Hi,
I put my K2 #1400 back on line last night to have a listen around 40M CW. I'm getting a bit fed up with one step forward, half a step back firmware upgrades and am giving it a rest for a while. Anyway, I was surprised just how nice it sounded compared to my K3. The audio seems softer and warmer somehow. Same bandwidth (400Hz), same phones. The K3 background noise just sounded harder, more harsh. I've had this feeling from day one.

Hi Mike,
It's funny you should post at this time. I don't have a K3 but, I was looking at the test results on the Elecraft web site just yesterday. I was wondering how much difference there really is since the numbers are pretty close.

Firmware Fatigue - was K2 v K3

In reply to this post by Mike Harris-9
Mike.... I too am somewhat dismayed with the firmware issues surrounding the K3. I love the k3, but it seems that something is added the new firmware breaks something else. I think that it is just going to take time to bring it all together. Elecraft says they are not programming to the "niche" players but they seem to be quite vocal in their desire for features in the K3. The old addage, "the squeaky wheel gets the grease" comes to mind. Reading the list serv tends to make me a little piqued from the stand point that there are so many "niche" requests. I do not care about ESSB or AM or bouncing signals off the Moon or working VHF contests in Europe. Oh, those are all fun things to do, but I think it just becomes overwhelming to the user and to the programmers. In time it will get there but give me basic functionality that works as a world class transceiver. And that is something that we should all remember....in time the firmware will get there. In a year from now, the firmware will be mature and all this should be behind us. It just is going to take time. The K3 development is a work in progress and the users are providing valuable data to the engineering team to make the K3 the world class transceiver it is designed to be. We just have to wait for the firmware to mature. Thanks Elecraft for a great product and listening to all of us. Lee - K0WA In our day and age it seems that Common Sense is in short supply. If you don't have any Common Sense - get some Common Sense and use it. If you can't find any Common Sense, ask for help from somebody who has some Common Sense.

Gary the numbers might be close at 5 kHz but the K2 (I have #4119) badly falls apart at less than 5 kHz spacings. I remember the first time I tried using mine versus my Orion on 160m and it was a HUGE disappointment. I was listening to an extremely weak YA8G on 1814.0 and could not believe my ears when I began to hear W1AW code practice on 1817.5 leaking through from 3.5 kHz away. Check out the closer spaced test results by independent testers like Sherwood and ARRL. Sherwood's IMD results at 2 kHz: K2 S/N 1140 - 70 dB K2 S/N 3170 - 80 dB K3 (S/N in the 100s) - 95 to 101 dB (depending on XFIL) http://www.sherweng.com/table.html The K2 is a great little rig but it's frankly out of its league when you start prowling 160 for weak signals in the presence of very strong local signals. 73, Bill W4ZV |

As a prospective purchaser, I've been following the list with interest,
especially the discussion of various issues related to the firmware. 1. Maybe there needs to be a step between the beta testers and a general release. That is, a Release Candidate version (or versions, rc1, rc2, etc). For the adventuresome, bleeding edge, or just those who want to help the process, without being a formal beta tester. 2. Maybe the development path could fork into bug-fix and new features branches. I could be wrong here, since I'm just going by the comments, but it seems that new firmware introduces both fixes for known problems and extensions of capabilities. Having a stable branch (bug-fixes only) and an unstable branch (new features) would allow those who are happy with current features to get improved firmware without running the risks associated with new, less-well-tested, features. 73, Dave KQ3T _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

One thing that so often amazes me when reading forums like this is the intolerance of so many hams towards radio activities that they personally are not interested in. You may not care about ESSB or AM or bouncing signals off the Moon or working VHF contests in Europe, and they are not activities that I personally engage in either, but for some people these are their main interests in the hobby. They are just as entitled to express their wishes and have them listened to as any other. The money they paid for their K3s is just as good as anyone else's. I'm quite sure Elecraft is capable of prioritizing the requests for features. I know they are - there are a few things I've asked for that I'm still waiting for.

I find myself going back to my K2's, just to see if there is any instance where my K3 out performs my K2's, and I, like you find the K2's much easier to listen to. Yes, the K3 has a lot of neat features, data modes, rtty modes, etc, but when it comes down to digging them out of the mud, the K2 is as good. No, the K2 will never be the SSB rig the K3 is, nor will it do FM/AM etc., but for CW, it's right there with the best. I can understand why some people don't like the K2's size and small knobs. Fortunately I have small hands. The K2 is a great qrp contest radio. I think it was 2003 SSCW where I ran my K2's in a SO2R configuration, QRP. I finished 2nd overall, losing to N6TR, who decided to run QRP that year. I contribute that to good luck and the K2's. I'm not knocking the K3, not at all. But if someone is wishing for a K3, but can only afford a K2, or 2 K2's (at the price of a loaded K3), get a K2, you won't regret it. Yes, my K2's sound warmer than the K3. Maybe it's the way the filters are adjusted? One thing the K3 did do for me, it made me realize what a truly great radio the K2 is!

