Re: [Elecraft] (OT) Threat to 30 meters

I've posted information about it at www.zerobeat.net If you operate CW at low poer levels, you really should read the material. As part of the ARRL's continuing look at possible recommendations for changes to the FCC rules governing amateur radio, there is a proposal to have small segments of the various HF bands where wider-band (3 kHz) bandwidth data modes could be used (WinLink is only one of the data modes which could make use of this). While nothing has been formally proposed yet and the details being discussed have changed a bit over the past year or so, the current thinking of the ARRL board is that the 3 kHz bandwidth would be permitted not over the whole 30 meter band but only between 10.135-10.150 kHz (see http://www.arrl.org/announce/ec_minutes_475.html) where I doubt there is much, if any, CW activity (data modes are currently permitted on the whole band, but tend to exist at the upper end--the proposed changes would LIMIT wider bandwidth to this region). Unfortunately there is much innacurate information being circulated about these proposals. I see it as a positive thing, not a threat and certainly not the end of the world. Most countries have much less regulation of modes and bandwidth than does the U.S. and IMHO a loosening of our rules should be viewed as a positive thing. 73, Bob, N7XY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] k2 sn 3460 VCO alignment
From the ongoing drama that is Alignment and Test, Part 2: Pages 57, 58. My hopes for a unit totally free of desoldering were dashed when I found that I had put a 27 cap in C72. On a happy note, replacing it with the proper 271 cap brought the TP1 freq down from 12 MHz down to just above 8 MHz, a satisfactory value. On an unhappy note, and the reason for this query, R30 is stuck at 8.33V. No amount of tuning L30 changes it. The VFO is set at 4 MHz..

[Elecraft] Oh No... My KX1 is to young to smoke...
Hi to all Elecraft reflector readers .. I have been monitoring this particular reflector for about 3 years now and this will be my first posting to it Elecraft Gary (AB7MY) recommended I tell my story so those of you that own KX1s (particularly) or other Elecraft rigs can learn by my recent experience .. I will now present the e-mail dialog I had with Gary which will tell my story . FYI these e-mails took place in a 24 hour period (30 March 05) which shows The QUICK Response Dedication Elecraft prides itself on .. So, here we go: = Hi Elecraft Sad day in Edmonds, WA My KX1 # 841 started smoking and its not even a teenager yet I purchased and built the kit in August 2004 and the rig has worked flawlessly since then This morning I heard FT5XO booming into the Seattle area on 40 meters and wanted to work him QRP with the KX1 .. I turned the little rig on just like always but this time there was no LED display and then I saw smoke coming out the LAMP opening followed by a harsh smell .. I immediately power the unit off and opened the bottom cover and discovered a severe circuit trace melt down . I looks like something failed causing the V+ (12VDC from an external gel cell battery) circuit trace around RP5 and under R16 and R17 to burn open (disintegrate) I don't have a PWB trace layout drawing for the KX1 board so it hard for me to tell how much board damage incurred.. I was wondering if this was a warranty issue since the rig isnt a year old yet . Thanks Denny W7SNH == Response from Elecraft Gary Hi Denny, Such damage can occur if the thermal pad on the PA transistor is worn, torn, not in place well, or if there are metal bits or burrs under the thermal pad or around the PA transistor mounting hole. It can also occur if the PA transistor mounting screw is too tight. Later KX1 kits have a nylon flat head screw to prevent over tightening of the PA mounting screw, and to prevent a short if the counter sink hole is worn or is cut too deep so the tapered part of a flat head metal screw could make contact with the inside of the PA transistor tab's hole. You can obtain a nylon screw from the local Ace Hardware, or by emailing [EMAIL PROTECTED] The damage is usually limited to the burning of the large PCB trace that runs from the power switch over to the two PCB crossovers (or visa) near the middle of the board. The trace can be repaired by cleaning off the burned residue with Q-Tips moistened with acetone or isopropyl alcohol, and by scraping and cleaning the area gently back to a sound portion of the copper trace. R16 and R17 may need to be removed temporarily so you can splice a short piece of #22 to #20 awg bare or insulated solid wire to complete the circuit if the trace is burned in two. Or, route an insulated #22 to #20 awg wire over R16, R17. Solder the wire to a good part of the copper trace which has been scraped and cleaned to bright copper. Tin the copper and then place the wire on the tinned portion and hold it down with a small screwdriver as you solder it in place. A little bit of instant glue and nail polish can be used to hold the repair in place and protect the copper from oxidation. Inspect PA choke L3 for burned wires, and rewind it if necessary. No other damage is usually found. The radio is then good as new, other than the damage to your pride and joy ;-) This damage is not covered under warranty, since if you are not using the internal batteries - the power cable should be fused with not larger than a 1 or 2 amp fuse. This is especially important if you are using an external gel cell battery or a large DC power supply of 5-35 amps (like the big power supply for your 100w transceiver). 73, Gary AB7MY = My response Hi Gary. Thanks for the quick response and comments on my meltdown condition. I did some checks since it was really bugging me why this condition happened since I have had been using my KX1 almost daily since August 2004. I removed the circuit card assembly from its enclosure and performed a visual/ohm check on L3 and it was ok I then went to PA Q6 and did a quick resistance measurement from collector to ground and it was a dead short not the 500 ohms as called out in the manual I removed Q6 and the short was still there. The only other answer I could come up with is Zener diode D7 (1N4756A) failed to a short condition Sure enough, dead short in both directions Removed D7 and with Q6 still removed I did a nice splice (if I don't say so myself) bridging the disintegrated circuit trace then powered the KX1 up using my bench current limiting power supply... All receiving functions came to life just like normal. Now, what made D7 (47v Zener) fail. I sat down in my easy chair and recreated (in my mind) all the events up to meltdown. I was trying to work

