Re: [Elecraft] CW Key Suggestions
The two levers are independent on an iambic paddle so that you can close either contact or both at one time by squeezing. A Bug, such as the Original has a single lever that allows you to close either contact, but not both at the same time. With an iambic keyer if you close both contacts it will alternate dits and dahs with the first element determined by which contact closes first.

Re: [Elecraft] CW Key suggestions ?
I've had a lot of keys in my 48 years of hamming - and I've kept them all (they are on display in my living room!). For portable use, I've used a Palm Paddle for several years. Very nice, light, inexpensive and works very well. I just replaced it with a Begali Traveller Light. The Begali is excellant, but the trade-off is cost, weight and size. To me the trade-off is worth it. My home key is a Begali Sculpture.

[Elecraft] K3 - improved tuning knob
I abhor spending money when it is not needed. However, I did wish to improve on the feel of the tuning knob. So, I went to the junk box and found a new unused black tuning knob tire from TenTec that fits the K3's stock knob perfectly. You can see the tires (TenTec calls them trim rings) at: http://www.tentec.com/categories/Accessories/Trim-Rings/ I do not recall which one I have, model number wise, but it makes the tuning knob larger in diameter and looks like it grew there.

[Elecraft] FD generator quiet problem
We used the Honda generators at our FD site this year. They were so quiet it seemed like we were on the ac mains! As a solution to the quite problem some others have experienced our club as an old 6 face ac voltage meter out of an old power plant that we could hook up via extension cord from one of the generator outlets and have it at the operating area to indicate whether or not we have ac being generated. Just an idea for next year.

[Elecraft] QRP field day
I hope Jessie will forgive me for reposting his Email, but now that we have a whole year to plan for the next field day maybe now is the time to do this. - From: Jessie Oberreuter Date: Wed, Apr 18, 2012 at 5:14 PM Subject: QRP FD ~ ~ ~ ~ ~ We used to run FD at 100w. Half a dozen years back, I talked the group into trying a QRP FD, and we had mixed results. We switched back and forth a few times, and ultimately found that our scores didn't change, but, in general, we enjoyed the QRP FDs more -- especially once we added PSK31. IMHO, operating FD QRP is actually a lot more fun b/c it's easier to set up and tear down, easier to avoid QRMing your own operators, and, if you traditionally use generators, it's also much quieter. Your contacts are worth more, and we get a kick out of operating simple radios. If you're considering a QRP FD, here are some further points and suggestions for your club's consideration: * Running QRP is a great way to reduce the QRM from your own operators :). * The solar contacts are great bonuses, and those of us with low power radios often find ourselves running solar for most of the day. We have a separate set of power plugs for solar, so anyone who wants to run it can, and we try to each make at least five rather than just making five as a group. * We try to collectively earn a WAS. Not only does this create a group goal (rather than competing for most contacts), it also gives folks an incentive to move on from hard to make contacts and seek out other contact opportunities. * Bring outboard filters if you have 'em -- they can really make a difference. Try different antenna directions and orientations -- it can make a huge difference in background noise. Use of separate tx and rx antennas can also offer a huge improvement in noise reduction, and adding support for split tx/rx to your field radios can be a great club project! Folks often think that a clear, but relatively quiet station won't hear a QRP signal. Don't be so sure! It's S/N, not power, that makes the difference :). The more stations you can hear, the more stations you can potentially work! * Don't forget the digital modes! PSK31 has been serving us well. Don't forget VHF! A 6m opening can be a life changing experience! Don't forget local contacts on 80m. You don't need to have a huge antenna and you don't need to fight the QRN -- just make occasional passes to collect locals. Also remember that VHF isn't just 2m FM and a mag-mount. If you have a 6m or 2m SSB radio to spare, bring it, and scare up a beam or make a simple quad -- your tech who would otherwise be trying to scrape up a dozen 2m FM contacts with an HT will love you! Remember: horizontal polarization! * Be willing to work different bands. Some folks have pet bands that they just won't leave even when they're not having much success. We've also had folks actively avoid 20m SSB because it just seems like too much of a bedlam. Again, good filters, directional antennas, and the RF Gain knob can make a huge difference! * Mentor less experienced ops -- a few simple practices can go a LONG way towards making contacts more successful. Sometimes it's knowing how to exchange numbers in other ways than just repeating 3A 3A (eg one, two, three alpha), how to use attenuation, how to note when a station is clear but too busy to hear you, move on, and try again later. These are great points of education for members who may have never developed such skills because they've never needed to. * Leave the big shack radios in the shack :). One of the things that can make FD stressful is having to tear down the home station, pack it into a hostile environment, pack it back, and then rebuild the shack. Many of us have our shack radios and also have several field radios that we might not otherwise consider for FD because they are lower power rigs. If you're operating a QRP field day, you can leave the home shack intact, and just bring your field radios which are also more accustomed to being abused. Our FDs used to be something of a show of force, where folks would seemingly bring every piece of radio equipment they owned. Now, we try to do the opposite and typically pack complete stations in laptop and camera bags. Having extra field rigs in your ranks can also be great for newer members who a) may be more afraid to bring their nice base rigs into the field, and b) often really appreciate the opportunity to operate other kinds of radios. * With smaller, low power field radios, it's much easier to pack for camping as well as operating. Small radios, batteries, solar chargers, and headphones all around makes
[Elecraft] all Elecraft FD entry

