I believe the IIR filters ring more BECAUSE they have steeper skirts. As I explained in a previous message, FIR and IIR filters have similar ringing characteristics if the bandwidth and shape factors are the same. FIR filters cannot ring in the full sense of the word. What they can do is to generate a finite pulse of a particular frequency, but that pulse is never longer than the filter length. Long filter lengths result in a delay in the signal, which can become unacceptable in itself, so systems are not designed with extremely long filters. Some basic examples of (non-ringing - or rather ringing at 0Hz) filters are the rolling and exponential average. The rolling average is the average of the last n values and is an FIR filter. The exponential average adds x% of the input to (100-x%) of the previous output and is an IIR. (The simple rolling average is special in that you can use an IIR type algorithm to compute it, although the result is still only finite impulse response. That formulation of rolling average requires 2 additions per sample, whereas the FIR style one requires n.) -- David Woolley The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio List Guidelines http://www.elecraft.com/elecraft_list_guidelines.htm ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Dummy's Guide to Noise Reduction
To all NR 'confusees', Since getting my K3 #145 I've seen the discussion about Noise Reduction go round the block 2 or 3 times and I have to wonder if folk bother reading the FAQ which I've copied below... How does the Noise Reduction work? NR depends on correlation of the present input with previous input. The system does not actually provide Noise Reduction; it provides Signal Selection. In other words, its default is to pass nothing at all. It has to believe there is a signal present, and then it builds a filter, or set of filters, around the spectral components of the signal it thinks is there. Random noise has no correlation, voice has moderate but not perfect (unless you whistle a pure tone) and CW has excellent correlation. As a result, noise is heavily suppressed (no filter is built to pass it), voice is partially suppressed (hence it needs some additional gain to compensate for this effect so the same AF level will produce about the same audio level with a moderate S/N speech signal) and CW is hardly suppressed at all (hence it does not need any gain boost). NR is not recommended in Data Mode. Data is already getting a matched filter in the demodulator. You might lose a few symbols as the NR settles around the signal, and it might suppress a very weak signal that you could otherwise copy. NR in the end is intended for modes you listen to. Seems clear to me; I'm no expert (DSP 'dummy') but it tells me for one thing that adaptive dsp filtering is going to work better with cw than phone. There is more on it in 'Operating Tips' and somewhere Lyle gave a good explanation of the different settings available but I can't find it now - anyone know whether it's lurking somewhere on the web site?

Re: [Elecraft] [OT] Hilberling PT-8000 cancelled.
This PT-8000 must have cost Hilberling a few million euro at least. Three stands at the big Friedrichshafen show (I am sure they were there in 2006), development and salaries and... I am sure Hilberling's company can afford this, it has a very high reputation and he holds some very fine patents. I was always skeptical as the price was so very high - 11,990 euro for a 100W single RX radio (no panoramic display) is a lot, even if it does come with a nice microphone.

Re: [Elecraft] K3 :: slightly reduced TX power output noticed
When I make keydown at the 120 Watt level on 20 meters, the message HI CUR appears after about 10 seconds and the power goes to 106 watts. I did not see that before. 73 's Steef PA2A k3 #1184 - Original Message - From: Steve Jackson [EMAIL PROTECTED] To: elecraft@mailman.qth.net Sent: Friday, July 25, 2008 5:51 AM Subject: [Elecraft] K3 :: slightly reduced TX power output noticed Hello I noticed CW output power on 40M was off by a small amount, 7-10%. (Was set to 100W.) Meters are Bird 43 and LP-100. 2 kW dummy load has mondo return loss (26 dB). So, I went to see what the 40 meter HP TX gain setting was, and it seems like it was topped out. K3 didn't quite make the same power it did before, maybe 8% low. Odd, so, I cranked the TXG setting to 60, which is max. Still didn't quite make 50W. Then I noticed that the gain setting reverted back to 58 without my input. Huh? Turned the TX ALC back on, then checked TX out on 40M at 50W ... and got 50 watts. Cool. But ~7 watts low at 100W setting. HP TX gain setting, for comparison, on 20M is 24. It's like it has no headroom on 40M. My K2 was hottest on 40, IIRC. Checked power on 20M at 50W, right on the money. At 100W, 7-10% low, and much the same on other bands. Internal voltmeter shows 13.6V on RX and 12.9V on TX @ 100W setting, drawing 17.7A for 94W out on 7050. 50W out setting yields 50.4W RF at 13.15A @ 13.1V. Power source is an Astron RS-35M across three 105A-h AGM batteries, and nothing smaller than 10AWG in between. West Mountain Radio crimper tool assembled PowerPoles, the shack standard here for years. Probably have 100s of them. I don't think this is an I^2R problem. All 3 RF wattmeters agree at 50W. FWIW I just upgraded to the new firmware this evening. Since 92 watts equals 100 in my book and because at 50W the set makes 50W, this isn't too much of a concern. However, I thought I'd bring it up in case the observation is indicative of something else that actually does matter.

