[Elecraft] KX1 Tuner
Hello, My KX1 has been having problems getting a low SWR. At home I had a long wire strung out the up stairs window getting 1.2:1 to 1.6:1. I took the same wire with me on a trip and now I cannot get the Antenna Tuner to tune. I'm getting 9.9:1 on both 20 and 40m. I'm in Anchorage Alaska and I'm not receiving any signals as well. There must be some on 40 meters I would think. The only difference is that I broke one of the wire connectors from the wire so I tried attaching bare wire to the antenna connector. I did a inductor/capacitor relay check using a dummy load on 20 and 40m and this is what I have found: 20m Watts SWR L0 .6 1.0 L11.2 2.1 L21.2 9.9 L3 .9 7.9 C0 1.0 9.0 C1.7 7.3 C2.6 7.0 C3.5 5.8 n1.6 1.0 n2.5 1.0 40mWatts SWR L0 1.1 1.0 L1 1.0 1.2 L2 1.2 2.1 L3 .9 6.0 C0 1.0 3.2 C1 1.0 3.0 C2 1.0 2.8 C3 .8 3.1 n1 .5 1.0 n2 1.01.0 I am away from home and was planning taking the KX1 camping next week. I have no access to any equipment for the time being so it looks like I may ended up leaving the radio in the car. Your thoughts would be appreciated! 73, Ed ke7hga -- View this message in context: http://elecraft.365791.n2.nabble.com/KX1-Tuner-tp5481513p5481513.html Sent from the [KX1] 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
[Elecraft] Twisted Pair Wiring and RFI Rejection
When I was considering wiring for my new station control panel, I decided to "harvest" twisted pair from Cat-5e to use as hookup wire. I was aware that it would reject low-freq noise and hum without shielding. Having a large amount of Cat-5e didn't hurt, either. I believe Cat-5e is isolated up to 100-KHz. I have not taken photos to post to my website, but have a webpage established for the control panel project. http://www.kl7uw.com/controlbox.htm For a teaser: It uses a four-stage sequencer for VHF operations, built-in computer soundcard interface. 17 switches and 22 DPDT relays to control preamp, amps, relays, remote power supplies, keying to interface SO2R operation. With this I control 17antennas on three towers and one dish and equipment on bands from 600m to 3cm. All in a 3x8x6 inch enclosure. High-tech twisted-pair! ;-) 73, Ed - KL7UW Message: 33 Date: Mon, 30 Aug 2010 08:11:09 -0700 From: "Jim Brown" Subject: [Elecraft] Twisted Pair Wiring and RFI Rejection To: "elecraft@mailman.qth.net" Message-ID: <20100830151107.e8c1358...@gw1.nlenet.net> Content-Type: text/plain; charset="us-ascii" On Mon, 30 Aug 2010 10:14:14 +0100, David Woolley (E.L) wrote: >That's another of Jim's suggestions that the UK amateur radio trade >and RSGB shop have failed to take note of. I don't want to take credit for repeating fundamental principles that have been well understood for at least a century. The great telephone companies began using twisted pairs for both short and long lines early in the 20th century. In the early days, the only source of interference was 60 Hz power, so wires were run as parallel conductors, with the twist in the form of a crossover every other pole. This worked fine, because it was much much shorter than the wavelength of the 60 Hz power, and telephone lines were able to run directly under power lines without interference! Today, CAT5/6/7 cable rejects noise SOLELY by virtue of its high quality twisted pair construction. Crosstalk is further reduced by the fact that the pairs are twisted at different rates. These fundamental principles are WELL understood in the EMC world, and those of us working in EMC in pro audio have had to learn them to keep hum, buzz, and RFI out of our systems. I find it ironic that RF folks look down on audio engineering, because "it's only 20-20,000 Hz." In fact, audio systems are far more complex than RF systems -- they span 3 decades of frequency, require transducers that can produce high power over this wide frequency range with controlled dispersion far more complex than most antenna systems, must work in an acoustic environment that is at least as complex as the ionosphere, have dynamic range requirements of 100 dB or more, and must regularly achieve that with signal levels in the millivolt range in an environment that is full of all sorts of electrical noise. 73, Jim Brown K9YC 73, Ed - KL7UW, WD2XSH/45 == BP40IQ 500 KHz - 10-GHz www.kl7uw.com EME: 144-QRT*, 432-100w, 1296-QRT*, 3400-fall 2010 DUBUS Magazine USA Rep dubus...@hotmail.com == *temp __ 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] K2 KPA/100 excessive power issue, SSB mode, some bands
