Re: [Elecraft] Firmware Stability
I've found upgrading to be VERY rewarding! Actually it wasn't too long ago that I was talking with Wayne when I'd had radio troubles and I'd mentioned that I wished there was a way to erase memories. He mentioned that he didn't understand why I'd want that when all I had to do was just write something else back over the top of it. Mainly its just cause I'm anal and like to have things clean and tidy Anyway he decided it was a relatively simple fix and poof it showed up. That was a fun one cause many other than myself appreciated that one. As well I had a slight problem in the way the scan feature worked. I sent an email to Wayne mentioning that I was having an issue that was very repeatable that resulted in the receiver being muted with no way to get out of it other than starting scanning again until it stops or power cycling the radio. There was a beta version of code that hadn't even been released yet that Wayne emailed me and poof my problem was solved. No remark of well you should buy the Elecraft K3 Mark IIG just oh here is a firmware update that resolves your exact issue. I should also mention that I got this update on a Sunday evening Wayne and Lyle and the rest of the Elecraft crew are working their ASSES off to keep these things moving forward and constantly improving. If a new firmware results in a regression I've seen that Wayne is VERY quick to jump on those and get those resolved. That's why often a release will result in several subsequent releases. My advice is most definitely keep up to date for several reasons. First off Wayne recommends it. Secondly the more people we have using the latest software the better it becomes as there are more people testing it out in more ways. We all operate slightly differently. If we were all the same then no issue would ever make it past the field testers. Lastly the more often you update your rig the more you are allowed to grow with it. Things can change quite a bit from a version of the code that you are running to the new code today. Upgrading more often can allow you to become accustomed to the changes and understand what is new. Its kinda like the difference between visiting with grandkids every few months or only getting to see them every 5 years. Only seeing them every 5 years results in a lot more shock each time as to how much they've changed rather than every few months. That and it results in MUCH less cheek pinching!!! I'm not old enough to have grandkids yet but hopefully my analogy makes sense :) Thanks Brett (KC7OTG) On Wed, 2008-07-23 at 22:03 -0500, BOB PHILBROOK wrote: I am sitting here with K3 #818 with firmware release 1.7X waiting a version of the K3 firmware to stabilize and be around for longer than a few days before a new version or new Bata development is released.

Zero beating WWV isn't so easy here in Norway, so I visited a friend who has a frequency counter. Turned out that the signal level at J1 of the reference oscillator was way too low for his counter.

Bob, K9PAG It's really easy to update the firmware (or go back to previous version) so I don't see any point in waiting for it to stabilize. I like the constant stream of fw revisions and enjoy installing them. Usually products which boast upgradeable firmware will have a revision or two (for major bug fixes) then that's it. With Elecraft you get the idea that they will be enhancing the operation of the rig, not just fixing a few major bugs and moving on to something else. Having said that, I only install the updates when they involve some feature that I'm interested in. I did the latest version because I'm interested in the AGC mods. I bet there are probably a number of firmware improvements since version 1.7 which you would enjoy having. Have you checked the revision history?