[Elecraft] a thought for more easier K2 building
Hello Group, While I built more than 10 K2 in the past, K3 and XV144 etc, I could not resist the attraction of kit building. Then I have recently started to build a K2 again (may be my 15th one). For the K2 builders, perhaps, you will remember that all the resistors are packed in an order according to the build sequence. I would wonder whether this arrangement can be applied to the capacitors as well. I spent quite some time to sort the capacitors. Some of them are quite small and difficult to read the value. Therefore, if the capacitors can be packed in similar arrangement as the resistors, it would be wonderful for a habital builder like myself. 73 Johnny Siu VR2XMC p.s.

So if someone has the time might you walk me through the settings you use for the K3 and RTTY? Roofing filter, offsets (if any) and such? I use the AFSK or FSK submodes of DATA. PITCH is set to the same as the PC program (I have tested with DM780, MultiPSK and MMTTY) or external decoder (I have tested with KAM Plus, PK-232 and PTCIIex. I expect a DXP-38 to arrive today so I can test with it as well). Note the dual tone filter is set for 170 Hz shift. Copying the W1AW RTTY bulletin works fine (170 Hz shift, 45.45 bps), but copying the AMTOR-B bulletins does not work well (200Hz shift 100 bps). Use the CWT function on the K3 for tuning in AFSK or FSK modes for equal deflection of the two bars in the display. The internal decoder, if enabled, will scroll text. It is using the dual tone filter, even if you have not selected it. Be sure the PC program or external decoder is set for the same tone polarity as the K3. The PTCIIex, for example, expects USB so you have to issue TONES 3 to reverse the tones when using it in AFSK or FSK modes on the K3. 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Northern Lights explained
I thought all you Elecrafters out there would find this interesting: Mystery of northern lights revealed SATELLITES: Magnetic explosions in space trigger the dancing displays. By MARCIA DUNN The Associated Press CAPE CANAVERAL, Fla. -- Scientists have exposed some of the mystery behind the northern lights. On Thursday, NASA released findings that indicate magnetic explosions about one-third of the way to the moon cause the northern lights, or aurora Borealis, to burst in spectacular shapes and colors, and dance across the sky. The findings should help scientists better understand the more powerful but less common geomagnetic storms that can knock out satellites, harm astronauts in orbit and disrupt power and communications on Earth, scientists said. A fleet of five small satellites, called Themis, observed the beginning of a geomagnetic storm in February, while ground observatories in Canada and Alaska recorded the brightening of the northern lights. The southern lights -- aurora Australis -- also brightened and darted across the sky at the same time. These auroral flare-ups occur every two or three days, on average. A team led by University of California, Los Angeles, scientist Vassilis Angelopoulos confirmed that the observed storm about 80,000 miles from Earth was triggered by a phenomenon known as magnetic reconnection. Every so often, the Earth's magnetic field lines are stretched like rubber bands by solar energy, snap, are thrown back to Earth and reconnect, in effect creating a short circuit. It's this stored-up energy that powers the northern and southern lights or, in other words, causes them to dance, according to Angelopoulos. An opposing theory has these geomagnetic events occurring much closer to Earth, about one-sixth of the way to the moon. More Themis observations are needed to resolve the debate, said David Sibeck, NASA's project scientist. Finally, we have the right instruments in the right place at the right time, and it's allowed scientists to be able to make the necessary observations to settle this heated debate once and for all, said Nicola Fox, a Johns Hopkins University scientist who was not involved in the study. At present, about 20 of these geomagnetic storms are being analyzed. Scientists hope to eventually learn, via this project, more about the bigger solar storms that occur about 10 times a year and can lead to far more expansive and prolonged northern and southern lights. The five Themis spacecraft -- a NASA acronym standing for Time History of Events and Macroscale Interactions during Substorms -- were launched aboard a single rocket last year. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Power Supply for K3 for Contest DXpeditions
Jose, I have a Jetstream JTPS28M Switching Power Supply that I have been using for over 18 months with two transceivers, including several 48 hour contests. It weighs 4 pounds, is compact, has two meters. I bought it from RL Electronics for $99.95. I am not a DX station and probably do not contest as hard as some DX stations, but it has held up nicely for me. My TS-850 and FT-900 draw about 3.5 amps on receive which I am sure is more than your two K3s. Key down on one transceiver is about 21 amps which it handles nicely. It will not handle transmit on both transceivers at one time.

