Re: [Elecraft] K3 Need for compressor
n4lq wrote: It seems that without the compressor it is difficult to obtain full SSB output. I'm listening to a guy right now on 160m in QSO. He had is compression on and as can be expected, was picking up plenty of fan noise from his amplifier. He was advised to turn off the compression. This he did and the fan noise went away but he complained about insufficient drive to his amp and his K3 was only putting out 38 watts now. I don't have a decent peak reading wattmeter but I think weak RF output is a common complaint. It's rather surprising that the K3 doesn't have the option of a peak-holding RF output display, like the S-meter has. I just wonder if Elecraft expects everyone to run some degree of compression? Or are we interpreting the PWR meter on the K3 incorrectly? Mainly the latter. When the K3 says no compression, it's telling the truth. In contrast, most other rigs are using compression all the time - even when the speech processor is turned off - because there is peak limiting due to heavy ALC. The K3 is one of the few rigs that does it right... and because no good deed goes unpunished, it then suffers complaints of weak audio! To equal the compression that's always taking place in most other rigs, you probably *do* need to turn the K3's compression up a little. No harm in that - unlike most other rigs, a moderate amount of compression will simply make you sound louder. However, the complaint about fan noise is a valid one. As the compression is increased, the peak audio stays the same but the background noise comes up. Any transmitter with effective compression will also benefit from a noise gate or some other kind of nonlinear threshold, to reduce the noise background when there's no actual speech. This would be something like VOX, but with a different configurable threshold and hold/release dynamics.

It may well be the case that to guarantee a bandwidth of at least 250 Hz, without doing expensive select on test procedures for the capacitors, one will have some samples at 370 Hz.

And anyway, the fan noise doesn't usually come from behind the microphone. In most shack layouts the amplifier is off to one side, and the noise bounces off the walls and ceiling, and arrives at the mic from all directions. -- 73 from Ian GM3SEK http://www.ifwtech.co.uk/g3sek ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3: Using built in PSK?
Hi- On Tuesday, May 27, 2008 8:58 PM, I sent this message to the reflector and haven't seen any comments... maybe I am too anxious, but I am also anxious to cure this problem- so again, I say: Hi- OK, the K3 works fine using computer generated PSK 31 AFSK, but when I go to the internally generated PSK 31 D, 31 bps, I do not get responses to my calling CQ or calling stations. The TX and RX filter width is set to 2.7 KHz. I can copy perfectly on the radios VFO B copy line and do get a kick out of the auto spot feature. I can hear the transmitted signal on my other rig (ORION II), but it doesn't have the fullness of the AFSK sent PSK. Any ideas? On a related note, one poster mentioned the use of the built in ability of the K3 to notify other net users of external computer problems, maybe so. However when monitoring my AFSK PSK31 signal from the K3 on my OII, I don't see the AFSK PSK31 signal on the same waterfall of the MixW software. That leads me to believe that you can not switch from computer driven AFSK PSK31 to built in PSK D PSK31 because they are on different frequencies. Tell me I am wrong and tell me how ot make it right.

I am led to believe these filters do not vary widely in manufacturing. So it would appear that a 400 hz/250 hz combinations is not a particularly good combination. The 200 hz may well be a better choice if you want to go that narrow. I have the 400 hz/200 hz combination, but I find I don't use the 200 hz filter nearly as much as I thought I would. I think that is primarily due to the fact I just don't seem to need to go that narrow, which speaks well for the K3 generally. I have used narrow filters a lot in other radios, but those were audio filters, not roofing filters. The DSP in the K3 seems to provide just about any additional filtering I need while using the 400 hz filter. Digital ops may actually find the 200 hz filter more useful. But I haven't really given my K3 a good baptism under contest fire. I missed the CQ WPX contest last week, and that would have been a great test for the narrow filter I think. I can also tell you from my experience that you need to set the 200 hz filter (and presumably the 250 hz filter) up with more gain added than they recommend in the manual. There seems to be a very noticeable reduction in signal level when the 200 hz filter is engaged. I believe this is on the to do list that Wayne has--to improve this signal level issue. I think Bill has analyzed the filter combination issue more than just about anyone. You may want to go back through the archives and read some of his prior posts to get some good insight about selecting various filter combinations. He may not be the last word on the subject, but I think it will give you added perspective.

Since the 400 is actually 435 and the 250 is actually 370, there is only 65 Hz difference in this combination and you'll probably never notice the difference between them (370/435 = only 15% narrower). Total cost $250. I think you are generalising from a single sample. It may well be the case that to guarantee a bandwidth of at least 250 Hz, without doing expensive select on test procedures for the capacitors, one will have some samples at 370 Hz.