Re: [Elecraft] Firmware final?
Wolfgang, If by final you are referring to the number 4.51 - that number is final right now - if there are any changes made, the number will be changed. If the beta test is successful, that same version will be declared release level - but the code3 will be unchanged. So, bottom line, if you are having success with 4.51, continue to use it. 73, Don W3FPR On 6/26/2012 3:30 AM, Wolfgang -DK9VZ- wrote: Hi current beta firmware 4.51 did show great improvements in WPX CW contest.

[Elecraft] [K3] Gain to KXV3 wideband IF output
I've finally completed my Soft Rock for use as a pan adapter. However it is
rather deaf.
On investigation, my measured gain from the K3 antenna input to the KXV3
IF output (terminated in 50 ohms) is -20dB. Looking at the K3 block/circuit
diagrams, this would appear to be on the low side. Is this typical or do I
need to conduct an internal examination.

[Elecraft] KX1 KXPD1 (was Re: CW Key suggestions ?)
Phil : Where the KXPD1 is really useful is if you ever decide to operate portabl somewhere without a table (i.e. sitting in a lawn chair etc). The nice thing about the KX1 / KXPD1 combo is that you can easily use it on a clipboard in your lap with the rig / paddles on top. I have a clipboard that is big enough to hold legal-sized paper and it makes a great lap-desk for portable operating, sitting on the ground or in a camp chair . If I put a few sheets of paper on it then I can just jot my notes down beside the rig and copy them to a proper log later. Likewise I have used the same combo while operating from my car, with either a mobile antenna or a portable antenna adjacent to the car. You could still use a separate paddle with the clipboard but it is very convenient to have the all-in-one package as it has a very small footprint.

