Re: [Elecraft] Expect delays in our responses to K3 questions for awhile
A couple of questions I didn't see answered there (perhaps I missed them) are: - what type are the antenna connectors (look like SO239's in the rear view on the data sheet) - what protocol does the radio's RS-232 control use? (I'm guessing it will have a lot of unique commands, but if it can be used with something like the Kenwood protocol, like the K2, that will be a big help until the various CAT programs add full K3 support.) I'm also intrigued by the idea of computerless datamodes operation using a small external keyboard instead of a CW paddle. Will that be a future kit? I'm totally gobsmacked by the K3. I never imagined that the K3 people have fantasized over for years on this reflector would actually become a reality, in kit form too, at such a reasonable price. The moment I saw this, as when I first read about the K2 back in 1999, I knew this was one radio I just had to have. From this side of the Atlantic, at $2 / £1 exchange rate, it looks very good value indeed. I'm hoping that the modular kit will qualify for import duty exemtion as well. I have decided to get my order in before one of the UK dealers asks for exclusive UK distribution rights and we all end up having to pay twice the price.

[Elecraft] AGC Pumping - NOT an issue in Orion or K3(?)
Regarding comments by W3FPR and N6KR below. I've been thinking about this and wondering why I have never heard this in my Orion in nearly 4 years. I've operated in many contests, including the CQ 160 CW every year with only an Inrad #762 4-pole 600 Hz roofing filter. This environment is far worse than virtually any other situation you are likely to encounter, typically with S9+++ signals spaced every 500 Hz. I have *never* heard classical AGC pumping, which sounds like the noise floor is being modulating up and down in a normal rig. From an RF front-end standpoint, the K3 is a virtual clone of Orion. Both are down-conversion (8.2 MHz first IF versus 9.0 MHz) followed by narrow roofing filters. Both DSP stages (2nd IF in K3 and 3rd IF in Orion) are protected from over-driving by an analog AGC which activates at approximately S9+30 (not sure of the exact point for K3). This prevents the DSP stage from going into fibrillation (over-driving) which sounds like machine gun fire beside your ears...nothing like classical analog AGC pumping. Assuming signals entering the DSP are not over-driving it (i.e. less than S9+30 dB or -43 dBm using the classical definition of S9 = -73 dBm = 50 uV), the DSP creates a filter around the signal of interest. According to Doug Smith (original architect of Ten-Tec Orion), the DSP stage has approximately 100 dB of dynamic range (reference below). As the resolution and speed of ADC hardware improve, digital radio receivers become less dependent on analog AGC to meet dynamic-range requirements. State-of-the-art 24-bit IF-DSP converters, such as those used in the Ten-Tec Orion, produce about 100 dB of dynamic range. That means a receiver can handle signals from the noise floor to almost 40 dB over S9 without analog AGC. Above that level, analog AGC is still necessary to maintain the linearity of analog circuits and to prevent overload in the ADC hardware. http://www.doug-smith.net/dspdynamics.htm Assuming I have a very strong interfering signal (less than S9+30 which is controlled by the analog AGC limit), the DSP filter should be able to eliminate it without any AGC pumping. I repeat from Doug Smith above: That means a receiver can handle signals from the noise floor to almost 40 dB over S9 without analog AGC. Assuming S9+29dB = -42 dBm, subtracting 100 dB for the dynamic range of the DSP, the result is -142 dBm, which is well below the noise floor. To me this explains why I have *never* heard AGC pumping in Orion...hopefully K3 is the same! 73, Bill W4ZV W3FPR: AGC pumping is the problem I notice most with data modes - the roofing filter must keep out of passband signals at a sufficiently low level to allow copy of a weak desired signal. Also my opinion on filters used for data modes is that they would ideally have good group delay characteristics, and to me that is more important than steep skirts or a flat passband. (steep skirted filters with very flat passbands usually exhibit poor group delay characteristics). Low group delay also means more pleasant sounding CW. Steep skirts are not really needed with a roofing filter because the DSP can create the desired skirt selectivity. Again the roofing filter must only be narrow enough to keep strong offending signals out of the 1st IF passband (or sufficiently reduced to keep the AGC pumping problem at bay). Perhaps a Gaussian to 6dB filter would act as a better roofing filter than a steep skirted filter - but I have not done any measurements - just thinking out loud. 73, Don W3FPR wayne burdick wrote: Let's suppose the only crystal roofing filter you have installed is 2.8 kHz wide. You put the rig into CW (or data) mode, then dial the DSP bandwidth down to 400 Hz. Everything will be fine -- unless an extremely strong signal appears that's *outside* the DSP's passband but still *inside* the crystal filter passband. This can cause what's called pumping, meaning activation of the AGC or desensing. Many transceivers with I.F. DSP don't have the ability to do anything about this, so they get trashed on receive. Such transceivers typically have only a 3 kHz (or wider) roofing filter, allowing strong signals to cause trouble. The K3 has roofing filter bandwidths as low as 200 Hz, giving you a means to completely eliminating problems with nearby signals. If installed, these will be automatically selected as you narrow the DSP's bandwidth using the shift/width/hicut/locut controls. Or you can select them manually. We'll add this to the FAQ. 73, Wayne N6KR ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