Re: [Elecraft] K3: Using built in PSK?
Dave, Are you in Data-A mode when using audio based PSK31? If so, adjust your filter FC to 1.0. The BW can be what you want it to be, I normally start mine off at 1.0 kHz. If you transmit your signal right at 1.0 kHz on the waterfall in Data-A it should be the same as when using PSK-D. PSK-D uses a default of 1.0 kHz. But it creates its own audio tones instead of using an external soundcard. If when you are using Data-A you are somewhere other than 1.0 kHz for your audio, then no, the PSK-D signal will not be at the same place, it will always be at 1.0 kHz. Also, when using PSK-D you do not need to adjust the filter FC, it will already be at 1.0 by default. - 73, Greg - AB7R Whidbey Island WA NA-065 On Thu May 29 5:44 , Dave sent: Hi- On Tuesday, May 27, 2008 8:58 PM, I sent this message to the reflector and haven't seen any comments... maybe I am too anxious, but I am also anxious to cure this problem- so again, I say: Hi- OK, the K3 works fine using computer generated PSK 31 AFSK, but when I go to the internally generated PSK 31 D, 31 bps, I do not get responses to my calling CQ or calling stations.

Re: [Elecraft] K3 Need for compressor
Hello Ian! ... Any transmitter with effective compression will also benefit from a noise gate or some other kind of nonlinear threshold, to reduce the noise background when there's no actual speech. This would be something like VOX, but with a different configurable threshold and hold/release dynamics. To obtain full value from the K3's highly effective compressor, could a noise gate be added to 'Lyle's List', please? Instead of a Noise Gate with two or three variables, I've implemented an *experimental* Downward Expander with a single variable (threshold). It certainly kills the background noise here!

[Elecraft] K3: A funny thing happened
A strange subject, but this one has me baffled. I use the K3 with an Icom AH-4 tuner (tuning manually initiated) on the roof above me and below the centre of a long doublet. I've used this configuration with several radios over the last 5 years or so and it's never given me grief. I was on 30m cw, swr about 1.1 when suddenly I noticed my output drop from 100W to about 40W and the swr had risen to 4 or so. I hit the little button on my homebrew unit and the AH-4 retuned, but still with a high swr. The odd thing was that it was clear that as a result of this that the other station could no longer hear me. We were about 589 both ways so a 3 or 4dB drop in power would not cause that. I am wondering if I was transmitting somewhere else, and not on 30m. I changed to other bands and they all tuned fine. Went back to 30m, still the same apparent high swr. Then as suddenly as the problem had arrived it departed. As I was sending a chain of dots in frustration, the swr dropped right back down to just above 1.0 _without_ me having to initiate the tune- and that's what I don't follow! Hope that makes more sense to someone than it does to me. I'm really enjoying the K3 and even my wife prefers it to the K2 or TS-480, as she derives pleasure from spinnning the vfo whilst on the telephone at my desk! She still thinks the IC-7400 was prettier though! 73 Stephen G4SJP ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] K3 Bandswitching-My experiences to Date
Steve and All, A point well taken Steve. But setting up the the memories this way (if really deemed necessary!) is an owner convenience really. And if you don't use it yourself enough to do it without a sticky note, then it probably wasn't that convenient in the first place. If I had set it up this way, and a friend wanted to use the radio, I'd just tell him to use the regular bandswitch buttons. A visitor will have enough trouble operating any strange rig, so you don't want to add to the problem with operating tricks the radio allows you to implement--at least not initially. I'm a little mystified by the passion some folks seem to have about accelerating the band switching process. Do you really switch bands that much? I suppose some do. And my judgement may be tainted a bit right now by the lack of activity on a bunch of the bands higher up. For me, I'm usually just going between 3, or maybe 4 bands, which are all contiguous on the band rotation. Pushing the up/down bandswitch works pretty well for that. I'm just grateful they put both an up and down switch on the K3 instead of making you rotate all the way through like you have to do on rigs like the Argonaut V. When I had one of those radios, I found it very frustrating to have to go all the way around to get from 30 meters back to 40 meters. I sort of solved that by putting one VFO on one band, and the other VFO on the other. Then I could just use the A/B button. Nonetheless, I suspect that you are more or less correct that a couple more inches or so on the front panel would have accomodated a bandswitching keypad. It might have accomodated 2 or 3 more knobs as well for other things. But it would have added considerably to the volume of the radio. For some this would have been a good thing, and for others it would have been a waste. I suspect all of us have at least 1 or 2 changes we would like to see in the K3. Problem is, our wish lists probably don't always match up very consistently. The process of deciding how to design a radio like this seems very complex to me. Just think about how many questions need to be considered regarding each control and feature. It really suggests some powerful product/market research is needed, and to be honest, I don't think Elecraft is big enough to provide/engage/conduct this type of study. So, we end up with someone's (Wayne's mostly I suppose) best guess. And it sure won't be perfect. Wayne did a pretty good job I think, but it ain't perfect! But thank goodness he's an operator, in addition to being the designer, so he didn't saddle us with a multitude of compromises like Yaesu does perhaps? Then there are radios like Ten-Tec Orions, and Icom 7700/7800's, that put everything under the sun on front panel. But look at the size of those radios! You almost have to renovate your operating desk to accomodate them. And when you look inside of one of them one of the first things you notice is a ton of wasted space. But, if you aren't going to be moving the radio around much, that's very possibly quite acceptable. The K3 is a compact (but not too compact?), but reasonably full featured, radio. A lot of things were left out though, and many of them will perhaps be incorporated in the K4! The K3 was a substantial improvement on the K2, and the K4 will be a substantial improvement on the K3. If the next set of changes aren't all that substantial, they might just call it the K3A I don't even know if a K4 is on the drawing board, but I bet pieces of it at least are already in Wayne's head. A keypad band entry may very will be high on the list. I'd almost bet a bandscope is high on the list. QRO folks will be glad to learn that, out of the box, it will have provision for negative ALC! I'm being a bit facetious, but I would probably like having these features myself--some just in case, but appreciated nonetheless. We are all still looking for the perfect radio. If and when you think you have found it, you can bet that a bunch of others will be loudly lamenting that it doesn't have this or that. My advice to folks who are excessively frustrated by omissions on the K3 is to start dropping your loose change in a cookie jar to save up for the K4. A friend of mine recently told me he saved up nearly $1200 by just dropping the quarters in a jar he got in change, mostly from stopping after work for a beer! This made me realize a couple of things: 1. You can really save a bunch of money by doing this with loose change; 2. My friend probably drinks too much! Nevertheless, I think you have plenty of time.

