Re: [Elecraft] K3 and N1MM Logger Configuration Rosetta Stone

I do that a lot. It works great. I select Config Ports and have the settings under the Hardware Tab as Always CW What that check means is use this port to send CW and Don't Change Radio Mode. I have both of the top boxes checked. There are special reasons for certain contests where you might want to change that. Under the Hardware Tab I select K3 for Com1 Good. Although, if you're not sure that the port you're using is really com1, check it out. I've had laptops that put com1 only on a port extender and com2 on the computer itself. with DTR(Pin4) and RTS(Pin7) both set to Always On as suggested by the N1MM information displayed. TILT! There's your problem. I'm assuming you want N1MM to send CW. To do that, left click on the Set button for COM1, then choose CW for DTR (pin4). To run only CW, choose Always Off for RTS (pin 7). If you want the computer to send PTT to the radio, choose PTT for RTS(pin7). With DTR Always On, the serial port won't send CW. With RTS(pin7) Always On, you'll be stuck in Transmit if you set the radio for PTT on RTS. Now, go to the Config Menu of the K3 (with a LONG button press for the second menu) and go to the PTT-KEY setting. To only run CW, set this for OFF-DTR. To run both SSB with PTT from the computer and CW from the computer, select RTS-DTR. [This is a WONDERFUL feature built into the K3 -- you don't need the transistor between the DTR and the key jack, or between the RTS and PTT. The K3 takes CW directly from pin 4 and PTT directly from pin 7 -- IF your CONFIG setting tells it to do so. Now, I'll tell you what I do. On CW, I run QSK with the K3. Follow the K3 manual to get there. If you plug a paddle into the radio you can interchangeably use the paddle and computer keying. For SSB, RTTY, and PSK, I use VOX, NOT PTT. For RTTY and PSK, I feed audio from the computer sound card to the radio, and from the radio to the computer sound card. So I don't use PTT (RTS) at all. Some guys like to use PTT, that's your choice. I'm a serious contester, and VOX works for me. BTW -- if you set N1MM to do both CW and PTT, you can still turn off CW or PTT or both with the CONFIG setting for PTT-KEY. 73, Jim Brown K9YC __ 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] K3 going mobile?
I have used my K3 a number of times operating mobile but not on the run. That means I let the rig stand on the floor and bring it up when my car is holding. The performance is very good with a direct connection to the car battery, fuses in both + and - for obvious reasons. No interference to or from the car (a Volvo XC70) with the battery hidden below deck in the aft cabin.

Re: [Elecraft] Elecraft Sales service goes from bad to worse
I would agree that your criticism is somewhat inappropriate Julian, Elecraft still do an excellent job especially since they deal with a very much greater customer base these days. A couple of points worth commenting on though. I recently ordered some upgrades for my K2 (yes some of us still use those...). Confirmation of order and dispatch was very quick. A few days later the tracking at UPS after it had left customs also showed they attempted to deliver but clearly had not. In fact what happens is that Parcel Force send you a postcard to instruct you how to pay the customs fees and that time corresponded to when they had sent that postcard, not when they delivered (the postcard, with a different Parcel Force tracking number, arrived the next day and I paid and arranged delivery for the following day). There were a couple of small omissions in the parcel, so guess Elecraft do sometimes make mistakes. An email to sales resolved these, the missing parts were dispatched the same day and received here yesterday. So apart from that slight hiccup I am a very satisfied customer. 73 Dave G3YMC K2 #2498 -- View this message in context: http://n2.nabble.com/Elecraft-Sales-service-goes-from-bad-to-worse-tp2489040p2490003.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] Elecraft Sales service goes from bad to worse
The happy story. I ordered the KRX3, KVX3 Additional filters etc on the Tuesday and the parcel arrived on the Thursday, yes 2 days from ordering to receiving the parcel by UPS at my works address. I was amazed and the order was all correct. My second order has just arrived for some additional filters, 2 weeks from order but this was due to one part being out of stock and I was ask if I wanted the order part shipped within 24hrs of raising the order, I declined and the parts again arrived within 2 days of being shipped Via UPS, Again the order was all correct and because of the delay the shipping cost was waived.

Nearly 3 weeks ago I ordered a KXV3 and a couple of hardware upgrades for my K3. I paid using PayPal, accepting the USPS charge which was nearly half the cost of the actual order. When nothing was received for such a long time I obtained at the end of last week the tracking number from Elecraft Sales and was able to determine that the package had been stuck in customs for several days and had just been released. When nothing was delivered again today I used the tracking number again and was informed that they had attempted to deliver at 12:28 today. Except that my wife and I had been in all day and no-one had tried to deliver anything. I contacted Sales again to find out if they had given me the right tracking number, and eventually received a reply containing the details they had given for shipment. One vital line of the address (house number, street name) was missing, the phone number given bore only a 60% correlation with mine, and the email address was an old one with one letter missing so it wouldn't have worked even if it had still been available. I really don't know how much clearer I could make my order than to send it via PayPal which includes my confirmed shipping address as part of the standard email. Once upon a time you could order something from Elecraft and it was here in a few days. It seems to be becoming increasingly slow, expensive and error prone (last year I had to remind sales twice before they sent back-ordered items.) I'm afraid this is the last time I order anything from Elecraft. - Julian, G4ILO.

