[Elecraft] DSP Upgrade and Serial Number
So where is the SN stored in the K3? The people who received new upgraded DSP boards in the mail; did you get the serial number of the guy who had that board before you? When I got the upgraded DSP board I sent my board in and had it reworked so all my info was the same but the swaparoo makes me wonder if you end up with a new serial too. I gotta admit as a CW op I hate my SN (1116) but I still love my K3 so it balances out. Not a big deal either way this goes. I'm just curious.

[Elecraft] setting filter engage frequency
Thanks all.

[Elecraft] The Myth of Lying to Your K3
Setting the crystal filter engagement bandwidth is sometimes described as lying to your K3 when the number is different than the number on the filter. While this phrasing is cute and descriptive, it can be very misleading. There is no lie, but in fact a very precise setting that determines the DSP frequency at which the crystal filter engages. If anything, the user is lying to themselves. Some facts: 1. The bandwidth in the filter's marketing name is not the actual bandwidth of the filter. Some filters are significantly different than their name. For example, the KFL3A-250 250 Hz, narrow 8-pole filter is nominally 370Hz wide at the -6dB points. The KFL3A-400 400 Hz, narrow 8-pole filter is 435Hz. 2. The actual IF bandwidth of the K3 is determined by the cascade effect of the DSP and crystal filter bandwidths. When those bandwidths are close to one another, the actual IF bandwidth is significantly narrower. So, if you configure your K3 to engage the 250Hz filter (actually 370Hz) at 350Hz or 400Hz, the resultant bandwidth will be closer to 300Hz. 3. If you engage a crystal filter at a DSP bandwidth much greater than its actual bandwidth, then the K3 IF bandwidth will decrease immediately to the crystal filter bandwidth and the passband shape will be governed by the rounder shape of the crystal filter. Some users do this because they like the sound of the crystal filter passband shape compared to the sharper DSP passband. Keep in mind, though, that the bandwidth step at the crystal filter engagement point is much larger than the normal DSP steps. For example, if you have the 1.8kHz filter engage at 2.2kHz, you give up any IF bandwidth between 2.3kHz and 1.8kHz. The K3 WIDTH control shows the DSP bandwidth at values between 2.3-1.8kHz, but the actual K3 IF bandwidth is governed by the narrower 1.8kHz crystal filter and fixed at that bandwidth for these intermediate DSP bandwidths. Failure to recognize this fact is lying to yourself. 4. The crystal filter engagement point can alternatively be set at a DSP bandwidth much less than the actual crystal filter. In this case, the DSP bandwidth steps are consistent and represent the true IF bandwidth of the K3 at any time. The crystal filter is always wider than the DSP bandwidth and therefore does not cause the IF bandwidth to be narrower due to cascading. In this case, the K3 IF passband shape is governed by the sharper DSP shape and the crystal filter is only providing roofing filter protection for the DSP, which happens to be the primary function of the crystal filter. Any value you choose for a crystal filter to engage is valid. There is no right or wrong. There is no lie. The engagement point you choose is a simple fact. The important thing is to fully understand the implication of your choice so that you accomplish what you intend to accomplish.

If a USB port is provided for the sole purpose of sending control data then there is little if any advantage over the RS232 port aside from the fact your computer may not include one. If the radio is provided with a USB port then it should use the full potential and include the provision of in/out AF streaming as well. It is possible to use the USB port to both send and receive control data for CAT operation and stream in/out AF. After all if we're talking about 'flaky' devices ... the sound card provided by most computers is at the top of the list. If they (radio manufacturer) were to implement such a USB port then plugging it in would show up as a sound card in the computer. However, the majority of radios don't do this ... and implementing a USB port on this half basis in no improvement.