I think the problem (well, one of the problems; there are several) is that they don't, in reality, have a "Beta" test; they go from "Alpha" right into Production. 73, Steve On 5/7/08, Dave KQ3T <[hidden email]> wrote: > As a prospective purchaser, I've been following the list with interest, > especially the discussion of various issues related to the firmware. > > 1.

Hi Bill,
That's a good point. I guess I didn't really think about that since I've rarely noticed it. Both of my other HF rigs are from the 80's and my K2 #6113 is the newest that I have. I'm use to fighting QRM. Hi! Hi! To me, the K2 is way better than my other rigs. Now it makes me wonder what I'm missing or perhaps I should say, not missing, when it comes to QRM. I love to work weak signals and QRP. I did own Ten Tec rig with DSP for a short time and then sold it before buying my K2. I didn't like the DSP. If I had a radio that made it easier, I might get bored with ham radio. I keep looking at the K3 but, that little voice inside keeps telling me to wait. I'm not sure why. I'm widowed, I have not children, I can afford it, and if my xyl were still here, she would tell me to get it. I think I've become my own worse enemy! Hi!

I am an outsider, just an Elecraft customer, and from what I've seen there is nothing wrong with their development process. User/Field flashable devices are more toward the personal computer software release style, than what we are use to for black box amateur transceivers. The firmware upgrade process for the K3 is no harder than frequency calibration, so I don't particularly see why there is so much concern. Maybe I'm missing something because I'm extremely comfortable for computers. Of course, I personally view and can visualize software as an extension to hardware (analog and digital) so I just see it as a different point on the continuum of change. Not unlike the general decline (and popular demise) of electron tubes and analog computers. Heck you don't even have set down your drink to update the firmware, whereas some of the post initial release K2 mods were best done with two hands which could interrupt beverage consumption.

There is nothing to be dismayed about.....
When you have complex software development, upgrades, and patches, this requires extensive software REGRESSION TESTING, in order to determine what other existing functions or features may have been affected or impacted from the new code release. This is normal, normal, stuff. This is a very unusual situation whereas the manufacturer has given the customer base (via reflectors) such a large amount of visibility into the development process. Any anomalies observed should be reported to the Elecraft team, so that they can prioritize the issues as well as determine which ones are real or not. -----Original Message----- From: [hidden email] [mailto:[hidden email]]On Behalf Of Lee Buller Sent: Wednesday, May 07, 2008 9:26 AM To: Mike Harris; Elecraft Reflector Subject: [Elecraft] Firmware Fatigue - was K2 v K3 Mike....

Mike,
I believe it is all in the perception. The K2 is all analog (unless the KDSP2 is active), but the K3 processing is digital. Each has its own advantages and artifacts to contend with. Analog can soften the background noise while the digital DSP can reproduce it 'in all its glory'. I equate this perception to the folks in the audiophile world who claim that vacuum tube amplifiers are better because they are 'warmer'. Actual measurement will show that solid state amplifiers can better duplicate the input waveform while vacuum tube gear adds 2nd and 3rd harmonic distortion to the output. To each his own. Remember that perception is 99% of reality. 73, Don W3FPR Mike Harris wrote: > Hi, > > I put my K2 #1400 back on line last night to have a listen around 40M CW. > I'm getting a bit fed up with one step forward, half a step back firmware > upgrades and am giving it a rest for a while.

No problem here Wayne, I remember when a mod required a hot soldering Iron
to undo. And in case any of the younger crowd here thinks this wasn't a big deal should have owned the hotest rig for 1978, the Yaesu FT901DM. It kept a monthly newsletter full of mods (Fox Tango Club, before internet e-mail) and they didn't always work, and the hardware was not returnable. The one I'm reminded of most from those days was tearing into the audio card to modify the mic amp front end. Most of us hated the tinny high pitched mic audio the Japanese built into those rigs. A few caps and resistors later it sounded a little better. That one mod took more time to get right than ALL the FW upgrades I've done on my K3 since Last November.

Don,
Perhaps you have suggested one possible solution to making the output from DSP sound less harsh ('yucky' is a better term IMHO), add some harmonics of the desired output signal. I can't at the moment see how this could be done with relatively simple circuitry which would have to distinguish between the desired output signal and any unwanted artifacts at the DSP's output, and not introduce any additional undesired artifacts. Just a thought not aimed at any particular radio which uses DSP. 73, Geoff GM4ESD Don Wilhelm wrote: > Mike, > > I believe it is all in the perception.