Re: [Elecraft] K3 Time for Users of XP Home?
Julian, G4ILO wrote: I recently posted to the list recommending a program called NTP for Windows. I cannot see anything in the documentation for it to suggest that it won't run on the Home version of XP, although I only have the Professional version so I haven't tried it. I first used the reference implementation (which is what NTP for Windows is), on Windows, on NT 3.5. It is possible that support for 3.5 has been broken in later versions, but it should certainly work on all recent versions of NT, and XP is just a version of NT. (I'm not 100% sure if the Meinberg installer has been modified for the more restrictive directory choices imposed by Vista - most professional users are trying to stick with XP.) As I missed last time, and Julian has hinted at, a proper implementation of NTP, like this, uses adaptive polling intervals, so, with the default configuration, will start at 64 seconds and increase to 1024 seconds, if it thinks that that will give the best compromised between phase and frequency error. -- David Woolley The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio List Guidelines http://www.elecraft.com/elecraft_list_guidelines.htm __ 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] Elecraft Sales service
OK - what service did Elecraft use to ship your package? There are several options at different price levels, so let's get specific. Did they use: Express Mail International? Priority Mail? First Class Mail? Parcel Post? Discussion of these issues requires that we not only say Post Office - but denote the specific service used. Each has their drawbacks. EMI is the only service from the U.S. Post Office with tracking of your package (and it is poor compared to that with UPS, Fedex, or DHL) and full insurance coverage. Regarding UPS, the rates for UPS are very competitive with the Post Office, if a properly negotiated rate plan is in place with UPS. From the U.S. to portions of the U.K. it can be within a dollar or two either way. To other countries, the same cannot be said. So, which service did they use for this package, and what was the real reason the package was delayed? -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of Julian, G4ILO Sent: Tuesday, March 17, 2009 5:22 AM To: elecraft@mailman.qth.net Subject: Re: [Elecraft] Elecraft Sales service Jon K Hellan wrote: Julian, G4ILO wrote: It remains true, in my opinion, that it is taking longer and costing more for us in Europe to order things from you.

Re: [Elecraft] K3 going mobile?
The only minus of K2 IMHO in mobile environments is size. Otherwise it seems be less immune to RF and with excellent speech processor it should offer average power 2-4 times higher than mobile radios. Also if you have AT, it may help with fast adjustments within the band. Instead of using heavy wires it may be sufficient to the cigarette plug with the MFJ conditioner, which contains supercapacitors. Much less hassle.

Re: [Elecraft] Tuning Pulser with K2
Steve, If you recall, it takes about 3 dot intervals (at 20 to 25 wpm) for the K2 to come up to the requested power after a band change, so what you are seeing is the result of your short pulses with longer intervals in between. The K2 power controls may not have time to react with the short pulses. Out of curiosity, why are you not just sending a string of dots? It seems the 'pulser' is a device that could be used for those who do not have keyers. 73, Don W3FPR Stephen W. Kercel wrote: Don: I'm glad to hear from you on this. I talked to Scott at Elecraft earlier in the day, and he said that he had never heard of anyone using a tuning pulser with a K2, but that if anyone would understand the possible quirks it would be you. In addition to the one bar less than normal keying, I have discovered another quirk. If I change bands, and then try to run the pulser, the transmitter does not key. I hear the side tone, but the K2 power meter shows no bars. Also, the peak reading Watt meter in series with my dummy load shows no RF output. I can remedy the problem by reverting to the regular keyer and tweaking the power level between QRP and QRO levels. Somehow this seems to reset something in the rig. Once it transmits at regular keying speeds, if I subsequently go to the tuning pulser, then the K2 will transmit the pulses. I have not yet looked at the RF output on a scope. What I have noticed is that once the transmitter does turn on, the peak reading Watt meter in series with the dummy load gives me about the same peak reading both for the pulser and normal keying. These various quirks do suggest to me that the the 12 ms on interval is too short for the K2 to respond properly. Thus, your suggestion of doubling the on interval sounds like a good possibility for sidestepping these quirky behaviors. Both the on and off durations are determined by a 0.1 uF capacitor in the timing circuit of the pulser. If I change the capacitor to 0.18 uF (values of 0.2 uF seem hard co come by), it would change the on interval to 22 ms and preserve the 33% duty cycle. Unfortunately, the local Radio Shack does not carry these values, and I'll need to order a new capacitor from Mouser. Thus, it will be a few days before I can give this modification a try. I'll let you know how it turns out. BTW, for those who are curious, the Web page describing the pulser is http://www.somis.org/D-a-09.GIF The version that I built is the one transistor version. TXN 73, Steve Kercel AA4AK Don Wilhelm wrote: Steve, I have not yet seen an answer on the reflector, so I will offer some comments. First, I do not think your pulser will hurt the K2 in any way. Secondly, I am at a loss to know why you do not see as many bars in the K2 LED display as you do in TUNE. The bargraph is relatively fast responding and should indicate the power level being transmitted. It may be that your pulser ON duration is too short and it causes a 'flicker' in the display that is not seen by the eye. It would be interesting to see what an oscilloscope connected across the K2 output would reveal (the oscilloscope display would react in even less time than the bargraph). So, bottom line, you may be seeing a natural result of the pulser ON time rather than an actual fault of the K2. Is there an easy way to double the ON time for your pulser? I find it hard to believe that 24 ms of ON time would cause any problems for your amplifier - it certainly would not pose any problems for the K2. 73, Don W3FPR Stephen W. Kercel wrote: Elecrafters: I built a tuning pulser to use with my K2/100 to tune an external linear amplifier. The pulser is the AG6K design. The pulse is 12 ms on and 24 ms off, and repeats about 28 times per second. This is (by design) much faster than the normal 25 wpm or so keying out of the keyer. The interface between the pulser and the K2 is a 2N NPN transistor used as a switch. The key line to the K2 is connected to the collector of the transistor (nothing else is connected to the collector), the switching data comes in through the base, and the emitter is grounded both to the ground side of the pulser circuit and the ground side of the keying line back to the K2. I notice what seems to me to be an odd phenomenon when I key the K2 with the pulser. When I first switch on the pulser, the power level in the little LED power meter on the K2 shows the same power level as I get in normal keying. However, after the first instant, the power level indication drops one bar lower (and then stays there as long as the pulser is on) than the power level indication under normal keying. This effect occurs independent of the power level that I set. It happens with the K2's 100 Watt amplifier both in and out. Is this simply an artifact of the metering circuit caused by the peculiar duty cycle of the pulser?