Re: [Elecraft] K2 VFO Linearization fails
Bob, Have you first checked the PLL range? With the probe in TP3 (you may have to remove the KDSP2 or KAFT2), and menu in CAL FCTR - what is the frequency when you tap the BAND+ button? What frequency when you tap the BAND- button? If you have a good PLL range, then the frequency should decrement during CAL PLL. You say it does not, and I believe that, but start with the PLL range frequencies and then we can hone in on the problem spot. 73, Don W3FPR rrkrr wrote: K2 #3766, a kit I bought a few years ago and let sit on the shelf for a while - I'm finally threatening to finish it.

Re: [Elecraft] K3 died while attempting firmware download
I have had this on a number of occasions :- *** DON'T PANIC *** The Bad News is that something got screwed up on the recent firmware download. The Good News is that no harm was done, and your K3 is sitting there ready to try again. My advice would be to restart your computer, check your COM ports and wiring, particularly if you are using a USB to serial converter. Restart the configuration utility, and check that you have the correct port selected. Just tick the MCU, and the always load data tables boxes, and try to download again. With a following wind you should be back in business. 73 Stewart G3RXQ On Fri, 25 Jul 2008 12:58:27 -0400, Gary Nichols wrote: Help please.I killed w8uvz's K3 while trying to download current firmware.

Thanks Martin M0KWV, K1 ___ Don't know that technique Martin, but I have seen one or more party-type Mylar helium balloon - the kind sold in grocery stores, etc. - used successfully. It requires two people, sufficient room and quiet air. Two light threads are attached to the balloon(s). One thread is held by each person. The balloon is allowed to float up until it is well clear of the top of the tree, then one person walks around the tree to the opposite side, keeping the thread clear of branches, until in the desired position. Then one person pulls the thread in while the other lets thread out until the balloon is back at the ground level and the thread is draped over the tree. Now a string, then a cord, and finally a rope is attached and pulled over the tree. It's important that no power lines be where a runaway balloon and thread can reach them.

[Elecraft] K3 back to life again
Thanks to all who responded to my plea for help. It seems the problem was the brand new 15 ft DB9 serial cable I had bought just for this purpose so I didn't need to move the radio close to the computer to upgrade. I put together a 6ft 25pin cable with adapters to get to 9 pin male/female and connected that mess to the radio and was then able to successfully load firmware to bring the radio back to life. With the 15ft new cable it would stall out midway through the loading and freeze up the program.

RE: [Elecraft] ON4UN has a K3?
Glad to hear you ordered a second!!! I wonder if you used one of the newer label makers and printed up labels on a clear background how annoying they would look stuck over the buttons... Or you can always make it relatively easy to remember by using something like: 2 - 20 Meters 3 - 30 Meters 7 - 40 Meters 4 - 75/80 Meters 1 - 160 Meters Those are the somewhat easy ones to kinda fit in... Beyond that you have to either start getting creative or go for the labels. Or like you said...

