Re: [Elecraft] Wizkers:Radio KX3/KXPA100/PX3 utility and rig controller
Awesome! I've been puzzled by the lack of ham radio Chrome apps, and was toying with the idea of writing something simple, like a clone of DroidPSK. Wizkers is vastly better than anything I could have written. Seems like Wizkers would also provide a framework for an cross-platform USB antenna analyzer; basically this hardware with a Wizkers plugin: http://www.hamstack.com/hs_projects/k6bez_antenna_analyzer.pdf I'd love to replace my RigExpert with a USB dongle that works on Chromebook or phone. I look forward playing with Wizkers. Thank you for writing it and open-sourcing it.

Re: [Elecraft] 10 MHz external reference - GPSDO
Guys< TCXO's use temperature compensating components to try to keep frequency stable. They work fairly well if you are at lower frequencies or not multiplying an LO 18 times. Better is the OCXO (which uses a heater inside an insulated "oven" to better keep temperature effects isolated). The EXREF utilizes the better stability of 10-MHz sources to correct the drift of the TCXO. I does that at a fixed interval in between which both TCXO-1 and TCXO-3 will drift. Per Elecraft's specifications on page 8 the TCXO-3 is 5 times more stable than the TCXO-1. I have no idea over what time interval the specs are cited, but most assuredly its more than 4 seconds. I cannot compare the TXCO-1 as I only have the TCXO-3. Both were provided long before the EXREF was designed. I just made a measurement of my K3/10 running 12w for about half a minute 28.200.000 displayed at 28.200.001 at the start. My REF CAL = 49.380.089 before making the 28-MHz test. After several minute long tests the frequency has not budged off 28.200.001. REF CAL now is 49.380.095 so the TCXO-3 has moved +6-Hz over about half an hour. I have been running all afternoon so the K3 was at stable working temp before I made a measurement. Unless you are into frequency measuring or run weak signal modes where hearing a signal is quite difficult, being "on frequency" is very handy. If running CW you probably have bandwidth cranked down to 100-Hz. Digital weak-signal modes tolerate even less error. On 2m-eme using JT65, drifting more than +/- 20 Hz will result in the digital signal failing to decode. Adding the EXREF improves your K3 by five times so perhaps the TCXO-1 is satisfactory for your operating modes. My measurements were really accuracy tests and not stability tests. I did do a 30-minute test at 2m JT65 over a 30-minute period where I would transmit one minuted continuous and then receive one minute. MY K3+2m transverter only drifted upward 7-Hz. It was off frequency by 6-Hz at cold start. K3EXREF with TCXO-3 was used. The transverter uses a heated 116-MHz overtone xtal oscillator inside an insulated can. Does any of this help? Think I beat this to death - OK? 73, Ed - KL7UW http://www.kl7uw.com/K3EXREF.htm Message: 12 Date: Sun, 13 Mar 2016 09:08:10 -0400 From: Don Wilhelm To: Oliver Dr?se , elecraft@mailman.qth.net Subject: Re: [Elecraft] 10 MHz external reference - GPSDO Message-ID: <56e5663a.5080...@embarqmail.com> Content-Type: text/plain; charset=windows-1252; format=flowed I think everyone is ignoring something here. What causes the frequency drift in the first place? It is temperature changes - the designation TCXO signifies Temperature Compensated Xtal Oscillator. It is already compensated for temperature. If the temperature of the TCXO stays the same, the frequency should be stable. There will be some frequency change during warmup after power on, and there will be some frequency change during transmit because the temperature inside the box will increase, and will cool during periods of receive. The difference between the TCXO-1 and the TCXO-3 is one of how much. The TCXO-3 drift will be smaller than the TCXO-1 over the same temperature change. The drift over the 4 or 5 second correction from the external reference will result in a small correction with either TCXO, but it will be smaller with the TCXO-3. Additionally, the frequency drift will be quite small even without the external reference unless there is a rapid and drastic change in temperature at the case of the TCXO. These discussions should include the temperature change during the measurement periods. to complete the picture. 73, Don W3FPR On 3/13/2016 5:27 AM, Oliver Dr?se wrote: > Thanks Ed. > > I don't have a problem understanding how the TCXO's work.