With RTS(pin7) Always On, you'll be stuck in Transmit if you set the radio for PTT on RTS. Now, go to the Config Menu of the K3 (with a LONG button press for the second menu) and go to the PTT-KEY setting. To only run CW, set this for OFF-DTR. To run both SSB with PTT from the computer and CW from the computer, select RTS-DTR. [This is a WONDERFUL feature built into the K3 -- you don't need the transistor between the DTR and the key jack, or between the RTS and PTT. The K3 takes CW directly from pin 4 and PTT directly from pin 7 -- IF your CONFIG setting tells it to do so. Now, I'll tell you what I do. On CW, I run QSK with the K3. Follow the K3 manual to get there. If you plug a paddle into the radio you can interchangeably use the paddle and computer keying. For SSB, RTTY, and PSK, I use VOX, NOT PTT. For RTTY and PSK, I feed audio from the computer sound card to the radio, and from the radio to the computer sound card. So I don't use PTT (RTS) at all. Some guys like to use PTT, that's your choice. I'm a serious contester, and VOX works for me.

Re: [Elecraft] 43' Vertical and the K2 tuner
Where Gotham stumbled badly was in promoting the fiction that radials weren't required on an (electrically) short vertical. To quote from Gotham's January 1959 QST ad: Are radials needed with a Gotham vertical? Answer: No, except in a few rare occasions. 99% of the installations are done without radials. That ad is disingenuous at best. Notice that the example given does not prove radials are not needed. It only claims that few people used them, and it fails to mention those who used them without radials, especially on the lower frequency bands, got the results anyone familiar with antenna theory would expect. The word abysmal comes to mind. Remember that back then it was still widely believed that a ground rod was a good RF ground, especially if one surrounded it with a trench filled with rock salt to make the earth more conductive. Gotham stepped farther over the edge in other ads, such as their December 1959 QST ad in which they trump the success of K6INI who reportedly worked DXCC using a Gotham V80 running 65 watts input (40 to 50 watts output) CW with 589/599 reports from every continent. The side panel clearly says with a big bullet No radials required. What they did not say was what bands K6INI made these contacts on or whether he had radials on his antenna. A 16 foot radiator isn't a terrible radiator on 20, 15 or 10 meters even with a poor ground. It was certainly better than a mobile whip on a car which many Hams were using to work DX in those days in the midst of the world's biggest sunspot cycle. Clearly, many Novices took Gotham at their implied word and attempted to use the V80 on 80 and 40 meters without radials, which was a disaster. There is a lesson in all of this: basic antenna theory has not changed since radio was invented. There have been no scientific breakthroughs in antennas since Hertz demonstrated a half-wave loop or Marconi figured out how to achieve synchronicity (resonance) with an electrically short antenna. All the work since has been applying different ways to achieve the best results, but always following the same basic rules. The ghost of Gotham lives in any manufacturer claiming a scientific breakthrough or magic from a small antenna. Ron AC7AC -Original Message- Steve and All, Well, not exactly! You remember those Gothams huh! I had one of them. Back in 1956 I bought a Gotham V80 when we first moved to New Mexico--no trees there like I had in Oregon! All the V80 consisted of was a long piece of aluminum and a loading coil! I don't remember how tall it was, but it may well have been something like 22 feet. It was base loaded, and not all that easy to use multi-band, particularly if you had it on the roof! It wasn't hard to make the decision to use it as a monoband vertical, and mine became a 20 meter vertical. I don't remember for sure, but I think the coil became superfluous! If I'd been smarter, I would have set it up like Jim Duffey suggested, although I don't remember anyone selling remote tuners back then.

Re: [Elecraft] OT Wet 450 ohm ladder line
Indeed I did. However, a few more words. The experiments that I ran were by necessity somewhat contrived and weren't very repeatable. What I was attempting to show was that there can be a detrimental effect when these lines become moist. Roy Lewallen, W7EL, has also written about this. The paper was a result of my reading The Lure of the Ladder Line (ref 1 in the paper) and saying to myself, Self, this looks too good to be true. When something looks this way, it usually is. Something mentioned, but discussed at much greater length in correspondence with Dean Straw, was the total lack of concern about balun and tuner losses at that time. I showed him by example that the ever popular tee-network used in many tuners that has three adjustable elements can be misadjusted so that it provides a match to the source but has extraordinarily high insertion loss. There are in effect an infinite number of wrong combinations and one that is correct. It wasn't long after this correspondence that articles by Frank Witt appeared on evaluating antenna tuners and today it is almost routine to see mention of tuner losses and possible misadjustment in papers on the subject. Whether this is coincidental or not is left to the reader. But when I see threads about, for example 43-foot verticals being matched on 160-meters with a built-in tuner or a little automatic box at the base of the antenna, or recommendations to use ladder line to feed ground-mounted verticals I really have to bite my tongue.

Re: [Elecraft] Tuning Pulser with K2
Don: It is a sensible question. A string of dots sent at nominal weight typically has a duty cycle of 50% off and 50% on. This is the weight to which I keep my keyer adjusted, and after sending that way for 45 years, I'm used to it. Typical SSB and CW sent as real characters have a duty cycle closer to 33% on and 67% off. The idea of the tuning pulser is to adjust the amplifier using a duty cycle similar to what it will encounter in normal operation. Now it is true that I could tune the amplifier by temporarily readjusting the keyer weighting for a 33% duty cycle, ramping up the speed to about 40 wpm, keying the radio (which requires actually keeping a hand on the key) and tuning. Then to revert to normal sending, I reset the keyer to my normal 20-25 wpm, reset the weight to normal weighting, and then have at it with my newly retuned amplifier. Note however that I have added about four steps to the tuning and I am in the extremely awkward position of trying to keep the string of dots going with one hand on the key and twiddling the knobs on the amplifier with the other. To make matters worse, I use a WinKey and the N1MM logger; the N1MM logger preempts the manual controls on the keyer. That means that in order to reset the weight of the keyer, I need to go to the N1MM's not especially friendly parameters menu twice, once top set up the pulser sequence, and then again to restore normal keying. As you can see, the above is possible in principle, but extremely awkward in practice. In contrast, if I connect the keyer and the tuning pulser (which is hard wired for a 33% duty cycle) to the K2 via a DPDT switch (one pole selects keyer vs pulser, the other controls the power to the pulser), I get my tuning pulses with a single flip of the switch. In addition, both hands are free to twiddle the amplifier, which means I get the tuning done non-trivially faster. Finally, to get back to normal sending, I just flip the switch back the other way. Unlike the Ameritron pulser which costs about $80 and has a lot of features that are totally unnecessary, this little pulser costs about $25 for the parts, and a lot less if you have a decently endowed junk box. This seems a small price to pay to greatly streamline the tuning process. 73, Steve AA4AK Don Wilhelm wrote: Steve, If you recall, it takes about 3 dot intervals (at 20 to 25 wpm) for the K2 to come up to the requested power after a band change, so what you are seeing is the result of your short pulses with longer intervals in between.

