[Elecraft] Operator skills training
This morning, after an enjoyable hour chatting with my mentor on 20 meters, I came to a realization about the skills learned via contesting and acting as net control. Thursday night I had a fun catching both foxes in the summer fox hunt while on field day I had a good time work stations far and wide. ECN has me digging for signals trying my best to get everyone who is trying to check in. After I got off the air I was out hiking around the mountain thinking about the contact. There was QSB at the same rate as the CW combined with a slow fade which caused letters to simply disappear. But we made it work. If not for all those skills learned from other ragchews, a bit of contesting, and ECN I may have thrown in the towel early and said I simply cannot copy you. But, I could copy him; the skills were there due to the time spent digging during contests and nets. My walk was fun but the realization I had gained enough skills to have an hour long chat under less than ideal conditions because I had contested and acted as net control made my step a bit lighter and the day feel much better. The aches and pains of working at a computer for many hours drained away as I thought about the contact. Amateur radio is a diverse hobby; I find each facet I explore assists me in becoming a better operator. I have the most fun meeting new people and simply chatting away on CW for an hour or so. Keeps me sane :) 73, Kevin. KD5ONS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] KAT100: No SWR Indication
After working OK for several years, my KAT100 no longer indicates SWR, nor does it tune properly. When used with my K2/100, in ATU Auto mode, with the TUNE button, the KAT100 starts finding a match as expected. However, none of the SWR LEDs illuminate, and the K2 display indicates 1.0-1 SWR during the entire search. I am not at all convinced that it has found a good match once the tuning sequence completes. An SWR bridge placed between the K2 and the KAT often shows a poor match after tuning. I suspect a problem in the KAT's SWR bridge, but does anyone have specific troubleshooting advice?

Re: [Elecraft] Re: K3 RX performance (tantalizing preview)
On May 14, 2007, at 11:48 AM, Scott Manthe wrote: One reason is called the inverse square law. I'm familiar with that. There's a HUGE difference in a rig being able to deal with a kilowatt signal a couple blocks away and being able to deal with a kilowatt signal in the same room. I'm aware of that, too. However, I wasn't talking about a kW a couple of blocks away. I was talking about 100 watts in the same box, or 1.5 kW inside a 100m circle (tops!). At a M/M station with more than 6 rigs, you'll have two radios on the SAME band, using antennas that are just a few dozen meters from each other. Another is that almost everyone who doesn't want to destroy their rig's front-end uses giant bandpass filters in front of each rig in a SO2R setup. First, this isn't true. You don't need huge bandpass filters for an SO2R setup. A typical 1.5 kW SO2R station will use a set of receive filters or stubs to reject out-of-band signals. For 100w SO2R, you don't need to have the filters. Second, in the M/M comparison, you have two rigs on the SAME band, so bandpass filters don't do you any good. At NQ4I's M/M many of the second rigs don't use a bandpass filter at all (although he has them available -- I know, I built one set for him). They won't help with the in-band signals from the primary rig, although they are useful for getting rid of mixing products from the other five transmitting stations on the other bands Including eleven of these filters to cover all the bands the K3 will cover would make it the size of a broadcast transmitter. You don't need it. For reference for the HF challenged, take a look at a good set of repeater duplexers. Now, multiply that by eleven bands. You don't need filters the size of repeater duplexers to do this. It's one thing for a 2 meter/440 rig to be able to transmit and RX at the same time- they're running maybe 50 watts at 300 mHz spacing. It's not so easy with a rig running 100 watts, a kilowatt, or at some stations, several kilowatts at 2 or 3 mHz spacing. At NQ4I, with antenna separation of just a few dozen meters, we can often receive effectively within 10 kHz of the primary station. -- Let's put it this way -- many SO2R stations use the Top-Ten A/B switches to separate their antennas for two rigs: http://www.qth.com/ topten/abss.htm These switches only offer 80 dB of isolation. The Array Solutions SixPac has similar specifications: http:// www.arraysolutions.com/Products/sixpak.htm About 80 dB of isolation below 30 MHz. The web page indicates you should worry more about the coupling between antennas than the isolation of the switch. So, if 80 dB of isolation is sufficient for 1.5 kW signals, then 100 W signals would need 12 dB less, or only 68 dB to achieve the same level of received signal in the second receiver. Call it only 70 dB. That seems achievable. I don't understand why that couldn't be achieved in a box the size of the K3.

