[Elecraft] Proper resistance for Q7 collector

RE: [Elecraft] SO2R setup
Just as a reminder to those of you who are contemplating SO2R operation with the K2 - the stock K2 cannot properly use PTT for steering between the transceivers when in CW mode because the PTT line is the same as the DOT input. If the SO2R enabled program steer CW by switching the keying, things will work fine, but I believe there are some that key both rigs and depend on the PTT routing to select the proper transceiver. I am investigating the methods used by various programs right now. There is a 'cure' - take a look at my 'PTT for CW' article on my website www.qsl.net for the schematic. The photos currently have my 'haywired' prototype, but I am working on a dressed up version that I should have completed in about 3 weeks. No changes to the electrical operation, but a much 'prettier' packaging arrangement. 73, Don W3FPR -Original Message- From: [EMAIL PROTECTED] I used a TopTen DX Doubler to interface the PTT and mic audio between the two rigs.

RE: [Elecraft] Proper resistance for Q7 collector
Neal, The exact reading depends on your particular DMM. The only real way to tell is to use your DMM on another K2 and compare (or find someone else using the same DMM). With my K2, I read about 600 ohms when I first apply the test leads and climbs to about 1000 ohms after a time - then reversing the probes, the reading starts out at 600 ohms again and climbs to about 3K ohms after a time. If you remove the control board, you should see a more steady reading - in my case about 1k with the probes in one direction and about 3K in the other. With the control board installed, the readings vary as above largely due to C28 charging through R16. Actually, your 900 ohm reading may be just fine, but be aware that it will be meter dependent. 73, Don W3FPR -Original Message- I am progressing through debugging the bad resistance reading between ground and the collector of Q7 on the RF board.

My thanks to a super Elecraft team - #4570 is up and running, and I couldn't be more pleased. The person who posted the suggestion to put parts on a piece paper with tape has my gratitude - I had everything except the resistors (and big parts) stuck to about 10 sheets of stiff paper, and it was so easy to find parts, in addition to which it made the inventory checkoff procedure easier. I found the toroids to be bearable, but a little bit on the tedious side for shaky hands.

Re: [Elecraft] SO2R setup
In CT, CTWin, NA contesting programs the PTT delay is used to immediately key the radio (and amp, if used), delay the keying from the program for a user defined time, send the CW from the PC buffer and quickly drop the PTT. PTT delay will not work with the K2 because it is common to the dit line, or it will key the radio to full power, depending on how the keying is set up. I'm not sure about N1MM WroteLog and TRLog, but I believe they are the same. I have a box with a couple relays and a transistor to use LPT1 pin 14 to switch the keying line, amp relay line and eventually (when I get around to it) switch RX audio. Probably by the time I'm done with my homebrew box I'll have the price of a DX Doubler and then some in it! 73HankK8DD W3FPR - Don Wilhelm wrote: Just as a reminder to those of you who are contemplating SO2R operation with the K2 - the stock K2 cannot properly use PTT for steering between the transceivers when in CW mode because the PTT line is the same as the DOT input.

