Re: [Elecraft] K3: PSK mixed mode
6 weeks ago I had a machine built to a high spec, I asked for Win XP Pro, but got a call saying Microsoft don't supply a stand alone xp pro os software anymore.

Which is better - it all depends on what you want to do. If the author for the application that you wish to use is worth his salt, then the most recent download of that application will work on Win7 - and will likely run on WinXP (there may be exceptions). But if the application author has not been keeping up with updates in the MS OS migration )legacy applications), those applications may work under WinXP and fail under Win7. So each user must make a choice of the OS to be used. Make that choice based on your need for legacy applications - if you have no need for those, then Win7 is the clear winner.

Re: [Elecraft] Now General RF Issue WAS 160m loop experiment a big failure
On 10/20/2011 6:21 PM, gold...@charter.net wrote: I apparently have a bigger problem with RF in the shack and it has nothing to do with the loop. Hi Don, Your email, and some of the solutions offered, reflect some common misconceptions about RFI, including an earth connection as a solution (it is NOT), and SWR as a cause (it is NOT). The usefulness of noting changes from the original SWR values is that it tells you SOMETHING HAS CHANGED in the antenna, so that you know to go looking for something that is broken. I strongly suggest that you download and study my tutorial on RFI for Hams. Nearly all problems blamed on RF in the shack are really caused by Pin One Problems in equipment where the RF is detected, and by antenna systems that put RF on the outside of the coax. Study http://audiosystemsgroup.com/RFI-Ham.pdf One question to ask is, What ELSE, besides that coax, might have changed between before when everything worked, and now, when I have RFI. Think about cable connections between equipment in the shack that might be acting as antennas to bring that RF that your antennas are radiating into the equipment. And think about this -- your antennas SHOULD be putting a lot of RF in your shack -- they must do this if they are working as antennas. Any cables connected to your equipment will act as receiving antennas. When equipment has a Pin One Problem, the RF current those antennas (interconnect cables) receive will flow into your equipment. Sometimes you can modify equipment to correct the Pin One Problem, but usually the better fix is simply make the cables a lousy RX antenna by adding a common mode choke to them. That's what you're doing when you wind some turns of the cable through a ferrite cores. Study the tutorial to understand this. And when I say study I mean STUDY, don't just read it through once. 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] K2-P3 Interface Project
Eric, Wayne, Alan, K2 owners, PIC experts, et al. As a very satisfied K2 line owner I did recently add the Z1B-K2 Buffer Amplifier and the high-performance P3. The most important part missing now (and with me maybe hundreds/thousands? of other satisfied K2 owners) is a tiny PIC based interface. This K2-Interface should emulate/execute the P3-specific command set of the K3 and the P3-K3 communications protocol, so that the P3 acts as a best possible integrated extension of the K2 (integration as far as technically/economically reasonable). If I understand aright the situation at Elecraft, they don't aim now/further on to allocate any resources to realize this project. So could this definite project eventually be done by students/trainees (to intern at Elecraft or at a college of technology)? Another solution could be to outsource this project to a well skilled/equiped PIC expert? If such a solution should be sponsored, could a call for donations be published on this list server? Contributions and proposals to realize this project (quickly...) would be very appreciated. 73, Heinz HB9BCB __ 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] Spot button QSYs K3
I spent some more time with this and find that if I tune to the low side (tone lower than my pitch setting) and push spot it tunes the way it should but if I turn the dial to hear a higher note than my 680 hz pitch setting the VFO takes off down the band. It will sail right past S9 signals without stopping. I have 250 and 500 hz filters installed (both 8 pole) and my DSP width set at 350 where I normally have it. I am using version 4.39 as previously mentioned. My sub RX is off. I don't like turning the P3 off because it's like going blind but doing so has no effect on the problem. Pressing TEXT DEC I have AUTO OFF and Threshold set to 1. Setting it to a higher value does not give me a relialbe tuning bar. VFO CRS is set to 0.1 VFO CTS is set to 400 VFO FST is set to 50 VFO IND is set to NO VFO OFS is set to ON Pitch is set to 680 but other settings have produced similar results. I don't always use SPOT as the P3 allows me to tune just as accurately and I am usually already looking at it. I did not notice this SPOT problem before my last F/W upgrade although it could be a coinsidence. -Robby VY2SS -- View this message in context: http://elecraft.365791.n2.nabble.com/Spot-button-QSYs-K3-tp6908448p6916742.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] 160m loop experiment a big failure
I use only open-wire fed antennas here. I have 3 feedlines that come right into the shack to balanced tuners (Palstar BT1500A) and run the legal limit with few RFI problems. My house is in the middle of a large rhombic (unterminated) antenna. I don't have a station ground other than the AC safety ground at my shack. My shack is in the basement but Ive had this same setup on the second floor with good results. IMO, an outside ground thats brought to the 2nd floor is not needed and in fact will cause problems. If I had any coax feeds I would follow the SPG design for lightning protection but with open wire I have disconnects where they enter the house and ALWAYS disconnect and ground them (common ground to AC entrance) about 20' from the house. A balanced tuner will help a lot. Open-wire feedline probably isnt the cause of your RFI. It sounds like you may be on to something with your latest post. 73, Steve -- View this message in context: http://elecraft.365791.n2.nabble.com/160m-loop-experiment-a-big-failure-tp6895962p6916843.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

