Re: Re: [Elecraft] K3 CE
Don't forget that, aside from CE marking, you are deemed to be techniclly competent as an Advanced licence holder and can therefore build your own kit and operate it within the terms of your licence.

Toby makes a valid point as concerns resale, but being pragmatic, we don't live in a bureaucratic police state where officials go through the small ads checking on what people are selling, so whether it's legal or not, it's certainly going to be under the radar. I think the only issue that may concern Elecraft is if it is likely that imports are going to be stopped at customs and returned at their expense. If it's OK for goods to be certified at this end then it obviously isn't illegal to import uncertified goods therefore customs isn't going to be bothered. -- Julian, G4ILO K2 s/n: 392 K3 s/n: ???

[Elecraft] OT:QEX High performance homebrew transceiver design.
Hi Elecrafters There is a nice homebrew transceiver project in this months QEX. This article can also be downloaded from the QEX web page as it is the feature preview article. Whats so impressive about this design is the impressive size and the great performance numbers which any transceiver today would have trouble equaling. Many would be interested in the design philosophy and technical outcomes. Craig VK3HE Be a better pen pal. Text or chat with friends inside Yahoo! Mail.

Re: Re: [Elecraft] K3 CE
In the past the authorities were concerned with amateurs causing interference to domestic radio/television reception and all other government services. Now it is the amateur that has the problem. We now have to contend with radio interference to our hobby from:- TV's (LCD Plasma), Cable TV, PLT, HomePlug, Switch Mode PSU's either freestanding (wall warts) or in-built(Computer), electronic controls in anything from a central heating boiler to a sewing machine . et .al. It's a bit ironic that, as rigs such as the K3 are now being sold with a superb receive performance that many amateurs are unable to use due to increasing radio spectrum pollution. Many items sold into the domestic market would appear to be either non - compliant, or have a test standard applied that is most advantageous to their products. A lot of items are able to cause HF interference because, the only radiated emissions testing required is carried out above 30MHz. Below 30MHz only the conducted interference on the supply lead is tested. In the UK the enforcing agency is the Trading Standards. They are lacking in funding, manpower and technical knowledge to deal with anything other than life threatening issues (i.e. Lead paint on toys). As far as the EMC part of CE goes, it promised a lot, but has delivered very little Stewart G3RXQ Member RSGB EMC Committee On Thu, 15 Nov 2007 08:51:20 +, Julian G4ILO wrote: On Nov 15, 2007 8:24 AM, [EMAIL PROTECTED] wrote: Don't forget that, aside from CE marking, you are deemed to be techniclly competent as an Advanced licence holder and can therefore build your own kit and operate it within the terms of your licence.

Re: Re: [Elecraft] K3 CE
This is, unfortunately, so true. It is getting to the stage when I wonder how much longer it is possible for someone in my situation to operate a stealth station in a crowded urban housing estate. It is not the limited size of my antennas that is the problem but the interference I have to contend with. I can turn off my electrics and it makes little difference to the noise level, which is often S3-S5 on the K3's rather stingy S meter. As for the situation in Germany, well if that's the law and people will actually check up on it then you have to go along with it. But only a politician could bring about a situation where it is an offense to use equipment that doesn't have a worthless sticker on it. And CE certification is worthless unless it guarantees that the equipment meets a worthwhile standard. I think the only solution that would solve the interference problem would involve type approval of equipment by independent tester. Clearly you can't rely on all manufacturers to self-certify with any degree of honesty. And given the lack of enforcement in the UK there is no reason for anyone to do more than pay lip service to the regulations. No doubt you can buy rolls of self adhesive CE stickers from some Chinese vendor on eBay... But despite the benefits to us hams of type approval, I'm not sure I'd like the extra costs and restricted range of products such a measure would result in. I can remember just how expensive modems were in the 80s when they had to be type approved by the monopoly telecoms provider. -- Julian, G4ILO K2 s/n: 392 K3 s/n: ???

