[Elecraft] K3 firmware update failure
Sort of related to your problem... Last week I bought the PX3 for my KX3. The PX3 required a much later firmware installed in the KX3 than was in it (I had not kept it current; if it ain't broke, don't fix it mentality). So, I downloaded the current KX3 utility, got the latest firmware and started the process to load the new files to the KX3. Nothing. Couldn't get the Windows laptop pc running Vista to talk to the KX3. I have three KXUSB cables. Tried them all. Nothing. Went back to the Elecraft website and downloaded the FTDI chipset driver. Still nothing. This is the same computer I have been using all along with all of my Elecraft equipment and it worked last time I tried. Contacted tech support at Elecraft, followed all their suggestions and still no joy. So since the laptop was getting a few years on it and lacked many of the modern features (no touch screen, etc) I went to my local big box electronics store and bought the least expensive laptop (out the door for a little over $300) they had runni ng the most up-to-date Windows operating system. Installed the utility and files on it then uploaded the new firmware to the KX3 first try. I had needed a new laptop anyway that was dedicated to the ham shack so I solved two problems with one purchase. Maybe you have a friend willing to let you try his computer? Or maybe you are in need of a new laptop? I sure like the PX3! __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] K3 power set
I switch between low power with JT65/JT9 and regular use with my KPA500 for CW. I set up a JT65 macro to switch antennas and change my power down to 20 watts as well as put the K3 into DATA mode. I have a second macro to switch back to regular CW mode, other the antenna and 100 watts. I also have the PWR SET to PER-BAND so as not to overdrive my KPA500 (typically it needs 20-25 watts). The PWR SET has two sets of PER-BAND power levels, one for barefoot level (100 watts in my case) and one for the KPA500 (20-25 watts). Works perfect (yes, I am using the cable between the K3 and KPA500), except when switching back from JT65/JT9 mode. BOTH power levels on that particular band get reset to 100 watts. More than once I panicked when I had red lights and the OVERDRIVE message. But, thank you Elecraft for building very good protection into the KPA500, so no ill effects other than my heart rate raising too quickly. The easy solution is to set power control on switching back to CW mode to a much lower power, say 20 watts. And I have done that. But my question is: is there another way to do what I am doing without resetting the 2 per-band power levels? Thanks.. Jim Leder ...

[Elecraft] K3 and HRD: MAC using VMWare + HRD, no waterfall display
I'm trying to get my new K3 on the digital modes using HRD. On the advice from the good folks on this list, I purchased a Tascam US122 MK II. No regrets there, it's a great unit for the price. My setup has HRD running under VMWare on a Macbook Pro/Yosemite. I'm running latest Windows 8.1 with HRD in the VM. I am confident in the physical setup, as I can use fldigi natively on the MAC successfully. But, HRD displays no waterfall at all. Sometimes, I see RX activity on the built-in software sound card monitor within HRD, and HRD can in fact see my Tascam under sound card setup, but nothing i've tried will actually make it work. The waterfall display is always dark, indicating no incoming audio, even though the LEDs on the Tascam, indicate activity. Has anyone had success using this setup? Any recommendations for a path to success? Should i try another sound interface? (Don't have one presently.) Sould I ditch the MAC and buy a windows box (ouch)?

Re: [Elecraft] K2 Illumination?
Frank, The problem has to do with the light conductivity of the LCD diffuser. It is possible that one of the thin plastic sheets on the diffuser that should not have been removed was actually removed during assembly. The only correction is to replace the diffuser. Unfortunately, it is below the LCD and inside its pins. While removing the LCD with its many pins may be possible, it is not practical. If you want to change the diffuser, you will have to remove the LCD. The best (safest) method is to cut the LCD pins near the LCD body and remove the pins one at a time. Then remove the diffuser. Replace both the diffuser and the LCD. If that is too much pain, you will have to live with it as-is. 73, Don W3FPR On 3/30/2015 12:05 PM, Frank Krozel wrote: Folks, I have two of these one is S/N 906 and the other one is 57xx.