Re: [Elecraft] OT Wet 450 ohm ladder line
Open wire line changes a bit in wet weather due to moisture on the insulation between the wires. The worst is the type with a continuous web of insulation that was commonly used for television lead-in before coax came into common use. Next best is window line what is the same basic insulation, but wider spacing (and a higher impedance) with openings - windows - cut in the insulation to make it more like air dielectric line. The best is true open wire line which seems to be what you are referring to. With good insulators, it is virtually unaffected by moisture unless you dunk it in salt water. I've used both the commercial type with (polystyrene?) insulators and home brew stuff I made up using ceramic insulators. At my last QTH I had an inverted V doublet fed with open wire line. The center support was a wooden pole, so I made up the feed line using common dog bone end insulators. The insulators were mounted on the support pole using screw-eye standoffs. I got a bunch of the cheap screw eyes with the little insulator in the center made for use with TV twinlead and popped the little insulator out. The eye is soft metal that is easily bent, so I opened it up to slip it around the center of each 'dog bone' insulator then clamped it down with pliers. Ribs on the insulator kept the eye centered. Screwed them into the pole at about 3 foot intervals and then strung some #14 copper wire through the ends to make up the feeder. Kept the wire under a little tension with a few small ty-wraps to secure it. A bit of wire wrapped around the main conductor and running outside the hole would so as well. With a white pole, white dog bone insulators and using white insulated wire, the whole installation was very tidy and the feeder virtually invisible. I never noticed any significant change in tuning requirements (used an external manual tuner) on any band when it was dry, in the middle of a typical Oregon gully-washer downpour or when it was coated in ice. Ron AC7AC -Original Message- Sorry for an off-topic question. Does anyone have any information about the dry vs wet characteristics of 450 ohm ladder line? I have never used this type of line, but I might have to use it for mechanical reasons to feed another antenna now being built.

A remote ATU to compensate is not to be used with this particular antenna / feeder.

Re: [Elecraft] Wet 450 ohm ladder line
Yes, I've been using 450 line for years. I've switched back and forth from this to coax many times. The very best all purpose antenna that I've ever had is the one I now use. A 135' long doublet, up 45 feet, center fed with 75' of 450 ladder. That is terminated to a k-watt quality 1:1 balun, and then to an SGC-237 auto-tuner. From there, 40' of coax to the rig. This setup gives me operation on 160 and up with an average 1:8 SWR. On hot sunny day, snow blizzard or rain down-poor. Yes, the ladder Z characteristics do change with a heavy rain. But the auto-tuner compensates instantly. The advantage to this setup is the coax is always being used for what it is designed forunbalanced 50 ohms. And so RF loss due to mis-match is minimized. I am one very happy camper with this config! I think its true, a multi-band antenna is a compromised antenna. And I think the multi-band wire antenna is where ladder-line shines.

Re: [Elecraft] Tuning Pulser with K2
Gary: No need to run for the cellar. Your question merits an answer. Although you may find it hard to credit, I am primarily a QRP guy. The main reason I need to be able to run in excess of 100 Watts is when I do short haul (i.e., within my State of Maine) emergency and public service communications on 80 meters. About 25% of the time, the propagation conditions are not especially favorable for short haul communications and it takes about 400 Watts to assure reasonably reliable statewide coverage on 80 M. Ironically, at these same unfavorable times for short haul, I can easily be heard in Europe with 100 Watts, or even QRP, on 80 meters. Why go for an old tube type amp? I already own one; I bought it before solid state high power amps were available to hams. A fancy new solid state amp conveniently requires no tuning, but does require an investment in the $1200-2000 range (if not more) that I can ill afford (or so the XYL says, and her word is law in these matters) in these difficult financial times. 73, Steve AA4AK rfenab...@gmail.com wrote: Sure glad I don't own an old amp that needs tuning...:-) 100W, K3...what more does anyone NEED?

Re: [Elecraft] Elecraft Sales service
Until recently we were unable to ship more expensive items like K3s via U.S. Postal Service (USPS) to many countries because the USPS (or the local postal service in the destination country) would NOT insure above $500. This is still the case in Germany and a few other countries due to restrictions on that end. Fortunately we have recently found a way to use a combination of USPS insurance and insurance from an on-line shipping company that works with the USPS (Endicia) to insure K3s shipped via USPS at the full amount to most Eu and other countries (outside of Germany). For Germany UPS is still most common shipping method. The reason UPS appears more expensive than USPS in some cases is because UPS does not offer the slower USPS style shipment methods for packages to Europe. All of the UPS shipment options are 'express'. Those prices are close to the USPS express prices. We also have found that the end to end tracking on UPS is much better than USPS. We are always looking for alternate methods of shipping around the world. Feel free to email sa...@elecraft.com directly with any suggestions.