[Elecraft] Correction to Previously Stated KNB2 Un-Module Header Resistor Value
Hi Sverre, Regarding the resistor between pins J12-5 and J12-6 on the KNB2 Un-Module header, the correct value to use here is 560 ohms rather than 470 ohms as described elsewhere. This is due to this resistor being in parallel with the replacement 2.7 k ohm RF88 supplied with the KNB2. In parallel with the 2.7 k ohm RF88, 560 ohms results in 464 ohms between pins 5 and 6, whereas 470 ohms results in only 400 ohms. I don't know if this correction will have any impact on receive operation. 73, Gary, KI4GGX K2 #4067 -- I am using the free version of SPAMfighter for private users.

RE: [Elecraft] next up: advice about what girl to marry!
I would like to add my 2 cents on the subject. Having the opportunity to being on the other end of the pileup periodically, it sometimes drives me crazy trying to pull out a call because the CW is almost undecipherable. It sure seems like the sender is using a straight key and hasn't mastered the correct duration and rhythm of dits and dahs. It would probably be easier if someone were having trouble with a straight key to switch to iambic keying. At least the spacing and length of the dits and dahs would be correct. I have been using an iambic keyer so long I would hate the thought of going back to a straight key. I have seen some folks who can send great CW with a straight key. But I would bet they are in the minority.

Lloyd, I'm mostly a CW guy myself, and can understand why someone might not want the mic jack. But this is only the second request for a mic-jack hole cover I've heard in the five years the K2 has been around, so I don't think we'll be stocking them. I would suggest as an alternative to [symbolic protest? phon-o-phobia?] that you install the mic jack, but just not use it for anything.

[Elecraft] T1 Mod
I got one of the first T1's that went out the door at Elecraft, but that meant I also had to do the mod that was deemed necessary so early on. As it turned out, the hardest part was getting the glued together toroids unstuck from my fingers! I know, smooth move dummy! It only took a minute or two though--thankfully! I have found the Radio Shack solder sucker tool to be a handy device--probably not considered the best unsoldering method by master builders, but it seems to work well for me. You squeeze the air out of the bulb, apply the heated tip to the joint, let go of the bulb as soon as solder starts to flow, and whoosh! It generally opens the connection nicely. Just remember to blow out the solder that has been collected in the air line before trying the next task. Anyway, I made the changes, put the thing back together, and pushed the button--still lights up like an outhouse in a fog! Hooked it up to my Argo V (which has no tuner like my K2 does), tapped the buttons again, and the pleasant sound of relays chattering came forth. It's working FB. I haven't put the T1 to any real torture tests, like pieces of wet string or anything, but so far it seems to work great on just about every antenna I have around here. I've tried it on portable antennas, like the PAC-12, without paying too much attention to dimension precision, and it zeros right in on 1 to 1. Works great with my NorCal 40 and Sierra too. I think this is going to be an extremely handy piece of gear. Anybody with an Argo, an 817, or any of the single band kit transceivers we've been building over the last several years, should invest in one of these. It makes things so simple! I wouldn't opt for it in lieu of, say the internal tuner in the KX1 (that rig is fabulous!), but it's perfect for any tunerless QRP rig. So, I'm ready for the next mod!