Re: [Elecraft] KX3 Utility Memory Editor

Re: [Elecraft] FD generator quiet problem
Since the concern is that a quiet generator will run out of gas and nobody will know (those folks using AC = Charger = Battery = K3 setups), how about this instead? The EU2000 will run for more than 24 hours on an external 6 gallon tank of gas under full load. If you use that setup you don't have to refuel every 4 to 6 hours, which means no spilling gas, fumbling in the dark, or worries about running out of gas during the contest. You can use a standard portable 6-Gallon gas tank ($50 from WalMart) with a primer hose and fuel connector for an outboard motor (like a Johnson). You then replace the standard Honda gas cap (the one that as the ON/OFF air vent), with a special cap that has the mating connector for your outboard motor on it. As gas is drawn out of the generator tank, the vacuum it produces draws gas from the 6-gallon tank back into the generator tank. You fill up the Generator tank and 6-gallon tank at a gas station before the contest, then just plug the stuff together in the field, start it up, then turn it off when the contest is done. Expect 24-28 hours of run time at full load, and a couple of days at partial load. Google Honda Generator Extended Run Gas Cap An example of a complete assembly (tank, fittings, hose, cap) is here: http://www.wisesales.com/bergs-6-gal-system-for-honda-etq-generac-all-power.html#.T-nNl5GDl8E An example of the cap-only is here: http://www.ebay.com/itm/HONDA-Eu2000i-GENERATOR-EXTENDED-RUN-FUEL-CAP-SYSTEM-/170855572266?pt=BI_Generatorshash=item27c7c9232a I used a setup like the one I described for several days after we lost power during a hurricane late last year. Because I was only drawing a few hundred watts (a few desk lamps and our refrigerator), it ran for 2 days before I put more gas into the external tank, which was about six feet away from the generator -- so I didn't even stop the generator. 73, Bob, WB4SON (Love my Honda and K3; two things that just work right all the time) __ 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] CW Key suggestions ?
I like the Navy flameproof 26003 for portable straight key operation. Like the J38 it is meant to be screwed down, but I mounted mine on a rectangle of Lexan, which gives me a fairly light and stable key with contacts shielded from easy contamination. It also appears to be a fairly rugged design. You can still get New Old Stock from J. Bunnell for about $80, and used ones for less elsewhere and on ebay. It has a nice feel, very similar to the Junkers key I use at home. One key I don't like is the Chinese army K4.

Re: [Elecraft] KX3 Field Day observations
Wayne, In an earlier response I indicated that that I might not have understood. I didn't! I was so out of it from FD that I probably made little sense. I did discover APF during some familiarization in my shack. We did not use it during FD as I had totally forgotten about it during the hectic goings on. I have rebuild my home shack and am kicking myself for having forgotten about this feature. During my few days of familiarization at home, I found APF to be quite useful. As I think about it, I suspect operator fatigue would have been less had it not been for this oversight. I suggest every CW operator who has this feature on his radio, whether using a KX3 or not, to use it. It really can clean up noisy signals. Sure wish we had you on our site.

[Elecraft] K3/KX3 Operating Tip: APF (audio peaking filter) for weak-signal CW work
Both the K3 and KX3 have an APF control (audio peaking filter). APF can be extremely effective when you're trying to copy weak CW signals buried in noise. Most DSP filters have very steep skirts; they're often referred to as brick-wall filters for this reason. This is the type of filtering associated with the WIDTH control (K3) or PBT control (KX3). In contrast, the APF is a filter with a very narrow peak (about 30 Hz at the -3 dB points) and very broad skirts. The narrow peak brings up the signal amplitude slightly, while the broad skirts prevent noise from being amplified and delayed in such a way as to dominate the signal. The APF function used in the K3 and KX3 is a modern DSP reinterpretation of the hardware APF circuit found on some legacy transceivers, which was very effective. On the KX3, the APF switch is labeled APF (tap), while on the K3, it's labeled DUAL PB (hold). The K3 actually provides two different special filter functions; use the DUAL PB menu entry to set up the switch for APF. When you turn on APF, the DSP graphic changes to remind you of the nature of APF, with its narrow peak and broad skirts. I suggest setting the passband width to about 250-300 Hz when using APF. The DSP graphic still shows an approximate representation of the width even with APF turned on. 73, Wayne N6KR __ 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] KX3 first impressions
I calibrated the KXFL3 (using my XG3) last night and all went well (quite the involved procedure but instructions are without fault). I did some listening Monday with the internal speaker and that takes some adjustment from what I hear using my K3 (10-inch National speaker from the 1950's). Not a fair comparison. I will probably either use headphones or ext speaker most of the time. I connected my computer (H/K) speakers and less harsh sound. Getting acquainted with the little radio with manual open. Listened to a net on 14.290 this morning. Haven't tested the radio with meters, yet. I got to scoot up the tower before it rains again to fix my TR line for my 222 and 432 antennas. Interesting way the filters switch. Passband tuning is a bit different. I had an initial antenna issue which looked like a bad cable on the BNC but turned out a bad exterior coax. Auto-tuning looks like it is working. Next it to pre-program the memories for my favorites (will try copying my K3 list). Thanks for making the cutest ham radio! I got lots of folks looking forward to my Hamfest demo 14July. Over the 4th I will begin looking at SDR I/F control wiring. 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 50-1.1kw?, 144-1.4kw, 432-QRT, 1296-?, 3400-?