Therefore this whole CE marking busines seems to me to be a total waste of time, as it is either unenforced or unenforceable. Sorry, I don't agree. Overall, I think the European EMC regulations have been a success - so much so that we take them for granted. It's always the leakage around the system that gets the publicity, and it only takes one small thing like an unfiltered wall wart to cause problems for us. The vast majority of electronic and electrical appliances coming into European homes are 'mainstream' products from European companies, or from international companies with substantial business operations in Europe. Regardless of where they were actually manufactured, these products do comply with all the relevant product standards. European radio amateurs have definitely benefited from this. The RFI mailing list has frequent horror stories from the USA that just don't happen over here any more. As licensed amateurs we are personally responsible for EMC compliance, the only difference being that we don't have to provide formal demonstrations or documentation. For kits and ready-made amateur radio equipment imported from outside Europe, practical experience is that personal importers are never asked to demonstrate compliance. I can certainly confirm that as an exporter of kits and boards to the rest of Europe, the USA and around the world - in over a thousand transactions, never a single challenge. According to Wayne's posting a couple of weeks ago, Elecraft has already done the testing to demonstrate compliance with the relevant European standards - which the K3 passed easily, of course. As soon as all the necessary documentation has been assembled, they will immediately become legally entitled to attach a CE sticker (they don't have to file it with anyone else). But, quite rightly, that isn't Elecraft's main priority just now. For K3s being imported into Europe at present, that leaves only the most trivial technicality: a product that does in fact meet all the relevant European standards, but doesn't have a CE marking to say so. Worrying about such little things is a symptom of severe K3 deprivation! Fortunately, there is also a complete cure for this condition :-) As soon as the documentation does comes into existence, the owners of unmarked K3s will become legally entitled to attach a CE sticker themselves. They don't need any documentation to do this; it is sufficient to know that valid documents exist.

Re: [Elecraft] Need some help on a K1 problem.
Len, Are you certain it is a relay problem? Does your 4 band board work on 15/17 meters without manually setting any relays? If it is a relay problem, the reset state of the relays is with the 15 meter band selected and you should be able to align and operate it on that band. Can you turn the attenuator on and off with this 4 band board installed? If so, the IOC chip is working and the resonator is good. If you do have a relay problem, make continuity checks from the U1 pins to pin 8 of each relay (check the schematic to determine the corresponding pins of U1), and check continuity from P2 pin 3 to each of the relays Pin 1. When checking to the U1 pins, plug the firmware chip in and measure from the actual lead of the chip rather than the socket - that will reveal any socket problems. Check the resistance of each relay coil to see if you might have one with an open coil. Too much solder can mask a bad solder connection. If your solder fillets have a convex shape to them, you have too much solder applied - wick the excess away. A good solder joint will have a small fillet with a concave appearance where the solder flows out to a nearly invisible edge on both the solder pad and the component lead. You may not believe how many problems I have fixed simply by removing the excess solder and reflowing solder in the process. At least 40% of the problems builders have are soldering related and at least 40% are toroid lead problems, another 18% are incorrect component placement while the remaining 2% can be attributed to bad parts (usually damaged by the builder). 73, Don W3FPR Len [K4IWL] wrote: I'm hoping that there are still some K1 aficionados out there. I ordered my K1 with the 4-band-filter board. I was not able to get the 4-band-filter to work so I ordered the 2-band-filter (since it's a simpler board) so I could determine if it's a problem with the K1 main board or the filter board. To make a long story short, the K1 with the 2-band-filter works perfectly (40/20M) and the relay switching works. I then finished the KAT and it works with the 2BFB just fine. But here's the problem, I am still debugging the 4-band-filter inbetween using the K1 with the 2BFB. When I plug in the 4BFB there is no relay activity at all when I switch bands. The relays stay in the reset position. I have run out of ideas. Here is what I've done: Replaced the 4MHz resonator. Replaced the IOC with a spare that I have. So far nothing works. I have visually inspected every solder joint. I have reflowed the solder on all the IOC and resonator pads. I have checked continuity between the IOC pins and the relays and they are all solid. I have checked the common connection to all the relays for shorts and opens. I have checked continuity through RFC1. There are no shorts that I have detected or seen on the board (solder splashes, globs, etc.) although I'm not ruling that out yet. Nothing I've done fixes it. Any new ideas out there? Anybody else have this same or similar problem? The relay switching has nothing to do with the RF paths, these appear OK when I manually apply 1.5V to selected relays for the band configuration. RF is getting through as it should on each of the 4 bands. Oh .. yeh ... I am not getting any error codes on the display either. And when I switch the bands with the front panel switch, the display changes but no relays activate. 72, LEN, K4IWL www.qrz.com/k4iwl K2 #848, K1 #1221, Wilderness Radio Sierra (another Wayne rig), Every RockMite imaginable, and a 15M HiMite. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

