Re: [Elecraft] k2 pll and ref osc issues n0xdb
Don, I found it VERY rude and out of place that you chose to OUT someone for being anonymous in their posts to this group. It is NOT your place to choose who should put their call at the end of their posts. If someone chooses not to sign their emails that is their right. I don't recall Eric or others that run this group indicating that it is a necessity. Some people find that it is more comfortable for them to leave comments, or suggestions without others knowing who they are. Either for security, safety or ANY reason for that matter. For you to not only give out someone's call sign, but to actually go as far as print out their entire name for everyone on this group to read, when they have intentionally left it off their post is completely without tact. I'm sorry I'm coming down on you so hard. I know that you do good work for this group in answering questions, you've even answered a few for me... But I just don't feel that what you did in this post was of good taste. The anonymous should REMAIN anonymous unless they choose to give their call letters or otherwise. Just my rant.

Re: [Elecraft] k2 pll and ref osc issues n0xdb
Joseph, Since you have a good frequency reading at TP3, the PLL Reference Oscillator is working, and the problem is in the area of Q18. So we move the problem area on the schematic to the upper right corner of the RF Board schematic sheet 1. Note that the VFO output goes through U3 before it gets to TP1, so try reading the VFO frequency at U3 pin 3. If you have a good reading there (reading should be 4915 kHz higher than the frequency displayed on the K2 dial for all bands below 15 meters). Since it worked once, the most likely problem is soldering, so re-flow the connections with a hot (750 deg F) iron. There is a possibility that Q17 was damaged by static during construction and failed later. As a test, short Q17 drain to its source and see if the VFO starts oscillating (you can accomplish the same thing by temporarily shorting lead #3 of T5 to ground). Count the turns on T5 carefully and look critically at the soldering of the T5 leads. If there is a visible ring around the lead, it was not well tinned - it has been said that solder connections should look like mountains, but *not* volcanoes, and that is an apt description of the condition I am referring to. The same thing applies to all solder connections, not just toroid leads. The solder should flow out on both the solder pad and the component lead to an almost invisible edge. If the solder looks more like a ball than a nice smooth fillet, it is likely that the connection did not receive enough heat. If there is too much solder, use solder wick to remove some of it. With thru-plated holes on the boards, the amount of solder required is only enough to fill the hole, although I like to see a very small fillet too. Neither the board or the component will be damaged with normal soldering temperatures maintained for up to 5 or 10 seconds, although you should use an iron temperature that produces a good solder connection in 2 to 3 seconds. If it takes longer than that, the iron is too cold, and if the solder flows in less than 2 seconds, the iron is too hot. Watch for the solder to *flow*, not merely to melt. 73, Don W3FPR Foxjazz wrote: Hello Don, Don, the call was in the subject line. Sorry for the confusion. I had the pll circuit working great with all alignments before starting on phase 3 and putting the ssb board in. As far as checking parts, the parts were correct when I checked them the second time, and the pll circuit was working. tp3 reads within tolerance. Unfortunately I broke the agc gain transistor handling the control board, so have to replace. But that shouldn't affect my issue. I was doing some voltage readings and found an issue on u5 on the rf board. pin 1 was 5 volts. U6: pin 5 was 4v on and 8 was 8 volts. tp3 reads good, and checked good. However sometimes it feels as if it doesn't check good because the band - doesn't keep the freq down on occasions.

Re: [Elecraft] k2 pll and ref osc issues n0xdb
This is Elecraft's forum and they have the ultimate switch on these things. Having said that, just to straighten up an injustice here Name and call sign is not personal information, it is a matter of public record There is no expectation of anonymity on this reflector. This IS a HAM reflector, and name/callsign in the usual places is appreciated, and usually done without any thought. Those who don't add name and callsign simply stand out by the omission. It does not take much research in the archives to see that a lot of anonymous posts are trolls, which is why it grinds on so many. There ARE what amount to technical arguments here, but the players all have names and callsigns, and after a while perhaps there are familiar takes on a given individual. People are who they are. Nothing to hide. Someone called Don (W3FPR) rude. Shows what they know. There is not a rude bone in Don's body, and even if there were, he probably has the all-time record for nearly perfect technical assistance and no one on the reflector (including the Elecraft principals added together) has his online time helping reflectorees. Beyond that he has an almost insane patience with individuals in situations that to me scream RTFM. If you somehow HAVE managed to get Don riled, you ARE over the line. He should not have to defend himself. My name is Guy, my call sign is K2AV, and if you don't like what I've said you can tell ME about it without wondering who I really am. 73 all On Sun, Apr 18, 2010 at 9:51 AM, lstavenhagen lstavenha...@hotmail.com wrote: It doesn't matter - it's 100% improper to post personal information for someone else, even if that information is obtainable elsewhere.

Hi, That would be a real shame, Don, if you were to leave the reflector. Your postings have always been extremely helpful. Personally I am highly suspicious of anonymous postings on ham forums.