Re: [Elecraft] K3: S meter calibration
Hello, I am not sure what your signal source is for your calibration and I have not researched this topoc on this reflector so it may be covered in detail by others. I will convey what I have found about S meter calibration. SMTR SC and SMTR OF affect each other so if you change on you have affeced the other. There are several combinations that will yeild S9. If you have a signal generator and or a power meter you will see the relationship. I tried the calibration with the Elecraft generator and found it to be accurate at S9 and S3 as advertised. When I checked the K3 S meter with my signal generator at values other than S9 and S3 I found the meter to be off significantly. Through trail and error using my 8640B sig gen I found that if I played with different values of SC and OF that I could bet the S meter do display very accurately from S1 to S9+30 and everything in between. If you have access to a good signal generator and spend some time you can make the S meter very accurate. If you only have the Elecraft generator you will be accurate at S3 and S9 but beyond that you wont know. I hope this helps, Ken, N0QO Graham Kimbell (G3TCT) wrote: I get very optimistic readings on my S meter above S9.

[Elecraft] K3 Firmware Stability - wrong description
We are not really talking about stability here. Generally, we are talking about variations is existing functions between versions that some weren't expecting. If there was a setting that got bumped accidentally during an upgrade, well, that's the way it is sometimes. Not a big deal and it gets fixed right away. The end result is more functionality in a radio that continues to grow even after you buy it. And if your idea of an additional or varied function is feasible, it may even be implemented. Try that with one of the other manufacturers. It would get posted in the break room as a joke. Think about this. You buy ANY other radio and you get what you bought, period. Like it or not. (Flex 5000 maybe??, but you have a better radio here). It MAY get a bug fix or two but it certainly will not get any enhancements and YOU certainly won't have any input. The concept of bringing the kit radio to the market, allowing you to configure it in the manner you like, and even upgrade it with other options later is what one could only hope for until now.

Re: Re: [Elecraft] Question - for Educational Purposes
On Fri, 2008-07-25 at 00:09, David Woolley (E.L) wrote: FIR filters cannot ring in the full sense of the word. What they can do is to generate a finite pulse of a particular frequency, but that pulse is never longer than the filter length. Long filter lengths result in a delay in the signal, which can become unacceptable in itself, so systems are not designed with extremely long filters. For signals received by the human ear, the filter length would have to be really long to be objectionable. For a symmetrical impulse response, the delay is 1/2 the filter length. For example, assuming a 10 kHz sample rate and a 1000-tap filter, the delay is only 1/20 second. To get a decent shape factor, the filter length in seconds needs to be at least a few times 1/bandwidth. Say 10/BW or so, resulting in 5/BW delay. So even with a 50 Hz bandwidth, the delay only needs to be on the order of 1/10 second. I don't think you'd ever notice that in normal on-the-air operation.