[Elecraft] K3 Firmware 2.19
Hi Roy: The latest revision of FW seems to have contributed greatly to the versatility of the K3. Lyle doesn't say much, but when he does you better listen good. The latest offering, IMHO, gives the K3 owner more choices than any other transceiver. Yes, some things seem to have changed with this release, but I'm not one to sit back and complain. I have learned so much more about the capabilities of this radio by going in and experimenting with all the parameters. I have found that I like AGC THR= 2-8 (7) and AGC SLP = 0-15 (8). The THR setting seems to have lower amplification at 2 and progressively increases as you go up to 8. With SLP the amplification seems greater at 0 and gets less at 15 but, the relative difference between weak and strong stations becomes flatter. This is where all the controversy seems to occur because various band conditions throughout the world will dictate different settings. Everyone has different preferences and this is what makes the K3 such a powerful radio. One cannot sit back on the defaults and then complain because one station is so much louder than another. The band condx lately have been up and down constantly. I have varied the settings going from 20 to 75, but not all the time. I think everyone seems to agree that experimentation is the best teacher. A note on the NR parameter. I found that the NR setting of 1-4 works for me. The AF volume control has big effect on NR. Try setting the CONFIG: AF GAIN LO. What this does is allows you to increase the rotation of the AF GAIN control to a higher setting which seems to control the NR audio much better. It also seems to make the audio much clearer and easier to listen to (less distortion). My control is usually at 10 o'clock to 12 o'clock for best listening. 73's Tony K2ZLS K3 #703 FW=2.19 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] [K3] Firmware Stability
Mike and all, Perhaps it also needs to be said that each release *is* stable. That is, it 'does what it does', and with very few exceptions, it does it well. Each release has been tested, and all the bugs identified by the Field Test group are fixed. Most releases offer additional function. In case there is a remaining major bug which is identified after the release goes public, you can be assured that it will be fixed in short order, and it will be publicized. A quick review of the firmware release notes will indicate how much is added function and how much is bug fixes, and I believe the added function parts win 'hands down'. I believe the situation with the K3 firmware is much different than the continuous string of updates offered by major software 'manufacturers'. Their continuous string of 'upgrades' do not normally include added function, but instead consist mainly of bug fixes and plugs for the security holes. A user may want to wait a few days after a new release is announced to see if any major bugs are identified, but I see no advantage to delay upgrading to the newest release. The Firmware Field Testers *do* see incremental changes, and I have loaded most every one as it is available (sometimes multiple times in a day), and I can say that my K3 has never been 'broken' with any release I have loaded, no failures observed here. 73, Don W3FPR Mike Scott wrote: I am sitting here with K3 #818 with firmware release 1.7X waiting a version of the K3 firmware to stabilize and be around for longer than a few days before a new version or new Bata development is released.

Re: [Elecraft] Question - for Educational Purposes
I've been doing some reading on the new firmware. I would like someone to explain (like I am a 3rd Grader) the different between IIR Filtering and FIR Filtering. Thanks. Essentially, IIR filters have feedback, so they can ring and in extreme cases oscillate. Think of an op-amp based audio filter, for example -- or a regenerative receiver. FIR filters have no feedback, so they cannot ring or oscillate. These filters are generally impractical to implement outside of DSP. For a clear, readable explanation see Experimental Methods in RF Design (EMRFD). If you have only one technical book in your library, it should be EMRFD in my opinion. Available from many places, including Elecraft :-) For more details and links while your copy of EMRFD arrives in the mail, see URL:http://en.wikipedia.org/wiki/IIR 73, Lyle KK7P ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] Question - for Educational Purposes
Lee, I do not know if it is 3rd grade level or not, but: Look at the ARRL Handbook chapter on DSP and Software Radio Design. In my 2005 Handbook, I believe the first 2 paragraphs of the sub-section on IIR Filters (page 16.6, last column) explains it about as well as any. In general, practical IIR filters can have steeper skirts, but do not have the linear phase response of the FIR filters. That usually means that the IIR filters will tend to ring while the FIR filters do not. At extremely narrow bandwidths, the IIR filters could be a better choice for your ears, but others find the ringing irritating - try both on your ears and pick the one that does the most good for you. Now if one can just find a crowded band where the difference can be adequately tested - that is another thing altogether, perhaps the weekend activity will provide a suitable test arena.

Re: [Elecraft] Question - for Educational Purposes
There is no third grade level explanation of these concepts. All discussions I have ever read trying to understand IIR, FIR and DSP in general have used high level math (read calculus). I went as far as Algebra II in school and that was over forty years ago. I have no chance of reading about DSP in the ARRL Handbook or Experimental Methods in RF Design and understanding these functions. How about a discussion of what these filters actually do for you and why you might want to use each one. Telling me IIR filters have feedback and FIR filters don't is good information but why do I care? What does each filter actually do for me and when should I use each one? Remember, no math and don't give me a source to go read about them unless that source doesn't use math in the explanation. --... ...-- Larry KB5DXY Don Wilhelm wrote: Lee, I do not know if it is 3rd grade level or not, but: Look at the ARRL Handbook chapter on DSP and Software Radio Design.