Re: [Elecraft] k2 pll and ref osc issues n0xdb
I'll stop pouring gas on this after this post, but to reiterate a few things: Name and call sign is not personal information, it is a matter of public record It's the principle involved, not the happenstance that Don simply printed something about this person that's a matter of public record. The problem is posting personal information about another lister _without his or her explicit consent_ regardless of where that information was obtained. If that's ok sometimes and not others, where do you draw the line and when? Who draws it? Should be easy to see that this can get ugly fast - That's why violating privacy in this manner on a public forum is (or should be) a no-no as a matter of principle. The fact that this has to be explained is something I find a bit worrying. It does not take much research in the archives to see that a lot of anonymous posts are trolls, which is why it grinds on so many. I see no evidence here that the original poster is a troll. This would have to be demonstrated first before I would support censuring him as such. Instead, he merely wasn't posting his name probably for his own reasons. If he were otherwise engaging in troll-like behavior that would have been another matter, but I see no evidence of that so far. It's certainly not grounds for violating his personal privacy. He should not have to defend himself. The way I see it, no one should be above the rules. You break em, you get popped on the wrist, end of story. I see no reason for anyone to get special treatment. But that's just the way I see it, how I was raised, etc. YMMV.

Re: [Elecraft] k2 pll and ref osc issues n0xdb
Foxjazz, Do you have a real name and a call? We here on the Elecraft reflector certainly would like to know if you do. Q6 on what board has the bad resistance reading? The Q6 on the RF board has nothing to do with your PLL problem. Is it at TP3 that you are getting a reading of 0.00 kHz? If not, let's start from there. The most likely source of no reading at TP3 is a problem with RF Board Q19. And the problem wiht Q19 is most likely soldering somewhere in that circuit. Turn to the schematic for the RF board sheet 1 and look in the upper left quadrant (up to but not including U4) to identify all the components associated with the PLL Reference Oscillator. Check the resistance from the source of Q19 to ground - it should be close to 270 ohms - if it is higher, check the lead tinning of RFC14. You may have a solder bridge on the thermistor board (notice on the schematic that it is one of the components associated with the PLL Ref Osc). Make a quick check - the voltage on pin 5 of RF Board U6 should be very close to 1/2 the voltage on the 8 volt rail (check that at U6 pin 8). Have you checked to be certain the counter probe is still working properly? To check that, put the probe into TP2 to read the BFO frequency. If that also reads .00, you have a problem either with the probe or Control Board Q9 and/or Q10. Please be specific so we can help you better without creating a 'wild goose chase'. 73, Don W3FPR Foxjazz wrote: Hello Elecraft, Hello Don, I had the pll working before I did phase 3 and put the ssb board in.

Re: [Elecraft] k2 pll and ref osc issues n0xdb
Foxjazz, (Eric may chastise me for this post because he, not I, is the list policeman, but I will do it anyway). OK, I have learned from another ham here on the reflector that you do have a call and I looked up your name on QRZ.com. N0XDB - Joseph T. Dickerson III. Would you please use it on your subsequent emails to the reflector? It will make you seem more like a human and a ham as opposed to some troll or someone who wants to remain anonymous. In addition, I notice that you start your emails with Hello Elecraft,. We here on the Elecraft reflector are *not* Elecraft. We are a group of Elecraft owners, or prospective Elecraft owners. Many of us are willing to help you as best we can, but we are certainly not the official Elecraft support organization. If you wish to reach Elecraft support, the proper email is supp...@elecraft.com, and if you wish to reach sales, it is sa...@elecraft.com. It is a fact that some (but not the majority) of the Elecraft employees (and Eric and Wayne as owners) often monitor this reflector, but there is no guarantee of that. If your intent is to reach the real Elecraft, you should send email direct rather than to this reflector. Yes, I *do* repair work for Elecraft, and to that extent, I am an Elecraft employee, but I am paid only for the actual repair work I do. Any support I provide here on this reflector is not a task for which I have been Elecraft authorized or for which I receive compensation, and my comments are not official. I volunteer my time and comments here only as one ham helping out another ham - there is nothing Elecraft Official in my postings here on the reflector, they reflect only my own views and experiences. I have had extensive experience with many of the Elecraft products, and am willing to share whatever knowledge I have with other hams in an effort to help them with whatever problem they are having. If I do not feel I can help, I normally will not post a reply. 73, Don W3FPR Foxjazz wrote: Hello Elecraft, Hello Don, I had the pll working before I did phase 3 and put the ssb board in. It was working great, now it isn't. I thought I would run a quick voltage test before continuing. Now the pll freq is 0.000 I reviewed the test results and re-tinned T5 just to ensure good conductivity. When I ran the resistance checks the base resistence of Q6 was at 372 ohms not 100-140 as the book says. the unit turns on draws 0.24 amps 0.22 without the ssb board in.