Re: [Elecraft] Adjusting KX3 NR level *after* it's been enabled
That’s what I have to do right now and its insanely annoying because both the OFF and ON operations are long presses. One of the great things about the KX3 is that it has outstanding usability from the front panel knobs and controls. The “adjusting the NR level” problem really kills this. The Win4K3Suite allows tweaking this via a Spin control that appears to execute the remote commands to change the menu settings. Not an ideal solution because each single level change incurs the round-trip delay to execute the remote commands, making the change from say “4” to “7” more time consuming than it needs to be.

Re: [Elecraft] KIO3B
Sometimes there really is no good explanation because people don't use the same hardware, and thus have different drivers installed. They also have different software installed. The machine I'm typing this on is a quad core processor running at 4Ghz with 16 Gigabytes of ram and a pair of SSD's. This thing rips by anybody's standard. It won't run Adobe Flash worth a crap. All three browsers will lock up from time to time. Kill the Flash plugin and it works but there goes my "multimedia experience". So, it could be hardware, it could be USB driver versions, it could be drivers for any of the hardware installed, it could be installed software. It could be Windows itself. Point is the Winkey bypasses all that stuff and is still "one wire compliant" in that it doesn't connect to the radio except the key jack which I assume may already have a paddle hooked up.

I feel there is something wrong here all other commands work fine, when I send a "GET" PC; with the encoder set to 11W I get a return value of "PC011".

[Elecraft] MMTTY Scope & K3s
Something I've noticed that I like very much is the quality of the video you see in the MMTTY scope when using the internal card in the K3s. When I was using a rather decent E-MU 0404 USB sound card for my RTTY needs with the K3, the XY scope showed the two opposing ovals as white bands that were somewhat thick and "sponge-like" in appearance. With the K3s, using the signal generated within the K3, the bands now are very tight, very clearly defined and quite thin. All the artefacts surrounding the ovals are much better defined, there appears to be far less of them and they look like pin points rather than tiny puff balls. It just shows how much better quality the signal is from what the K3s generates than the USB soundcard. The Scope software hasn't changed; same MMTTY but what an immediately observable difference. And yes, decoding is much better too. Kudos to another well done, by the engineers at Elecraft. 73, Gary KA1J __ 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

Re: [Elecraft] KIO3B
Mike, I am using a K3s but the KIO3B is the same for us and I believe the config settings are the same for a K3 with it. I have the USB from the KIO3B going to a powered USB hub with 5 devices total on it. I have the RS232 from the K3s going to a P3 with the CBLP3Y. I was working the Stew Perry contest last night, using N1MM and using its macros to send CW. The only problem I had in sending is in remembering which function key to hit as using a keyboard to send CW is new to me (Well... I did have an Apple II+ back in 1981 that had a board in it for CW/RTTY but nothing keyboard to send CW since then) Someone (here, I believe) kindly helped me with the settings to use with N1MM & the K3 and be sure if you use N1MM, to have in CONFIG, the PTT-KEY set to OFF - RTS. I don't know if any of this will help you but I can say that up to 30 WPM, there is no problem on this end whatsoever. Your solution will likely be easy to resolve once you pin it down. 73, Gary KA1J > An observation. > > Installed a KIO3B in K3 #345, no problems all working either RS232 or > USB or both together for CAT and audio. > > I use Logger32 and prior to installing the KIO3B my 3GHz clock PC > comfortably delivered software CW from within Logger over RS232 without > the need for a Winkey unit. > > I have been running the CAT/audio over USB but apart from checking that > CW keying was working, lights flashing, never listened to it.