Re: [Elecraft] Tuning Pulser with K2
Steve, Not to belabor the point, but if simply tuning the amplifier is the goal, a 50% duty cycle should get the job done. Assuming the amplifier is supposed to be linear, tuning it at low power should get the settings close to the correct point and then a very short tuning time would be needed at full power. As long as the amplifier has a little bit of reserve (you are not pushing it to its max), a 33% duty cycle should not be necessary - I just can't understand why the amp's tuning points would change with the duty cycle. If you intend to tune the amp for a lengthy time at full rated power, then yes, it will be stressed at a 50% duty cycle, but for a reasonably short tuning period, I just don't see the need. I would just push a book against the dot paddle and tune away, move the book when done - no extra steps. 73, Don W3FPR Stephen W. Kercel wrote: Don: It is a sensible question.

Note however that I have added about four steps to the tuning and I am in the extremely awkward position of trying to keep the string of dots going with one hand on the key and twiddling the knobs on the amplifier with the other. To make matters worse, I use a WinKey and the N1MM logger; the N1MM logger preempts the manual controls on the keyer. That means that in order to reset the weight of the keyer, I need to go to the N1MM's not especially friendly parameters menu twice, once top set up the pulser sequence, and then again to restore normal keying. As you can see, the above is possible in principle, but extremely awkward in practice. In contrast, if I connect the keyer and the tuning pulser (which is hard wired for a 33% duty cycle) to the K2 via a DPDT switch (one pole selects keyer vs pulser, the other controls the power to the pulser), I get my tuning pulses with a single flip of the switch. In addition, both hands are free to twiddle the amplifier, which means I get the tuning done non-trivially faster. Finally, to get back to normal sending, I just flip the switch back the other way. Unlike the Ameritron pulser which costs about $80 and has a lot of features that are totally unnecessary, this little pulser costs about $25 for the parts, and a lot less if you have a decently endowed junk box. This seems a small price to pay to greatly streamline the tuning process. 73, Steve AA4AK __ 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] Elecraft Sales service
Eric Swartz - WA6HHQ, Elecraft wrote: Until recently we were unable to ship more expensive items like K3s via U.S. Postal Service (USPS) to many countries because the USPS (or the local postal service in the destination country) would NOT insure above $500. This is still the case in Germany and a few other countries due to restrictions on that end. Fortunately we have recently found a way to use a combination of USPS insurance and insurance from an on-line shipping company that works with the USPS (Endicia) to insure K3s shipped via USPS at the full amount to most Eu and other countries (outside of Germany). For Germany UPS is still most common shipping method. The reason UPS appears more expensive than USPS in some cases is because UPS does not offer the slower USPS style shipment methods for packages to Europe. All of the UPS shipment options are 'express'. Those prices are close to the USPS express prices. We also have found that the end to end tracking on UPS is much better than USPS. We are always looking for alternate methods of shipping around the world. Feel free to email sa...@elecraft.com directly with any suggestions. Also, Katie, Lisa and Madelyn are very friendly and knowledgeable in this area. They work extremely hard to ship via the best possible method to each customer. Feel free to correspond with them if you have any questions on your shipping method. Eric, if Hendricks QRP Kits can ship a Bitx20 kit with metal case to any DX location for 15% of the cost of the item (which is $165, therefore about $25 for shipping, and it is presumably bigger and heavier than a K3 add-in module) why did a KRX3 plus a couple of mod kits requite USPS International Priority Mail at a cost of $42? Are they taking a loss on the shipping, or are they using a method you haven't discovered? I would just like to add that the sales team are indeed very nice and Lisa has just replied to my apology for my abruptness saying she understood my frustration and would be pretty annoyed if she had thought a company she ordered something from had mis-addressed it.

[Elecraft] A software lock preventing reverse mode?
Hi, When I use Logic 8 there is a nice feature where there is a DX Spot log. This reflects on the air spots and evaluates my database to let me know what is posted that I need on which band for which award. When I click on a call, the K3 automatically goes to what band and mode was posted and even moves the transmit/SPLIT to the DX's listening freq if posted. Almost perfect except for some reason, when engaging this, the command also moves the K3 to listen in the reverse position. I've learned to click on the spot in logic and then press the ALT on the K3 to put the signal to normal but I'd like to be able to have the ability in the config menu to tell the K3 to ignore the REV comand unless physically selected by the ALT button or just to ignore it totally unless I intentionally enable it again.

Re: [Elecraft] K3 and N1MM Logger Configuration Rosetta Stone
Greg, I noticed the same problem sending CW to the K3 using my own software, CQPWIN, and a Winkeyer when using the Winkeyer to assert PTT. The cure was adding even a small amount of Winkey keying delay (as little as 10 msec did the trick). So if N1MM allows you to do that, you might investigate it. Also, using the Winkeyer does allow one to avoid having another line for PTT. And with modern laptops there is an advantage that you can use it directly attached to a USB port without any serial port converters needed (the Winkey software generates a virtual serial port that the computer uses). 73, Andy, ae6y - Original Message - From: Jim Brown j...@audiosystemsgroup.com To: Elecraft List elecraft@mailman.qth.net Sent: Tuesday, March 17, 2009 11:36 AM Subject: Re: [Elecraft] K3 and N1MM Logger Configuration Rosetta Stone On Tue, 17 Mar 2009 09:55:22 -0400, Greg - AB7R wrote: Hi Jim.

[Elecraft] New to HAM and the K1
Hello, I am new the to HAM hobby and just finished building my first K1. All has went well for the most part, but I am having trouble understanding the alignment process. I have searched the email list and older postings to try and find some help but still a little fuzzy. First off, I am currently a contractor overseas and do not have access to a lot of equipment or parts. I usually have to order stuff in even the simple stuff like solder. So anyway I purchased the signal generator kit from elecraft to use for a signal source for alignment and I am having trouble knowing whether it is even working or not. Its supposed to be 7.040 MHz but I go to that freq and can't find it. So I thought about using the Spectrogram software, but not sure how to connect that to the K1, since there is no RS232 connection. Any help would be appreciated. 73, KD0FJM __ 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] A software lock preventing reverse mode?
I've been using Logic since the early 90s. Dennis only fixes what he wants to fix. I suppose if he had a K3 to work with or knew the involved command structure, he might find the issue simple to resolve. He's using the Kenwood interface for the K3 and I believe he feels the K2 is essentially the same command set as the K3. If this going to REV happens with Logic it as easily could be caused by another program deciding to do the same or similar function. If a config lock were available, it would resolve the problem. It would also prevent accidental going into reverse when accidentally depressing ALT (not that that happens often but I have done it before). IMO this should be handled by Logic8 and not compensated for in the K3. I've had problems when clicking on spots from Logic where it would not always set the correct mode. I've emailed Dennis about this and he made a brief attempt to fix this. When his attempt didn't work he gave up on it.