Re: [Elecraft] USB to serial angst
One can have the simple solution right now. Just get a USB to serial adapter that has jackscrews on its serail end and permanently mount it on the back of the K3 - cable over to a USB port on the computer and one has that simple solution. Support for the proper device drivers is the responsibility of the adapter manufacturer. The better and more complex solution is to build a complete USB interface inside the K3. When you connect it to a computer, it is recognized as an Elecraft K3 (not as a com port as the adapter would do) - then you load the driver(s) for your K3. Here are a few problems starting with the applications that many hams use. Those applications would have to be re-written to support the USB K3, so it will be a while before your favorite logger, etc. adds that product specific support as a USB device. Elecraft would have to spend a lot of time and resources creating the drivers for every conceivable OS that is in use (or limit the number of OS versions that will work with the K3). And then when a particular OS makes changes, spend a lot of time and effort doing regression testing to be certain it still works. When a new OS comes out, Elecraft would have to have new K3 drivers which support that new OS version (on the day that the OS is available) - for now and forevermore - the alternative is to declare the K3 as obsolete with respect to a computer connection. Keeping the drivers current is the responsibility of the device manufacturer unless the OS developer chooses to take over that device control and integrate support for it in the OS. I just can't see that happening for the K3 at Microsoft, Apple, Sun Microsystems, etc. The RS-232 standard provides a lot of protection from that kind of chaos for those devices that use a serial port. There are a lot of devices that use the serial port, and will continue to do so for a good long time, serial port communications is *not* obsolete. All a device has to do is decide if it is a DTE or a DCE in its design - usually the computer end is DCE. So I say sorry to those who want to use a laptop computer with only USB ports as the main hamshack computer. Why not dedicate a good desktop computer to the ham station. Modern off-lease desktop computers are available for as little as $150 loaded with WinXP Pro, many with 2 serial ports installed, and monitors are available for $99. So for a $250 investment, you can have all your ham applications on a dedicated computer. Add a router if you do not have a home network already and you can run that hamstation computer (and the K3 connected to it) from your laptop used anywhere in the world that you can obtain an internet connection. Computers have become commodity items. For my part, keep the serial interface, it will live long after USB is gone - there are too many commercial devices that use it for support to go away anytime soon. 73, Don W3FPR Brett Howard wrote: Actually its exactly that simple...

Re: [Elecraft] The Myth of Lying to Your K3
With you all the way until you said this: The crystal filter is always wider than the DSP bandwidth and therefore does not cause the IF bandwidth to be narrower due to cascading. To construe the sentence correctly requires the assumption that ONLY the shape INSIDE the rated 3 dB or 6 dB passband matters. It is true that this flat part of the curve is governed most by the characteristics of the narrower curve. HOWEVER, everything cascades. PARTICULARLY so on the skirts. When one is trying to listen to a signal at S1 just up a ways from a signal that is S9+30, it is the skirts that count the most. The losses on the two filtering curves in dB at a given frequency are ADDING together to create the 98+ dB needed to make the S1 signal comfortably louder than the unwanted signal. Note that merely down 78 db on the skirts makes them EQUAL. Another 20 dB is needed for the comfortable part. Neither the DSP nor the roofer will accomplish this on their own. It is the sum of the skirt losses. There is a point where the skirts on a roofing filter are the steepest. If the steepest part of the DSP curve is set to coincide, this will result in the most sudden and abrupt filtering out of the unwanted signal as one tunes across and will result in the least interfered open bandwidth around a run frequency. That is why I lie about the 8 pole 400 and 250 and call them 450 and 350. I WANT those super-sharp COMPOSITE skirts you get whenever the steep parts coincide. 73, Guy. On Sat, Mar 13, 2010 at 10:15 AM, Ed Muns w...@msn.com wrote: Setting the crystal filter engagement bandwidth is sometimes described as lying to your K3 when the number is different than the number on the filter. While this phrasing is cute and descriptive, it can be very misleading. There is no lie, but in fact a very precise setting that determines the DSP frequency at which the crystal filter engages. If anything, the user is lying to themselves. Some facts: 1. The bandwidth in the filter's marketing name is not the actual bandwidth of the filter. Some filters are significantly different than their name. For example, the KFL3A-250 250 Hz, narrow 8-pole filter is nominally 370Hz wide at the -6dB points. The KFL3A-400 400 Hz, narrow 8-pole filter is 435Hz. 2. The actual IF bandwidth of the K3 is determined by the cascade effect of the DSP and crystal filter bandwidths. When those bandwidths are close to one another, the actual IF bandwidth is significantly narrower. So, if you configure your K3 to engage the 250Hz filter (actually 370Hz) at 350Hz or 400Hz, the resultant bandwidth will be closer to 300Hz. 3. If you engage a crystal filter at a DSP bandwidth much greater than its actual bandwidth, then the K3 IF bandwidth will decrease immediately to the crystal filter bandwidth and the passband shape will be governed by the rounder shape of the crystal filter. Some users do this because they like the sound of the crystal filter passband shape compared to the sharper DSP passband. Keep in mind, though, that the bandwidth step at the crystal filter engagement point is much larger than the normal DSP steps. For example, if you have the 1.8kHz filter engage at 2.2kHz, you give up any IF bandwidth between 2.3kHz and 1.8kHz. The K3 WIDTH control shows the DSP bandwidth at values between 2.3-1.8kHz, but the actual K3 IF bandwidth is governed by the narrower 1.8kHz crystal filter and fixed at that bandwidth for these intermediate DSP bandwidths. Failure to recognize this fact is lying to yourself. 4. The crystal filter engagement point can alternatively be set at a DSP bandwidth much less than the actual crystal filter. In this case, the DSP bandwidth steps are consistent and represent the true IF bandwidth of the K3 at any time. The crystal filter is always wider than the DSP bandwidth and therefore does not cause the IF bandwidth to be narrower due to cascading. In this case, the K3 IF passband shape is governed by the sharper DSP shape and the crystal filter is only providing roofing filter protection for the DSP, which happens to be the primary function of the crystal filter. Any value you choose for a crystal filter to engage is valid. There is no right or wrong. There is no lie. The engagement point you choose is a simple fact. The important thing is to fully understand the implication of your choice so that you accomplish what you intend to accomplish.