Re: [Elecraft] KIO3B
Goes back even further than that, all the way to the semi-automatic bug, in my opinion. We used to put relay circuits on our keys to get reliable, click/bounce free keying of our rigs, due to contact bounce and poor contact in general in the bug's moving parts. I'm going to have to build one of these for my two Vibroplex's in fact to properly key my elecrafts too, because of the occasional 7 to 8ohms that appears when making the Dahs For me, the only really working final solution to using a computer with my rigs has been to unhook it from the rig completely. When I go operate, I have the K2 or K3, a paddle or straight key and a pencil/notebook and that's it. Yeah, I'll never win any contests, but at least I can key the rig. So at the end of the day, I've found, computers and ham rigs ultimately don't mix.

Re: [Elecraft] KIO3B
This seems to be the same ole age old problem of relying on a PC keying CW over a single lead on the RS232 connection or its stand-in (USB). Over and over ad nauseum, literally thousands of times, this has been discussed everywhere since before USB existed. Parallel port keying...if you don't know what a parallel port is, don't feel bad, that's how old this problem is...it first surfaced so long ago I can't remember how far back. Parallel port keying seemed to be far less susceptible, with cleaner code formation. But we all know what happened to parallel ports, if you even know what one is. I have not, in my entire life, heard a satisfying answer as to why the difference. The very large sample size conclusion: Some people can do that and sound perfectly crisp, no matter what. Some will get infrequent odd scattered distortions, that are not enough of a problem to worry about. Others are driven to distraction with distortions sometimes bordering on hilarious. Some computers have spells of it that come and go, seeming to correspond to phases of the moon, alignment of planets, or giraffe mating season. Some now have excellent results with straight, normal RS232, but USB routed functions screw up. Others via USB lines do perfectly well. Others STILL can't use the serial line approach AT ALL. Back in the day, slow CPU speed and limited memory were often associated with the poor performance. SOMETIMES, NOT ALWAYS, upgrades to the CPU and memory would fix it. Many just gave up and went PERMANENTLY to WinKey (way, way cheaper than motherboards and memory) based solutions, myself included. The N1MM integration of WinKey devices is at this point flawless. And the ability now to create tailored PTT, that changes with code speed from a MicroHam box with embedded WinKey, is priceless. There has NEVER, in all this decade of fighting this problem, been a silver bullet solution that fixed the RS232 or USB key line problems. Over the years I have literally seen hundreds of extended email threads about dragged-on investigations by earnest and intelligent ham investigators who never uncovered any solution except throwing bigger and better CPU's at the problem, HOPING for better performance. Some people having the problem, while others with similar or identical equipment having none, simply means nothing. It has always been that way. One swears that he did this or that and the problem went away, and it really did go away when HE did that, he's not lying or deluded. But others try the same solution and nothing changes. Blaming key line over RS232 or USB problems on anything other than poltergeist is just plain unfair. It just could be that one insulted Murphy just one too many times. I understand that people are trying to make cabling go away. Completely understand. Been there, done that, failed. Back to WinKey, permanently. No more wasting time, except my 432nd (or is it 610th, or 326th? I forget) lifetime email on this frustrating problem. I have other poltergeist to work on that have no convenient WinKey solution standing by. 73, and I DO wish you good luck on this one, but don't count on it.

Re: [Elecraft] 10 MHz external reference - GPSDO
I think everyone is ignoring something here. What causes the frequency drift in the first place? It is temperature changes - the designation TCXO signifies Temperature Compensated Xtal Oscillator. It is already compensated for temperature. If the temperature of the TCXO stays the same, the frequency should be stable. There will be some frequency change during warmup after power on, and there will be some frequency change during transmit because the temperature inside the box will increase, and will cool during periods of receive. The difference between the TCXO-1 and the TCXO-3 is one of how much. The TCXO-3 drift will be smaller than the TCXO-1 over the same temperature change. The drift over the 4 or 5 second correction from the external reference will result in a small correction with either TCXO, but it will be smaller with the TCXO-3. Additionally, the frequency drift will be quite small even without the external reference unless there is a rapid and drastic change in temperature at the case of the TCXO. These discussions should include the temperature change during the measurement periods. to complete the picture. 73, Don W3FPR On 3/13/2016 5:27 AM, Oliver Dröse wrote: Thanks Ed.