Thanks much for the comments, all were very helpful and are much appreciated. I did some further testing along the lines suggested with the following results: Settings: SSBA = 1; SSBC = 3 to 1; requested power QRP = 2, QRO = 20; transmitting into a dummy load; microphone = Heil HC4 (but similar results have generally been experienced with Icom electret hand mike, HM 36); all bands tested in both TUNE and SSB modes . Generally in QRP on TUNE mode, I saw anywhere from 2.8 to 2.3 watts after the ALC had time to settle in (the ALC seems to start over with any change in band or certain other settings). In particular, I saw 2.8 watts on 160, 2.3 on 10 meters, with the other bands somewhere in between. In SSB, I generally saw peaks at one or two bars, with an occasional third bar, for ALC; and two bars with an occasional third bar for RF. The exceptions were: 80 meters, where there was a very brief initial surge up to 4 or 5 bars before settling in at 1 to 3 bars for ALC, and 2 to 3 bars for RF; 40 meters, where again there was the initial surge in reading before settling at 3 to 4 bars for both ALC and RF; 30 meters where the results were similar to 40 meters except that RF eventually settled to only 2 to 3 bars. Then switching to QRO, on Tune mode, I saw 19, 20, or 21 watts on all bands except on 80 meters where the ALC never seemed to settle in and kept bouncing around between 18 and 22 watts, with 19 being the most stabile eventual reading. In SSB, I generally saw peaks at 1 (10 and 12 meters), 1 to 2, or 2 to 3 (160) bars for ALC and 2 to 3 bars for RF. On 80 meters, however, there was again an initial surge, lasting a little longer and settling in a little slower to an eventual 2 to 3 bars for ALC and a solid 3 bars of RF; on 40 the initial surge was more extreme with the ALC kicking up as high as 6 bars before settling in at 3 to 4 bars, 2 to 3 bars for RF. The most extreme results were on 30 meters where I saw readings as high as 5 to 6 bars for ALC and 7 to 10 bars for RF. After a much longer period of speaking into the microphone, eventually readings settled respectively to 3 to 4 bars with a rare 5th bar and 2 to 3 bars with an occasional 4th bar. I should add that I can generally get a bit higher readings by screaming into the microphone, but the results summarized above were obtained by speaking just a bit louder than normal, as if I am excited on the verge of working a new, rare DX entity. Generally a higher RF reading was supported by a higher ALC reading. Does this indicate that any excess in power output is not likely to be an ALC problem rather than a KPA/100 problem? How necessary do you think it is to install the KPA100UPKT given these results? Any observations or suggestions would be appreciated. 73 Ken - Original Message - From: "Don Wilhelm" To: "Ken Cannaday" Cc: Sent: Friday, August 27, 2010 12:00 PM Subject: Re: [Elecraft] K2 KPA/100 excessive power issue, SSB mode, some bands > Ken, > > That description sounds suspiciously like you are developing a parasitic > on 40 meters. > Yes, the first step in getting that under control is to install the > KPA100UPKT. > It was developed specifically to address a problem very similar to yours. > > There is another possibility (since you mentioned the SSBA and SSBC > parameters) - that you are driving the mic input too hard. switch the > display to read ALC.