I wonder if these folks have ever read FCC Part 97.307 (a) Emission Standards: (a) No amateur station transmission shall occupy more bandwidth than necessary for the information rate and emission type being transmitted, in accordance with good amateur practice. Bill, The problem with Section 97.307(a) lies in its drafting and purpose. The plain-language meaning of this section infers that as long as the transmission occupies no more bandwidth than that necessary for the emission type we are trying to achieve, then we are complaint with the rule, subject to good amateur practice. For example, suppose my intent is to use ITU designator 3K00J3E (i.e., 3 kHz SSB bandwidth). My intent is to use 3 kHz of occupied bandwidth and clearly, the ITU designator sets the emission type as stated in the aforementioned rule. Taking this one step further, if my desired occupied bandwidth is 3 kHz under the ITU 3K00J3E designator, then as long as I remain within that boundary I have set for the emission type being transmitted, I am fully-complaint with the rule (see my bandwidth boundary caveat at the end). In fact, suppose I wish to transmit with 6 kHz of SSB bandwidth and my desired emission type is 6K00J3E under the ITU designator. Pursuant to the rules, that transmission can be fully-complaint as well. However, this also presumes that any such transmission -- no matter what the actual bandwidth -- does not cause interference to existing transmissions. Whether the actual transmitted bandwidth is 1.8 kHz of 6 kHz, there's always a propensity to cause some interference to existing transmissions. Moreover, terms like good amateur practice and information rate should never be codified into rules regulations unless these terms are incorporated by reference into definitions in the preamble of the rules. Only, the original framers of Sec. 97.307(a) likely wanted to keep this section open for experimentation purposes without the necessity of placing hard bandwidth restrictions on emissions that could otherwise thwart the benefits of experimenting with various modes that exist today -- and those modes that may become developed at some point in the future. Enforcement of 97.307(a) would never, and could never, stand up to Constitutional scrutiny on the basis of the rule's arbitrary, capricious, and vague drafting. Another problem that surfaces when we establish hard occupied bandwidth rules is the necessity to monitor the bandwidth of emissions (to ensure 100% compliance) and the lack of a reasonable means for the average licensee to measure such. Also, codified bandwidth regulations would require setting measurement limits at the spectrum edges. For example, at what point is a 3K00J3E no longer compliant? Perhaps at -26 dB Peak Power? - 50 dB Peak Power? It gets real messy, real fast. Paul, W9AC ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] K3 Bandswitching-My experiences to Date
I'm a little mystified by the passion some folks seem to have about accelerating the band switching process. Do you really switch bands that much? I suppose some do. The issue (at least for me) isn't speed. The issue is reliability and user friendliness. The reason why so many of us are concocting band-switching mechanisms using the various memory options is that the supplied band switch buttons, at least with the present firmware, can become corrupted with other frequencies when listening outside the ham bands. I find this unsettling. In my opinion there are at least two controls on a ham rig that should be totally intuitive, robust and definitive in their operation - the on/off switch and the band switch. The band switch, in its present form, does not meet these criteria. For the K4 I would recommend a dedicated switch with detents, tactile/audio feedback, a DEDICATED keypad or some other method of accomplishing this. For the K3, I am hopeful that a future firmware release will make the current band switch operate as expected as well as provide for a convenient method for shortwave listening and general browsing. ...

