[Elecraft] KPA100 check result questions
Good morning, I'm still in the process of building my kpa100. After my learning process concerning soldering :-) I stumbled upon some voltages. I'm on page 43 in the manual now and got some numbers a bit off the given values (PS is 14V). D13 154V U4 -27.4V TP1 0V J3+ 0.1V Are these numbers ok? Especially the last two? Another thing. The fan at this stage is a bit out of control. Calibrating tPA helps, but the K2 seems to not remember this setting. Also strange is that while setting tPA a relay can be heard switching. But maybe this is normal at this point in the process? Kind regards and keep on building... Gerhard DH3FAW ___ Gesendet von Yahoo!

[Elecraft] K2/100 Underway
Hi all. K2/100 #4703 is well underway as a replacement for an earlier build K2 #29xx which I sold and have regretted ever since - in spite of replacing it with a MP Mk5! This time it will be the Mk5 that gets sold as soon as the K2 is up and running! Thanks for all the interesting reading on the reflector.

RE: [Elecraft] KPA100 check result questions
Gerhard, The voltage at D13 and U4 are a bit higher than they used to be - they increased when R4 was changed from 100k to 39k, all is well with those two. Your voltage at TP1 is good, but you may want to re-check J3+ (red) - while 0.1 volts may just be some artifact of your meter, the voltage should really be zero. I don't have an immediate answer on your fan situation, but it likely won't hurt anything, so finish everything and see what happens with it. Yes, CAL tPA should be remembered. 73, Don W3FPR -Original Message- I'm still in the process of building my kpa100. After my learning process concerning soldering :-) I stumbled upon some voltages.

If one keeps the K2 connected to a 14.1 to 14.3 volt power supply that is continuously running, the battery should stay charged.

[Elecraft] RF Board Relays ..Help..!
Guy's... Getting on with the K2 RF Board here .going together much better than I antisipated...although I have workmen in the house here at the moment...fitting a new bathroom suite and layout... SO..! at times its hard to concentrate with all the noise... Just wanted to enquire... I am at the stage of the RF Board where one installs the relays onto the RF Board,I have located the 2 PACKETS of relays I got with my K2... What I would like to clarify is On one of the tubes of relays there is a white label with the words KAT2 Relaysand other the other tube there is NO label... As far as I can see...from the markings the relays are exactly the same in nature all ways...(perhaps not..!)... Does it matter which ones I use for the part in the RF Board that I am currently putting together..?? As for those wishing to follow my progress, slow as it has been over the last year, with one thing and another... I will post some photographs on my website as soon as the board is done...along with my thoughts on the processAll comments would be greatly welcome...