Steve, I started with a straight key. In 1957, I think MOST hams used straight keys. Most emerging novices couldn't afford more than a surplus J-38 and there were only a few bugs available. Electronic keyers didn't clean up CW. The percentage of bad fists on the air then with straight keys was about the same as it is today with electronic keyers. They just offer different opportunities to mangle the code. I agree with Don that a straight key trains you to learn and appreciate proper spacing if you have someone who can give you feedback. But I don't necessarily agree that you should start there. Try them all. Find out what suits you. They are all fun. But get someone to help you with the timing. My main advice to anyone is to SLOW DOWN. Most of the bad fists with keyers are because the dots are cranked up to 35 wpm and they are still struggling to copy 15. There is a nameless ham on one of the several cw nets I am on who has NEVER sent my call properly. His only consistency is a self standing dah followed by a string of 7 dits for the 6 in my call. The rest of it is so mangled I only know its for me is that I was the last one to send something. As for iambic vs non-iambic, I never saw the point of iambic. Any efficiency from saving 2 microcalories in a 24 hour period somehow escapes me. But let's not start that one again. So I only have three pieces of advice. Use whatever key appeals to you. Don't send faster than you can receive. The second marriage is the best one, so get the first one out of the way.

RE: [Elecraft] Re: 'Threat' to 30m
Yes, I agree. I think the proposed proposal (?) with its implicit QRO, high bandwidth unattended transmissions is clearly against the QRP, narrow bandwidth (cw, psk31, etc.) trend on the crowded HF frequencies. Unattended pactor stations on 20 are like big yellow Hummers in a crowded parking lot. They need more restriction, not less.

There is nothing new in this, it is clearly outlined in the April QST. It certainly has no bearing whatsoever on CW usage of 30m, in Europe at least, where practically all CW is below 10125 or so.

The smooth, side-to-side rolling action of the operator's hand was much easier on the operator over time. Indeed, many companies welded the weights in place on their bugs so the top speed was about 15 wpm. They knew that slower and steadier got more words per minute across over time. Over the years some ops were lucky enough to work at stations where they passed traffic only with certain other ops in a closed, point-to-point setup and they were able to develop some pretty amazing speeds, but they were the very small minority of all the commercial, military or government brass pounders. ACCURACY One of the best tests I've ever used to see for myself whether I'm happy with my CW is to record some stuff I sent and then play it back several days later. Another way to test one's own sending is to use a program like CWGET that works on your computer to copy your fist. CWGET *demands* near-perfect spacing. If you can pound brass while it pumps out perfect copy, you've nothing to apologize for to anyone, even if you're using two bare wires for a 'key'. CWGET is shareware but you can download and use it for free from: http://tinyurl.com/6q2zr Along with accuracy in sending is flexibility in receiving. People have accents at the key every bit as much as they do in speech, especially with a manual key. Some of it is syntax - use of abbreviations and sentence structure - but much of it is in subtle (and not so subtle) variations in timing. So while good operators strive for accuracy in sending, they also strive to develop flexibility in receiving. After all, if everyone sent perfect, keyboard CW, we could all use a program like CWGet and forget the code entirely. But we have other modes for that, and that's why I like CW.

