Re: [Elecraft] SDR_Sound_Cards
I'm running a 0204 with NaP3 on The Release to Manufacturing build of Windows 8. 64 bit, it all works great as expected They don't have the Windows 0204 drivers on the website because it comes with them in the box.(I found it curious why they don't have them on the website for the 0204) I also have a 0202 that works find in Windows 7 64 bit, you can download these drivers on the creative website and to be honest, I think they are the same drivers that come in the box with the 0204. All running with an LP-PAN II of course. It by far has exceeded my expectations. LP-Bridge + LP-PAN II + K3 + E-MU 0204 + Windows 7/8... solid and reliable. With N1MM or DxLab... with NaP3 cranking away. Very little CPU usage on a nice i5 setup with a $120 AMD discrete video card. If you want a plug and play toaster, get the P3... if you want total flexibility with a smooth as silk sizable window with a great mouse interface, go with the Creative E-MU 0204 and the LP-PAN II. If you are trying to run this on some old dog single or dual core setup with a 13 year old OS like XP... well then good luck. de NG7M KQ8M wrote I'm sorry but it is true. I have 2 0204's and neither work for crap on Win 7. I have been on Creative's forums and read all of the big audiophile's that used the 0204 on XP but cannot get it to work worth dung on Vista or Win 7. I have tried. Go to Creative's website and see if you can download drivers for an 0204 for ANY Windows platform! -- M.

[Elecraft] P3 Utility and Mountain Lion problem
I tried this morning to install the new firmware for the P3 (beta SVGA 0105BEATA.ZIP) but I was not able to run the P3 utility (1.12.4.26). I use a MAC and the problem is probably the new OSX (mountain lion) I installed few weeks ago. K3 utility is running fine. There was a threat on the reflector on this subject but without solution and no mention if the OS was Lion or the mountain lion. Any suggestion or help ?

[Elecraft] KX3 CW Key Sluggish Response
My KX3 is behaving unusually this morning, so much so that I cannot use it for CW. The first character is beginning, I don't know, about ½ a second delayed from when I press the paddle (both dit or dah), causing just enough confusion in my brain to obviate my sending readable cw. It's not the paddle itself; the behavior is consistent even using my Begali outboard key. Adjusting the QSK delay makes no difference (really didn't expect it to as that delay is the 'hang time', not the start time). Any suggestions would be welcomed and appreciated.

Re: [Elecraft] SDR_Sound_Cards
Tony, You are correct. However, I think you missed my point. The discussion has been concern over using cards that are capable of a 192KHz sample rate. My point was, maybe stated badly, was that shouldn't be a consideration as Elecraft was saying you really should stay at 48KHz, but 96KHz would be just OK . I was not trying to get into a Nyquist discussion. I think the concern has been the ability to see the entire spectrum of the ham band being used. And, I was trying to say that you will see it, just 48KHz at a time, software controlled. If the recommendation is to steer away from the 192KHz. bandwidth, consideration of a 192KHz. capable card is kinda mute. Go for a card that has high linearity and low internal noise, and some of those do not go to 192KHz. 73, Barry K3NDM - Original Message - From: Tony Estep estept...@gmail.com To: elecraft@mailman.qth.net Sent: Friday, August 31, 2012 3:29:22 PM Subject: Re: [Elecraft] SDR_Sound_Cards On Fri, Aug 31, 2012 at 11:42 AM, Barry LaZar k3...@comcast.net wrote: if you opt to use NaP3 and set it so that what you are tuned to is in the center of the display, you will always see the +/- 24KHz == The amount you see is selectable.

Joe... Good thought. Along the way to getting LP-Pan working, I had forgotten about the secondary CAT port in Router. I tried that, and as you said, it works fine. One small point is the need to load Router in the standard environment. Without it there's no control with NaP3.

Re: [Elecraft] OT: FCC Exams
I can answer that one, mostly, and only because I asked someone about it ages ago. Hard to believe that was at least 15 years ago. So, before Eric yells end the thread, as he will undoubtedly foo soon... Anyway, all the 1X2 G calls were issued pre-WW2, and then they started with the G2's, but didn't complete the series. Full licensees got G3, G4, and then G0. Full no code licenses starting in 1968, I think, got G6, G7, and G8. Not sure about G1, but G5 three-letter suffixes were issued to reciprocal licenses, that is, until people could just sign W1XYZ/G0 or whatever (switching to the G0/W1XYZ format in the mid-90's.) Unlike calls issued here, the prefix, GM, GI, etc., denotes where in the UK the call is being used. Thus, G0XYZ, if he goes to Wales, becomes GW0XYZ. No muss, no fuss. Oh, and GB prefixes are special calls. Like special events, repeaters, probably club stations as well. When the G0 series finished up, they moved on to the M series for full licenses. M3 and M6 are reserved for the fairly recent Foundation class license. 2E licenses are the old UK novice. Which I believe is now intermediate license. 50 watts. I think I'm right about that, but I might not be full on.