The same was true with the Fox Tango filers before the filter line was acquired by W2VJN many years ago. All of the filers are slightly wider than nominal so that the effective bandwidth of two cascaded filters (e.g., 8 MHz and 455 KHz) is approximately nominal. Unfortunately, the 8 and 9 MHz filters in particular are significantly wider than the notational value in the narrow values - more than necessary to maintain the desired bandwidth in cascade. 73, ...

[Elecraft] K3: too easy to overwrite dial memories
Leigh The whole VFO/memory management with the K3 is very poor. Other transceivers, many at less than half the price of a K3, have a V/M switch so you are either using it in VFO mode or channel mode, even being able to scan the memories. Having to press a button then rotate the main dial knob, then press another button to listen to each of the 60m channels, one channel at the time is hopeless. It's just as well I have my TS480 for 60m as the K3 is so awkward to use in a channelised manner! 73 Dave, G4AON K3/100 #80 - For about the 3rd or 4th time I've tapped V-M, selected a memory (on of the 60m spot frequencies, the only global memories I have), rotated the VFO dial, and then tapped V-M again and overwrote the memory with the current VFO setting. Once the 2nd RX gets out it would be nice to get some attention paid to the memories; channel mode, especially for 60m but probably also for general use (think mobile ops; another K3 owner has suggested the VFO B knob for this.), making it harder to overwrite, etc. Leigh/WA5ZNU ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Noise gates have been unsatisfactory in my experience, usually being difficult to set up and introducing unwanted clicks and abrupt level changes into the audio stream. A smooth operating downward expander is a far better choice. I currently use a Behringer VX-2000 to drive the microphone input via a -20db voltage pad. My primary reasons for using the unit are the downward expander and the flexible input circuit for balanced microphones (and phantom power if needed).

Take a look at the Digital Interface box for the K2 on my website http://w3fpr.qrpradio.com and perhaps you can find some ideas. The interfacing is not hard as long as you don't want extra 'whiz-bang' features that are included with the commercial models. Also while at my website, take a look at the K2 Fixed Audio output. If you find that desirable, Tom Hammond has boards that will allow you to mount it between the front panel and the control board. See www.n0ss.net for more information on the fixed audio boards. With the fixed audio piped to a spare pin on your microphone jack and the interface box, you can have just one cable to the K2 microphone jack for all your soundcard generated data modes. 73, Don W3FPR Yves Dussault wrote: I would like suggestions on interfacing the K2 and suggestions...

RE: [Elecraft] K3: too easy to overwrite dial memories
For example, a (hypothetical!) button that shuts down the jet engines on an aircraft requires a confirmation step... because turning off the engines until the pilot hits UnDo would be bad! This rule applies to software as well as hardware. -- Eric K3NA This has no bearing on the current discussion but might be interesting to some. The button that shuts down jet engines is protected only by the human instinct to survive. We sit there for thousands of hours in the cockpit and never have any impulse to move those switches to the cutoff position, except during an intentional engine shutdown. (You usually have to lift and move to get to the cutoff position; you can't brush against them and move them.) I can only recall one case where a B767 pilot moved both switches to the cutoff position unintentionally. He thought they were something else I think. That event had a happy outcome. He did resort to an undo procedure. Some airplanes with overhead panel pushbutton fire switches are guarded mechanically to avoid hitting them with your head or shoulder when you get out of your seat. (The fire switches cut off fuel to the engine, among other things.)