[Elecraft] Regulation by bandwidth
Things Elecraft tend to overlap Things QRP, so this may be an OK subject for this reflector, at least for a bit, since the proposal at the ARRL could have an impact (maybe large) on low power operations. Then again, Eric's view on this may differ. I believe the current thread on threat to 30m is part of a much larger issue in a proposal currently being discussed by the ARRL Staff and BOD. The proposal is the result of an ad hoc working group and would modify the way the sub-allocations within our bands are determined. Currently, the big distinction is between voice and non-voice (emission type). Data modes generally have been treated as non-voice and confined to the so-called CW segments (CW is really legal everywhere). We've all sorted it out, and all of us know that tuning up from the bottom of the band, you get CW (often QRQ and DX), CW (QRP, CHN, QRS, and W1AW), then RTTY, PSK, and more exotic modes. SSTV at 14.230 is a partial anomaly, since only part of a QSO involves voice. The proposal would regulate sub-allocations by bandwidth of the signal rather than emission mode, thus solving what some believe to be a problem with nascent digital voice modes ... is it voice (and limited to the SSB sub-bands) or data (and placed in with PSK31, RTTY, AMTOR, PACTOR, and the like)? The result would be that data modes occupying 3 KHz bandwidth would co-exist with analog voice (I think). Some of these data modes operate unattended which poses its own set of issues. It is a little hard to pin down, but it appears that the ad hoc working group was dominated by data-mode users, and that not all of the discussions were handled all that cordially. The proposal itself is a fairly complex and hard read ... I still have not figured out the ramifications of some of the items. I wrote my ARRL Director (W6RGG) and cautioned a be careful what you ask the FCC for approach. There may well be merit in the proposal or some variant of it, and possibly the current allocation algorithm has not kept up with the new technologies and communications modes. On the other hand, I also wonder what percentage of hams actually fool around with these modes, and whether or not this is a small group's solution to a problem the majority of us don't have. It reminds me a bit of the hubris surrounding Social Security now, most of which would disappear if we all followed the proven engineering and scientific principle: First identify and describe the problem, Then look for suitable solutions. The proposal doesn't do a good or credible job of defining and describing the problem, so it's very hard to evaluate the proposed solution(s). I encourage everyone to review the proposal which can be found at: (www.arrl.org/announce/bandwidth.html) and I'd be glad to engage in an off-reflector dialog to gain some enlightenment in what it really means. 73, Fred K6DGW Auburn CA CM98lw K2 #4398 KX1 # 897 (with which I did 34.46 pts/lb in last night's Spartan Sprint) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Forgive me if you've seen this before, but it IS possible to align the K2 so that there is no pitch change when changing filters: You can eliminate the pitch change if you don't mind changing the filter bandwidth slightly. For example, suppose that you have set a filter to 400 Hz bandwidth and located the BFO so that the signal is centered in the filter, and suppose that the result is that the pitch of the centered signal comes out 10 Hz. high. Just change the bandwidth to 420 (or 380) Hz., readjust the BFO to re-center the signal and let the K2's magic algorithm do its work. Chances are it will come out on pitch. I have been able to adjust all of my filters so that there is no change in pitch when I cycle through them. -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K2 Loss of Audio
Denny, I have removed the KDSP2 and jumpered the two headers. I am beginning to think in my case however that the problem is in the P5 connection on the RF board. I lifted the KPA100 up, turned it over and rested it on a stack of books. After connecting the K2 up in this open condition, there was no audio. When I jiggled the female connector to J5, the audio was restored. I am going to operate the K2 for a while in this open condition. If all goes well, I will restore the KDSP2. Maybe I should make a longer audio cable to the KPA100 that doesn't bind when going around the KPA100 shield cut-out. In my case routing the audio cable around the shield may cause this cable to strain somewhat at P5. Roy Morris W4WFBNo virus found in this outgoing message. Checked by AVG Anti-Virus.

[Elecraft] kx1 hotel qrv best antenna suggestion
hey KX1 users out there: what would be the ultimate hotel room antenna (that can be accomodated in laptop bag)? maybe a loop of some kind? I am always flabbergasted by the reports from kx1 users as to what everything they are able to achieve when using kx1 with a random wire, working from a park bench or similar... I have completed my kx1 something like a half a year ago and being a frequent traveller I am since taking it with me on every business trip. Till today not a single qso with a random wire out of a hotel room. I am currently in Yugoslavia. This time an old hotel, no beton walls, no BPL, fourth floor (Hotel Moskva in Belgrade), 10 meter long wire out of the window facing the Balkanska Ulic, two same length wires serve counterpose in the room- and my first qso with this setup, wkd UR5IF, qrb abt 1500 kms, not bad! Mike himslef has been running inly 5W into a LW. One other thing: when I am usisng an indoor antenna and a switching power supply, that worked well for FT817, I am getting three S units more noise, ferrite rings won't help.

[Elecraft] K2: 12m alignment problem
I was doing testing alignment tonight with everything going perfectly until 12m alignment, the very last band on the list. All other bands had no problems during alignment, but with power set at 2.0 W the power output on 12m shows just 0.2 W. Bumping the power setting up has no effect on power output; still 0.2 W. I'm going to start tracing it back to see what I can find. But since I'm just learning my way around the K2 I thought I'd mention it here in case someone can point me to likely candidates faster. Such torture to run into a problem at the very last step of alignment! (Well, it happened on prealignment, too, but I was naively hoping alignment would sort it all out.) Thanks!