Re: [Elecraft] KX3 Speaker Screw size
Thanks Ron for the advice. We found a suitable way to mount the rig. My guess is that we will need to revisit this down the road. We are about 35% complete with the install.

[Elecraft] [K2] KPA100 Troubleshooting - SWR high on low bands, Loss of power control
My KPA100 has been giving good service for nine and a half years. Back in July, it was giving me an INFO 080 issue, which I tracked down to a defective U6 - EL5146C on the KPA100. I've successfully replaced this chip, and now the KPA100 is responding. Because of the part replacements, I have gone through the KPA100 alignment steps. The first indication of a problem was during the SWR Bridge Null Adjustment. While I could get a clear null, the display never showed anything less than 1.1 SWR on 40m. Next the Power Calibration. This went fine as well, but when I checked the SWR on all the bands, I received a 1.8 SWR on 80m, and 2.6 on 160m. The highest bands gave a 1.0 indication, but most of the others were 1.1, just like 40m. I double-checked my dummy load with my external watt meter. It appears they are 1.0 on all bands. Doing some full-power tests: * 40m - K2 indicates about 70 watts (7 bars), but the external watt meter shows 100 watts * 80/160m - K2 indicates about 50 watts (5 bars), and sometimes I get a Hi Cur warning. The external watt meter shows 100 watts, or perhaps a little more. Something is obviously wrong with the power measurement circuits here. Any suggestions as to what I should do to troubleshoot this further? __ 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 CW Key Sluggish Response
Well, I just figured out the 'problem' with the delayed response of keying the KX3 rig I'm LOL'ing.

[Elecraft] KX3 build question
I am in the final assembly of my Kx3, And it appears that the KXFL3 is keeping that corner of the case from completely closing (by just a little bit)- as in both sides bottoming out, where the thumb screw comes in contact with the to chassis. . With the FL3 removed, it closes completely. I have trimmed the cutout fingers from the edge of the fl3. It does seem to close well enough, but just not all the way. Is this a concern, or am I good to go?

[Elecraft] KX3 - Balun
I have had some parts around for a while now that I intended to build a balun out of. I finally got around to working on one over the past week or so (I started last Sunday night and did all the rest of it this evening HI). My idea was to make a 1:1 balun that fit right on the rig for using the internal tuner with a doublet, or any other balaned line fed antenna. Below are links to pictures of what I came up with. http://s118.photobucket.com/albums/o117/KC8QVO/QRP%20Projects%20and%20Stuff/?action=viewcurrent=IMG_9333.jpg http://s118.photobucket.com/albums/o117/KC8QVO/QRP%20Projects%20and%20Stuff/?action=viewcurrent=IMG_9333.jpg http://s118.photobucket.com/albums/o117/KC8QVO/QRP%20Projects%20and%20Stuff/?action=viewcurrent=IMG_9334.jpg http://s118.photobucket.com/albums/o117/KC8QVO/QRP%20Projects%20and%20Stuff/?action=viewcurrent=IMG_9334.jpg I used parallel runs of about 15-17 of 18 gauge magnet wire, two stacked FT-82-43 cores (Amidon), 3/4 stainless screws, two nuts, two flat washers, two lock washers, two wing nuts, about 1 of 18g stranded speaker wire (lead-in to the BNC connector), BNC connector for RG-58 coax, two small ring terminals minus the plastic sleeve, and a small enclosure box from Mouser. The BNC connector is bolted to the enclosure. It is a crimp style. I soldered the center pin then used the rear nut/bolt part passed through the wall of the enclosure as the mount for the plug. It is a pretty slick idea and quite rigid. There are 10 wraps of the magnet wire around the cores. Wrapping the stacked cores was a chore. I did not use anything to bond the cores together first (no tape or anything, just the wire). Once I had about 3-4 wraps on there it stiffened up but it was a trick. One addition I may make to the balun is a piece of plastic between the turns and the ring terminal crimps along the sides. I would imagine having the terminals that close (right against) the windings is not a good idea. I have another idea for a balun that is identically designed with a chassis mount BNC connector (single hole, not the 2 or 4 hole flanges) for use as a dipole feed point. I have a T80-2 Amidon core wound up already, again 10 windings of the 18g magnet wire. This fit too tight inside the small square enclosure but I have some that are rectangular and will have about twice the vertical space. This will let me space out the ring terminals at the top as well as have plenty of space for wiring the bulkhead BNC connector on the bottom.

Re: [Elecraft] KX3 CW Key Sluggish Response
Thanks for telling us about this feature. I remember one of the jokes we played on announcers at the collage radio stations. We would set up a short delay with a 3 head tape recorder and patch it into the audio line when the record stopped. The DJ would then hear his voice delayed by about 1/2 second. The universal reaction was to tear off the headphones, finish speaking, start a new record, and come looking for us.