Re: [Elecraft] KUSB for K3
Don Wilhelm wrote, regarding USB to Serial Adapters: Yes, there are a lot of USB adapters on the market at a wide variety of prices, but it seems not all are equal. Review the number of questions related to 'will adapter XXX work with YYY'. With the offering by Elecraft, there can be no doubt that it will work with the Elecraft K3. Will other adapters work? Maybe, but we *DO* know the answer for the Elecraft adapter - no guessing. I have a Tripp-Lite U-209-000-R adapter which WORKS GREAT.. BUT... it does NOT want to be peroperly detected, and drivers auto-loaded, if it's plugged into the USB port when the PC is booted up! If it's left plugged in when the PCs booted, the OS (WinXP Pro in my case) wants to re-install the drivers EVERY TIME! If I UNplug the adapter, boot the PC, and THEN plug the adapter in, WinXP finds and installed it with no complaints. I'm posting this as a word of caution to those who might be considering a Tripp-Lite adapter. I'm not certain if this is a problem unique to WinXP or not. It seems to be a problem with regard to 'order of installation' of the device drivers, with the adapter drivers not being installed in time for the adapter to have been detected... OR with them being installed too early to have been of use. 73, Tom N0SS ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] KUSB for K3
Interestingly, this this of problem is created for Windows. There are a limited number of USB/RS232 converter chip types in the world, all supportable by a small number of drivers. Each seller, though, gets to set an id in the chiop, which tells the OS what driver to load. The RS232/serial bump-in-the-cord devices could all get by with the same driver for the same chip if this number weren't changed. So, why does this number exist? Partly yo allow manufacturers of hardware to make it look like there's something special about their devices by adding features in the driver, but mainly to accomodate automatic detection of devices that directly incorporate these chips and offer some other functionality (I.e. other than the generic converters). Devices such as cameras generally have their own protocols and don't use the generic serial chips, but there are indeed some devices out there that use this ID to make a useful driver load. The price we have to pay on Windows is getting a new driver for each one, and suffering from needlessly buggy copies of the code as Tom has reported. If the K3 had its own internal chip with its own ID, there would be an opportunity to have Windows auto-launch an application (Ham Radio Deluxe? N1MM Logger?) whenever it detected the special K3 ID. There isn't much advantage to this, and it would require, because of the way Windows works, a special driver. On Linux, the RS232 coverter generic drivers work fine for the USB-Serial devices, but you don't get the automatic application launch that you can get with Windows, although it is possible to configure it for some the special devices. The problems with them come mostly in the cases where they really are closer TTL instead of RS232 and the keying circuit depends on the negative swing, or the supply isn't stiff enough to meet the signalling device needs (both problems on Windows as well). Of course, Linux suffers as well from the need to have unique driver (or more likely application) support for devices that directly incorporate these chips and offer some functionality other than just serial conversion. 73, Leigh/WA5ZNU On Sun, 6 May 2007 8:51 am, Tom Hammond wrote: Don Wilhelm wrote, regarding USB to Serial If it's left plugged in when the PCs booted, the OS (WinXP Pro in my case) wants to re-install the drivers EVERY TIME! ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3, full duplex satellite operation, XV-144/432 packaging
Hi all, I'm been mulling this over (mostly while riding my bicycle). It looks to me as if the IF freguency for the XV144 or the XV432 can be changed pretty easily. If this is done, then full-duplex using the K3 would become a bit easier. If the firmware for the K3 would allow transverter operation on 28 through 32MHz and some other reasonable IF (22-24 MHz?(I have no idea what would really be right)), then we could use the K3 for full-duplex satellite operation. And if a repackaging job could be done to combine these two units in a single package, then a lot of external cabling might be disposed of, and it might be made to match the K3. 73, doug ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Now I have more than double the power out with no increase in weight, no decrease in operating time and I still have an integrated package.