Re: [Elecraft] K3 RS323 and Data Modes {was YAQ - Yet Another (K3)Question}
On Jul 9, 2007, at 4:44 PM, Brian Lloyd wrote: Well, you have just described the product offerings from Flex Radio. Not exactly what I had in mind -- there's way too much hardware involved. My concern over the Flex Radio SDR approach compared to Elecraft's approach in the K3 is that, in order to be able to receive multiple signals simultaneously, e.g. like we do in demodulating PK31, you have to accept all the noise and cruft in the wider passband. If there is a strong signal in there you have to pass it through to the A:D and hope that the A:D has sufficient dynamic range to deal with the difference between the desired signal and the undesired signal. No. You don't "hope" the A/D has enough dynamic range. You have to design in that kind of dynamic range. Which means you've got to use an A/D converter which has lots of bits -- very expensive today. Elecraft gets rid of the undesired signal by using tight roofing filters. Yup, that's one approach. It also is very cost-effective for a single- signal type receiver. It's still possible to get good IMD characteristics with an up- conversion general-coverage receiver. There are some $10,000 radios on the market that do exactly this. But all of them upconvert to something like a 70MHz 1st IF. You aren't going to find a 200Hz roofing filter there. That means you aren't going to get the good close-in (1KHz spacing) IMD and BDR performance. So to get general coverage receiver performance you give up close-in BDR and IMD performance. Again TANSTAAFL. Consider the Yaesu FT DX 9000. This design has a 40 MHz first IF that has roofing filters of 3, 6 and 15 kHz. Similarly, the Icom IC-7800. This design has a first IF of 64.455 MHz and roofing filters of 3, 6 and 15 kHz. Both of these designs have competitive IMD and BDR characteristics. It is possible to do this with wider roofing filters in an up- conversion design. However, it isn't as cost-effective as the Elecraft design. (I can buy several fully-loaded K3s for the price of one FT DX 9000 or IC-7800) I agree. Elecraft should be receiving the order from the ARRL for our school's K2. I plan to let the kids (4th-8th grades) build the rig under my guidance. I think that the K2 will perform a lot better than the other rigs that they were offering us, e.g. Icom IC-706, and I think that the kids will understand and appreciate the radio better if they have a hand in building, testing, and calibrating it. I totally agree. When I was first licensed, one of my dreams was to design and build a state of the art homebrew transceiver. For a number of reasons, I never quite did that, but with the Elecraft K2/100, I've come close.

This is a very interesting post. Several of us have asked if the enclosure the KAT100 and transverters come in is available as we had projects for them. To my knowledge they are not available like the EC2 enclosure. It makes it interesting for someone who built the KAT100 into an EC2 case right at the start to change back. I would like to know the answer to this one as well :-) Ian -- Ian J Maude G0VGS SysOp GB7MBC DX Cluster Member of RSGB, ARRL, GQRP K2 #4044 | K3 #? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 is still a good choice
Larry, You can't go wrong with a K2. I have built the K2, KPA/100, KAT2 tuner, and several add-on modules over the past year. Great results and it is an enjoyable, and compact rig. I also took my rig to a club meeting and it was enjoyed by the group, although there were a few others that were already familiar with Elecraft, and a couple who owned second-hand K2s. I agree that I would like to have seen a complete K3 kit (not a mechanical-assembly-only kit). Can't knock Elecraft for their decision (it IS their business), but if there was a full-assembly K3, I would probably be ordering one soon. My concern now is that they are so preoccupied with the K3 that we will not see significant upgrades to the K2 design any time soon. 73, Tom KG3V On 7/12/07, Larry <[EMAIL PROTECTED]> wrote: I just ordered a K2. I was * *seduce like many others when the K3 was announced but the one thing that really bothered me was that it was not a kit. Having built the K1 I really miss not having a board under my iron. I also realized that the K2 was far more radio then I have ever owned. I will buy an oscilloscope with the money that I save. This is a real win win. Speaking of the K1, I took it to the June club meeting here in Las Vegas for show and tell. It was the hit of the evening. There were about 25 or 30 people there and only a few of them had even heard of Elecraft. No one else had built a kit. I know that Elecraft will get at least 2 orders from that group. 73 Larry KB5DXY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Zero-Beating Made Easy!
Hello all, Don't worry about zero-beating to find the other ops frequency! Just add a K6XX CW Visual Indicator to your K1, K2 or KX1. All you do is tune onto a signal until the LED starts flashing to the cw. That's it - your within +- 20hz of him! The EPA QRP Club will begin selling the kits in a week or so. Nice small board that nicely fits into most rigs.

That's part of it. Another part is that power level measurement has changed from the old power-input measure to the "new" power output measure, so efficiency doesn't matter as much as it used to. > > > So, > > what has changed?

While > it is possible to build tube rigs with no tuneup controls (the CE 100V, 200V > and 600L did it in the 1950s!), it's arguably easier to do with SS. The big item, I think, is the cost and availability of the different designs. Not just the tubes but all the other parts, many of which would have to be custom made. The total price of a conventional tube amp and power supply, with tuning controls and QSK, really starts to climb when you're getting a lot of parts custom-made. That situation is complicated by the used-equipment market. If you want to run, say, a pair of 3-500Zs, and are willing to do your own tuning, a Drake L4 or Heath SB-220/221 can do the job. Even if you have to put fixup into one and retube it, such amps are pretty price-competitive to a new pair-of-3-500Zs amp. There's also the danger of creating an amp whose tubes become unobtanium. You can get a really good deal on the Heath SB-630 amp, because its conduction-cooled tube is very expensive to replace. Elecraft has built itself on the idea of offering products that are *not* exactly like everything else on the market, but rather go off in new and exciting directions. On FD I spent some time with a KX1 - the thing is simply incredible, but also, there's nothing on the market quite like it. The Elecraft amps show that trend as well. 73 de Jim, N2EY ** Get a sneak peak of the all-new AOL at http://discover.aol.com/memed/aolcom30tour ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