Re: [Elecraft] K2 KPA/100 excessive power issue, SSB mode, some bands
Ken, This is behavior that is typical after the KI6WX SSB RF Gain mod has been installed. Whether or not you have installed that mod, try the following changes to the KSB2 board: 1 - Change R9 to 15k 2 - Cut the trace (on the top of the board) between P1 pin 6 and the base of Q1 and insert a 1k resistor between those two points. You will have to orient the resistor vertically, or use an SMD resistor. That should calm the ALC overshoot when operating into a dummy load. The question still remains about the original problem which was an overshoot problem on 40 meters. If that persists when operating into an antenna, the KPA100UPKT is the solution. 73, Don W3FPR On 8/31/2010 6:54 AM, Ken Cannaday wrote: > Thanks much for the comments, all were very helpful and are much > appreciated.

Re: [Elecraft] KX1 Tuner
Ed, you didn't mention the length of the wire you are using. Certain lengths will present an impedance outside of the range of the tuner - especially the KX1 tuner. The KX1 doesn't have as much matching range as other tuners. The L and C combinations had to be limited to fit it into the tiny space. It's not unusual for a wire to tune very differently when moved from one place to another. Nearby objects can have a large effect on its electrical length and so its resonant frequency. I'd try a different length of wire - if you don't want to cut the wire, just fold back some of the far end a few feet along itself. Even if insulated, such a wire then looks like one thicker wire to RF since RF does not flow through the conductor, but travels along the outside of it as a wave. Bare wire is fine for an antenna, provided it's not touching any other conductors. Even insulated wire should be spaced well away from conductors. And be sure your bare wire connected to the center conductor isn't shorting to the outer metal ring of the antenna connector. Ideally you'd have a second wire attached to the KX1 case (or the shiny outer ring of the antenna connector) to act as a counterpoise. More than one wire attached to the case is even better. If they're elevated off of the ground, one for each band 1/4 wavelength long is the best. That would be 33 feet for 40 meters, 16 feet for 20 meters, etc. If they're lying on the ground the length is unimportant. The ground will detune them anyway. In that case the more the better.

Re: [Elecraft] Give us a network interface
My thought exactly. I think we would rather be ahead of the curve on this one. Serial(RS-232) will become more and more difficult on the x86-64 platform. It might not be the most cost effective but what about fiber optics? Fiber optic PC cards are getting cheaper($100-$200) and fiber would introduce no RFI into the K3. That is just one idea. I personally would be happy with CAT6 cable. Re: [Elecraft] Give us a network interface >From my perspective, I see serial interfaces as increasingly problematic due to unavailability. PC motherboard manufacturers are dropping serial ports due to a widespread lack of use and interest. And as many have noted, USB to serial converters can be a PITA. My current Mobo, which is about 3 years old and due for replacement this winter, has one serial port that exists on some header that is not brought out to the rear panel. Finding a PCI RS-232 serial board for it that had Win 7-64 drivers was a challenge.I only found one. When Win 8 comes around next year the number of supported serial boards could easily become zero. PCI slots are also on the way out, many current high end boards now only include one "token" PCI slot with the rest of the slots being some flavor of PCI-E None of the current issue motherboards I'm considering for my next station PC include a serial port or more than one PCI slot. So, I'm sorry for those who find serial ports warm and comforting, but they a about to join paper tape punches/readers, 8 inch floppys, and CRTs on the list of quaint old technologies that are no longer manufactured or supportable. In the meanwhile, rigs and other station equipment are ever increasingly interconnected and interdependent (read "networked"). Clinging to serial ports is not really a viable option going forward, neither in terms of providing the desired functionality nor of being supported by general market hardware/software suppliers. TCP/IP over Ethernet wouldn't exactly be a giant leap into the future but it is already supported by any number of ham applications for networking and for internal communications between modules. In the meanwhile I'm really glad to have LP_Bridge and the MicroHam Router so the station works almost like it had a real network. 73 Jack KZ5A K3 #4165 -- Nicholas W.

Re: [Elecraft] Give us a network interface
As long as PCs have USB ports, and as long as there are USB to RS232 adapters available, then the K2, K3, and other rigs having RS232 control will be 100% supported. No one need worry about installing an RS232 card in their computer. Future Elecraft products will have additional I/O options, possibly including USB and/or Ethernet, but I can't make predictions beyond that. It is also possible for the K3's present digital daughter board to be replaced with one having USB, Ethernet, or a combination of I/O ports. We might look at this. Of course we would continue to offer the existing unit, with RS232, as long as there is a need for it.