Re: [Elecraft] Northern Lights explained
Damn, I thought it was caused by magic. Jim Wiley-2 wrote: I thought all you Elecrafters out there would find this interesting: Mystery of northern lights revealed SATELLITES: Magnetic explosions in space trigger the dancing displays. By MARCIA DUNN The Associated Press CAPE CANAVERAL, Fla. -- Scientists have exposed some of the mystery behind the northern lights. On Thursday, NASA released findings that indicate magnetic explosions about one-third of the way to the moon cause the northern lights, or aurora Borealis, to burst in spectacular shapes and colors, and dance across the sky. The findings should help scientists better understand the more powerful but less common geomagnetic storms that can knock out satellites, harm astronauts in orbit and disrupt power and communications on Earth, scientists said. A fleet of five small satellites, called Themis, observed the beginning of a geomagnetic storm in February, while ground observatories in Canada and Alaska recorded the brightening of the northern lights. The southern lights -- aurora Australis -- also brightened and darted across the sky at the same time. These auroral flare-ups occur every two or three days, on average. A team led by University of California, Los Angeles, scientist Vassilis Angelopoulos confirmed that the observed storm about 80,000 miles from Earth was triggered by a phenomenon known as magnetic reconnection. Every so often, the Earth's magnetic field lines are stretched like rubber bands by solar energy, snap, are thrown back to Earth and reconnect, in effect creating a short circuit. It's this stored-up energy that powers the northern and southern lights or, in other words, causes them to dance, according to Angelopoulos. An opposing theory has these geomagnetic events occurring much closer to Earth, about one-sixth of the way to the moon. More Themis observations are needed to resolve the debate, said David Sibeck, NASA's project scientist. Finally, we have the right instruments in the right place at the right time, and it's allowed scientists to be able to make the necessary observations to settle this heated debate once and for all, said Nicola Fox, a Johns Hopkins University scientist who was not involved in the study. At present, about 20 of these geomagnetic storms are being analyzed. Scientists hope to eventually learn, via this project, more about the bigger solar storms that occur about 10 times a year and can lead to far more expansive and prolonged northern and southern lights. The five Themis spacecraft -- a NASA acronym standing for Time History of Events and Macroscale Interactions during Substorms -- were launched aboard a single rocket last year. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3: One more time - keypad/bandswitch
Don has it right. It doesn't matter how you set it up, as long as it is logical to you. My long time partner in crime and contest buddy Steve says he wants 40 and 20 etc. That''s okay, but probably won't happen in the near future. But I have to tell you, that when I had a rig with that type of set-up (meaning band buttons, such as the Kenwood TS940), I never actually looked at the label once I knew where they were. It was simply a physical location within a grid of buttons. I can still remember what was where but I'll be damned if I can tell what the buttons actually read (band vs freq in MHz).

Re: [Elecraft] ON4UN has a K3?
Yes, Don, I agree completely. Forget about the labels entirely and just learn them by key position. However, I went with a vertical scheme vs your horizontal one... The first keypad column (1,4,7) is 160, 80, 40. Second column is 20 to 6 (6m stands apart way down there on the zero key); third column is the warc bands. I figure if I can keep track of forty-some keys on a keyboard without looking then I can memorize the positions of ten band buttons on the k3. Now my band locations just seem right! No label reading; no mental translation... the buttons ARE the bands! So, if the power goes out I can navigate the bands without even needing to see the buttons.

Re: [Elecraft] K3: S meter calibration
Bill, My values are as follows but I am not sure how applicable they will be to another radio. I did the calibration with SMTR MD in the ABS setting so that the preamp in or out would not have an affect. I found that for the best accuracy it was necessary to do the calibration whichever SMTR MD mode you planned to operate (ABS or nor).

Re: [Elecraft] [OT] Hilberling PT-8000 canceled - let me get this straight
The announcement did *not* say that they did not meet standards, nor did they say that the standards were too high - they did say that they did not expect to meet the standards in production units at a cost they considered reasonable (whether those are EU compliance standards or internal company quality standards, it makes no difference). Quote: However, guaranteeing this high standard without limitations in a series production program with many vendors runs into difficulties which cannot be overcome at a cost level which is still acceptable. The engineers produced a product that was not reproducible within budget. Such is the fate of many 'sandbox' projects within a large company, budget is always an important parameter in any engineering task. During my working years, I have seen many projects canned because they could not come in on budget (I worked on one of those too) - no sense for the company to lose money on every piece of equipment they sell, that does not keep the stockholders happy. 73, Don W3FPR DOUGLAS ZWIEBEL wrote: Methinks there is more afoot than meets the eye. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

And take away my CW memory buttons? That's madness! No Nick - You keep your CW memory buttons - no madness there. Simply add one setup option for those of us that own external keyers (CMOS4 in my case) that if it is changed from the default will allow the single touch keys to be band switchers rather than keyer memories - see? A setup called maybe M1-M4 when set to default and those keys are for DVK or memory keyer just as you enjoy it now. Set to BAND and those uf us that want it get access to the VFO's. I'd go one stpe further and say that the M1-M4 could be mapped to 80m 40m 20m and 10m and a single press of the REC button would display briefly WARC on the display and then M1-M4 would be 60m 30m 17m and 12m.