In the EU anything added to a car, including radio equipment, must also carry an e mark in addition to a CE mark. According to 2004/104/EG, not anymore. A CE Marking plus the correct documentation from the car manufacturer is all that is needed now. vy 73 de toby ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] XG2 - Kit and Drake R7 and Orion II Comparison
Good morning. I finished building an XG2 last evening and used my Drake R7 and Orion II as the test beds for the XG2. Results: The R7 receives the 1 micro volt signals on all three bands better than the Orion II (less RX noise and clearer tone). I did not do the SN calculations scientifically, but to my ear the R7 was the better RX. The R7 will be 30 years old next spring and has not been aligned since the 80s.

Re: [Elecraft] XG2 - Kit and Drake R7 and Orion II Comparison
Tom, Interesting! I've got the XG2 and a R-4C. I was told by Rob Sherwood (of Sherwood engineering) that at 1 micro-volt, the meter should be at S-3 and 20 over when set to 50 micro-volts. Since my rig was nowhere near that and I couldn't seem to make it any better when adjusting it, I packed it up and sent it to Rob to play with. It could also be that my XG2 has some sort of problem too! Guess I should have sent it along for testing! We'll see! Also, just wondering what kind of S-meter readings you were getting at the different XG2 settings from the two rigs.

Re: [Elecraft] XG2 - Kit and Drake R7 and Orion II Comparison
On Thu, 15 Nov 2007 10:40:55 -0600, you wrote: I don't remember exactly, but it was like this: R7 S meter readings were all S9 at 50mv. With the preamp on they were all around 20db over s9. Orion II S meter readings were all around S9 at 50mv with the preamp off and 20 - 30db over S9 with it on. I've just finished the R7 MDS calculations: 80m: -121db 40m: -129db 20m: -129db Remember; the R7 hasn't had any maintenance alignment since the 80s, so I thought the old geezer did pretty well :o) It's not realistic to do MDS calculations on the Orion II rig, because the AGC off setting does not really turn the AGC off. It just sets the decay rate at 1000db per second, which prevents getting good RMS readings from the speaker or headphone connections. I found this out while trying to peak my XV144 RX on random noise with the N-GEN using the Orion II. I finally had to connect the XV144 to an FT1000MP MK V to do the adjustment. Tom, Interesting!

[Elecraft] K2 s/n 4276 Output Power Instability
K2 s/n 4276 Firmware Revision(s): 2.04P 1.09 After having a previous issue with the VCO alignment (p. 61), construction went forward without a hitch. At this point, I figured that any gremlins had been banished. Not so. Another pesky gremlin has reared it's ugly head. During transmitter alignment, the initial 40 meter alignment went down in accordance with the manual's expectations. Receiver pre-alignment was straight forward. Alignment of 20 and 30 meter transmit went fine, then from that point on, it all went downhill and the current issue began. Regardless of which band or power setting, on entering TUNE, the power out readings rapidly vary across the entire scale. These rapidly changing readings are also reflected on my Diamond SK-600 power/SWR meter as well as the readigs on the current meter of the power supply. After a brief bit of time, the power out will sometimes stop fluctuating and settle down to the requested power setting. Might this be a problem with U-6, on the control board? I would appreciate any insight of the possible cause of this issue and suggestions of any possible sollutions. 73's William Smith KC4WVL ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 s/n 4276 Output Power Instability
William, You said 40, 30 and 20 worked once, but not now - that says any problem is in an area shared by all bands. The first thing to do would be to check the coax cables, any adapters and the dummy load for a bad connection. I prefer to reduce any extra things in the setup because they too can be a source of trouble (and they are often overlooked). Connect the K2 using a short piece of known good coax to a known good dummy load and try again. If you continue to have problems, go back to 40 meters (which once worked) and use the Transmit Signal Tracing steps in the back of the manual to determine the failing stage. If you have not already constructed the RF Probe from the supplied parts, now is a good time to do that. We can help further if we know more about the failing stage or stages - right now, all we can say is that something is wrong somewhere - either inside or outside the K2. I would not suspect U6 at this point - if you have a problem with the power control only, take a critical look at the Keying waveshape components mounted on the back of the Control Board (yes, they are part of the power control loop). 73, Don W3FPR kc4wvl wrote: K2 s/n 4276 Firmware Revision(s): 2.04P 1.09 After having a previous issue with the VCO alignment (p. 61), construction went forward without a hitch.