Re: [Elecraft] Question - for Educational Purposes
Lee: Since we are trying to stay at the 3rd grade level, I will spare you the mathematical definition of the difference. The observable difference is that if you apply a single pulse to the input of a Finite Impulse Response (FIR) filter, the output of the filter will be a finitely long train of non-zero pulses, but if you apply a single pulse to the input of an Infinite Impulse Response (IIR) filter, the output of the filter will be a train of non-zero pulses that never ends. After a settling time, the value of the remaining pulses will become very small, but they will never quite go to zero. The IIR response is akin to the time constant response of a linear analog circuit. (I could get into details like recursive versus non-recursive, but that is past 3rd grade level.) Advantage of the IIR filter: It is computationally cheaper than a FIR filter. In other words, if I want to obtain a specified filter response, an IIR filter will process the signal in fewer clock ticks than a FIR filter. Disadvantage of the IIR filter: It is susceptible to computational instability. In other words, unless you are extremely careful about both the design of the filter and the type of signal you apply to it, the filter output will gyrate wildly between the largest and smallest number that the machine precision allows; this is the machine's way of approximating a response that approaches infinity. Advantage of FIR filter: It is inherently stable. A bounded input must produce a bounded output. In most engineering applications the inherent stability is worth the cost of the extra clock ticks required for the FIR filter. 73, Steve Kercel AA4AK At 10:26 AM 7/24/2008, Lee Buller wrote: I've been doing some reading on the new firmware.

[Elecraft] K2 - keypad problem
Hi All, Im new to the group, I have a K1 #744 and just finished installing the KAT1 - Works great, what a rig ! So this is what I have I bought a K2 #4436 that was started by a ham who did not have the time to finish it. He managed to get to page 39 of assembly. When I bought the kit, I was not sure where he exactly left off, and so on So I went thru several procedures spending a couple hours checking his work, going through the resistance check sheet charts. All looked good. All three charts checked out to be fine. His work looked good. I continued building the kit and now I am stuck !I made it to page 42. Yes, a whopping 3 pages ! ;) Problem. Once the kit is turned on, 'Elecraft' shows up on the screen, then ' 204p 109 ' shows up for a brief second, the rig then displays the 7.100. I then press the display button - nothing, I try all the other front panel buttons, nothing. The main tuning dial does work and the display is fine. I went to the trouble shooting portion of the manual. I checked the voltage on MCU - the 5v that is required at pin 32 is 4.97. Thats fine. I listened for the 4 Mhz oscillator - its there, loud and clear. The rig does not display any INFO numbers - No smoke, Relays click in fine. Initial processor set up went fine too.

The very high design goals which we had set for the PT-8000 could be fulfilled in a few prototype units. 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.

Larry, The best way that I can think of is to encourage you to try both and draw your own conclusions of the merits of each. I cannot envision when *you* would want to use one over the other, my ear/brain combination will work differently than yours. Listen to both and decide. I would say that you would want to experiment under conditions of heavy QRM as well as heavy QRN or a combination of both - that is where such extreme narrow filtering would be effectively used - one cannot do a reasonable evaluation on an empty band. No math involved in that - just listen and let your own judgment provide your answer - it is a matter of perception, and each of us perceives differently, that is why you have a choice with the K3. 73, Don W3FPR.

Re: [Elecraft] K2 - keypad problem
Mike, You have a pushbutton that is 'stuck' for one reason or another. It may be a mechanical problem or it could be electrical. I am making that judgment because the display you report is exactly what is supposed to happen if you hold a pushbutton down while powering the K2 on - the fact that the pushbutton continues to be held down (either physically or electrically) results in the inability to do anything else. You can find out which switch in the pushbutton matrix is causing a problem using an ohmmeter. Check from front panel U3 pin 6 to each of U2 pins 3, 4, 5, 6, 11, 12, 13, and 14. If you find no path with low resistance, the problem switch is not in the Bank1 set, so check Bank 2 - check continuity from U3 pin 16 to the same pins on U2. If you find no pushbutton that is closed, check the soldering at RP1 carefully - these resistors act as pullups, and a missing pullup resistor in the circuit can act just like a closed pushbutton. As a double check, measure the resistance from each of the U2 pins mentioned above to the 5A voltage rail (U2 pin 16 is one location) - you should measure 100k ohms in all cases. 73, Don W3FPR Michael - VE3MKX wrote: Hi All, Im new to the group, I have a K1 #744 and just finished installing the KAT1 - Works great, what a rig !

Re: [Elecraft] Question - for Educational Purposes
Good explanation. Another advantage of the FIR filter is that it has flat group delay. That means the delay through the filter is independent of frequency, unlike in an IIR filter. Flat group delay results in less distortion of the modulation, which is an advantage for digital modes. It also makes analog SSB signals sound better. (Although you might not notice the difference since the signal also passes through the crystal filter which, like all analog filters, has an infinite inpulse response.) The infinite response of the IIR filter is usually not, in and of itself, a problem. Even an FIR filter has to have a long tail (ringing) in order to get a good shape factor. An FIR and IIR filter of the same bandwidth and shape factor will tend to have similar ringing characteristics out to the point where the FIR filter's ringing ends (and the IIR filter's ringing continues). But the ringing is often inaudible by that time anyway. Al N1AL On Thu, 2008-07-24 at 09:10, Stephen W.