[Elecraft] [K3] Noise Blanker Observations?
All - One of the reasons for purchasing a K3 over, say, an Icom IC-756ProIII was that the ProII I used to have had a noise blanker button, but it never seemed to actually do much. Sadly, I'm in the midst of several severe power line noise sources (the power company is getting to them as they can), but I'm finding that my K3 NB is having no effect, in ANY of the zillion settings available. This isn't strange, bizarro noise - just arching from a power line. Is anyone else experiencing less than satisfactory NB performance with their K3? I'm running the latest Production firmware. Comments appreciated - you can make them private, if you like, and I'll post a summary.

Re: [Elecraft] New to HAM and the K1
Jim, You do not need anything more than a stereo cable with a 1/8 inch stereo plug on each end to use Spectrogram. In fact the cable does not have to be stereo, just the plugs (connect only the tip and sleeve if you are building the cable). The cable connects between the K1 headphone output and the computer soundcard LINE-IN. If you can receive a signal at all, the Spectrogram display will help you tune the filters for a peak in the signal amplitude. You really don't even need Spectrogram, you can use your ears. Spectrogram just makes it much easier to see the relative amplitude and the audio frequency of a received signal. First off, when aligning the K1, it is good to have a strong signal generator for each of the bands you have on your K1 - sometimes it is not necessary, but if you cannot hear any signals, it is a good bet that the Pre-Mixer bandpass filter and the RF Bandpass filter on the 2 band or 4 band board need better alignment - and to initially align them it is nice to have a strong signal within the tuning range of each K1 band. Another QRP transmitter nearby working into a dummy load is often a good source of such a strong signal. The XG1 or XG2 output is only at an S-9 level, and often is not strong enough for the initial alignment. If you have no strong signal source, tune around to see if you can hear any signal at all, if so, use that to do the initial receive alignment. If you have the 4 band filter board, the trimmers should all be near the center of their tuning range (the screwdriver slots should be aligned parallel with the long edge of the 4 band board to start with, and the final tuning will not be far away from that position unless you have a problem with the toroids). Once you have the pre-mixer bandpass and RF bandpass filters set so you can receive signals, the alignment of these filters is refined by using transmit mode - connect a dummy load and read the power output from the K1 display, no other equipment is needed, just tune for peak power output - if the power rises substantially, you will have to exit TUNE and enter TUNE again to bring the power back down to the value in the OUT menu parameter. After you have the pre-mixer and RF bandpass filters aligned, go back to Spectrogram, and use a noise source on the antenna input - connect an antenna and tune to a spot with no signals in the passband if you do not have a wideband noise generator. Now switch to FL3 and note the audio frequency of the passband center on the Spectrogram display. If it is not at your chosen sidetone pitch, adjust the recieve BFO trimmer (C20) so the passband is centered at your sidetone pitch. Then, with Spectrogram still displaying, move the switch on the bottom of the RF board to the TEST position and adjust the transmit BFO trimmer (C13) to place the large signal that you see on the Spectrogram display at your chosen sidetone pitch. Place the switch back in the OP position and you will have the BFOs aligned. If you have the KNB1 installed, tune in a signal and using Spectrogram as the display aid, adjust the trimmer on that board for a maximum amplitude received signal. The rest of the alignment and calibration is done by adjusting the menu parameters (CAL OPF, SIG, etc.). 73, Don W3FPR Jim Cannan wrote: Hello, I am new the to HAM hobby and just finished building my first K1. All has went well for the most part, but I am having trouble understanding the alignment process. I have searched the email list and older postings to try and find some help but still a little fuzzy. First off, I am currently a contractor overseas and do not have access to a lot of equipment or parts. I usually have to order stuff in even the simple stuff like solder. So anyway I purchased the signal generator kit from elecraft to use for a signal source for alignment and I am having trouble knowing whether it is even working or not. Its supposed to be 7.040 MHz but I go to that freq and can't find it. So I thought about using the Spectrogram software, but not sure how to connect that to the K1, since there is no RS232 connection.

Please reread my message.