[Elecraft] Remoting the KPA100 without a KI02 in the K2
I now have my newly assembled KPA100 running in a separate EC2 enclosure without a KIO2 in the K2. For me it is a temporary solution until I get a KIO2, but at least the setup described below actually works. 73 Sverre LA3ZA http://www.qsl.net/la3za/ -Original Message- From: Sverre Holm [mailto:[EMAIL PROTECTED] Sent: 8. desember 2004 12:09 I am building a KPA100 and intend to remote this into a separate EC2 enclosure along with the KAT 100 My K2 does not have a K102 control board. Can I do the remote installation using the K102 on the pa board ? The notes I downloaded seemed to suggest that the k102 needs to be in the K2 . I looked at this also, as I am in the process of building a KPA100 which I intend to remote. I don't have the KIO2 in my K2. When the KPA100 is in a separate enclosure, the RS232 interface in the KPA100 will not work as it doesn't get the data in/out from the K2's processor. Instead the KIO2 does the translation to RS232. Therefore, without the KIO2, you can get the KPA100 to work remotely, but you will not get an RS232 interface. If all you want is to get the KPA100 to work, you will have to do the following: - Install an RS232 connector in the K2/QRP lid - Connect GND to pin 5 - Connect AUXBUS to pin 6 (KIO2 has 15 uH in series and 0.001 uF to GND) - Connect VRFDET to pin 7 - Connect 12V to pin 8 - Connect 8R to pin 9 (KIO2 has 3.9k in series) These connections shall be taken from connector P4 (Aux I/O) on the K2's control board. Alternatively, if the KAT2 is installed, all but 8R can be taken from it. I haven't tried this myself, but there shouldn't be too many uncertainties in this. However, the cost/effort of getting an KIO2, is not that much greater than doing the above, so I am still debating with myself whether it is worth trying. 73 Sverre LA3ZA http://www.qsl.net/la3za/ ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KSB2 Question
Off List Reply Follows - copied to the reflector Hi Jeff. I don't have the schematics in front of me but some of the crystal filter capacitors were changed in the later revisions to widen the response from about 2.1 KC (actually measured about 1.9 at 6 dB down points on mine) to about 2.4 KC. These caps are a part of the xtal lattice filter and are identified on the schematic as CA, CB, etc. The old standard was the approximate 2.1 kc width and the new standard is the 2.4 kc width (maybe it was 2.3 - something like that). As I recall, a couple of other changes were made - a couple of resistors and an electrolytic capacitor - and additionally, enhanced xtals were available and still are as matched sets. Just my 2 cents but I'd change the xtal lattice caps to the new values now during initial construction. Removing those caps is a real pain later - this from experience as I've done it a total of 3 times to get various widths. All in all, the 2.4 width is very nice! As for the matched xtal set, I did change out mine and noticed no difference at all. Others have reported that it did make a big difference.

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. Is this message a problem or something to worry about? Like I said, everything seems to be working just fine, except for this message that flashes occaisionally. I couldn't find anything in the manual regarding this. Thanks, Chris KC9GSV ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] SO2R setup
My solution for the K2 PTT problem in CW with CT and the Top Ten DX Doubler: unplug the mic connectors! It's worked fine for 4 years so far. On the other hand I have only operated SO2R in CW contests at QRP and 100 watt levels so far (no external amps). IARU and other mixed-mode contests would require Don's solution. 73 Gary, N7IR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] SO2R setup
Thanks Ed for pointing out the ambiguity: I meant the K2 mic connectors. The TTDXD interface connectors also carry headphone audio and keying signals to the tranceivers. 73 Gary, N7IR At 04:26 PM 2/2/05 -0500, you wrote: gary: Unplug which mike connectors - in K2 or ten ten dx doubler Ed, AE4EC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] It Works, but Not Inst Message
Chris, The 'not inst' message is normal when the NB or ANT1/2 bttons are tapped - it is NOT normal for that message to appear when the MENU or DISPLAY buttons are tapped or pressed. First check the orientation of RP1 on the Front Panel board - the dot (or stripe) on the R-PAK (RP1) must be at the pin 1 end (look for the round solder pad at the pin 1 end - the rest are square pads). After that, check for any solder 'bridges' at the pins of RP1 and the pins of U2. Also be certain that RP1 is the correct value (100K - look for a '104' somewhere within the R-Pak labeling). Check especially for shorts between pins 2 and 3 of RP1 and pins 4 and 5 of RP1 - a short between either or both of these pins wouuld cause the symptoms you are reporting. Since you say that it happens mainly when MENU is tapped, the short between pins 2 and 3 are the most likely culprit - you may want to check this with an ohmmeter. If all is well, you should measure approximately 200k with one probe on RP1 pin 2 and the other probe on RP1 pin 3 - if it is significantly lower than 200k, you are on the path of the problem (short or high resistance leakage path). Bottom line - either something is shorted to something it should not be or there is some sort of 'sneak path' reulting from incorrect orientation of RP1. Refer to the schematic of the Front Panel for verification of my analysis. 73, Don W3FPR -Original Message- I would like to thank everyone for responding. Unfortunately, I still do not have this problem solved. Very frustrating! After some more poking around, here is what I can say about this. It only happens when I press 'Menu', not when pressing 'Display'. It is intermittent, although it happens more often than not. After pressing 'NB', it seems to go away for a while. I have checked all my soldering on each board. I could not find any solder bridges anywhere, nor any globs of solder not on a pad. I checked the direction of all diodes and the are all correct. H...