First things first: cobble up a good star-system for tying everything together with short fat wire or strapping to get all the chassis at the same RF potential. Then kill off the common mode currents that run on the outside of your coax; I've had great luck with RF isolators from http://www.radioworks.com/ct-4.html I have one between K3 and amp, and another between my tuner and the balun that goes to my antenna system. I have a simple counterpoise system from the second-floor window to the garage roof, and that connects to the cold side of the balun. It is also where the outside grounding system connects. If there are still some strays, you can use snap-on ferrites, but I have found in a couple of different installations that once the common-mode currents on the coax are dealt with, there aren't any further RF problems. Steve also mentions that his shack is in the middle of a rhombic antenna, which suggests that your loop arrangement may work fine once you get the shack setup tamed. 73 and good luck, Tony KT0NY -- http://www.isb.edu/faculty/facultydir.aspx?ddlFaculty=352 __ 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] KX3 dimensions?
Hi All, Shortly after the KX3 was announced and described, I started contemplating just what radios I own that it could replace. Several radios I own were obvious candidates for replacement, but the FT-817 wasn't immediately that obvious. That was due to the exceptionally small size of the FT-817, plus it's equally exceptional all band capabilities. However, I did a rough calculation of volume for each radio, and I came up with approximately the same results that Wayne has posted (his calculations are surely more precise than mine). The KX3 is, indeed, smaller! It's perhaps a bit counter intuitive when you just look at the two, since the KX3 is wider and higher. The weight differential, which favors the KX3, is substantial. Performance wise, I'm sure the KX3 will blow the FT-817 away. Different people will have different priorities, so there's no right answer. For me, the FT-817 will probably lose 95% of it's appeal once I get my hands on a KX3. The concession will be access to VHF/UHF, but I find my HT to be more than adequate as a supplement, and what I use mostly anyway. Besides, I've always felt the FT-817 was almost too small--the display is hard to read, and the controls are difficult to access. I've never liked the menu system on most Yaesu's anyway. Still, my FT-817 has been a very frequent companion for me. It's been a relatively flawless performer for a good while, and well worth every nickel I spent on it. It's no surprise to me that this has been one of the most successful pieces of ham gear ever produced. Nevertheless, the KX3 looks to me like the perfect radio for QRP Field Day and similar activities. I will be most interested to see how the HF Packer folks respond to the KX3. I'm not one myself, but they are a very innovative group when it comes to implementing small radios. Since radios like the FT-817 and IC-703 are relative power hogs compared to the KX3, I suspect that will be another very significant factor. It's always a lot of fun watching these folks do their thing, as was the case most recently at Pacificon. Bonnie, KQ6XA, was putting out a very potent signal with her setup at Pacificon, and knocking off contacts one right after another. She was getting better signal reports than I was using my 100 watt mobile setup! Anyway, I can already visualize how HF Packers will fabricate a way of mounting a KX3 in front of them and having substantially enhanced operating ergonomics in the process.

Re: [Elecraft] KX3 dimensions?
Hi Dave, I did a presentation at the Pacificon HFpack forum titled HFpack Lite and the Elecraft KX3, in which I proposed a 5-pound (total) variation on HFpack. It is based on the KX3, a very lightweight antenna, external Li battery, and a hypothetical mic-on-steroids that could control the radio while it is in the backpack -- including turning it on/off. The talk was very well received, with lots of input on possible antennas, etc., from the audience. Bonnie was there, and later stopped by our booth, which I interpreted as a celebrity endorsement. I'd be happy to send you my powerpoint presentation, although it is long on illustrations and short on explanations. You'll have to use a bit of imagination. 73, Wayne N6KR I will be most interested to see how the HF Packer folks respond to the KX3.