Re: [Elecraft] Question - for Educational Purposes
2) The IIR filters have slightly steeper skirts, but ring more. The FIR filters ring less but are not quite as sharp. 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.

Re: [Elecraft] Question - for Educational Purposes
This discussion brings back memories of when I worked on FIR filter design many years ago, and I would add the following to the simple aspects that can be understood without math. The digital signal is of course a string of numbers representing samples from the analog waveform, just like the numbers coming off a music CD. The FIR filter works on some number N of the latest signal samples and uses all these N numbers to compute one output number. Then the oldest remembered number is dumped, and a new sample is entered, and the process repeats. Suppose there is a step change in the input samples. This will not reach its full impact on the output until the new sample level has propagated into all of the memorized samples that are used to compute the output. The FIR filter has a delay which is roughly the number N times the sample interval. However, it doesn't remember anything beyond this time span, as nothing except the past N samples can affect each output value. Now, suppose we change the computation of output samples so that this rule is broken. Just as an example, say that we use the N latest inputs as before, but also take the previous OUTPUT value into account when we compute the next output value. Now, that previous OUTPUT value is affected by at least one older input value, so the new output value is affected by more than N input values. This effect compounds, so that every output value theoretically is affected by all old input values. Thus an Impulse on the input keeps on infinitely affecting the output (theoretically). Hence Infinite Impulse Response. The flanks of a FIR bandpass filter get steeper with increasing number N of input samples used in the calculation of each output. This results in increasing delay. We just don't hear the other station immediately. Obviously there is a tradeoff between delay and selectivity. The other day a list member posted carefully measured selectivity curves of the K3 with various DSP filter widths and roofing filters (along with similar measurements on 1000MP). I just glanced over the graphs, but to me it looked like the K3 DSP filter flanks were far from brick wall in terms of shape factor; off the top of my head, the crystal filters may have been sharper than the DSP in terms of skirt falloff for a given bandwidth setting. This brings new light on the debate as to whether you really need those extra roofing filters. I am sure that the K3 designers made an intelligent decision as to the tradeoff between DSP passband shape and DSP delay. Does anyone know the number of N for the current FIR filters? I assume that the sampling frequency would be about 30 kHz for the 15 kHz IF frequency. Erik K7TV The infinite response of the IIR filter is usually not, in and of itself, a problem. Even an FIR filter has to have a long tail (ringing) in order to get a good shape factor. An FIR and IIR filter of the same bandwidth and shape factor will tend to have similar ringing characteristics out to the point where the FIR filter's ringing ends (and the IIR filter's ringing continues). But the ringing is often inaudible by that time anyway.

[Elecraft] [K3] MIC+LIN gain control suggestion
Talking to a friend about setting up audio inputs for his K3, I remembered this from the release notes: When MIC+LIN is in effect, rotating the MIC control shows MIC GAIN. The op has to set MIC SEL to LINE temporarily to set LINE IN gain. How about having the Mic knob toggle between MIC and LINE IN when MIC+LIN is selected? Set one of them, click the knob twice, then set the other one. It seems intuitive to me.

I sent an email to Wayne mentioning that I was having an issue that was very repeatable that resulted in the receiver being muted with no way to get out of it other than starting scanning again until it stops or power cycling the radio.

Re: [Elecraft] K3 Beta Release Update (MCU 2.20, DSP 1.88)
Hi, I just upgraded to 2.20/1.88 from 2.15/1.84 and find that the audio level on both line out and headphones dropped by almost 10dB (without making any changes to settings). The drop on the line out is a measured value using a VU meter app on the PC. This is for signal levels well above the AGC threshold which is set to the default of 5. I am not happy about this. I suppose I could compensate the headphone level by switching the AF gain from LO to HI, but why this *big* level difference just from fixing some obscure AGC bug? And surprises like this are really very unwelcome. I am sure that I am not the only one who has carefully adjusted recording levels on the computer only to find that things have changed dramatically.