Re: [Elecraft] USB to serial angst
Well said. There's no good reason for desktop Ham Radio computers to NOT have serial ports. The four port PCI serial card I bought for my new home brew machine cost $20. It works with all my operating systems, three at last count, and I don't have to do any sort of configuration. Shut the computer off, install the board, reboot. USB has NO advantage over RS-232 at the data speeds we're talking about and it brings a laundry list of potential problems that RS-232 just doesn't have. The reported obsolescence of RS-232 is highly exaggerated and premature. For the most part caused by folks who use compromise computers designed for portable use.

[Elecraft] SSB Net for Sunday March 14th
Given that the EQP event will be finishing just as the usually scheduled Elecraft SSB is to begin, there may be little interest. However, I'll kick the power up from 5w to about 500w and give it a try as fill-in NCS while Phil is away. Frequency: 14.314MHz (+/- a few kHz if necessary) Start time: 1800Z (don't forget to account for the Daylight Time adjust if it applies to your area) I'm in Denver, CO and have an LPDA and a low slung delta loop. There's a significant ring of silence around me so some help from either or both coasts for relays will be appreciated.

Re: [Elecraft] USB to serial angst
RS-232 port wins for simplicity and for easy troubleshooting. Elecraft made the right decision. When things don't seem to work right, being able to see the controls and data with a simple LED tester makes for quick problem solving. Alan Alan D.

Re: [Elecraft] K2 New Builder
You might also want to consider a vent fan to exhaust solder fumes from the area. I built a home-brew solution with an old muffin fan. You can see the photos at http://wilcoxengineering.com/projects/amateur-projects/29-vent-fumes The commercial versions are nicer, but this does do the job, at least for me. Enjoy the kit building!

Re: [Elecraft] K3: ACC Pin10?
Martin, ACC Pin 10 is a low power (10 ma. max) copy of the KEYOUT connector on the rear panel. It is open circuit until the K3 is keyed (or PTT or VOX), and then it goes to a closed circuit condition. So yes, the K3 pulls this pin to ground during transmit, and it should work well for keying a transverter. 73, Don W3FPR DM4iM wrote: What does this Pin exactly do?