Re: [Elecraft] Fusing the K3 Power Line
Hi Lee, The manual (rev D10) doesn't really say 25A fuses, just that the power supply should be rated 25A and that two fast-blow fuses should be used in the supply cabling for protection. I use 30A fast-blow fuses, one in each of the pos and neg lines. Power comes from a battery, and the battery is solar-charged. Matt Zilmer Consultant - Product Management Dept.

APF can be extremely effective when you're trying to copy weak CW signals buried in noise. Most DSP filters have very steep skirts; they're often referred to as brick-wall filters for this reason. This is the type of filtering associated with the WIDTH control (K3) or PBT control (KX3). In contrast, the APF is a filter with a very narrow peak (about 30 Hz at the -3 dB points) and very broad skirts. The narrow peak brings up the signal amplitude slightly, while the broad skirts prevent noise from being amplified and delayed in such a way as to dominate the signal. The APF function used in the K3 and KX3 is a modern DSP reinterpretation of the hardware APF circuit found on some legacy transceivers, which was very effective. On the KX3, the APF switch is labeled APF (tap), while on the K3, it's labeled DUAL PB (hold). The K3 actually provides two different special filter functions; use the DUAL PB menu entry to set up the switch for APF. When you turn on APF, the DSP graphic changes to remind you of the nature of APF, with its narrow peak and broad skirts. I suggest setting the passband width to about 250-300 Hz when using APF. The DSP graphic still shows an approximate representation of the width even with APF turned on. 73, Wayne N6KR __ 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 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

I suspect that this discovery might have caused some concern, because the B was designed for secure comms between tanks no more than 800 yards apart - according to our Instructor.

Re: [Elecraft] QRP field day
All excellent suggestions! See other comments below: On 6/26/2012 5:37 AM, Robert 'RC' Conley wrote: * We try to collectively earn a WAS. Not only does this create a group goal (rather than competing for most contacts), it also gives folks an incentive to move on from hard to make contacts and seek out other contact opportunities. I've always found it fun to try to work a clean sweep of all of the US and Canadian sections, even though there is no award for doing so as in Sweepstakes. * Don't forget the digital modes! PSK31 has been serving us well. Don't forget VHF! A 6m opening can be a life changing experience! Don't forget local contacts on 80m. You don't need to have a huge antenna and you don't need to fight the QRN -- just make occasional passes to collect locals. Also remember that VHF isn't just 2m FM and a mag-mount. If you have a 6m or 2m SSB radio to spare, bring it, and scare up a beam or make a simple quad -- your tech who would otherwise be trying to scrape up a dozen 2m FM contacts with an HT will love you! Remember: horizontal polarization! Two friends and I operated 6m/2m SSB/CW QRP one year at our QRP Field Day and had a great time! From 7,000' ASL we had a nice shot directly up the Central Valley of California, with a number of large cities from Bakersfield up to Sacramento. If we relocated our FD site up another 1,000' we would also have a clear shot to LA/OC/SD and the Inland Empire. But getting to that site is a challenge. It's on a ridge at the top of a ski run. It wouldn't be as convenient to run into Wrightwood for supplies or meals, so we'd have more to pack in. Also, usually it's cold and windy enough where we usually operate. * Leave the big shack radios in the shack :). One of the things that can make FD stressful is having to tear down the home station, pack it into a hostile environment, pack it back, and then rebuild the shack. Many of us have our shack radios and also have several field radios that we might not otherwise consider for FD because they are lower power rigs. If you're operating a QRP field day, you can leave the home shack intact, and just bring your field radios which are also more accustomed to being abused. Our FDs used to be something of a show of force, where folks would seemingly bring every piece of radio equipment they owned. Now, we try to do the opposite and typically pack complete stations in laptop and camera bags. Having extra field rigs in your ranks can also be great for newer members who a) may be more afraid to bring their nice base rigs into the field, and b) often really appreciate the opportunity to operate other kinds of radios. Until recently I would have subscribed to this advice, but one of our group has brought his K3 to the last two Field Days. While the K3 wasn't necessarily designed for portable operation in the sense of the KX3, it served our 20m station well. The fact that there are so many K3s that go on DXpeditions attests to its durability. However, it ran off a 100-Ah battery that was charged by solar means. Weighing 95 pounds, I understand that it took two guys to lug it to the tent. But at 5w, it would run for a long, long time.

