After an Orion, O2–now 2 K3’s, I want an O3!

See no possibility of anO3.

The K3 is a super radio until one hears clicking in earphones while running 7QP in full breakin.

That was not a factor in the O’s.

For those of us with bigger hands/fingers the K3 is not optimum. Also too many menus.

Nothing on the present market suits me, though the K3 is on my desk.

Make a K4 bigger with many fewer menus. I am not interested in hauling my radio around the world, so bigger suits me just fine.

Add solid state keying to reduce clicking especially in earphones.

I am a CW op. Give me an optimized CW rig with FSK and for others SSB.

This stubbornness, I suspect, was born out of a sense of technological arrogance. In the early 1970s, the Swiss watch industry, enamored with their mechanical movements, refused to embrace quartz technology. That decision would result in decades of rapidly declining Swiss watch sales. The ultimate irony is that today many Swiss watches make use of Citizen internal movements. Conversely, there are companies like Apple. Apple, was able to leverage existing technologies and make them ?better? for their end-customer. In other words, confront the paradigm shift head-on, know what your end-customers will most value (even if they don?t know it today) and positively exploit the emerging technologies. Elecraft is more of an Apple than it is a Swiss watch company. I have no doubt they will positively exploit emerging technologies and deliver products with features that we haven?t even thought about today. Have faith, all. And, by the way, as we wait, we?ll just "have to live with" our worldclass transceivers; not a bad position to be in if you ask me. 73, Joe W1GO>On May 5, 2019, at 12:41 PM, Drew AF2Z wrote:>>I've never doubted that Elecraft would produce a great CW rig, if not the best!>>The only thing I'd be concerned about is the operator interface.

So if you need a stronger signal just tune your Siglent to 1/3 of 50 mHz which is 16.6666 etc mHz. The third (and 5th, 7th, etc ) harmonics should be plenty strong. You may need to crank your Siglent up a bit to get the desired diode action. In theory this idea should work.

The trick would be to use "real" controls for things you do most often, and make sparing use of touch for basic operation. Of course touch has some cool aspects like tap/drag, pinch/spread, etc., that can be applied to new features such as an advanced panadapter.>>I think modern rigs could benefit by having an optional keyboard interface-- no need of an intermediary computer, just a dedicated plug-in (or wireless) keyboard that could be used to access all the rig controls and menu items.

We're dedicated to providing gear that won't break your back, runs efficiently, and can be used for portable applications when needed (Field Day, DXpeditions, emcomm, RV, etc.). A new radio would have be somewhat bigger to accommodate a large display, but it would not have to be twice as large, weigh 2 to 3 times as much, or consume 3 to 4 times as much power as a K3S. All of the K3S's newer competitors have one or more of these non-portable characteristics, and some have all three. 73, Wayne N6KR ------------------------------ Message: 12 Date: Sun, 5 May 2019 10:27:25 -0700 From: Wes To: [hidden email] Subject: Re: [Elecraft] Prospective K4 Message-ID:<[hidden email]>Content-Type: text/plain; charset=utf-8; format=flowed How are you liking the radio performance wise??

It's probably clear to many, but not me. :-) I think of 'channel' as the RF channel, but this is used differently. A demod channel as opposed to what other sorts of channels? Also, since an fft/ifft change over between frequency and time is the norm in SDRs, why does it matter at what point processing is performed? Not doubting, wanting to understand. Tnx es 73.

SDRs (using wideband direct sampling and no crystal filters) process all incoming receive samples in large packets.This provides some economies of scale for signal processing algorithms, but it does impact latency. In some cases the impact can be dramatic ? like 100 to 200 ms QSK delays. An alternative is to process only the pan adapter data in large packets. If such data is only being used for a spectral display, the latency is not an issue. In CW mode or in other situations where latency must be low, time-domain DSP routines can optionally be used for processing data from the slices (signal channels) used for demodulation. Latency as low as just a few milliseconds is then possible, contingent on the level of filtering required. Filtering trade offs can be automated, e.g. in proportion to the QSK delay setting.

Istv?n To: [hidden email] Subject: Re: [Elecraft] Prospective K4 Message-ID: Content-Type: text/plain; charset=utf-8; format=flowed Many HAMs use transceiver with language barrier. That goes so far that they use it with one setup, that might be the wrong one for a given frequency or antenna or mode. With Windows they choose their own language when they set up the PC to make the life easier. That may not work every time, like my case I could not set up Fldigi on Hungarian keyboard PC though W10 was English. So moved to a second PC. With SDR trx that option will never happen so they insist on simple radios, asking for manual translation.... For those a very simple menu system is welcome. K3 is a good, keep that practice, no multilevel menus are received well. Complicated SDR is not for them.

Not really looking forward to touchscreen controls here, though I suppose they are inevitable in modern rigs.Touch/mouse would provide a lot of flexibility. The trick would be to use "real" controls for things you do most often, and make sparing use of touch for basic operation. Of course touch has some cool aspects? like tap/drag, pinch/spread, etc., that can be applied to new features such as an advanced panadapter.>>I think modern rigs could benefit by having an optional keyboard interface-- no need of an intermediary computer, just a dedicated plug-in (or wireless) keybo ard that could be used to access all the rig controls and menu items.Definitely.>I wonder if Elecraft will stick with the high portability/low power consumption design. Those things aren't really important to me. I wouldn't mind a larger rig.We're dedicated to providing gear that won't break your back, runs efficiently, and can be used for portable applications when needed (Field Day, DXpeditions, emcomm, RV, etc.). A new radio would have be somewhat bigger to accommodate a large display, but it would not have to be twice as large, weigh 2 to 3 times as much, or consume 3 to 4 times as much power as a K3S. All of the K3S's newer competitors have one or more of these non-portable characteristics, and some have all three.73,WayneN6KR______________________________________________________________Elecraft mailing listHome: http://mailman.qth.net/mailman/listinfo/elecraftHelp: http://mailman.qth.net/mmfaq.htmPost: mailto:[hidden email] list hosted by: http://www.qsl .netPlease help support this email list: http://www.qsl.net/donate.html ------------------------------ Message: 21 Date: Sun, 5 May 2019 19:34:45 +0000 (UTC) From: Eric Lanzl To: Elecraft List Subject: [Elecraft] Elecraft SSB Net for Sunday April 28-2019 Message-ID:<[hidden email]>Content-Type: text/plain; charset=UTF-8 Here is the list of stations from the net last Sunday.

W6JTI and I just ran 18 hours of 7QP with full QSK and no clicks. Two
stations with a K3, KPA500, and KAT500. One station also had P3/SVGA.
N7N activated six NV counties, making 2,200 QSOs. About 350 were SSB.
You should investigate what might be causing you to hear clicks. Perhaps
in your station or outside your station, like passive intermod.