[Elecraft] New Beta
Just loaded MCU 3.03 and DSP1 2.. 2.10. Went without a hitch. 73 de KE4WY Jim __ 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] K3 Firmware rev. 3.03: SUB RX band independence, new AGC features, multiple ATU settings per band, etc.
K3 beta-test firmware revision 3.03 (with DSP rev 2.10) is now available. This is a major firmware release, with a number of new features: - Band independence for the sub receiver (CONFIG:VFO IND) - New AGC features, especially for use in pileups (CONFIG:AGC DCY, AGC HLD) - Fast-tuning spurious receive signal removal (CONFIG:SIG RMV) - Multiple ATU settings per band; per-band/per-antenna auto/bypass selection - Improved behavior of PTT and the TX LED - Extended transverter frequency coverage when used with a 10-m I.F. For details, see the release notes below. Please send any problem reports to k3supp...@elecraft.com. For instructions on how to load beta firmware, please see: http://www.elecraft.com/K3/k3_software.htm We also recommend that you use the latest revision of K3 Utility, which can also be found on the K3 software page. 73, Wayne N6KR * * * MCU 3.03/DSP 2.10, 3-17-2009 New Feature: Band Independence for the Sub Receiver * MAIN/SUB RECEIVER BAND INDEPENDENCE. If CONFIG:VFO IND is set to YES, then VFO A and B can be set to different bands. In this case BAND UP/BAND DN will only move VFO A, but in BSET mode, they will apply to VFO B. VFO B can also have a different mode from VFO A. Some RX parameters can be set differently for the sub receiver when in BSET mode, including PRE, ATTN, all DSP controls, and NB (noise blanker) settings. Limitations: For now, NR, notch, and some other controls remain common to both receivers. Internal text decode (CW, FSK-D, PSK-D) is available only for the main receiver. Scanning still must be set up using both VFO A and B on the same band. Memory recall only updates VFO A if VFO B is on a different band. (Most restrictions will be removed in future revisions.) New AGC Features Introduction: All AGC systems modulate in-band signals to some degree, creating IMD if multiple signals are present. But you now have several choices when conditions are difficult: (1) AGC OFF, which eliminates virtually all in-band IMD, but requires “riding” of the RF GAIN control. (2) Slow AGC (AGC-S) with a nonzero hold time, typically 0.2 seconds or more (see CONFIG:AGC HLD below). This is nearly as clean as AGC OFF, but the AGC will charge on strong signals, reducing gain for the duration of the AGC HLD amount. This can be distracting. (3) Soft-decay AGC (see CONFIG:AGC DCY, below, which applies to AGC-S/-F). This recovers much faster than AGC-S with a long hold applied, and produces only a little more IMD. In the case of AGC-F (fast), soft decay will result in slower recovery time between code elements than normal decay (nor), but it will still be much faster than AGC-S with a hold time applied. (4) Normal-decay AGC. This is the traditional DSP-based AGC decay characteristic, and it will create a lot more IMD than the other alternatives. (An application note showing the effect on actual signals is pending.) * AGC DCY MENU ENTRY (AGC decay type): Allows you to select Soft or normal AGC decay characteristic. When AGC DCY is set to “Soft,” both slow and fast AGC will create less in-band IMD (intermodulation distortion) in multi-signal situations (e.g., pileups). You can assign AGC DCY to a programmable function switch (PF1/2 hold, or M1-4 tap or hold) if you need to turn it on/off quickly. * AGC HLD MENU ENTRY (slow AGC hold time): AGC HLD now applies to CW mode (originally it applied only to voice/data). AGC HLD may reduce receive IMD caused by normal AGC-S/AGC-F decay times. Settings of about 0.3-1.0 seconds should improve copy when many closely spaced signals are present, as in a CW pileup. No effect on AGC-F. New ATU (KAT3) Features * MULTIPLE KAT3 ATU DATA SEGMENTS PER BAND/PER-ANT.: 10 kHz per segment on 160 m; 20 kHz on 80-12 m; 50 kHz on 10 m; 200 kHz on 6 m. This keeps narrowband antennas in tune across the full ham band. Note 1: You *do not* need to go through each band and do ATU TUNE on every segment. The K3 will use the saved LC data segment closest to your present VFO location, gradually learning what settings to use everytime you do an ATU TUNE. Note 2: You can erase all of the stored LC data for a given band by tapping CLR in the CONFIG:KAT3 menu entry. * AUTOMATIC KAT3 LC NETWORK UPDATE ON TRANSMIT: Each time you transmit, the K3 first determines whether you’ve moved the VFO closer to another stored ATU data segment. If so, it will re-load the KAT3 with this data, and flash the “ATU” icon twice, briefly. You’ll hear one or more relays on the KAT3 change state. This will not interrupt transmit. * ATU MODE STORED PER-BAND, PER-ANTENNA: You can now set up the KAT3’s mode (AUTO, BYPASS, etc.) on a per-band/per-antenna (1/2) basis. This is very useful if you have well-matched antennas on some bands, or a dummy load connected to one of the ANT jacks. New Feature: Spurious Signal Removal * SPURIOUS SIGNAL REMOVAL: Fast-tuning “birdies” can in some cases be eliminated using the new “Signal Removal” feature (CONFIG:SIG RMV). We

[Elecraft] Assembling a K3
Hello all: I'm new to the list and the world of Elecraft. Just picked up my K3 from UPS yesterday. Last night, I managed to unpack the kit, sort the hardware and inventory the other items. Looks like everything arrived. Assembly should begin tonight. I have read the tips in the assembly manual. So, I have the static mat and wrist strap. But, I wondered if there would be a problem using magnetic tools. Is this something that should be avoided? Thanks much and 73, Jed AD7KG __ 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] Assembling a K3
Jed, magnetic tools and ferrite cores can be a problem. I've had radios in for repair in the past where someone has carried the radio with a magnetic mount antenna on top of the radio... It was seriously down in performance and only restored to normal operation with new cores. I am not sure what magnetic tools you might use, but ordinary (and good tip) screwdrivers, narrow nose pliers and a pair of stainless tweezers were fine for my K3 assembly 16 months ago. Don't forget to load the latest release of beta firmware as mentioned elsewhere on here, it's a big improvement and well worth installing. 73 Dave, G4AON K3/100 #80 (from Nov 2007) -- I have read the tips in the assembly manual.

[Elecraft] KX1 Spring Tune Up
Its spring and I am getting ready for some backpacking with my KX1 so I thought I would take the time to tweak/tune/analyze/hot rod my baby. The rig is fully loaded. 4 bands, ATU and the SMD CW TUNING AID. I have several projects on the agenda. 1. Scope analysis 2. Dummy load construction with DVM RF measurement capabilities. Or just buy the Elecraft dummy load! 3. Possible tweaking of the existing hardware. 4. Exploring the possibility of increasing the power output to a full 5 watts. Just for the record, the KX1 is working FB on all bands and the readings on the rig are all within specs! Well, one thing at a time. I have hooked up my scope a dummy load consisting of six, 5 watt Milwaukee 300 ohm sand resistors in parallel. These resistors were given to attendees at hands on session of my local radio club. I was dubious about the resistor choice as I understand that these are wire wound and that is not appropriate for a dummy load. Sure enough, when comparing the SWR of the homemade dummy load, my MFJ-9895 and a BNC ½ watt 50 ohm terminator I found that the homemade load showed different SWR readings at 80, 40, 30 and 20 meters. While the MFJ and BNC terminator showed 1.0 SWR on the rig. The MFJ also showed the 1.0 on all four bands its SWR meter. Well, for convenience sake made I made my first scope connection on the homemade dummy load at 3.550 MHz. BATTERY NO LOAD = 12 VDC ON DVM.