Re: [Elecraft] Fusing the K3 Power Line
Lee your K3 is protected from over current in a number of ways. The worst case I can imagine in your shack is a heavy metal object falling across and shorting the unprotected power leads to the K3. I have had this happen. To protect against this you place fuses at the battery. Your Astron has foldover current limiting so it is also self-protecting but if it is connected directly to the battery you will need a second set of fuses at the battery to protect the charging circuit from reverse feeding a shorted cable. I think the Astron primary is already fuse protected. You have already indicated you have grounded everything in your shack. If that includes the negative of your battery then there is no need to fuse the negative since you have provided a shunt path around the negative fuse. A word about fuses and fuse holders. Buy the best quality available and that usually means buy American. Fuse holders are probably the least reliable component in your system. Fuse are the second least reliable. Use only spade type fuses (that's called a faston connector). Protect the assembly from heat and moisture. Clean up any corrosion with a baking soda paste and a toothbrush. Remember a bad fuse is one that doesn't fuse at its rated current. A good fuse is one that fuses at its rated current. No wonder there is so much confusion about fuses. 73, Fred, AE6QL -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Lee Buller Sent: Tuesday, June 26, 2012 1:57 PM To: Elecraft Reflector Subject: [Elecraft] Fusing the K3 Power Line Reading the manualit says that two 25 amp fuses should be in both the positive and negative leads going to the K3 from the battery.

[Elecraft] K3 intermittent speaker connection at FD
My K3 did a great job at Field Day, as in previous years. A slight embarrassment was caused when one of the speakers went silent, and the operator had to jiggle the 3.5 mm stereo plug to get the sound back. It is not the first time for me, but the first time someone else using the radio noticed it. When I first got the radio I was lazy and started using a Radio shack cable that splits off into two RCA female connectors, and that cable has stayed with the rig since. Generally I like to make my own cables, but that would require some suitable wire that is small enough. I like using RG-174 for purposes such as this, and maybe with a suitable plug double RG-174 could be used. Anyway, my guess is that the problem with the old cable is oxide and/or a poor mechanical fit of the 3.5 mm plug. I know that the subject of quality plugs was discussed recently, and I will be able to find those posts. Did anybody use those quality plugs with double RG-174? Or with some other type of cable that makes it easy to split the channels at the other end? Or is there a ready-made Y cable available like the one I have, but very reliable when used for K3 stereo speaker connection? Thanks in advance. 73, Erik K7TV __ 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] The ins and outs of PSK on the K3?
I have been running PSK for a couple of months now on the K3 and am wondering if I am using it in the best way. I am using DM780 that comes with Ham Radio Deluxe and I usually set the K3 in USB and pick the stations from the waterfall. I also have a P3. Up until now, I have been using the 2.8 KHz filter setting and have had AGC on. It always seemed that there were two flaws in this: One was that it was not easy to pick the actual signal using the P3 markers, you always were using the USB lower frequency point that was some number of hz away from the signal. The second was how do you get an actual frequency for the signal instead of just 14.070 (20M)? Sometimes you can see stations spotted at 14.072 but finding it was always a search of spots one by one. Today I played around a bit. For one, I used the manual notch filter to remove a really strong signal. I turned of AGC. This works well. I also set the radio in DATA mode instead of USB. The nice thing about this, is that I can use the P3 with a +/- 2 KHz span, and see all of the signals in the usual PSK range, but now I can click on one I see, and it will actually center it in the passband and give me a frequency readout that seems better than the standard 14.070 for 20m. Furthermore, I can use a narrower filter and the reception seems much better and the decoding more accurate. So my question is, is my new found way of using the K3 a better way and possibly the best? Thanks for any insight.