RE: [Elecraft] Firmware Stability
Heck I think the scanning bug that I found had already been fixed when I mentioned it. Wayne actually mentioned that they'd been working on that and he emailed me code in VERY short order. But that was also a time in which Elecraft had made it clear they were excited about the scan feature and they wanted help testing it. I often find that asking for features in the area that the software engineer is currently working is a good way to get things moved to the top of the list. When a guy is in tight an intimate with a section of code you're more apt to get something fixed in that area of the project than if you ask about something totally different. It's all about being flexible. I mean honestly at this point in time (if you choose to) each and every one of us is working for the elecraft software test department. You don't have to as you can stick on a firmware that makes you happy and the rig operates to a level on par and better than most other radios on the market. You can stick and be satisfied or you can go with the flow and grow with it. Thankfully many are true elecrafters and are willing to grow with the rig. I'll admit I didn't get to grow up through the ranks of a K2. My first elecraft rig was a K1. But I can assure you I will be building a K2 someday... Talk about a radio that has become VASTLY more than what it was when it first hit the market! And the guys with very early K2 serial numbers can buy the upgraded boards at a reasonable price and get the upgrades. Granted I've got things about the K3 I want changed here and there but I've got no complaints at all. My problem is I work in this industry and understand what it takes to get this stuff done... Maybe my expectations are too realistic... -Original Message- From: hank k8dd [mailto:[EMAIL PROTECTED] Sent: Thursday, July 24, 2008 1:32 PM To: [EMAIL PROTECTED] Cc: Elecraft@mailman.qth.net Subject: Re: [Elecraft] Firmware Stability - Original Message - From: Brett Howard [EMAIL PROTECTED] Actually it wasn't too long ago that I was talking with Wayne when I'd had radio troubles and I'd mentioned that I wished there was a way to erase memories. He mentioned that he didn't understand why I'd want that when all I had to do was just write something else back over the top of it. Mainly its just cause I'm anal and like to have things clean and tidy Anyway he decided it was a relatively simple fix and poof it showed up. That was a fun one cause many other than myself appreciated that one. As well I had a slight problem in the way the scan feature worked. I sent an email to Wayne mentioning that I was having an issue that was very repeatable that resulted in the receiver being muted with no way to get out of it other than starting scanning again until it stops or power cycling the radio. There was a beta version of code that hadn't even been released yet that Wayne emailed me and poof my problem was solved. I always wondered how things got to the top of the wish list!

Re: [Elecraft] K3 Firmware 2.19

[Elecraft] K3 - FW 2.20 audio levels
Just installed 2.20 ... please disregard all of my previous comments regarding low audio levels for us deaf guys. I got the AGC fairly flat, found out higher thresholds seem to raise the point where AGC starts, thus things got markedly louder. After this I ran the AF gain at about 11 o'clock. Tried AF LO, gain is about 1 o'clock but no distortion at all. As far as Audio Levels go, I'm a happy ham ... well I'm a pretty happy ham in a lot of other respects too. I was messing around with the FIR/IIR thing and found that, listening to W1AW on 14047.5, narrowing the DSP bandwidth from 500 Hz to 150 Hz produces nearly no change in audio level. Going to 100 Hz, either FIR or IIR didn't matter, the audio level drops dramatically, and stays there at 50 Hz too. I'm pretty sure I've missed a detail here. I don't run at 100 Hz hardly at all so it isn't really going to affect me, just curious. Regarding ringing of IIR filters, I understand the math [math and engr degrees], but honestly, I don't hear much difference at 100 Hz BW between the finite and the infinite [never thought I'd find a way to use them in the same sentence]. W1AW sounds about the same, and there is almost no ringing. It sounds a little peaked to me, but then again, without my hearing aids, everything sounds peaked at about 600 Hz. Hope to hear lots of Elecrafters in the Flight of the Bumblebees this Sunday. I'm a Bee, I'll be on with my K2, BuddiPole 20m vertical GP, and solar charged gel cell. I may have one of W6MMA's yagi's and if so I should be 5NN for you :-) 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 Firmware 2.19
Gee, I don't know To only say the audio went up, or down, when I loaded X.xx doesn't tell me anything! What was the AGC SLP? AGC THR? NR settings? With out that information, yes - it can go up or it can go down when you turn NR on! I just loaded 2.20. The audio went way up when I turned on NR - I was using the XG2, 50 uV on 80M. SLP= 4, THR= 8 NR= F2-2 and I had really liked the way the radio sounded with the 2.1x's, but with FW 2.20, NR would hurt it was so loud. Almost triple while monitoring AFv. Changing SLP = 14, THR = 5 got the audio real close . but the radio sounds like crap. OK . that's a personal observation of what it sounds like to me on 80 CW! I'm not sure I understand everything I have read about SLP and THR! Nor do I want to. I want a radio that sounds close to or better than the K2!