Re: [Elecraft] KX3 dimensions?
By very lightweight antenna, do you mean the aforementioned 1oz of 26 gauge wire with the also aforementioned 1oz fishing weight? I'm really going to have to do something king on pedestrian mobile, or pedestrian portable. The loop I got (mentioned earlier) looks like it'll be great for portable, easy to set up if you're not going to move around a lot, but not so easy to walk with fully deployed.

It is based on the KX3, a very lightweight antenna, external Li battery, and a hypothetical mic-on-steroids that could control the radio while it is in the backpack -- including turning it on/off. The talk was very well received, with lots of input on possible antennas, etc., from the audience. Bonnie was there, and later stopped by our booth, which I interpreted as a celebrity endorsement. I'd be happy to send you my powerpoint presentation, although it is long on illustrations and short on explanations. You'll have to use a bit of imagination. 73, Wayne N6KR I will be most interested to see how the HF Packer folks respond to the KX3. I'm not one myself, but they are a very innovative group when it comes to implementing small radios. Since radios like the FT-817 and IC-703 are relative power hogs compared to the KX3, I suspect that will be another very significant factor. It's always a lot of fun watching these folks do their thing, as was the case most recently at Pacificon. Bonnie, KQ6XA, was putting out a very potent signal with her setup at Pacificon, and knocking off contacts one right after another. She was getting better signal reports than I was using my 100 watt mobile setup! Anyway, I can already visualize how HF Packers will fabricate a way of mounting a KX3 in front of them and having substantially enhanced operating ergonomics in the process. As Terry, WA0ITP says, I love this stuff! Even as a spectator!

Re: [Elecraft] Re ham shack computers...
There is also the question of whether older ham applications will work correctly on the newer OS, but then there's the question of whether the latest versions of ham software will work on older XP-based machines.

[Elecraft] KX3
Hi Wayne, I already put in a vote for this with Eric, but wanted to ask if there would/could be some way to: 1. Add an external preamp for 6m, as is done with the K3. If I am to use this as a portable radio for 6m EME DXpeditions, it will be imperative to be able to add a preamp in the receive line. 2. Control the PTT line on the KX3 from the computer's Serial Port RTS or CTS lines. JT65A switches the radio into transmit by first raising RTS and CTS lines on the computer's serial port. After about half a second the JT65A tones begin, leaving enough time to switch the antenna relays and turn on the amplifier without hot switching anything. This works great in the K3, and I hope there will be the same logic in the KX3. Please let me know if you are making, or have already made provisions for these, or if I am better off to look elsewhere for a more portable rig than the K3.

If I am to use this as a portable radio for 6m EME DXpeditions, it will be imperative to be able to add a preamp in the receive line. We can't tap into the KX3's internal RX path directly. However, a preamp could be inserted externally in conjunction with a T/R switch. We have enough general-purpose outputs on the KX3 to control such a unit. Also, we're looking into the possibility of integrating a 6- meter LNA into the BPF array to obtain a very low 6-m NF. 2.

Re: [Elecraft] K2-P3 Interface Project
Hi Heinz, K2 support for the P3 has been on my list for a long time. I have a K2 with RS-232 interface option and the Z1 kit which I still need to install. There are a couple other features ahead of it in the list, but I would really like to get to it. When it happens, it will only require a firmware upgrade to the P3. The K3 has several P3-specific commands that don't exist in the K2. That means in particular that fixed-tune mode is not possible with the K2. Also the K3 uses a special protocol to talk to the P3 which is not implemented in the K2. However, I think I should be able to get reasonably-good integration between the two so that you can read out the proper frequency on the P3 display, click-to-QSY etc. 73, Alan N1AL On Fri, 2011-10-21 at 12:24 +0200, Heinz Bärtschi wrote: Eric, Wayne, Alan, K2 owners, PIC experts, et al.