Re: [Elecraft] K2 C44
Geo, You must have missed the note about C44 on page 22 of the manual - this capacitor is not used. As far as your extra capacitor, did you do a full inventory before you started including checking the number of capacitors of each value against the parts list? If you did that, you would have known for certain whether there was an extra (that sometimes happens - rare, but it happens). If you did not do a full inventory, I suggest you go to the parts list and check each location that has a .01 uF capacitor on the board. If all those locations have a .01 uF capacitor installed, then you can rest assured that you have an extra one. I know of no easier method. 73, Don W3FPR w2b...@aol.com wrote: Ref control board caps.

[Elecraft] Elecraft CW Net Announcement
Good Evening, I almost forgot about this. Oh for shame! I got caught up in Thistle Shamrock and then Live Wire. This radio thing is almost too exciting for words. I do miss the radio shows I used to hear on KAAY out of Little Rock and Beaker Street Theatre from the same venue. KAAY was a strong signal AM station. When the rest of the stations turned down their power at nightfall they covered the Midwest with a booming signal. The Green Hornet, The Shadow, The Lone Ranger, etc. used to keep me at the radio listening. These days I listen to dits and dahs far more often but in those days I had my brother's Lafayette receiver. I have had headphones stuck on my head since I was about five. I think it has effected my hearing :) Now on to more radio talk :) Propagation has been good this week. Even though the sun was blank for a day or two the effects of the recent sunspots have been lasting. Today I worked a number of folks on EQP and plan to go back and work a few more when I get this out to the world. It was fun to chat with those of you I knew and get to know a few others as I banged away. My fingers had cracked so I had bandaids on my right thumb and forefinger which was causing them to stick to the paddles. After flubbing more than my usual number of letters I got off the air and soaked my fingers in hydrogen peroxide. This helped enough to allow me to send without finger coverings. Much better code ensued. I am sure the op on the other end was thankful! I have changed the UTC time for future nets but as usual have maintained the local times. I checked this so I think I have it correct. I know I will be corrected if I am not. If these times do not fit the propagation for eithe r band they are subject to change. Don't touch that dial, we control the vertical ... Please join us tomorrow evening. 1) Hail signs (first letter or two of the suffix of your call) 2) NCS help (as well as QSP/QNP relay help) Sunday 2200z (Sunday 3 PM PST) 14050 kHz Sunday 2300z (Sunday 4 PM PST) 7045 kHz Stay warm, Kevin.

[Elecraft] [OT] CW app
This is a CW-centric bunch of people, so maybe this is semi-topical. A fairly large fraction of hams have either an iPhone or an iPod Touch. I have the latter. I've found a really good app for CW training. Maybe some of you pros can pass it along to your less gifted friends. It is Ham Morse by AA9PW. It has a fairly hostile user interface until you figure out how to use it. But, what it does is very useful. Basically, there are little things that look like dials. Once you stop trying to make them rotate, you realize that you just touch them to make them go to the next notch. + Speed adjustable from 5 to 50 wpm + Will send random five-letter groups, with the character-set user selectable. + Will send a fake QSO + Will send the top 100 or top 500 most used words, in random order + Will send pseudo-call signs (3 to 6 character groups of numbers and letters) + Will send you the RSS feed from various newspapers, in Morse. It is this last capability that is the kicker for me. I can sit down to breakfast, and listen to the BBC RSS feed in Morse. Below 15 WPM it uses 15 WPM Farnsworth. Tone is not adjustable. Can be heard even without ear buds. Not great, but audible enough to learn Morse from. Use earbuds to keep peace at the breakfast table. You pros could actually use it as your primary news source. Disclaimer: I have no stake in this. I don't know AA9PW, but do admire the cleverness of his app. The app costs $4.99, which is high for apps, but worth it IMHO. 73, Oliver W6ODJ __ 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] The Myth of Lying to Your K3
K2AV noted: The crystal filter is always wider than the DSP bandwidth and therefore does not cause the IF bandwidth to be narrower due to cascading. To construe the sentence correctly requires the assumption that ONLY the shape INSIDE the rated 3 dB or 6 dB passband matters. It is true that this flat part of the curve is governed most by the characteristics of the narrower curve. HOWEVER, everything cascades. PARTICULARLY so on the skirts. That's right. I chose to simplify the point by not getting into the skirt issues. It's clear from the posts on this reflector that the basics of this topic are not well understood, let alone the subtleties of the cascaded skirts.