[Elecraft] K2 VFO Linearization Problem
K2 #3766, a kit that I bought a few years ago and let sit on the shelf for a while. I'm finally threatening to finish it. All has gone well up to the VFO Linearization step in Alignment where the CAL PLL menu item is supposed to be run. I've followed the instructions to the letter, but when I go through the menu, select CAL PLL and hold the EDIT key to start the linearization sequence nothing. The 12099 kHz frequency is displayed, but does not change. There are no ds displayed to indicate stored data points. Nothing happens. Any ideas? MCM firmware is 2.03.

[Elecraft] K#: 2.20 / 1.88
Hi Everyone I just loaded Beta 2.20/1.88. IMO the AGC is now virtually PERFECT. (I was actually expecting to be disappointed with it. Absolutely the opposite.) Running my SLP at 7 and THR at 6. I may run it at SLP 8 and THR 5. I'm not sure yet. The linearity of the new SLP function works very well. My AF is on high range and running at 9 O'clock position. The NR audio level seems much improved and balanced between engaged and not engaged, perhaps even a little too loud with NR engaged. I like it. Elecraft, your radio and your support is amazing. I hope that you are having as much fun in your work as I am in playing with your results. My $.02. I realize that others may not feel the same about Beta 2.20. You should try experimenting with the AGC SLP and THR settings to see how they change how various signals sound from the receiver. 73 de N1LQ-Dave ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

In CW mode I see 8db of audio gain with NR engaged. In SSB, a reduction (not measured). It depends on what is being processed.

Re: [Elecraft] K#: 2.20 / 1.88
That's ok...it's good to check to see if I am nuts or not. hi hi Yes, listening to SSB on 20m this evening and actually there is not much noise on the band, for a change. Listening to several QSOs and turning the NR on causes a drop in audio...but then again, it always has. I haven't tried it on CW.

Re: [Elecraft] K#: 2.20 / 1.88
Yea ok then.. I found that mine usually resulted in a reduction of audio but depending on the band and conditions sometimes it was the same and sometimes it was more. I think that this difference in amplitude depending on the conditions and NR settings selected makes matching the level pretty near impossible. But thankfully there is an AF knob that allows me to do so quickly and easily... :) I'll have the K3 back tomorrow and I'll be upgrading to the latest beta... Not sure what is going on this weekend but hopefully it'll be a good chance for me to play...

Re: [Elecraft] K3 V2.20/1..88
Yes I did. I wound up with SLP set to 8 and Threshold at 5. I just changed the threshold setting to 6 and I think it made some difference. The audio with NR on is considerably louder than with previous versions of the firmware. I can really tell a difference on CW. So I think I'm ok. I had an adjacent signal just below where I was listening and with the threshold set to 5 it may have been causing a little more pumping that was causing the AGC to reduce the audio a little. Actually I'm not sure if the lower setting of the threshold creates a stronger AGC action or not. Listening to some different signals around the band revealed that I do have a little more audio with the NR on than I did with past versions of the firmware.

I've been a chicken for several weeks waiting till things went into production. 2.02 to 2.20 is a lot of updates to the firmware. I got tired of waiting. Everything went hunkydory. Set the SLP at 8 and Threshold at 6 and works great! The NR button works differently now The weak signal pops up out of the noise (the noise is abated) and I can copy the station. I am listen on 40 CW. Adjusting the Noise Reduction parameters even help farther. There is not reduction of audiobut the signal just pops out. Great job for Elecraft.

Re: [Elecraft] K3 V2.20/1..88
Stan, My unmeasured ears tell me that when NR is engaged, the overall audio sound of the desired SSB signal stays about the same, but the overall audio is reduced because the noise is not longer present. Maybe my ears are different than yours, but that is what I am hearing. 73, Don W3FPR Stan Rife wrote: Wow, I really must have something set differently than everyone else.

[Elecraft] K3 :: slightly reduced TX output power at 100W setting
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.