In essence, the ability of twisted pair to reject HF noise is directly related to the number of twists per inch, and the uniformity of the twist. The close spacing of the twist also helps. High quality twisted pair like any of the CAT5/6/7 cables continues to reject noise well into the VHF range, although the degree of rejection degrades with increasing frequency. Noise rejection is also a function of the balance of the receiver, and to some extent, the balance of the output stage that drives the line. CAT5/6/7 cables as a group are constant impedance (100 ohms) and have relatively good bandwidth (well into the tens of MHz). Like any transmission line, loss increases with frequency. 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] Give us a network interface
There are PCI-X multiserial cards available that plug into the forward section of PCIx16 video slots. These are readily available and PCIx16 is not going away anytime soon being a very popular video format. The demise of serial ports is overstated. Thankfully the serial port is not being pushed by new game designers, extending speed and changing behavior to suit a new game every other week like USB. Worry about this interface when video card people give up on PCIXnn slots. Industrial users are interested in spending money on new equipment and then using it for free for twenty or thirty years. It is the extremely expensive industrial peripheral equipment that will keep serial ports in use for another decade or two. If it costs them money, industrial users would just as soon Microsoft walked off a cliff. Their engineers are really nasty about spending money based on someone else's consumer-grade eye-candy. There's hope-you-will-buy-my-new-gizmo salesmen TRYING to drive a market, and there's financial reality. There is a REASON why TV graphics are confined to a 4x3 box on a high def 16x9 presentation of a sports game. MOST people are watching on a converter ahead of a 4x3 box. My wife has our 16x9 TV in the game room on the PS3. According to her, I have to wait for the big 31 inch 4x3 to fail before putting up a 50 inch in the living room. The set has a super-video input fed with a digital converter that has S-video out, and it is actually very sharp. The marketeers don't want you to know what you can so with S-video and a converter box. They don't want you to know about serial ports either. No volume in it. No money. Wierdness with my K3 connected to my computer went away when I quit using USB in favor of a PCIX serial card. I picked serial 1 and 2 which are assigned by the OS at bootup, not juggled in the air, depending on whatever in the USB way. A whole bunch of now and then weirdness that would never trouble-shoot just went away and the serial ports just run. No wheezes, no dropouts, no weirdness, no drop connects, no freezeups, no nuthin.

[Elecraft] K3 Firmware Download Warning
Yesterday, I downloaded the most recently-relased firmware updates for my K3. After the download, the rig went dead in the water. After three hours of work with Dale at Elecraft, we determined that the newest firmware available on the website has major compatibility issues with some, if not all recent K3's. After re-installing the 3.97/1.09/2.58 packages, all was well again. Dale tells me he has had three cases of this incompatibility recently. This is just a warning to think twice before downloading the latest and greatest, until the good folks on the West Coast get all the bugs out!!

[Elecraft] Foreign Currency Exchange
Please excuse this comment as I receive the reflector as a digest. My wife works as an agent for Dubus Magazine published in Germany. The cost of paying exchange fees for every subscription would be prohibitive for both the subscriber and publisher on an individual case. Dubus solution is having national representatives who process subscriptions in their native currencies. The rep then periodically sends a bulk payment that lowers the per-unit exchange cost immensely. You probably have seen the tag on my signature line for Dubus. We are listed as the US rep but accept both Canadian and Mexican subscriptions paid in US funds (there are not too many of these). This is how some businesses handle this.

Re: [Elecraft] Give us a network interface
Wayne, I am concerned about any modifications that impact low-noise and MDS performance, but can see advantages of Ethernet connection for future applications. I would entertain an external Ethernet module that would talk thru the existing K3 RS-232 interface if this is practical. I am not knowledgeable of computer communications (just a user) to know if this is a good approach. I currently have both a computer with serial port and use the prolific USB/serial cable with another computer (with no problems). Last week I uploaded new firmware using the USB cable. Computer technology is moving quickly, so I would not be surprised to see USB use fading and some more advanced interface take its place. A real challenge in the SDR environment. -- Message: 2 Date: Tue, 31 Aug 2010 08:41:44 -0700 From: Wayne Burdick Subject: Re: [Elecraft] Give us a network interface To: Nicholas Farrar Cc: elecraft Message-ID: Content-Type: text/plain; charset=US-ASCII; format=flowed; delsp=yes As long as PCs have USB ports, and as long as there are USB to RS232 adapters available, then the K2, K3, and other rigs having RS232 control will be 100% supported. No one need worry about installing an RS232 card in their computer. Future Elecraft products will have additional I/O options, possibly including USB and/or Ethernet, but I can't make predictions beyond that. It is also possible for the K3's present digital daughter board to be replaced with one having USB, Ethernet, or a combination of I/O ports. We might look at this.

I recently hooked an ALS-600 and ARI-500 to my K3, and let me tell you, a 600w, band switching solid state K3 is pretty darned nice, hi. 73, Don, WB5HAK __ 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] P2 anyone ??
I for one would really like to see a panadaptor for the K2. In an EC2 sized enclosure. Any others interested?