RE: [Elecraft] kx1 hotel qrv best antenna suggestion
Sergej, DF6MU asked: hey KX1 users out there: what would be the ultimate hotel room antenna (that can be accomodated in laptop bag)? maybe a loop of some kind? --- Hi Sergej! I'd say that any wire you can get outside of a hotel room would be better than any wire inside. That's because of all the metal in the buildings. Most have a metal skeleton at least, plus wiring, plumbing and more. It sounds like the hotels you are staying in have windows that open. Here in the USA most are sealed shut. Assuming you have an open window, if you drop the wire down, be aware that you don't want it to exceed 1/2 wavelength (actually 5/8 wavelength) because beyond that point the radiation pattern skews upward. I'd shoot for whatever is closest to 1/2 wavelength that the KX1 ATU can handle. The closer you can get to 1/2 wavelength, the higher the efficiency your antenna will have because it won't be dependent upon a good RF ground. Of course, if you can get the wire away from the building, all the better. If you find yourself stuck indoors with no windows that will open, I'd run two wires of equal length away from the rig - one along the ceiling and perhaps the other along the floor.

[Elecraft] K1 / KX1 Zero beat
[EMAIL PROTECTED] wrote : This brings up an interesting question: how do most folks zero beat the KX1 and the K1 without the reference beat available on the K2? Is there a better way than just sort of guessing (my technique so far)? Well on the K1 I usually engage the narrow filter and tune for peak audio signal. That seems to work pretty well for me. On the KX1, I crank the variable filter down to about 500 hz BW and tune for peak audio signal. Note that if you crank the variable filter all the way down the center frequency of the filter will most likely shift down below 600 Hz (it does on mine) so you don't want to set the filter to its narrowest setting when doing this. You can always check at how good of a job you are doing by piping the audio output from the rig into Spectogram or even something like Digipan on your PC as this will give you a fairly accurate reading of the audio frequency.

RE: [Elecraft] kx1 hotel qrv best antenna suggestion
I have had similar issues with using a random wire antenna and the KX-1. The random wire suggested in the antenna tuner manual works for receive, but no one hears me. It is very frustrating to be listening to S-9+ CQs where it is obvious that the sending station hasn't a clue I'm around. I have worked successfully with an MP-1 Superantenna, which can be connected to balcony railings, but I find that it works best if I use an antenna analyzer to pre-tune the antenna. I also use the KX-1 mostly for travel, so a good hotel arrangement would be very useful. By the way, I use the Micro908 Antenna Analyzer kit from AMQRP. Since it also works as an audio DSP filter (same DSP unit as the K2), I can use it for audio dsp with the KX-1 once I have adjusted the antenna. It works very nicely to reduce the ambient noise levels and gives you lots of filter choices.

[Elecraft] N5ESE's T1 review -- excellent, but one correction
Monty, Thanks for comprehensive review of our T1 ATU (http://www.dit-dididit-dit.com/t1_atu.htm). I'm glad it worked well for you in field tests. We may make a few assembly and owner's manual tweaks based on your feedback. (We could have used you as a field tester :) One important comment: There is definitely no need to use stacked cores for both transformers in the SWR bridge. Balance is excellent even with a stacked core at transformer T2 only, because the characteristics of the bridge are set strictly by the turns ratio, which is the same on both transformers (8:1). There is also no need for a stacked core at transformer T1 for power dissipation reasons, since only T2 sees the effect of the voltage step-up and corresponding core heating. We have fully tested the unit at its maximum rated power with just the one stacked core. We did send out an incorrect version of the errata sheet to a few builders that claimed 7 turns were required on T2. Hopefully you got the word to use 8! 73, Wayne N6KR --- http://www.elecraft.com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K2: 12m alignment problem
Mike, There is not much difference between the 10 meter and the 12 meter operation of the K2. Assuming that you are seeing a good peak on 10 meters, your problem is likely connected with the bandpass filter. Check C45, the trimmers C44 and C46, and the relay points of K6 carefully. Other than those components, there is no difference between 10 meters and 12 meters. Check your soldering carefully, then check it again, and if all else fails, check the soldering - that is the most common cause of failure in the K2 kit. If all else fails, you may want to check the VCO frequency for 12 meters - with the dial indication at the low end of the 12 meter band, the VCO should be producing a signal at 19975 kHz (read the frequency in CAL FCTR mode with the counter probe in TP1). If the frequency is incorrect, the problem will be found in the VCO area and not the BPF. 73, Don W3FPR -Original Message- I was doing testing alignment tonight with everything going perfectly until 12m alignment, the very last band on the list. All other bands had no problems during alignment, but with power set at 2.0 W the power output on 12m shows just 0.2 W. Bumping the power setting up has no effect on power output; still 0.2 W.

[Elecraft] K2 Filter Alignment for Mac
Folks, Is there a good program for setting up the K2 filters that will run on a mac with OS X? I do not have OS 9 or Classic, so the article residing on the Elecraft website is not quite what I need. It would be nice to have a similar article based on a program for OS X; is there one? AudioXplorer was mentioned as a possibility; any thoughts on that?