[Elecraft] AGC, Dynamic Range, 200 Hz Roofing Filters, etc
From my previous post: As the resolution and speed of ADC hardware improve, digital radio receivers become less dependent on analog AGC to meet dynamic-range requirements. State-of-the-art 24-bit IF-DSP converters, such as those used in the Ten-Tec Orion, produce about 100 dB of dynamic range. That means a receiver can handle signals from the noise floor to almost 40 dB over S9 without analog AGC. Above that level, analog AGC is still necessary to maintain the linearity of analog circuits and to prevent overload in the ADC hardware. http://www.doug-smith.net/dspdynamics.htm Is 100 dB AGC dynamic range enough? Generally yes, even though this range can be extended to 140 dB if very strong signals activate the Analog AGC protection ahead of the DSP's Digital AGC. Here are some real-world measurements on 160m by W8JI: http://www.w8ji.com/receiving.htm The strongest signal measured was -32 dBm above the noise floor of -127 dBm, which resulted in a needed dynamic range of 95 dB, well within the capability of the ~100 dB Digital AGC dynamic range inside the DSP (without any need for Analog AGC protection, assuming the operator properly positioned the lower limit of the receiver using attenuation). Why might the actual range needed in a contest be less? Because the above quiet band noise floor of -127 dBm will be significantly raised by key clicks and transmitted phase noise from many less than perfect signals. This is why it becomes somewhat academic to pursue extremely high IMD performance at very close spacings using roofing filters much less than about 500 Hz bandwidth. At spacings 500 Hz, the noise floor rises dramatically due to transmitted phase noise and key clicks. Let's assume a 200 Hz roofing filter gives you 95 dB IMD performance at 200 Hz signal spacings. This would put an interfering signal well outside the +/- 100 Hz pass band of a 200 Hz roofing filter. Even for the cleanest rig available today (Orion) in terms of keyed CW waveform and phase noise, transmitted noise will be in the ballpark of only 30-40 dB down at 200 Hz from the carrier (an optimistic assumption). Thus the 95 dB you thought you bought with your 200 Hz roofing filter is totally obliterated by the adjacent transmitted signal, and you can do *absolutely nothing* in your receiver to eliminate it. The SDR-X may hold some future promise of help but Orion or K3 cannot. It may make some feel good to buy such filters, but in the real world of imperfect transmitted signals, it really doesn't do us much good as far as improving the dynamic range we'll actually experience. Using steady-stage (unkeyed) crystal oscillators (with exceptional phase noise) in a laboratory setting to get exceptional IMD results may make us feel good, but in the real world of transmitter key clicks and synthesizer phase noise it actually makes little if any difference. Of course I realize some will still buy such filters, but quite frankly it reminds me of audiophile or Citizens Band arguments for things like gold-plated speaker wire and microphones. :-) 73, Bill W4ZV P.S. My guess for the K3's dynamic range specs are: BDR at 2 kHz - 143 dB (Wayne already gave us the answer!) IMD at 2 kHz - 95 dB (equal to Orion - possibly a little better) Digital AGC - 100 dB (similar to Orion if both use 24-bit ADCs) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] New Remote Mic Header Aftermarket K2 Accessory
We have designed another Rework Eliminator(TM) K2 accessory. Our latest offering is a K2 Remote Mic Header assembly. It consists of two tiny four-layer PCBs which fit between the K2's Front Panel and Control circuit boards. As with our un-module header kit, this new product also eliminates the need for substantial disassembly of the K2 enclosure. Once it's installed reconfiguring your K2 for any of the microphone wiring standards described in the KSB2 manual can be accomplished in a few seconds after removing the K2's left side panel. For technical details including a User's Guide, preliminary assembly and installation instructions, and some 1,000 DPI CAD renderings, please see http://www.unpcbs.com/micpcb/. (The User's Guide includes a growing list of Frequently Asked Questions.) We've not yet determined the cost to produce this kit so we can only guess as to what the retail price will be. In addition, volume will be a contributing factor affecting the price since there are fixed costs associated with PCB production. Presently we just need to know if there's a sufficient demand for this accessory to warrant producing it. If you are interested, please indicate so by voting in our latest unpcbs Yahoo Group poll at http://groups.yahoo.com/group/unpcbs/. (You will need to join the group to register your vote.) This is still very much a work in progress so we welcome your comments, suggestions, and criticisms. Thank you for your interest.

Re: [Elecraft] Digital advice sought for K2 and K3
Tony, As I understand the K3 you won't even need the RigBlaster, it can connect directly to the computer (only cables and plugs needed) - even does RTTY/PSK31 without the computer at all if you want. For the K2, you should provide some isolation between the computer and the K2 - transformers in the audio-out and mic-in do that job and a voltage divider is needed in the mic input because the soundcard output is much greater than the mic input level.

RE: [Elecraft] Digital advice sought for K2 and K3
Tony, I'm using a RigExpert S/D with my K2/100. Currently with just the SPKR and MIC connections for audio (which is messy), and hopefully using the MiniDIN on the BLQ interface as of sometime this week (thanks Doug !) - just to make for simpler cabling. The RE is nice, small, and USB-based. That's good for laptops that no longer have a (real) serial port. It also implements its own sound card, _and_ it presents a CAT serial port to the various HAM programs. Meaning: - one cable between that box and the K2 for audio/ptt (MiniDIN, or the MIC/SPK setup) - one cable between them for CAT (to the RS-232 port on the K2) - one cable between the box and the PC (USB) That is all. I use it with HAM Radio Deluxe, MixW2 and EchoLink.