Re: [Elecraft] P2 anyone ??
Bill, The P3 already handles the K2 IF output, in fact, it handles anything from 455 kHz through 21.7 MHz. It is not available in the EC2 enclosure, but you are invited to squeeze it into that if you have sufficient desire (you will have to re-design the front panel). For use with the K2, you will need to bring the IF out to a rear panel connector. Jack Smith www.cliftonlaboratories.com has already solved that with his Z1B-K2 buffer amplifier. 73, Don W3FPR On 8/31/2010 9:18 PM, able2...@aol.com wrote: > I for one would really like to see a panadaptor for the K2.

The first "pre-P3" panadapter prototype was actually built in an EC1 cabinet. It had a cute little 64x128 monochrome back-lit display, and a knob and seven buttons on the front panel.

[Elecraft] [K2] No Transmit Power
Don: While I had to use my 50 MHz scope to take the RF readings, the big signal drop you told me to look for seems to be at the Pre-Driver output. Instead of .120 Vrms, I am looking at about 0.20 Vrms or less. Not much difference when Tune is pressed (key down). The T-R switch output is also very low but is (apparently) supposed to be. I have checked all resistor values for the Pre-Driver amplifier circuit and they are all correct markings. Tomorrow I will concentrate on those solder joints as well T1 and T2.

Re: [Elecraft] P2 anyone ??
(Giggle...) I think it actually would be possible to home-brew your own P2. Just buy a P3, take it apart, and mount the components in an EC2 chassis. The LCD display looks like it would just barely fit - you'd have to come up with some way to mount it to the front panel. The Front Panel PC board would probably have to be mounted at an angle so that the flex PCB cables that come out of the LCD can reach while still having access to the connectors on the back (bottom) side. You could wire up the switch contacts to mechanical switches on the front panel. I think it would be cool if someone did that. I just want to see the look on the face of the Elecraft customer service technician when you send it in for repair!

Hmmm... would it come with one of those big magnifying lenses on a stand like they sold for 7" TV sets back in the 1950's so the picture looked like it was 10" - if you sat directly in front of it.

[Elecraft] Another P3 Arrival
P3-K ordered/invoiced on July 16, 2010. Arrived and "in-work" at 1930PDT August 31, 2010. P3 S/N 344. Will live with K3 S/N 4497. Let the fun begin. The K3 is working flawlessly. I love it.

Re: [Elecraft] P2 anyone ??
Having just built a P3 kit this afternoon, in about 1.5 hours and another hour "playing" with it, I am now an "expert" (I know Alan is the real expert). No, this one is not mine, but it was for a friend - I am still using the "cheapie" softrock/Z1 and PowerSDR solution. The P3 build is simplicity itself, thanks to the marvelous instructions (Thanks Ron). The P3 box has plenty of open space (I wonder what Wayne will fill it with), and the additional holes on the rear panel (covered by the plastic "dust shield") give me cause to anticipate other wondrous things that might be supported by this box in the furure. I can say that the P3 display far exceeds the capability offered by PowerSDR in that the span and the amplitude and baseline can be changed very easily to allow inspection of an individual signal or the entire 200 kHz portion of any band, and no computer (with all its complications) required. The display is much more crisp than that afforded by PowerSDR/IF even though the display overall size is smaller. Onward and upward for the Elecraft design team. 73, Don W3FPR On 8/31/2010 10:09 PM, Alan Bloom wrote: > (Giggle...) I think it actually would be possible to home-brew your own > P2.

Re: [Elecraft] P2 anyone ??
I took one of Jack Smith's Z90's and repackaged it in a box that's the same width and depth as the K2, is tall enough for the Z90 display, and is constructed the same way as the K2. I also added an internal USB interface. I'm traveling right now, or I'd send put up a photo or two. It's also being flaky- it runs for a while, then the display goes wonky. I've just not gotten to it (both my K2's have bad headphone jacks, too). 73, doug On 01-Sep-10 01:18, able2...@aol.com wrote: > I for one would really like to see a panadaptor for the K2.

[Elecraft] Microham MKII
What has changed? Because of work, I was off the air until I went down to Little Cayman (ZF2JG) I tested out the K3 up here before I left but did not bother to hook up the Microham MKII in that testing. Big mistake. When I got down there, the K3 would not interface with the MKII at 38400 bps. When I got home I noticed a new setting of K3 (patched) and it appears to work at 4800bps but not above that level. I guess something has changed.