Re: [Elecraft] K3 and HRD: MAC using VMWare + HRD, no waterfall display
I have the Tascam US122mkII running on MacOS 10.7.5 on a MacBook Pro. I'm running it on MacOS rather than Windows. It works, but I occasionally have to reboot the Mac to get the driver to properly connect with the Tascam. When it's not working, it looks like everything is connected properly, but there is a lot of noise and distortion in the signal. My problem frequently shows up if the Tascam is plugged in to the USB connection after the Mac is booted. Note that I haven't spent enough time chasing this issue to be really sure what is happening. 73 Bill AE6JV On 3/30/15 at 8:45 AM, challi...@gmail.com (Chris Hallinan) wrote: I'm trying to get my new K3 on the digital modes using HRD.

I was NOT responding to the original poster. I was responding to the second commenter, who said that he needed a schematic because his NEW KPA500 had failed. My point was that rather than risk further damaging a NEW, still under warranty KPA500, why not simply let Elecraft fix it.

Re: [Elecraft] K3 firmware update failure
The first cardinal rule when a peripheral or device quits working under a Windows OS: check/reinstall the driver and look for anything that might have changed in software. I cringe at the number of modems, sound cards, etc. which have been thrown in the trash by people who didn't understand the process. My [insert device here] quit working. I went to Best Buy etc. and bought a new one. It works so the old one must have been bad. By installing the new device a new device driver was installed DUUHHH!! There is a good chance the driver or something in the OS was corrupted or incompatable, rendering the original device useless. (The classic related to this was a few years ago when some users reported receiving blue screens after a windows update was released. Investigation proved it to be an incompatability of the update with a certain piece of -- malware!) 73, Al On Mon March 30 2015 11:01:53 am Tony Estep wrote: On Mon, Mar 30, 2015 at 8:02 AM, GDR k...@charter.net wrote: ...This is the same computer I have been using all along with all of my Elecraft equipment and it worked last time,,, I had a Windows 7 laptop that ran my station perfectly for years.

Re: [Elecraft] K3 and HRD: MAC using VMWare + HRD, no waterfall display
I'm not familiar with VMWare, but under Parallels, youhave to make sure that the various devices, e.g., theserial lines and/or audio codecs, that you need for HRDhave been assigned to Parallels (and Windows) so thatWindows can legally access them. It sounds like you've gotthat much at least partially configured. I'm assuming you have HRD 6.2.9.354 (which I have) or later. Does the HRD Rig Control come up properly, and does itfollow your VFO when you turn the main knob on your K3? On DM780, go into Program Options - Soundcard anddouble-check that it's looking at the audio device you thinkit should be looking at. (I use a SignaLink USB, so it showsup as USB Audio Codec; YMMV, and yes, I know better, but...). Also under Program Options, you might want to investigateSoundcard Calibration. I'm not convinced that that alonewould fix your problem, but it might give you a better idea asto which tree to bark up next. On the main DM780 window, click on Soundcard, which shouldbring up a couple of vertically oriented bar graphs - see ifthe receive one is behaving appropriately; you may need toadjust an input level on your Tascam or other device if it'sin Overload or barely bumping the thermometer. BTW, thereare some helpful tips in the info area in the lower right-handcorner of the Soundcard window. You might also need to go into the OS X settings to double-checkthat it isn't (also) trying to grab the Tascam and/or the K3's serial line,even if VMWare and Windows think they own them. I haven't looked at the HRD forum lately, but you might take a lookover there just in case someone with this particular configurationhas encountered this problem before.

Re: [Elecraft] RTTY K3 Help
MMTTY [free] will provide stand-alone AFSK RTTY with your current setup. N1MM will also use the MMTTY engine for you in a contest or when calling DX in a pileup. Download MMTTY to someplace on your computer, and then in the N1MM setup, tell it where to find MMTTY. Then, in N1MM when you open the digital interface window, the MMTTY window will also come up. MMTTY is a tad complex and obscure, but the good news is that it works well right out of the box, so you can ignore most of the options. Never understood the infatuation with direct FSK, but to each his own. For RTTY, select AFSK-A. You can select audio frequency with the K3 PITCH control, there are 4 choices I believe, mine is at 915 Hz [lowest]. Be sure MMTTY is also set at 915. Recent firmware editions include a filter in AFSK-A which really narrows your signal. AFSK-A is LSB. Put the K3 in TX TEST, go to transmit, and adjust the MIC GAIN for 4 solid bars ALC with the 5th flickering. Then go to TX NORM and set the desired power. You can't control the power on a K3 with the MIC GAIN. You won't find many casual QSO's on RTTY. AFSK PSK31 is actually redundant. :-) 73, Fred K6DGW - Northern California Contest Club - CU in the 50th Running of the Cal QSO Party 3-4 Oct 2015 - www.cqp.org On 3/30/2015 11:56 AM, Joe Moffatt wrote: I think I actually misworded things.