Re: [Elecraft] Digital advice sought for K2 and K3
You might consider getting the RS232 K2IO interface and using it for keying, instead of using PTT. With the K2IO, you can use rig control via RS232 commands with many digimode programs, which can also use the RS232 to bring frequency, modes, filters, etc. settings to your computer. Having an accurate frequency display (VFO +/- AF, depending on sideband) helps. 73, Leigh/WA5ZNU ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 and linear amplifiers
QSK requires that an outboard linear is somehow switched into transmit mode, preferably before RF arrives at its input socket. In the case of my TenTec Hercules II amp, a control signal is fed back to my Omni-V to tell it the linear is ready to receive RF drive. The Hercules uses a vacuum relay; there are fast and slow QSK options built into the Omni-V. Will the K3 accommodate this kind of interlocking ? ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] Ethernet Interface for K3 (Was: KUSB for K3)
Personally, I would dearly love to see Elecraft offer an Ethernet/IP interface for the K3. That would be sufficiently fast that we could not only send commands and get status, but we can also send/receive audio or other modulations as well. I would dearly love to see various digital modulation/demodulation modes built into the DSP; e.g. BPSK, QPSK, QAM, MSK, FSK, OFDM, baseband audio, etc. Let me send a UDP packet filled with bits to the K3 and have the DSP in the K3 modulate and transmit. Likewise I would like the received bits demodulated and dumped into a UDP packet to be sent wherever I want those bits. This would turn the K3 into a full-on SDR (within the bandwidth limits of the low-IF which is determined by the sampling rate of the A:D/D:A). This approach means I can have multiple computers interacting with the K3. Maybe I want the main receiver data going to one computer, the second receiver data going to a second computer, the transmit data coming from a third computer, and a fourth computer controlling it all. Or I could have one computer controlling multiple K3's. It also means that the data on the wire is the standard which makes it easy for people to write software for different platforms, e.g. Windows, Mac, Linux, Java, etc. And it is time to start thinking of everything as data. Even audio is data since it is just bits inside the DSP. 73 de Brian, WB6RQN Brian Lloyd - brian HYPHEN wb6rqn AT lloyd DOT com ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Ultimatic keying in KX1/K1?
I hope I'm not reviving an old discussion here, but I searched the reflector archives and didn't find too much on the subject I have discovered that Ultimatic style keying is a lot easier for me and I send a lot better using it rather than iambic A/B. Is there any room in the KX1 or K1 roms for adding this mode in some future release? (Not asking about K2 'cause I don't own one... yet. K3 seems like more radio than I need, but awesome nevertheless.) Thanks, Mike N2HTT ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Elecraft CW Net Report for May 6th 7th, 2007
Good Evening, Well that was fun! 20 meters was much nicer than 40 this evening. 40 m had a great deal of static along with a flutter on some or a slowly rolling QSB on others. After Tom passed the net back to me the band had simply shut off so I was unable to attract another caller. But, between the two of us we collected a goodly number of you. I know I missed a few on 40 because of conditions but I tried to drag you through. There was one which Tom copied as a W1 and I copied a CJV. I am digging but am not able to construct the entire callsign. Hopefully next week you will check in again and one or both of us can copy you better.

Currently I am keeping the information in spreadsheet with six pages to keep track of names, states, call signs, serial numbers, and check in dates. It would be nice if I could start a new page of check ins while keeping the call signs down the left side with each column being the date. I need to figure out how to carry over the numbers from the first page of check ins while keeping the frequency histogram page linked up too. Hmmm ... I may need to give up sleep for a while to get all of my projects done! I am using Star Office so I won't raise my blood pressure while working with the Windows HELP system. Good thing Pat is not here :) She never did like my using Office tools while in the same house with her. Somehow or another she had the patience to work with them. Guess we are simply different in that regard! I am sure I'll come up with something to get the system a bit simpler. I am going to sit at the bench for a while this evening and continue soldering. I had forgotten how much fun and how soothing it can be to stuff boards and solder parts. I'll get through my pile of kits over the coming months so I can get to the ones I purchased at OzarkCon :) By the end of the year I may have saved enough to buy myself the KAT100 so I can switch antennas more readily. I may even dream of the new K3 but I'll wait for you others to find any problems with it before I jump into the fray. I learned my lesson long ago: I'll not be on the bleeding edge of technology unless someone else is footing the bill! Have a good week and I will see you again next Sunday, 73, Kevin.