Re: [Elecraft] K3 Need for compressor?
One thing that hasn't been mentioned is that if a guy is complaining about your shack noise being heard between your sentences or even words, it simply means that your signal, to this guy, is extremely strong, and he has his AGC set too fast, so that it tries to follow the audo waveform. Inreasing the AGC time constant (setting it to medium to slow) and/or kicking in the attenuator and/or turning off the preamp, or some combination of these, typically solves the problem (assuming the K3 TX really is set up properly -- not too much mic gain / compression, etc.). Guys have been amazed at how much better I sound after I tell them this. :-) Of course, approaching the issue from the K3 TX side is completely valid as well. Bill W5WVO Ian White GM3SEK wrote: Charles Harpole wrote: How about just using a good mic that is dead to its back and thus leaves out virtually all fan noise? That only means you don't have a big enough amplifier yet :-) The main thing that reduces fan noise on the outgoing signal is close-talking and turning the mic gain down; but directional microphones then suffer from proximity effects, giving too much emphasis on the bass (cue Jim Brown). And anyway, the fan noise doesn't usually come from behind the microphone. In most shack layouts the amplifier is off to one side, and the noise bounces off the walls and ceiling, and arrives at the mic from all directions. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 - RIT XIT
Hi, Yes, why would you want it to stay on when changing band or QSYing. Both result in a whole new scenario where RIT or XIT are probably not required, at least initially. Also with regards to memory management, I certainly don't want a load of nanny steps to stop me mucking it up. As has already been mentioned, you soon learn not to stuff it up. I prefer to need to think a little. Been listening to the K2 and K3 on the same beacon signal, noticeable delay in the signal passing through the K3. No problem but maybe the nano second band change QRQ people might wonder why the other guy has gone back to someone else whilst your DSP filters are emptying.

RE: [Elecraft] K3: band-bitch
These are interesting comments. I don't really mind cycling up and down the bands and doing a bit of knob turning. I simply push the button for fast tuning and be done with it. Band stacking registers would have been a nice feature but I guess you can't have everything. About the only small problem I have had, bearing in mind that I have had the K-3 for only about two weeks, is that I tend to cause the band to switch down when I am trying to activate the vox. I often don't hold the button long enough and so it lowers the band rather than activating the vox. I think that is a matter that will just require getting used to.

Re: [Elecraft] K3 Band changing...
We are indeed spoiled. If Elecraft could just fix the disappearing of ham bands on the BAND button when tuning to a non-ham-band frequency, I would be happy as punch. Not all radios have a dedicated button for each band (at least 11), which is really a waste of panel space. I have been happy band-switching (up/down buttons) with my IC-718 for years, but it doesn't have the Elecraft disappearance quirk.

Re: [Elecraft] K3: A funny thing happened
Forgot one thing about the 30m VSWR situation: While the ATU was trying to tune the antenna, it started at something like 25-1. It got down to about 6-1 after quite a bit of noise, but all during this time my external wattmeter indicated zero power output. On all the other bands, it shows a low power while tuning. It also produced no power when I keyed it after tuning. 73, Fred K6DGW - Northern California Contest Club - CU in the 2008 Cal QSO Party 4-5 Oct 08 - www.cqp.org ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K3 Need for compressor
If we are talking about modifying the K3 transmit audio, we also might want to look at installing a phase rotator, or phase scrambler. Most male voices are very asymmetrical. This presents a real problem with broadcast radio, especially AM. With US AM transmission, you are allowed 100% negative modulation, and 125% positive modulation. With a proper AM transmitter and audio chain, and the 125% positive limiter disabled, and the right type of a male voice, you can get 175-200% positive modulation while never exceeding 100% negative. Flip the polarity of the audio driving the transmitter, and you will cause carrier clipping on the negative modulation, while never going over 60-75% positive modulation. The broadcast equipment manufactures will many times look at the asymmetrical waveform and flip the polarity of the audio signal. Today, most stations depend on the microphone processor to balance out the microphone audio, by simple phase scrambling of the low end of the audio. This effect smooths out the sound of many male voices. I can turn the phase rotator on and off on my radio stations microphone processors off (Symetrix 528e's), and my announcers will complain that their voices sound a little brittle. If you have ever look at your SSB signal on an oscilloscope, you may have noticed that the waveform goes higher in one direction than another. It might be interesting to experiment with external processors on the effect, or lack of effect that phase scrambling might do for SSB. You can read up on how you can do this at several places: W3AM does a good job at: http://www.w3am.com/8poleapf.html http://www.nu9n.com/am.html http://www.omniaaudio.com/tech/speech.htm http://www.euphonicmasters.com/orban_article.php pdf of above at: http://www.orban.com/support/orban/techtopics/Appdx_Radio_Ready_The_Truth_1.3.pdf tom bosscher K8TB ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