Re: [Elecraft] RTTY K3 Help
AFSK PSK31? There's an oxymoron ;) If you have PSK31 working, you can do AFSK RTTY with the same hardware configuration, but use the AFSK A sub-mode, instead of DATA A. If you want to do FSK instead (FSK D sub-mode), you'll need a hardware interface of some sort (could be as simple as a couple of transistors and resistors to level-convert between a RS232 port and the K3's PTT and FSK inputs. Whether or not FSK is better than AFSK is somewhat of a religious debate.. 73, ~iain / N6ML On Mon, Mar 30, 2015 at 11:56 AM, Joe Moffatt j...@selectconnect.net wrote: I think I actually misworded things.

Re: [Elecraft] KX3: SDR Software Solution!

Re: [Elecraft] K3 and HRD: MAC using VMWare + HRD, no waterfall display
Thanks for all the helpful tips and information. Through more testing, it appears it's not DM-780 problem at all, but more likely a bug in the VMWare USB stack. I can get PC sounds to play through the device, but as soon as I change anything at all, the sounds stop working and nothing I can do except unplug and replug the device (virtually, using the VMWare Fusion Disconnect/Connect menu items) will make it work again. So, I will go chase down that avenue. I'm a paying customer of VMWare, so maybe it's time to submit a support request! Thanks again, Chris K1AY On Mon, Mar 30, 2015 at 1:27 PM, Bayard Coolidge, N1HO n...@yahoo.com wrote: I'm not familiar with VMWare, but under Parallels, you have to make sure that the various devices, e.g., the serial lines and/or audio codecs, that you need for HRD have been assigned to Parallels (and Windows) so that Windows can legally access them. It sounds like you've got that much at least partially configured. I'm assuming you have HRD 6.2.9.354 (which I have) or later. Does the HRD Rig Control come up properly, and does it follow your VFO when you turn the main knob on your K3? On DM780, go into Program Options - Soundcard and double-check that it's looking at the audio device you think it should be looking at. (I use a SignaLink USB, so it shows up as USB Audio Codec; YMMV, and yes, I know better, but...). Also under Program Options, you might want to investigate Soundcard Calibration. I'm not convinced that that alone would fix your problem, but it might give you a better idea as to which tree to bark up next. On the main DM780 window, click on Soundcard, which should bring up a couple of vertically oriented bar graphs - see if the receive one is behaving appropriately; you may need to adjust an input level on your Tascam or other device if it's in Overload or barely bumping the thermometer. BTW, there are some helpful tips in the info area in the lower right-hand corner of the Soundcard window. You might also need to go into the OS X settings to double-check that it isn't (also) trying to grab the Tascam and/or the K3's serial line, even if VMWare and Windows think they own them. I haven't looked at the HRD forum lately, but you might take a look over there just in case someone with this particular configuration has encountered this problem before.

Re: [Elecraft] 50 Ohm Load - source?
Yes, you are. Dummy loads are not fun, like nice radios. When I built a Heathkit HW100, 45 years ago, I needed a dummy load to align the transmitter section. Not having one, and having just spent all my discretionary funds on the radio, I used a pencil lead to make a resistor element. I had to experiment with different drafting pencils to find the correct resistance. I carefully removed the wood with a razor blade, and attached clip leads at the points that gave me 50 ohms. I dunked the result in a container of motor oil (probably not the best choice), and finished the alignment. It worked well and was a one shot deal. Later, following instructions in a ham radio magazine, I built a dummy load using two copper disks and 10 resistors. This was also installed in a quart can filled with oil of some kind. I put the dummy load under my shack and ran coax up to my rigs. Also worked well. Now, I use an Elecraft 20 watt load, and have used it for short periods of time at higher power to make quick measurements. This included the alignment work on my K3/100. 73, Rick Dettinger K7MW On Mar 30, 2015, at 2:43 PM, Dave Baxter wrote: I often wonder about people who will buy expensive (but excellent) radio's, then baulk at spending a few bucks, quid's or ?, on basic test kit like a half decent dummy load!