Re: [Elecraft] KAT100 with Ladder Line
Curt, There seems to be a misconception among hams that when using 450 ladder line, a 4:1 balun is the best thing to use. While that may be true in some cases, in many other cases, a 1:1 balun will serve better. It all depends on the feedpoint impedance of the feedline at the shack end, and that has little relationship with the fact that 450 ohm line is being used - i.e. the feedpoint impedance is *not* the characteristic impedance of the transmission line in most cases. The feedpoint impedance looking into the shack end of a multiband antenna can vary from extremely low to extremely high - it all depends on the length of the antenna and the length of the feedline. That being said, I would suggest that you use an Elecraft BL2 right at the output of the KAT100. Try it at the 1:1 setting first, and then try the 4:1 setting to see which produces the better results for each band. It would be informative to measure the impedance into the unbalanced end of the balun with an antenna analyzer on each band - use the setting that does not produce an extremely low of extremely high SWR on the analyzer. Often adding or subtracting a length of feedline will bring the feedpoint impedance into a better range for matching. 73, Don W3FPR Curt Milton wrote: I admit I enjoyed using a KAT100 at FD, but I wonder how much value it would be at my station. For feeding my wire antenna with balanced line, I suspect I need an external balun, that has to go someplace, and better to be attached to one of the tuner inputs. Currently I use a manual MFJ tuner (with its internal 4:1 balun) to operate my wire antenna on 30, 40, 80 and 160m. I can imagine the autotuner being useful here, but I can't envision the balun to use and how to attach it to the KAT100. My other antennas are 2 multiband verticals (80/40 and 20/17/15/12/10), and these are nicely matched where I operate - so not much utility for the KAT100 here. So will a KAT100 make my QSY more seamless, and what balun to use and how to integrate it ? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] KAT100 with Ladder Line
For Field Day this year I had my K2 hooked up to a 130' dipole fed by ladder line. We ran that to a 4:1 balun and a few feet of coax to the KAT100. It tuned it up nicely on all bands. We had no trouble working anyone we called.

Re: [Elecraft] KAT100 with Ladder Line
Using any balun with an unbalanced tuner to feed balanced line can be bad news (your mileage may vary, standard disclaimers apply). Under highly reactive loads, a balun used like this can become quite lossy. There's a couple articles in publications and on the Internet on this, but Cebik's article is one that comes to mind ( http://www.cebik.com/link/l-bal.html ). It's better to run a real balanced tuner like a Johnson Matchbox, the MFJ Balanced Line tuner, or others, if you can.

Re: [Elecraft] KAT100 with Ladder Line
You are quite correct. My favorite tuner of all is a link coupled balanced tuner, and it is L B Cebik's favorite too - low loss and can be configured to match just about anything - series tuning for low impedances or parallel for higher impedances. I have built many over the years. No balun required anywhere. If I were able to bring ladderline into the shack, I would have one of my old balanced tuners with the plug-in coils to match the transmitter to the ladderline - but I can't do that (don't ask!), so I use resonant antennas fed with coax and clean up any required additional tuning with a KAT100. But, one must admit that the KAT100 does offer a lot of convenience to the operator, even though it has some drawbacks - it is not balanced, and for those who are fortunate enough to bring ladderline into the shack, it can be used with a balun. It is a workable solution as long as some cautions are observed to minimize the loss. One cannot defeat the laws of physics, but for those who must use an unbalanced tuner and a ladderline fed multiband antenna, the KAT100 followed by a balun may be an acceptable solution. Adjust the feedline length so as to provide a decent feedpoint impedance at the balun without a lot of reactance, and use a current type balun (a voltage balun just will not work well in this application), and one can get on the air - it certainly is better than no antenna at all. 73, Don W3FPR Goody K3NG wrote: Using any balun with an unbalanced tuner to feed balanced line can be bad news (your mileage may vary, standard disclaimers apply).