There are times that a design engineer has to slightly degrade the performance of a product in order to meet these requirements.

Hey Doug - You hit the nail on the head, contestors have the optimal solution with the stock K3. But modest stations, what I'll call condo class or dipole class (like my own) require a scan of the available bands to see which -one- you can use on a given day. There is a fair amount of back and forth in determining which band to call home for a couple hours. With single touch band changes, you press one button (example 20m), twirl the main tuning knob, take a reading, okay now hit the next band up (15m), twirl, okay how about 10m? Nope, MUF not there, back to 15m. Your finger remembers single press bands, even between weekends (many of us work). Now imagine sitting down on Saturday morning after last operation a week ago - okay, hmmm, which button oh yeah - M-V, okay now which band is button 20m? Hmmm think it's 1. Two button press and you are there. Repeat 3 times as in example. Summary - one button is enough for even a finger to remember for a week.

Re: [Elecraft] Band Button gripe - was ON4UN has a K3?
Or you can just use an up/down and get done the working up the bands and scanning with the dial... Hell our forefathers had to tune up for quite some time to change bands. Now we've reached the point where using and up/down button set is too slow for us. Then god forbid we actually have to engage our brain and remember what band we have saved where. If its so hard put a band plan on the wall and just write a number next to each one in order. Then you can walk through them that way. But oh my gosh we have to press two buttons to get to each band If you're a condo/dipole class why not sit back and enjoy it. Maybe cut your QSO shorter by 3 seconds so you can get in those extra button presses for band changes. Maybe you can head to a fast food place and have them make you a meal that you can eat in the car without having to ever stop or get out. That should save you enough time for a few extra button presses to change bands. Personally I like the portability that a smaller/lighter rig affords me. Thankfully the K1, KX1, K2, and K3 pretty much all fit into that category. I don't think I'm alone in this though There has to be a reason why the IC706 is the best selling rig in the hobby and it has band up/dn buttons. Not that I own one though...

Re: [Elecraft] Band Button gripe
Idea Why not make an additional set of control buttons and use the secret connector on the bottom right side of the K3. Just a small panel that would fit under the K3 and would give you numerous programmable buttons. Then, you could set up the button on the little add on panel. Or, for quick band changes in a contestI use N1MM logger and just change bands and modes through software. Or, a stand alone PIC processor on the RS232 port that does the same thing as software in a computer. There are a lot of people who like to market add-ons to the Elecraft products that just work great. Fingerdimple, LP-PAN, etc...

Re: [Elecraft] Band Button gripe
These ideas make much more sense than trying to remap front panel buttons. I think the field testers did a great job of defining how the ergonomics are to flow. ~Brett On Fri, 2008-07-25 at 20:43 -0700, Lee Buller wrote: Idea Why not make an additional set of control buttons and use the secret connector on the bottom right side of the K3. Just a small panel that would fit under the K3 and would give you numerous programmable buttons. Then, you could set up the button on the little add on panel. Or, for quick band changes in a contestI use N1MM logger and just change bands and modes through software. Or, a stand alone PIC processor on the RS232 port that does the same thing as software in a computer. There are a lot of people who like to market add-ons to the Elecraft products that just work great. Fingerdimple, LP-PAN, etc...

Most people deal with WAY more than that on their cell phones every day.

What they can do is to generate a finite pulse of a particular frequency, but that pulse is never longer than the filter length. Long filter lengths result in a delay in the signal, which can become unacceptable in itself, so systems are not designed with extremely long filters. For signals received by the human ear, the filter length would have to be really long to be objectionable. For a symmetrical impulse response, the delay is 1/2 the filter length. For example, assuming a 10 kHz sample rate and a 1000-tap filter, the delay is only 1/20 second. To get a decent shape factor, the filter length in seconds needs to be at least a few times 1/bandwidth. Say 10/BW or so, resulting in 5/BW delay. So even with a 50 Hz bandwidth, the delay only needs to be on the order of 1/10 second. I don't think you'd ever notice that in normal on-the-air operation.
