[Elecraft] For Sale: K2 / 100 S/N:6959
Hi everyone- Well the time has come to sell my station. I'm living in an RV and the wife says it goes. Some I'm going to do 2M/440 until we are off the road in 5-7 years. I have a K2/100 with the SSB, I/O, the Elecraft microphone. Also included are an Astron 25A power supply with Anderson Power plugs. The antenna is a KJ7U 6-160 screwdriver antenna with the whip. I've used this radio on QRO, QRP and PSK31 to make hundreds of contacts. But alas, I can't work mobile while driving the RV. My loss - your gain. I'm asking $1750 (plus shipping) for the whole station set up. I'm at - motorcyle_jack (at) yahoo.com -- View this message in context: http://elecraft.365791.n2.nabble.com/For-Sale-K2-100-S-N-6959-tp7361918p7361918.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
Re: [Elecraft] OT Carrying radios on commercial flight
Alan - Like any electronic device, you must be prepared to turn it on and demonstrate that it works. This applies to computers, ipods, radios, etc. I travel with my 2M/440 and just turn it on and pick up a local repeater, bong it and get an answer. They usually say wow. I'm sure that if you can turn them on and receive something it will suffice.

Re: [Elecraft] OT Carrying radios on commercial flight
I never said that you would have a problem, never said I have had a problem. I've never have had one, never been wiped and swiped, just my handheld is only asked to be turned on. What I was saying is exactly what is said on: http://www.tsa.gov/press/releases/2004/press_release_0401.shtm That it will be subjected to more scrutiny which could be as simple as turning it on. Or maybe as complicated as show me the insides or the wipe and swipe. It IS UP TO the TSA official you deal with. -- View this message in context: http://elecraft.365791.n2.nabble.com/OT-Carrying-radios-on-commercial-flight-tp5329108p5329834.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
[Elecraft] K2 - KPA100 works but Tpa won't budge from 0 c. ??
I've checked out the KPA100, have it operating on the hi Amp power supply and it works great except for these two items: 1. In Fan Menu, going to LoHi setting - the fan doesn't run. If I go to the high it kicks in and runs. When I first turned on the K2 (back when I was using the normal 12v supply it ran but after awhile it quit. 2. In the TPA for the temperature will not change from 0 c. turning the encoder. Can't for the life of me figure out what might be causing this. Is it some other parameter I have to change before doing these. Anyone experience this?

[Elecraft] List Rule change, PLEASE!
Eric, Wayne and Don - I have read approximately 1500 of the post on this list. I have found some of them very informative, while others are almost useless. Why? Because there needs to be a basic rule change. I appreciate the fact that you guys get back SO quickly when someone post a problem (ME). But 99 times out of 100 all the resolution and responses are done OFF LIST. So those of us who are doing research find NO resolution to the problem posted unless the poster comes back and says what they found. Could we PLEASE post all responses on list? This gives all of us a history of what has transpired to resolve all the postings about perceived or actual problems. In fact, don't answer any response that isn't done on the list. I know, you are going to say that some posters don't read the list but respond directly to the email posting. If we make it a rule that all postings MUST be through the list or they are not responded to, everyone will get used to doing it that way. Thank you for listening and appreciate your comments.

Re: [Elecraft] K2 10W PA problem
You say the power output stays the same. Is this into a dummy load and measured with a good RF watt meter (like Bird)? If that is the case then due to power staying the same, the resistance the PA sees must be decreasing. Is this happening on all bands or just one or two? This could be related to the LPF causing it if only one or two, need to check those items in the LPF causing it. If it is all bands, I would check the items on the output side of T2 for correct value and soldering. -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-10W-PA-problem-tp5282243p5282647.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

Re: [Elecraft] K2 Tilt Bale Installation
Mount the plastic holders to the bottom first thing. Next take a loop of strong twine and tie it tight around the legs of of the bail so the loop is about tight but not quit. Take a short screwdriver and place it in between the twine loops between the legs. Start twisting the the loop by turning the screwdriver in a circle. In a short time the tightening of the twine loop will pull the legs in enough to insert them in the mounting. Be VERY careful on releasing the screw driver by untwisting so that it doesn't get away from you.