I have a couple other 20W homebrew loads around here too...can never find one when I need it though...the 100RFL sits in a handsome cabinet on my bench where is it handy and usable all the time. No sir...can't beat a good dummy load. On 3/30/2015 7:17 PM, Rick Dettinger wrote: Yes, you are. Dummy loads are not fun, like nice radios. When I built a Heathkit HW100, 45 years ago, I needed a dummy load to align the transmitter section. Not having one, and having just spent all my discretionary funds on the radio, I used a pencil lead to make a resistor element. I had to experiment with different drafting pencils to find the correct resistance. I carefully removed the wood with a razor blade, and attached clip leads at the points that gave me 50 ohms. I dunked the result in a container of motor oil (probably not the best choice), and finished the alignment. It worked well and was a one shot deal. Later, following instructions in a ham radio magazine, I built a dummy load using two copper disks and 10 resistors. This was also installed in a quart can filled with oil of some kind. I put the dummy load under my shack and ran coax up to my rigs. Also worked well. Now, I use an Elecraft 20 watt load, and have used it for short periods of time at higher power to make quick measurements. This included the alignment work on my K3/100. 73, Rick Dettinger K7MW On Mar 30, 2015, at 2:43 PM, Dave Baxter wrote: I often wonder about people who will buy expensive (but excellent) radio's, then baulk at spending a few bucks, quid's or ?, on basic test kit like a half decent dummy load!

Re: [Elecraft] Is there a K4 on the horizon?
No guarantees, but I understand that Elecraft may be making a new product announcement at IDXC in Visalia at the new product showcase on April 18th. I don't guarantee to be there, as this forum is scheduled for 0830-0930L. :-) Last time I got excited about the announcement of a new product, it was at the Dayton Hamvention, 2013. Turned out that Ten-Tec introduced their new programmable QRP radio. Did nothing for me. Then again, just when I thought I owned everything that I needed from Elecraft, Eric motioned me over at IDXC 2014 and showed me the new PX3. Of course, I now own one of those, as well. 73 de Jim - AD6CW On 3/30/2015 1:14 PM, Fred Serota wrote: Is there a K4 or 1500 watt amplifier on the horizon?

Re: [Elecraft] Is there a K4 on the horizon?
Last year at IDXC, I decided to take a chance during a forum that Eric was presenting, to put in a good word for an all-mode VHF/UHF transceiver. I brought up the point that Elecraft already sells transverters for 2m/222 MHz/432 MHz, so they have the technology. Unfortunately, it comes down to whether the product would have sufficient appeal to justify the RD costs. Well, I tried! 73 de Jim - AD6CW On 3/30/2015 5:30 PM, Milverton M.

[Elecraft] 50 Ohm Load - source?
It appears some think just because you are interested in building a new dummy load that you don't have one. Interesting how some can build an entirely wrong building out of wrong assumptions. I have a 300w and a 1500w dry dummy loads and a Cantenna that all work just fine but just thought this 100w one would be fun to build and the price is right. Can't have too many toys. I have two complete VHF go kits each with digital capability and an HF go kit as well all with separate components from my base station. We sometimes have exercises and use dummy loads instead of antennas in tabletop training so can use a couple of extra dummy loads at times. Works very well with one in the go kits as well as one at the base. 73, Jim KG0KP __ 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 Message delivered to arch...@mail-archive.com

A dummy load or SWR bridge that's out of spec can cause us to make bad decisions about matching in our system, or to mis-calibrate it.