Re: [Elecraft] 10 MHz external reference - GPSDO
Frequency corrections can only be made in 1Hz steps (at 49.380MHz) and because the higher-specification TCXO should drift more slowly, fewer corrections should be required. But this would only be relevant if someone is using an ultra-narrowband digital mode that is sensitive to sudden small jumps in frequency. 73 from Ian GM3SEK __ 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

Hi Oli, I agree it looks like there is no point in paying for the TCXO-3 if you have a reliable constantly available 10 MHz external reference. Perhaps they recommend the better TCXO as a better fallback if for any reason the external ref is not available, I can't think of any other reason for it. 73 from David GM4JJJ > On 13 Mar 2016, at 09:27, Oliver Dröse wrote: > > Thanks Ed. > > I don't have a problem understanding how the TCXO's work.

Re: [Elecraft] 10 MHz external reference - GPSDO
Thanks Ed. I don't have a problem understanding how the TCXO's work. Maybe I was not clear enough. ;-) Taking your example from below, having only the TCXO-1 it is surely *not* drifting 140 Hz at 28 MHz within the 4 or 5 seconds of the EXREF update cycle (same as the TCXO-3 will not drift by 28 Hz in that time), otherwise the K3 would be a *very* crappy radio. ;-) Think you are missing the time domain here. ;-) So my question still stands: What's the real value of the TCXO-3 over the TCXO-1 when using the K3EXREF? Unfortunately I do neither have the measuring equipment to measure below 1 Hz drift (and I'm not seeing that amount with my TCXO-1 only K3) nor a TCXO-3. So will the radio drift by 0.0014 Hz with the TCXO-1 + K3EXREF within those 4 seconds and the TCXO-3 will bring it down to 0.00028 Hz? Then I'm probably fine with the TCXO-1 and even the most sophisticated digital modes available. ;-) 73, Olli - DH8BQA Contest, DX & radio projects: http://www.dh8bqa.de Am 13.03.2016 um 04:23 schrieb Edward R Cole: Olli, Referring to page 8 in the K3 Owner's Manual (may be a different page for the K3s): "Frequency Stability +/- 5 ppm for the TCXO standard; +/- 1ppm for the optional TCXO." TCXO-1 and TCXO-3 respectively mentioned above. ppm means one part per million (1Hz per million Hz which is 1Hz per MHz). So frequency drift is proportional to the operating frequency. 1ppm at 10-MHz is 10-Hz;1ppm at 28-MHz is 28-Hz TCXO-1 provides 5ppm (+/- 50 Hz at 10-MHz and +/- 140 Hz at 28-MHz) TCXO-3 provides 1ppm (+/- 10 Hz at 10-MHz and +/- 28 Hz at 28-MHz) the basic frequency stability is determined by which TCXO is installed in your K3. EXREF "essentially" checks frequency drift of whichever TCXO you have installed at a fixed time interval of about 4-seconds. It uses a high stability 10-MHz external signal to compare with the 49.380-MHz TCXO and corrects the drift that occurs over the 4-second interval. My measurements of the TCXO-3 show about half the published spec of 1ppm (14 Hz at 28-MHz) and the EXREF limits the drift of the TCXO-3 to about 2 Hz. If I had the TCXO-1 installed, I would expect five times as much drift. So which TCXO you install directly impacts frequency stability. The EXREF reduces that by about an order of five. The EXREF is not the source of stable LO but merely improves what you have installed. Does that clear it up? 73, Ed - KL7UW The question to ask is what amount of frequency stability and accuracy is important for your type of operations.