[Elecraft] 1st contact on my new K2
Well I finished 6959 a week ago and had been busy building a SWR/power meter to see actual output going into the antenna. Sitting at my bench during a null in kit building activity, I figured the time had come to test this puppy out. I was listening on 20m so I tuned a little off of the conversation I had been eaves dropping on and heard a strong signal - VY1/DL1FDH working all kinds of 8's,7's, 6's and an occasional 4 5. He said he was on Prince Edward Island in Nova Scotia. So I waited for all the others to give their call sign after a QRZ and threw mine out at about 5 watts SSB - NQ3RP November Quebec Three Romeo Papa with the nervousness of my very first QSO some twenty years ago. NQ3RP came the replay - I was in!! Tom, it turns out, was in Canada for a holiday from Germany and working some North American stations. I gave him a 59 and he likewise gave me a 59, I don't believe it but I will take it. He said I was very strong into P.E.I. with my 5 watts. As we signed off, my wife was standing behind me and she asked why I was shaking so much. I guess it was just the excitement of this first contact and knowing that this little radio I built had just made it's first of many contacts. Just thought I'd share this story and hope to see you on the air soon!

Re: [Elecraft] K2 not able to receive WWV other signal problems
Just a post to tell you about the resolution of my K2 not hearing WWV and other receiver problems. I was in e-mail contact with Don and after going through what was going on with the BFO and VFO, he suggested checking the voltages on U5 pin 7 and there was no voltage there when doing PLL. Which was strange because I did get a Band plus reading and a - Band reading on the PLL span test. So we went back to check U5 pins 1,2,3 to U6 on CB. No continuity from U6 pin 24 to U5 pin 2. I checked the soldering then pulled U6. Pin 24 was bent over and not making contact. I then used Spectrogram to set C22 on WWV, did the PLL linearization in about 4.5 minutes, and set the filters with Spectrogram also. I think this K2 is the hottest of the 3 I've built. So I just want to thank Don for sticking in there, giving insight into how the circuitry works and suggesting the simple things I over looked (like checking signal continuity!). Now on to the SSB and noise blanker.