Re: [Elecraft] KAT100 with Ladder Line
I've been using Cecil Moore's (W6RCA) No-Tuner with 450 ohm ladder line for about 7 years along with a K2 / KAT-2 and it has been a pleasure to use and pretty effective. It's basically a box of 5 4pdt relays out in the yard that switches in/out combinations of 16, 8, 4, 2 and 1 foot lengths of 450 ohm ladder line to the main 450 ohm feedline to get a close match in the shack, and the KAT2 does the rest. The input to the relay box is fed with RG8X with a bead balun on the coax right at the box input. The idea is to switch just enough extra line in to get a current antinode at the antenna feedpoint for the frequency of operation. For a 80 meter half wave antenna (with 10 meter fan element tacked on), the main 450 ohm feedline is about 85-90 feet long. I've worked/confirmed ~140 countries using this antenna with 12 watts or less (mostly 5 watts). And I'm not much of a dx fanatic. 73, Lenny W2BVH Geoffrey Mackenzie-Kennedy wrote: On Thursday, November 15, 2007 at 7:00 PM, Goody K3NG wrote: Using any balun with an unbalanced tuner to feed balanced line can be bad news (your mileage may vary, standard disclaimers apply).

Re: [Elecraft] KAT100 with Ladder Line
I've been very pleased with my MFJ-974, a true balanced tuner. My measurements of feedline current with RF ammeters indicate that overall it is as efficient as my home brew link coupled tuner with plug in coils. I've used the MFJ tuner with several combinations of feedline lengths and radiator lengths, and I've never failed to get a perfect match on all bands from 80 m to 10 m. I'd like also to mention that Dipole3.exe is an excellent, free, and very easy to use program for modeling a dipole fed with balanced line. You can play with different values of feedline length and radiator length, as well as many other parameters, to determine efficiency and impedance at the transmitter end of the feedline. One source of Dipole3.exe is http://www.smeter.net/software/dipole3.exe .

[Elecraft] computer headset for K2/K3 SSB
I was inspired to try to adapt the headset I use for VOIP to the K2, since I wanted to play with SSB a little. I got the idea from something that W2ENY is selling on ebay :-) I'm writing this up so it's in the archives in case someone else has the idea (and remembers to look). How hard could this be, I figured? Well ... read on. Finding the 8 pin part was easy at Radio Shack. I looked up the pinouts, hooked up PTT to a mono 1/8 jack and AF to another 1/8 jack. I plugged everything in, but got no audio response. That was just weird. I fiddled around with plumbing for a while - I plugged the mic into my laptop and the laptop audio out to the adapter, and that worked. After an hour of pulling out my hair, I realize that the microphone is a noise-cancelling mic, and thus it must get power from somewhere. A bunch of web searching led me to http://www.epanorama.net/documents/pc/multimedia_microphones.html which tells me that the PC standard is to supply +5 on the ring of the connector. I also found http://marc.info/?l=elecraftm=109408122407776w=2 in the Elecraft archives! I should have looked there first. It reminded me that there was +5V on pin 6. So I set about to put a 2.2K resistor in the 8-pin shell and use a stereo jack for the mic. That didn't work, either. Huh? Oh. There's no voltage on pin 6. It turns out that when I installed the KSB2, I didn't strap all the pins in the mic configuration header, just 1/2/7/8. Easy to fix. Hey! That was ... better. But intermittent. I couldn't figure out why. It took another hour or so to discover that I had slightly melted the insulation on the PTT lead in the 1/8 jack and it could short to ground! Also a straightforward fix, once I found it. I'm trying to use this with VOX. I'm not sure I'm going to be happy with the results, though ... we'll see. Mostly, though, I think I prefer CW! 73 de chris K6DBG ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.