Re: [Elecraft] KDSP2 - LED REMAINS ON
Hello Chris! I have just built the KDSP2 and everything seems to work properly, including the clock and changing the filter frfequencies. However, the red LED remains on... This is certainly peculiar. If the DSP is working, the first thing it does is turns off the LED. This feature is controlled directly by the DSPx module, not the KDSP2 kit MCU. Since the DSP appears to be working, I'd be suspicious of a short at the collector of Q4 or R13 on the KDSP2 kit portion. You might try removing the DSPx but leaving the KDSP2 installed, power on the K2, and then *carefully*, using a spare resistor of 1K to 10K ohms, pull the end of R13 nearer J1 to ground. This should cause the LED to extinguish. If it does, the problem may be in the DSPx. If not, the problem is in the KDSP2 circuitry associated with R13/Q4. Another test is to use a voltmeter and probe P1 pin 4 on the DSPx. The voltage should initially be around 3 to 3.5 volts, then drop to under 0.5 volts. When the voltage is at the lower level, the LED should be extinguished. 73, Lyle KK7P (who would have reponded sooner, but was in Germany last week) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Trivia from G0XAR
Stephen wrote: Hello and have fun. I used an old pencil soldering iron, clamped it vertically, removed the tip and filled the cavity with solder. I then dip the end of wire into the cavity. Works very well. That's how 2330 got done. take care. Hi gentlefolks, Home construction has re-commenced at G0XAR after a lengthy gap due to heavy work commitments and having to re-establish a shack, and aerials (thanks to M0PUB and G0BBL for a very pleasent summer weekend getting them rigged...). I found some transparent small (1 meal sized) freezer boxes in Lakeland Plastics on St Stephens Street in Norwich (they have branches in other towns however I am not sure about the colonies ;-) ), they were about £4 for 50. These are the same form factor as used by some Chinese takaways and are really handy for component storage - being transparent you can see whats in them - and they stack. So I have said fairwell to all those altoid tins. tobacco tins and biscuit tins...stuff is easier to find and things are much tidier as a result. Having only a little time to fool around in the shack means that every second counts...I would rather spend it making things rather that looking for things... I am currently constructing Yet Another Small Aerial a 5 foot whip tuned by switchable toroids. In the course of building a VSWR indicator for it I have found the Copper Island Construction Kit I bought at Rochdale some years to be very useful...not sure if these are available any more , The concept is to use a piece of single sided PCB as a ground plane and to superglue small discs of PCB material to it - these islands are then used to solder the components toonce one gets used to the technique it is a remarkably quick way of working. Once this is complete I'll probably start work on my K2 - Number 3354, which will be fitted with the Top band, ATU and SSB options - I understand that there are people who like to keep track of where all the K2s are - well 3354 is here in Norfolk, England. Just out of interest does anyone know where I can obtain or how I can make solder pot. Like most of us in our 50s my eyesight is not what is was. So tinning component leads, for example Toroids, can be a challenge..it seems to me that using a pot might make things easier. Lastly I have a couple of Howes kits - a frequency marker and a direct conversion RX covering 10, 15 and i think 18 Mhzthe marker works, the RX needs completing..happy to pass them on to a good home. And does anyone have a spare Norcal 38 Special kit they wish to part with.mine seems to have been lost in the move from Wiltshire to Norfolkand I would dearly like another one -- 73 Fernando N2FQ/NNNØJYM San Jose, CA http://pages.sbcglobal.net/n2fq ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Re: It Works, but Not Inst Message
Hello Christian, The issue, though, is that when I tap the menu button or the display button, not inst will flash for a second before the menu is displayed. All tests checked out after power up, except the keyer, since I don't have a paddle. Let me add that at this point, I am missing one pushbutton switch, S16, which I am waiting on a replacement for. An not installed pushbutton is as good as an not switched pushbutton. No problems with it. First of all check the right orientation of the resistor pack RP1. I had installed RP1 in the wrong direction and the results was very strange and currios. Then check the orientation of RP1 again. No, its no joke. Please do it. Then check pins 3, 4 and 5 of the resistor pack RP1 on bottom of the PCB and (!) on the top of the PCB. I think there is a solder bridge from pin 4 to 3 and 5. Pin 3 is the DISPLAY and pin 5 is the MENU and in the middle pin 4 is the ANT 1/2 which is not installed in your K2 at the time. U2 is an multiplex IC, so sometimes the bridge suggested the MCU U6 a switched on display button or sometimes a switched on menue button (to be governed by the U2 multiplexer status) or all seems to be OK. -- 72/73 de Ingo, DK3RED Don't forget: the fun is the power!

[Elecraft] KSB2 Capacitors
Hi, I have a KSB2 kit supplied about 11 months ago. The instructions are Revision D. I see there is a Revision E on the website.

[Elecraft] KPA100 voltage measurements AGAIN
Hi there, since my last thread has gone wild ;-) ... here comes a new one. I just checked the PCB again for any visual problems but didn't find any. And then I did the measurements again. I now have -0.1 to -0.15V on J3+ (yes, MINUS). Still zero V at TP1. Any idea how this voltage could get there? I don't dare to neglect this reading and proceed with the building... Using a 4.7k resistance I shorted J3+ to ground and almost immediately the voltage rises to 0V. Taking it away results in a slow drop to abt -0.1V. It looks like discharging/charging a capacitor.