Tom, There is nothing wrong with the way you are doing it - and works well for anyone having a panadapter display to work with (P3 or LP-Pan) With that you can narrow up the filters and eliminate interference. If you do it that way (tune the K3 to the signal desired rather than clicking on a waterfall), then you may want to investigate using the K3 Utility terminal rather than DM780 if all you want to decode is PSK31 or RTTY, or you might want to investigate Fldigi and give the K3 polling (and your computer reaources) a rest. OTOH, there is a convience to using that full SSB bandwidth (but in DATA A submode) along with a waterfall display. Click on a signal on the waterfall, the K3 frequency does not change, but the PSK31 application shows you the frequency of the signal. Yes, using that wide bandwidth, you would want to turn AGC off, or if that is not desirable, turn the RF gain down as required - the soundcard application filters are plenty good, but strong signals within the bandpass will pump the AGC and change the gain of the receiver. One problem with HRD/DM780 is that it does not properly recognize the K3 data submodes and will force your K3 to USB if you allow it to do whatever it wants - you can change the mode manually to DATA A, but that is a pain. I gave up on HRD for exactly that reason. I use Fldigi with RigCAT selected. 73, Don W3FPR.

It always seemed that there were two flaws in this: One was that it was not easy to pick the actual signal using the P3 markers, you always were using the USB lower frequency point that was some number of hz away from the signal.

The nice thing about this, is that I can use the P3 with a +/- 2 KHz span, and see all of the signals in the usual PSK range, but now I can click on one I see, and it will actually center it in the passband and give me a frequency readout that seems better than the standard 14.070 for 20m. Furthermore, I can use a narrower filter and the reception seems much better and the decoding more accurate. So my question is, is my new found way of using the K3 a better way and possibly the best?

Re: [Elecraft] Fusing the K3 Power Line
A better way to say it would be A good fuse is one that meets its written specifications. They aren't all guaranteed to ever blow at their rated current. Some are, some aren't. Looking one up at random on littelfuse.com just now, I found time to open specified as: 150% of rating, max 30 minutes 300% of rating, max 10 seconds Another one says 100% of rating, min 4 hours 135% of rating, max 1 hour 200% of rating, max 1 second Circuit breakers are rated similarly. Remember, nothing is 100% accurate or 100% perfect, so there has to be some slop somewhere. 73 and thanks for listening, Carl WS7L Mr Pedantic -Original Message- A good fuse is one that fuses at its rated current.

Did anybody use those quality plugs with double RG-174? Or with some other type of cable that makes it easy to split the channels at the other end?