[Elecraft] K3: PSK mixed mode
You can find suitable XP-Pro machinces for well under $100 at PacificGeeks.com. I purchased a refurbished HP PC with one serical and one parallel plus a handful of USB ports for $59.95 recently. I'm a broadcast engineer (electronics and IT) for a nation-wide company where we still use XP on older machines and purchase new ones with Windows 7. XP is not yet dead and will continue to be viable even after Microsoft stops supporting it. However, when one can't find up-to-date antivirus and firewall products for XP I would stop using it on-line. Off-line use will remain safe. I have three computers with Vista and have had no problems with any of them. One is my TV DVR, gets used for browsing, and has been 100% reliable for over three years. I also use Windows 7 which is no more or no less stable than Windows XP. Some ham radio programs are less stable on Windows 7 than Windows XP, even with an appropriate installation to avoid the more current security issues (UAC).

Re: [Elecraft] OT- Coax for ground wire?
For RF, you want the lowest possible inductance in the ground lead since inductance has reactance and reactance is what you do *not* want. For a given length, a bigger conductor has lower inductance. I don't know why full coax would not be as good as just the shield, although it is a lot more bulky. The center conductor is a relatively small wire, so it would not carry nearly as much of the RF current as the outer braid due to its reactance. I'd not expect any benefit from connecting it. There might be a slight advantage to having the braid round (on the coax) rather than flat. I've not investigated that. FWIW, in my installation I run a 100+ foot inverted L that terminates at a shelf in the shack above the rig where I have a large, manual, L-net tuner. All the equipment is tied together and then to ground. I use a sheet of copper mounted on the wall (with thumbtacks) behind the rig and tuner that runs to where the outside ground comes through the wall. The equipment all connects to this copper sheet through short wire pig-tails. Got the copper sheet for a few bucks from a hobby store. It's about twice the thickness of heavy-duty aluminum foil and came in a roll several feet long. 73, Ron AC7AC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of W8JH Sent: Friday, October 21, 2011 11:05 AM To: elecraft@mailman.qth.net Subject: [Elecraft] OT- Coax for ground wire?

A good practice with any antenna installation is to check the SWR on each band for which it is used, and make a note of that. While in Comm Officers' School at Keesler AFB many years ago, I was active in the radio club [K5TYP]. We had a tribander up about 40 feet or so that never worked. We borrowed some test equipment and measured the impedance on 20, 15, and 10, and it was almost exactly 50 ohms [and the same on all bands which should have been a clue]. After several weekends of work including several trips up the tower, one of the guys said, Let's do this one more time, and cranked the frequency of the impedance bridge down to 20m again. Nothing changed. The bridge saw 50 ohms at 14 MHz, 15 MHz, 18 MHz [which wasn't a ham band then], ... everywhere else, including 80m. We finally figured out we had the longest 50 ohm dummy load in Harrison County. I'm not real clear on how faulty coax could cause his RFI symptoms, unless maybe none of the power is actually getting to the antenna and is backing up [a technical plumbing term] into the shack. That it started with the propane tank episode is certainly suspicious.

I have a K2 with RS-232 interface option and the Z1 kit which I still need to install. There are a couple other features ahead of it in the list, but I would really like to get to it. When it happens, it will only require a firmware upgrade to the P3. The K3 has several P3-specific commands that don't exist in the K2. That means in particular that fixed-tune mode is not possible with the K2. Also the K3 uses a special protocol to talk to the P3 which is not implemented in the K2. However, I think I should be able to get reasonably-good integration between the two so that you can read out the proper frequency on the P3 display, click-to-QSY etc. 73, Alan N1AL __ 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

Take a antenna analyzer and put it at the end of the coax. Regardless of the reading, run your hand up and down the outside of the coax. If the shield is open or bad, the readings will go all over the place.

Re: [Elecraft] OT- Coax for ground wire?
I think Jim accidentally reversed his meaning about ground lead inductance. Lowering the inductance of the ground connection does *not* lengthen the effective radiator or add loss. Allowing the ground system to be part of the radiator by letting the ground lead have significant inductance and so add to the overall length of the antenna system may well increase losses and promote coupling to house wiring, etc. That's good reason to use a low-inductance ground connection. When running an end-fed wire as I do, it's useful to keep the rig chassis at a low RF potential. If the rig is allowed to have significant RF voltage on it (as when the feed point of the wire is near a voltage loop), the rig adds my body to the active antenna, changing the tuning. Also, significant RF voltage floating around the DC supply chassis (because it's connected to the rig) can do weird things to the voltage regulation if a junction in the regulator starts rectifying the RF. In my case the copper sheet terminates in an RF ground system that enters through the wall a few feet from the operating position, so extending the sheet to where it enters ensures that the entire copper sheet stays at a very low RF potential at all times, and having the sheet extend behind the equipment allows very short ground connections to each chassis, keeping everything at the same low RF potential. 73, Ron AC7AC -Original Message- On 10/21/2011 12:25 PM, Ron D'Eau Claire wrote: For RF, you want the lowest possible inductance in the ground lead since inductance has reactance and reactance is what you do*not* want.