[Elecraft] K2 not able to receive WWV other signal problems
Well after finishing the set up of my K2 I thought I'd give it a work out. I put it on 40 meters and started listening to some code-great. Or so I thought until I switched filters - nothing on FL2-4. Then I got to checking more. Seems like the CW was present on some parts of the band and not on other parts. Also a CW signal is over a 5Khz area and NEVER changes tone - just there and then later just gone. That just doesn't sound right. So maybe I should check calibrations again. Hmm.. Back to the 4 mhz oscillator and let's try WWV at 10 Mz. This is when I noticed something else really strange. No WWV signal or it is very low even with audio and rf gain all the way up but couldn't be sure . I just notice some bumm-bumm-bumm, like nothing at all, not the normal tones. Set C22 back to the default location get out a signal generator and set it at 10 Mhz - nothing heard. Set it to 10.06 and tune the K2 - hey I can zero beat it there. The minute I try to go below 10.05 on the K2 to zero beat a generator signal set somewhere below 10.05 - it's like the K2 is on some other band or part of the 30M band. If I come up from the bottom it does the same thing at 9995.0 is ok to zero beat but anything between 9995 and 10.05 is out in la-la land. Appears it's happening on all the bands at various places. I'm at a loss as to what is going on and what might be wrong. I've checked the receive circuits and tuned them and they seem to work. Parts of each band work on CW and SSB (no ssb module at this time but can hear conversions). But parts of each band seem to do this act of going to some other place and it usually happens around a 5Khz display (like 7105-7115, 9995-1005, etc.) Any ideas on what is screwed up or where to look?? -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-not-able-to-receive-WWV-other-signal-problems-tp5164865p5164865.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
[Elecraft] K2 S/N 6959 is alive!
That's the good news, now for the rest of the story. I received the K2 about 2 1/2 weeks ago. I started putting it together (without inventorying - hey the other two had all the parts so why not this one). Went all the way to Part 1 alignment. Ut -ow, I had two right side panels. No problem, emailed parts and they sent the side along via Priority Mail. So let's keep going. Ow no, I put an MV209 in backwards, removing it I broke a lead off. Ok, parts will send one along. Two weeks later, I'm still waiting. Good thing I found one at a friends house in his diode parts. So let's continue the building. Need to put the four 1-30pf caps in. Lets see, they should be here in the pan with the 50's right. No, none there, not even one. Ok, lets call parts. Oh, we're out of the 1-30's so we'll send some 1-40's along. OK, WHY WEREN'T THOSE INCLUDED IN MY KIT? Well guess what, they sent them along first class mail, 5 days with nothing to do but wait so I could finish this radio. Well they got here today. Now it's finished and on the air. Now I have to build the SSB, noise blanker 100A mods. Now, don't get me wrong, I'm not knocking Elecraft. But sometimes you only hear the good stories. This one is not so good, I'm afraid. -- View this message in context: http://elecraft.365791.n2.nabble.com/K2-S-N-6959-is-alive-tp5160629p5160629.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
Re: [Elecraft] Would you be interested in a K2 PSK31 digital interface card?
Guy - The boards as designed by EA3BLQ did not provide a line out audio signal, so using one of his boards would not provide the type audio you are seeking. While Tom's (N0SS) board does provide a fixed audio, it also requires that you make solder connections to the Control Board of your K2. If you are comfortable with doing that, then I suggest you ask Tom for his files and have a couple of boards made. Please contact Tom @ N0SS (at) arrl.net for any more discussion about your needs. I'm trying to keep this discussion only about those that are interested in the K2DI PCI boards, thank you. -- View this message in context: http://elecraft.365791.n2.nabble.com/Would-you-be-interested-in-a-K2-PSK31-digital-interface-card-tp5147084p5150046.html Sent from the [K2] 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
[Elecraft] Would you be interested in a K2 PSK31 digital interface card?
I've tried to find one of EA3BLQ's interface cards for the K2 but have not been successful. So I thought I would design a replacement since I've done PCB designs before. The problem is that if I do it, to keep the cost down, I would have to make a couple of dozen boards. So I wondered if there was any interest out there in obtaining one of his boards. My main interest is in making the K2DI VIII board on this page http://www.qsl.net/ea3blq/k2di_pci_tec_ang.htm . If you would like one please post a reply here. If I get enough responses I'll see about doing the run. If you want the K2DI PCI card also please state that also. If I get two dozen the cost should be about $20 per board ($40 for the two). If you would like a complete kit state that also. I could do the kit for around $49.50 for both boards and the electronic parts. -- View this message in context: http://elecraft.365791.n2.nabble.com/Would-you-be-interested-in-a-K2-PSK31-digital-interface-card-tp5147084p5147084.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
Re: [Elecraft] frequency variation in K2
Jeff - I had a similar problem on one of my older K2s. It would jump frequency when I started to transmit.

Re: [Elecraft] K2 Build - #6950
Steve - Great work. I have 6959 that I got a day or two later than you. I have finished the Part 1 test with no problem. This is my 3rd K2 (406 3638 done before). All I can add to what has been suggested is this Check every component before you soldered it in. Sometimes I even turn the board around (front to rear) just to get a better perspective and ensure that I'm doing it correct. But since you have it finished you can't do that now. Also I ALWAYS inspect the board after finished with a magnifier to make sure all pads are soldered and not shorted or left open. I would suggest that you pull the front panel and reheat every connection. On the switches you can heat them on the front side and add some solder (the pins don't always go through the board). That way they will make contact through the plated through hole. Good luck finding the problem.