[Elecraft] 50 Ohm Load - source?
Very well said, don. If ham does not need a new dummy load, there are a lot nice ones available in the used market at a very reasonable price. Nowadays, frequency counter, RF watt meter and DMM are all available at a much affordable price. Even a temperature controlled soldering iron is not expensive. All those items were totally out of the question when I started my hobby at the age of 12. Let us enjoy our hobby in a much affordable way now. 73 Johnny VR2XMC 寄件人︰ Don Wilhelm w3...@embarqmail.com 收件人︰ elecraft@mailman.qth.net 傳送日期︰ 2015年03月31日 (週二) 12:06 PM 主題︰ Re: [Elecraft] 50 Ohm Load - source? I think that attitude spells the difference between appliance operators and those who are willing to check out, and otherwise examine their ham gear. How many transceiver problems turn out to be problems with the antenna system? The number is larger than many are willing to admit. In the long past, every ham had at least a few test tools - dummy load (even if it was a light bulb), and means of measuring RF and SWR (even if it was a pair of #47 lightbulbs on a piece of 300 ohm twinlead) - and that gear was used to determine if the transmitter was capable of producing power and if the antenna system was capable of accepting the RF power. There were times when precise and accurate measurement gear was outside the budget of most hams, so we used substitute methods that gave us some indication that our transmitters and antennas were performing OK. Today, reasonably good dummy loads and wattmeters are well within the budget of the typical ham. When we are willing to spend $1000 or more on a transceiver, I find it foolish economy to decline to spend $100 for a few pieces of test gear to assure ourselves that that $1000+ transceiver is running properly. It seems some hams would rather 'send it back to the factory for a checkout' than to make some simple measurements in the shack - the cost of that trip to the factory will exceed the cost of the equipment required to do simple testing of the equipment in place. It does seem like false 'economy' to me, but I know there are some who will do just that. And - when the transceiver returns with no trouble found because the problem was actually in the antenna system, that is not helpful. The cause of the problem could have been identified if a dummy load and a wattmeter had been available and willing to be used for some simple tests. The precision of the dummy load and wattmeter need not be extreme for tests of this sort - even gear with a 20% or greater error can give clues to the cause of failure in cases like that. Yes, I now have precision dummy loads and wattmeters whose calibration is NIST tracable, but I use those for precision measurements. To do a 'sanity check' of where the problem may be does not require anything near that precision or accuracy. As I have stated in the past, every hamshack should have a dummy load capable of handling the maximum output of that station. It need not be exactly 50 ohms non-reactive (unless it is being used for calibration), but it should be a part of the diagnostic tools available in every hamshack. 73, Don W3FPR On 3/30/2015 5:43 PM, Dave Baxter wrote: I often wonder about people who will buy expensive (but excellent) radio's, then baulk at spending a few bucks, quid's or ?, on basic test kit like a half decent dummy load!

And - when the transceiver returns with no trouble found because the problem was actually in the antenna system, that is not helpful. The cause of the problem could have been identified if a dummy load and a wattmeter had been available and willing to be used for some simple tests. The precision of the dummy load and wattmeter need not be extreme for tests of this sort - even gear with a 20% or greater error can give clues to the cause of failure in cases like that. Yes, I now have precision dummy loads and wattmeters whose calibration is NIST tracable, but I use those for precision measurements. To do a 'sanity check' of where the problem may be does not require anything near that precision or accuracy. As I have stated in the past, every hamshack should have a dummy load capable of handling the maximum output of that station. It need not be exactly 50 ohms non-reactive (unless it is being used for calibration), but it should be a part of the diagnostic tools available in every hamshack. 73, Don W3FPR On 3/30/2015 5:43 PM, Dave Baxter wrote: I often wonder about people who will buy expensive (but excellent) radio's, then baulk at spending a few bucks, quid's or ?, on basic test kit like a half decent dummy load!

Re: [Elecraft] K3 firmware update failure

Then one day it would not send CW to my K3. I tried new cables, new drivers, new CW software, etc. etc. I figured that the USB hardware had failed. But one of my kids is an MSEE in charge of a huge network of servers and clients, and he said that it was probably a Windows update that had hosed something in the USB control chain. So I upgraded to Win 8.1, and sure enough, everything came back to life. So maybe the same thing happened in your case -- you had a combination of hardware and drivers that somehow wouldn't play with some update that came since the last time you tried it. Anyway, you're up and running, which is the important thing. 73, Tony KT0NY __ 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 Message delivered to arch...@mail-archive.com
[Elecraft] K2 Illumination?
Folks, I have two of these one is S/N 906 and the other one is 57xx. The light on 906 is bright on both ends and the 57xx is about the same level across the display. Without tearing apart both… anyone know what I can change on 906 to make it the same level of brightness across the panel? If this will allow me to show you .. here they are.. http://electronicinstrument.com/k2disp.jpg http://electronicinstrument.com/k2disp.jpg (Yeah, bored.. ) KG9H Sincerely, Frank Krozel t: 1-630-924-1600 fr...@electronicinstrument.com mailto:fr...@electronicinstrument.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 Message delivered to arch...@mail-archive.com