The self calibration function shows the same measurements as when I bought it. So, I have two questions for the group at this point! 1. Are my measurements consistent with what a KX1 would be likely to put out? 2. Am I correct in thinking that the resistors in the homemade load are not the best choice? For what it is worth, I have found several articles on the web re: dummy loads and also looked at the schematic for the Elecraft dummy load and all indications are that sand style, rectangular, wire round resistors are not appropriate! It is true that my measurements confirm this, but as my construction technique was rushed, I do not want to assume anything! If my measurements pass the smell test I am going to trace the RF path of the KX1 end to end in order to establish a baseline! At that point, I will decide whether to try tweaking the KX1 or to continue home brewing a dummy load with power metering capabilities like the Elecraft dummy load!

Re: [Elecraft] New Beta
Bruce, The short answer is yes. Now, having said that, there are some alignment procedures you have to do once it is assembled. They are fairly minimal, but they have to be done. Once I had mine together, it took me another hour of fiddling with the rig - reading the book and understanding what they were talking about - to get it on the air. No trouble since. I've gone through many up dates and just updated a few minutes ago to the latest firmware. I am not sure what you mean by environment, but I am sure you would have the latest firmware release other than the beta releases. I am not sure where they in the official release, but the rig would work. They do ship with with a working release, it might not be the latest gee-whiz release, but it will work FB, It has been a grand time with my K3 which I have had for a year now. 73 Lee K0WA The New Kansas QSO Party - August 29, Sat 9am-9pm and August 30 Sun 9am-3pm CDT In our day and age it seems that Common Sense is in short supply.

Re: [Elecraft] Tuning Pulser with K2
Don: Certainly, for A CW guy like me, sliding a book against the dot paddle would probably work. However, flipping a toggle switch to get a pulse stream is much more convenient, especially when the electronics attached to the toggle switch cost only a few dollars. (Side note: The tuning pulser is one of the few instances where I have found that home brew is substantially cheaper than getting store bought.) The idea that the tuning point is affected by the duty cycle is claimed on several different a RF amplifier Web sites. Perhaps they are mistaken. I must admit that I wonder why a genuinely linear system would have its tuning point affected by the duty cycle. Anyway, your suggested fix turned out to be correct. After some searching through my junk collection, I did find a capacitor of the proper value, and increased the pulse duration from 12 to 24 ms while preserving a 33% duty cycle. That completely resolved the one bar less effect. I do find that it takes more than 3 dots for the transmitter to come up to full power when I change bands and then run the pulser. The higher the frequency band, the longer the delay, taking only a few dots to come to full power on 80 meters but several seconds to come up to full power on 10 meters. 73, Steve AA4AK Don Wilhelm wrote: Steve, Not to belabor the point, but if simply tuning the amplifier is the goal, a 50% duty cycle should get the job done. Assuming the amplifier is supposed to be linear, tuning it at low power should get the settings close to the correct point and then a very short tuning time would be needed at full power. As long as the amplifier has a little bit of reserve (you are not pushing it to its max), a 33% duty cycle should not be necessary - I just can't understand why the amp's tuning points would change with the duty cycle. If you intend to tune the amp for a lengthy time at full rated power, then yes, it will be stressed at a 50% duty cycle, but for a reasonably short tuning period, I just don't see the need. I would just push a book against the dot paddle and tune away, move the book when done - no extra steps. 73, Don W3FPR __ 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] KX1 Spring Tune Up
Jack, Several comments. First, I would *not* recommend that you run the KX1 power up to 5 watts - keep it at 4 watts max. The zener in the PA output may break down if you connect to a high SWR load, as may the capacitors in the Low Pass Filter - they are only rated at 50 volts, and a high SWR load may cause that rating to be exceeded. Better to keep the power down than to have the KX1 break on you just when you want to use it most. 4 watts with a 13.8 volt power source is about what I expect of a KX1 with the KXB3080 option, and that will be only on 80 and 30 meters. 40 and 20 will be lower, but I expect at least 3.3 watts on 20 with that 13.8 volt supply. The power output with lower DC voltages will be lower. Your 2.56 watts is a small bit on the low side with a 12 volt supply. Secondly, check any dummy load with an antenna analyzer at the frequency of interest so you know what you are dealing with - if it is good, it will have only a resistive component and zero reactance - anything other than that renders it of lesser value for valid measurements. If you want a good dummy load that is light in weight, mount a 50 ohm Caddock thick film power resistor on a heat sink salvaged from a defunct computer CPU cooler. The 15 watt unit is Mouser 684-MP915-50 - it is a 1% resistor, and the 50 ohm resistors are good for RF usage (other values may be capacitive). When mounted with only its leads to a BNC connector, it will be flat up through 222 MHz or more. Your 'scope measurement of the Peak to Peak RF voltage is good as long as you are using a 10X probe on the 'scope - connect the probe to your 'scope's calibrator and make certain the probe is properly compensated. If you want a quicker way to calculate the power, square the peak to peak voltage and divide by 400, and you will have the power directly without going through conversions. The derivation of that formula is an exercise for the student, but I have posted the derivation on this reflector before. One easy to remember data point is that 40 volts peak to peak is equal to 4 watts. 73, Don W3FPR Jack Regan wrote: Its’ spring and I am getting ready for some backpacking with my KX1 so I thought I would take the time to tweak/tune/analyze/hot rod my baby.