Re: [Elecraft] [K2] KPA100 Troubleshooting - SWR high on low bands, Loss of power control
Bill, I am puzzled why a bad EL5146C would cause an INFO 080 problem. INFO 080 normally is the inability of the MCU to properly communicate with another firmware processor. While it is entirely possible that the EL5146C was dragging down the output of the +5v regulator and causing the KPA100 firmware IC to fault, but I cannot tell from this distance. As for your wattmeter problems, I suspect that the diodes D16 and D17 may be half bad. Yes, that is rare, but possible - they have been damaged enough to change their characteristics but not make them either open or shorted. I would recommend arbitrarily replacing them and then try the wattmeter calibration again. For initial settings, adjust R26 to produce 43k ohms to ground as measured at U5 pin 5, and R27 to give 43k ohms as measured at U5 pin 3. After that do the null adjustment and see what happens. I just returned from the Shelby, NC hamfest - a good time was had by all even though it was quite hot and humid. 73, Don W3FPR On 9/1/2012 4:31 PM, Bill Coleman wrote: My KPA100 has been giving good service for nine and a half years. Back in July, it was giving me an INFO 080 issue, which I tracked down to a defective U6 - EL5146C on the KPA100. I've successfully replaced this chip, and now the KPA100 is responding. Because of the part replacements, I have gone through the KPA100 alignment steps. The first indication of a problem was during the SWR Bridge Null Adjustment. While I could get a clear null, the display never showed anything less than 1.1 SWR on 40m. Next the Power Calibration. This went fine as well, but when I checked the SWR on all the bands, I received a 1.8 SWR on 80m, and 2.6 on 160m. The highest bands gave a 1.0 indication, but most of the others were 1.1, just like 40m. I double-checked my dummy load with my external watt meter. It appears they are 1.0 on all bands. Doing some full-power tests: * 40m - K2 indicates about 70 watts (7 bars), but the external watt meter shows 100 watts * 80/160m - K2 indicates about 50 watts (5 bars), and sometimes I get a Hi Cur warning. The external watt meter shows 100 watts, or perhaps a little more. Something is obviously wrong with the power measurement circuits here. Any suggestions as to what I should do to troubleshoot this further? __ 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 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] KX3 Utility and iPad
We are about halfway through my install of the KX3 in my 97 Silverado and it is going well so far. We probably have another two days (16-20 hours) plus worth of work to go before we are done with the install. We installed the Rammount for the iPad and the KX3 and it looks epic. The amps are mounted and the electrical and antenna installation is in progress. Still need to pull wire from engine and new breaker and solenoid to bed and husky toolbox to the deep cycle Optima battery and the amplifiers. The Hi Q 4/80 RT is still in transit so that install will wait until next week. In terms of control theough the ipad I am planning to use the iSDR software with a simple logging program (MacLogger possibly) and upload later when at my home QTH. I was doing research on IPad ham apps and am looking for other control software options. Even minimalistic control software besides iSDR. I was also curious if the KX3 utility software and terminal will work on the iPad. Also any perspective on new software developments for the iPad and ham radio software especially the KX3 would be super appreciated.

Re: [Elecraft] PsychoAcoustics and Delay
I don't know of any studies relating to delays and our ability to send CW. Empirically the issue starts to become noticeable when the delay is more than an element (dit/dah) and certainly becomes critical when the delay is a substantial part of a letter. Just like the soloist and the National Anthem, the solution is to provide undelayed sidetone from the keyer rather than an off air monitor or RF derived sidetone. BTW, another place acoustic/DSP delays have become an issue is with live TV news. In the old days we used off-air analog signals or analog cell-phones for IFB (interruptable fold back) but with the advent of digital cellular systems and digital broadcasting, the delays are well in excess of the magical 150 - 200 ms threshold. For TV applications, the solution is to provide mix minus - that is the program feed *without* the reporter's own voice - so the reporter can interact normally with other participants. 73, ...

Re: [Elecraft] PsychoAcoustics and Delay
Hi George, Great to hear from you. Henry was mondo cool. A google search will turn up lots of interesting stuff. For the last couple of decades of his life he was the chief scientist for our country, founding director of the Smithsonian. The entire US government closed down the day he died and again for his funeral. I learned a lot about him when I did the research to cite him has a reference for an AES paper I was writing on stereo soud reinforcement around 2000, and invited an historian who concentrated on his work to speak to our AES section soon after. One of the things he was asked to weigh in on had to do with the physics of propagation of sound from foghorns. Big deal back then, there were multiple theories advanced, instrumentation to resolve the issue would not exist for at least 100 years, and he publicly put his money on the right horse. His work on the perception of sound and delay that formed the basis of stereo was published in 1850, and it was quite solid. There are multiple volumes of his scientific writing. I found them in the Northwestern University library. 73, Jim K9YC On 9/1/2012 9:38 PM, gdaug...@stanford.edu wrote: Hi Jim, One of the earliest scientists was Joseph Henry, inventor of voltmeters and motors, whose name is on the unit of inductance.