[Elecraft] Help with K2 Q7 collector resistance test
Hi all, I have been through the archives so I know this has been asked and answered a few times but I still am not making much progress on this. The problem is that my resistance test for Q7 collecter is not correct. With the common probe on ground and the positive probe of my DVM measuring resistance, its abt 280 ohms. If I reverse the leads, its around 408 ohms. All other measurements seem okay. I have the heat sinks unscrewed and point in the air, not touching anything. I have remove T4 (as it looked like it could be a source of problems) and the measurements are not changing. I have magnifying glass inspected things, blown the top and bottom of rf board with compressed air, etc with no real movement. Prior to the alignment in part two, the resistance reading on the 12v line was 788. I did not realize that the polarity of the DVMs could change the reading so I have no idea if I had the common probe grounded or vice versa. The alignment and test of the part 2 instructions went as expected. Any ideas to unblock me?

[Elecraft] 2 k2
David, I've been an SO2R operator for several years with a pair of IC-765s and completely agree with other's SO2R sentiments. I sold those 765s with the idea of replacing them with the much better receiver specs in 2 K2/100s. I just built my first K2 (#4687) and gave it a good work out in the 160M contest this past weekend (475 Qs and 62 Mults). I WILL be getting another one in the next few months to complete my SO2R station. Once you get used to hearing one band in your left ear and another band in your right ear, the SO2R concept is that you can effectively increase your score by calling CQ on one band while hunting and pouncing on a second band. You can be your own multiplier or added QSO hunter. I have another idea that may be possible with 2 K2s; diversity reception and panoramic reception. Admittedly, both of these concepts caught my interest in the TenTec Orion, but you can buy 2 K2s and still have enough change left over for a weekend vacation. I really am fascinated by these Orion features and I think it might be possible to achieve with 2 K2s, however, I am not technically competent enough to go much farther than concept with this idea. My understanding is that the PLLs would need to be exactly synced or both rigs would need to run off a single PLL before either of these could be correctly implemented. Maybe someone technically oriented has a thought on this. Bob K5WA ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

RE: [Elecraft] KSB2 Capacitors
John, Those capacitor value changes will change the filter bandwidth from the older 2.1 kHz bandwidth to the newer 2.3 kHz width - nothing but the capacitors need be changed. That is the only change (and it is equivalent to the KI6WX filter bandwidth mod). Yes, I do recommend it - unless you want the slight increase in audio punch that the narrower bandwidth provides, that may be important to you if most of your SSB operation is at QRP levels. 73, Don W3FPR -Original Message- I have a KSB2 kit supplied about 11 months ago.

RE: [Elecraft] Help with K2 Q7 collector resistance test
Neal, Try removing the Control board to see if the resistance moves up substantially - if it does, look for the problem on the Control Board or its connectors, oterwise look for the problem on the RF Board. The best advice I can offer is to look at the schematic and find all the points marked '12V' and then carefully examine each component (correct component, good soldering, etc.)that is connected to that 12 volt line - there are several on the RF Board (and don't overlook the connectors). On the control Board, the 12V line connects to U3 pin 2, the 2 voltage regulators U4 and U5, and to one end of R16 (to feed the AF Amp). -Original Message- I have been through the archives so I know this has been asked and answered a few times but I still am not making much progress on this.

[Elecraft] Sounds Sweet - Alternative
I purchased the Sounds Sweet speaker and am quite satisfied with it as the external speaker for my K2. However, shortly after receiving the speaker, the October 2004 issue of QST came in the mail. This issue had a cover story on building your own high-quality speaker and it looked quite interesting. It did seem to require some minimal (?) woodworking skills but all in all it looked pretty good. This speaker is more geared to the audio frequencies used by hams, with a switchover for music, etc. The Sounds Sweet is really a general purpose speaker. Had I not already purchased the Sounds Sweet speaker, I may have tried the QST speaker. I mention this to anyone who may be turned away by the price tag on the Sounds Sweet. (It cost me almost $130.00 with s/h and NY State sales tax). I didn't price the parts of the QST speaker, but my guess it would less expensive to build. It's my understanding that Elecraft was also considering a speaker and had a few prototypes made up. It's also my understanding that they have decided not to go forward with this -- any insights on this from anyone?