[Elecraft] 40 Trans alignment
Hi all. I'm in the home stretch on K2 #4884. Doing the 40m transmitter alignment. The question I have is where should the max output be when adjusting L1 and L2? If I keep turning either one to the bottom of the can the PO goes up till I get a High Current warning. Should I stop at 2 Watts or go as high as possible without getting the warning? Thanks. -- R.

[Elecraft] K2 #4684 passes final test and alignment
Hello all. #4684 has passed stage III test and alignment. I'm getting anywhere from 10.2 to 10.4 W out on all bands when the K2 power control is set for 10W. Now onto final assembly and installation of the KPA100, SSB adapter, and 160m adapter. Thanks for all the help so far. -- R.

[Elecraft] AGC setting - reality check please
Hi folks - After reviewing the reflector archives regarding AGC setting and volume I decided to set my AGC in the manner Don Wilhelm describes. I took a quiet band and adjusted R1 just down to the point where I hear no difference in the band when I turn the AGC off and on. I made sure that I went no further then I had to and checked all bands. AFTER that I looked at the voltage measured on U2 pin 5 because I did not want the suggested 3.8v to cause me not to believe my ears - so to speak. The AGC is now set perfectly per Don's instructions and the voltage reading is 3.3v. Reality check - that's a fair bit awy from 3.8 - is that acceptable or does it suggest something is wrong? Thanks you in advance. 73/Tim NZ7C ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K2 a problem solved
A couple of weeks back I sought help for a problem encountered at the first stage of 40 Meter Transmitter alignment (Page 75). The problem was uncontrollable output power. Specifically:- Holding 'Tune' after requesting 2.0W output yielded a 'Hi Current' display and an indicated power of 19.1W. Don / W3FPR came to my assistance explaining how the K2 compares requested power with detected power to develope the required signals to adjust the drive to get the output power to the requested level. With Don's guidance we explored all the circuitry associated with this process but found everything to be OK which led Don to the conclusion that the high output was resultinfg from spurious oscillation. At this juncture Gary took over and the first issue was to determine whether the oscillation was inherent in the transmitter chain itself or a fault in the t-r switching circuitry. The answer to this question was provided by removing link W1, which immediately stopped the oscillation --- almost certainly the problem lay in the t-r circuitry --- a systematic 'trouble shoot' around Control Board Q1, Q2, Q3, Q4 and RF Board Q23 established that Q4 (2N7000) was the culprit. Tiresome though it was for a while, the nice part of this exercise was that by taking it slowly and getting good advice from Don and Gary I was able to achieve a result without any unnecessary 'invasive surgery' --- I only had to 'pull' one component, the faulty one --- left to my own devices I don't think the boards would have still looked as attractive as they do. A final word --- this is the second 2N7000 that has brought me undone on this build --- earlier on Q5 deprived me of sidetone for a while, obviously these mosfets are rather fragile devices --- whilst I did not use a mat during the build I did diligently wear a wrist band whilst assembling sensitive devices although at the time I thought that with our relative humidity being quite high that this was probably 'guilding the lily' --- I shall be more circumspect in the future. With continuing appreciation of this reflector and particular thanks to Don and Gary I''ll stop chewing up bandwidth.