[Elecraft] North American SOTA Day - 10/22/2011
Tomorrow is North America's Summits on the Air (SOTA) Day. There will be a much larger than usual amount of SOTA activity tomorrow in the US and Canada. Over 30 different summit activations are already publicized, and more are being added hourly. These stations will be set up on prominent mountain tops. The hams hiked there and set up portable stations, and a lot of Elecraft rigs will be heard. I use a K2 and wire antennas. The activations will start around 1400z and run throughout the day. The SOTA Watch site, www.sotawatch.org, lists the activations - The Alerts page lists those planned, and the Spots page shows the spots for those already on the air. More information about SOTA can be found at www.sota.org.uk. Chasing summits is an informal and very enjoyable ham radio activity. Why not join in by working some summits tomorrow! As the SOTA Watch site shows, the activations are often centered around QRP frequencies. There will be activations from HF through VHF/UHF, with FM, SSB and CW operation. Keep track of the stations that you work - you can log them into the SOTA database and work toward certificates and trophies. It's fun - give it a try!

Most sheet metal shops can sheer copper sheets into almost any width one would want, and the cost is reasonable. I had about half of a 4 x 8 sheet sut into 1 and 2 inch x 4 foot strips several years ago and that's used throughout my station's grounding system. 73!

[Elecraft] K3 Transmitter Gain Cal Failure at 1mW with KXV3a
Hello K3 Support, I installed the KXV3a tonight into my K3 and when I went to do the Gain Calibration it failed on 6 Meters as it was unable to get the required output. Any idea why this output could be low on this band (I believe it only reached an 8 out of the expected 10)?

Re: [Elecraft] K3 Transmitter Gain Cal Failure at 1mW with KXV3a
If you have an external wattmeter (a lot of antenna tuners/dummy loads should have this), then go through the wattmeter calibrations to ensure your internal wattmeter is reading correctly. -Original Message- From: n2...@aol.com Sent: Friday, October 21, 2011 7:54 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 Transmitter Gain Cal Failure at 1mW with KXV3a Hello K3 Support, I installed the KXV3a tonight into my K3 and when I went to do the Gain Calibration it failed on 6 Meters as it was unable to get the required output.

Lowering the inductance of the ground connection does*not* lengthen the effective radiator or add loss. No, I didn't accidently reverse my meaning. You missed my point. ANY length of lead in the ground wire adds inductance. The difference in inductance between a #22 wire and RG8 isn't enough to matter. Repeat after me (or write it 100 times on the blackboard). A connection to earth has NOTHING to do with RF ground, nor does it cure RFI issues, nor does it make an antenna work better. What DOES matter (a lot) is the connection of a cable shield to the shielding enclosure of equipment. 73, Jim 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

Re: [Elecraft] K3 Transmitter Gain Cal Failure at 1mW with KXV3a
Michael, 1. Is the dummy load rated for 50 mhz plus 10-160m? 2. Is the dummy load rated for at least 50 watts? I'm guessing yes since it passed the other bands with the KXV3. 73 Delwyn KH6DC -Original Message- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of n2...@aol.com Sent: Friday, October 21, 2011 4:55 PM To: elecraft@mailman.qth.net Subject: [Elecraft] K3 Transmitter Gain Cal Failure at 1mW with KXV3a Hello K3 Support, I installed the KXV3a tonight into my K3 and when I went to do the Gain Calibration it failed on 6 Meters as it was unable to get the required output.

[Elecraft] Elecraft SSB net announcement
The weekly Elecraft SSB net will meet Sunday (10/23/11) at 1800Z on 14.3035 MHz +/- QRM. I will be net control from western Oregon, and we'll try relays to pull in the stations that I can't hear. Saturday, I will be on a summit in the central Oregon Cascades for NA SOTA day. Hope to hear some of you. Check SOTA Watch at www.sotawatch.org. See you there. 73, Phil, NS7P __ 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
