kHz with the higher level output at 50 microvolts PD (50uV PD = approx -73dBm). With the AGC threshold set at 3.80V, 50uV was insufficient to make S9 with both these K2. They both needed about 63uV PD to make S9 with the preamp switched off and were slightly more sensitive when checked with CW at 700Hz bandwidth compared to SSB with the SSB filter in circuit. However during testing it was found that small variations in the AGC threshold voltage had a substantial effect on the level required to make S9. With AGC threshold at 3.80V, as noted 63uV was required for S9. Drop this by 0.1V to 3.70 V, only 40uV was required and again by another 0.1V to 3.60V, only 25uV was now needed for S9. With all of the changes in threshold voltages the CAL S HI and CAL S LO needs to be reset at each step. The effect noted was posted on the Elecraft Reflector though only raised two replies in confirmation. Again has anybody else seen this effect of rising S meter sensitivity when lowering the AGC threshold whilst testing the K2 receiver? The optimum point for the setting of the AGC threshold with my K2 #4168 came out at 3.70V, which meant the S meter sensitivity came out at 40uV PD for S9. This can be fudged to 50uV for S9 by adjusting CAL S HI if desired. Left mine as is for ease of S meter HI/LO setting as per the manual. Assuming the alignment is correct on the K2 reported with low S meter sensitivity, it may be worth checking that AGC threshold has been set to at least the 3.80V initial setting. Well worth checking the K2 Alignment Instructions on Don, W3FPR's web site to ensure that you get everything correct.

Re: [Elecraft] K2 S meter
Folks, After playing with the AGC threshold vs. S-9 = 50 uV on several K2s, I can state that the value of 3.80 volts is only a nominal value, and in my experience should only be considered as an upper limit. I have found the proper AGC threshold to range from 3.65 volts to 3.8 volts. There is some slight varaition in receiver gain from K2 to K2. This is likely due to manufacturing varaiations in the components and could also be influenced by the loss through the particular IF filter, so the really correct settings for your K2 may not match another's. First and most importantly, check with AGC on vs. AGC off to be certain that there is no AGC activation with receiver noise (no antenna conenected - and check all bands). If the background noise increases with the AGC off, the the AGC threshold is too high. That means the AGc is being activated on receiver noise alone, and does not allow hearing the full sensitivity capabilities of your K2. The highest voltage point where your reciever shows no change from AGC on to AGC off is the highest voltage YOUR AGC threshold should be set. Now, how does this relate to S-9 indications, you may ask -- well, different AGC threshold voltage settings will make the S-meter more or less lively that is for certain, and by 'playing' with the settings of AGC threshold, S-Lo, and S-hi, one can make the S-meter read almost anything within reason. If you have a calibrated 50 uV signal (such as the ouptut of the XG-1), you can set the S-meter on 40 meters for S-9 at 50 uV (I have found that this is best set with the pre-amp ON). I find it helpful to make a chart of the AGC threshold voltage, S-low setting, S-hi setting, and the resultant s-mater reading. This chart will tell you which way to move the AGC setting to achieve a higher or lower s-meter reading with any given signal input (50 uV is ideal). I have tried doing it by 'guess and by gosh', and believe me, creating the chart is the fastest way to get there - frustration will quickly set in without it - this is an exercise with 3 variables, and my brain gets confused with only 2 variables. Bottom line - the K2 S-meter can be made to be 'stingy' or 'lively' whichever is your choice. There will be some variation from band to band (a lot depends on the bandpass filters settings - do that part of the alignment first), so make your choices and set it to please you. For my clients and my own K2s, I set the S-meter to read S-9 with 50 uV input on 7040 Mhz with the K2 preamp turned on. Oh yes, for my personal viewpoint -- the S-meter reading is entirely relative because it only indicates that one particular signal is stronger than another signal. The real 'proof of the pudding' is the 'R' in the RS(T) report which indicates how well you can read the other station - and a properly aligned K2 can dig them out of the mud, and !!!that!!! is what really counts. 73, Don W3FPR - Original Message - Howard, With regard to S meter readings it does appear at least with my K2 #4168 and a later K2 #4324 tested a few weeks back that 80, 40, 30, 20 and 17m bands come out with similar sensitivity in the level required for S9 when switched to the same mode and bandwidth.

[Elecraft] K2 S meter
I set up my K2 S meter per the manual. It appeared to work normally with S9+ readings on loud signals. I then borrowed an X-gen and used it to calibrate the S-Meter readings. The calibrated settings were much lower than the per manual settings, i.e., a signal that was S-9 would read, after calibration, about S-5 or 6. I don't have a method for measuring the X-gen output. I do know that the K2 easily picks up the 1 uv low signal used for sensitivity testing. I will probably just go back to the earlier settings, but I was wondering if anyone else had a similar experience? HOWARD W.

Re: [Elecraft] K2 S meter
Howard: The standard means given in the manual for setting the S meter produces settings that are generally low, i.e., readings that ought be S9 tend to register much lower than S9. Many people have simply goosed up their settings so that signals they feel should be S9 register as such. Elecraft produces a little minkit, the XG1 Receiver Test Oscillator / S-Meter Calibrator, that creates a highly accurate .5 microvolt signal (at 7.04 MHz). Using this will give you a very accurate S meter setting for 40 meters. I cannot speak for its behavior on other bands. best wishes, dave belsley, w1euy On Nov 18, 2004, at 5:46 PM, Howard W.

Re: [Elecraft] K2 S Meter
Hello Jean-Francois, Also, be sure that the AGC is in fact turned ON. To be certain that it's on, simply tap the AGC button once. If it was previously off, that will turn it on, and if it was on already, it will simply change the AGC time-constant from either fast to slow, or the other way around. If you are concerned that you never see more thatn one of the S-Meter LED's lit at a time, then you most likely have the DOT mode selected, as opposed to the BARGRAPH mode. To change it, locate the GRPH menu item on the Primary Menu. You'll notice three possible settings for GRPH: bAr (Bargraph) OFF (No S-Meter LED's will be displayed) dOt (Only a single LED at a time will be displayed, as a power-saving feature) If you select bAr you should see all S-Meter LED segments lit when the right-most LED is lit.