Re: [Elecraft] The ins and outs of PSK on the K3?
Hi, I did try what you suggested, but on the P3 when you use data a mode, if you click on a signal on the P3, the marker is way outside the filter region. It seems if you put the K3 in PSK-D mode and use the P3 (and soundcard) then what you click on is pretty well in the middle of the waterfall and you can zero in on it quite well. Things sound a little funny though, compared to USB or data A. Is this a normal situation? -- View this message in context: http://elecraft.365791.n2.nabble.com/The-ins-and-outs-of-PSK-on-the-K3-tp7558230p7558238.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] Really old receivers
A buddy and I both had one in the 1950's. Yes, we chirped our way onto 40 meter CW with them but most challenging was using that 220 MHz modulated oscillator transceiver built in for tank-to-troop walkie-talkie contacts. It is tuned by the vertical thumbwheel on the left part of the panel. 73, Ron AC7AC -Original Message- Does anyone else remember or have a Wireless Set Nr. 19? Built during WW2 for the Canadian Army Armoured Corps and our Soviet Allies [it had Russian and English markings], it was a transceiver, weighed a lot, and I cut my teeth on one. Covered ALL ham bands [between 2 and 8 Mc/s]. Most repairs could be made by dropping it on a hard surface. [Other than that, I don't have a good thing to say about the old beast.

Re: [Elecraft] random wire and the KX3 ATU
Jeff, The KXAT3 has a very wide tuning range and is specifically designed for use with random-length antennas. Typically any wire longer than 20' or so can be tuned up on 40-6 meters. A 74-foot antenna will probably be tunable to reasonable SWR on 160-6. A random wire antenna can work very well -- comparable to a vertical or dipole depending on the band, radiation angle, and your ground system (if the random wire is worked against radials). I use random wires almost exclusively. The KXAT3 does an excellent job with them. It will also do other magic tricks like make an 80-meter dipole work on all bands, or a 20-meter yagi work on 30-6 meters, etc. Efficiency will vary, but the transmitter will be happy. 73, Wayne N6KR On Jun 26, 2012, at 7:55 PM, Jeff Herr wrote: I know folks who have had bad experiences using a random wire with an ATU.

[Elecraft] CW keys? CW OPS!
Whatever key, or keying device, one chooses, good technique is paramount. Optimally, the operator receiving your code will have no idea what particular device you are using, and this is true even with bug-key sending, if sent with machine precision. I do not say this is easy. Good code, sent by hand – and all good code must be sent by hand, for who evaluates the timing and fluency of a computer- is the only aesthetic element of CW shared by both sender and receiver. This is important for there are many aesthetic elements of Morse code; there is the pleasure of un-boxing a new key and feeling the finger pieces for the first time, the first taste of spring tension on an antique bug, that first test of continuity in the mechanical train and the feeling that a great friendship, or even romance has begun. Then, there are the hours. Hours upon hours spent at the oscillator sending names from the phone directory or the titles of books on the shelf. The striving for perfection while intoxicated by the sweet rhythm of characters dwelt over, isolated, sent fast and slow, in pieces and parts until, a thousand times and still not just quite…yes there it is now. Perfect! This is too rich a gift to be hoarded. So, to the ether we go! And now, and only now, does the true shared aesthetic experience become possible. We answer a CQ by mustering our very best, well practiced and expectant characters for the examination of friend. It is just as we had hoped: the characters flow nicely, the propagation holds, a nice chat ensues, and finally our friend signs clear with appreciation and a recognition of our hard work, now evident. “GUD FIST”. Code is a gift, and whether a solitary solace or shared experience, it takes hard-earned technique. As in all things, excellence is as difficult as it is rare. For my part – I’m back to the oscillator with any old key I can find… 73;Jake K4JQV __ 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] random wire and the KX3 ATU
As an example, I used a 40m Extended Double Zepp for field day. This is an 180' wire center fed with ladder line. My FD installation had about 60' of ladder line hanging down to the rig. Ordinarily, I would use a toroid to make a balun to the rig, but I didn't have a suitable form in my junk box, so I hooked the ladder line to a BNC to dual banana binding post adapter. The KX3 ATU did fine in matching from 80 to 10m, except on 40m. On the other bands, the match was 1:1 or close, but on 40m, the tuner struggled to get down to 3:1 or so. I added a 33' radial wire to the ground side of the banana adapter and ran it under the antenna, keeping it 2 to 3' above the ground. With this addition, the ATU could usually get close to 1:1 on 40m. The antenna seemed to play well, so the efficiency must not have been too bad.
