Re: [Elecraft] k3 with the w2ihy audio gear
Hi Scott - I have a "full W2IHY rack" (8-Band EQ, EQplus and iplus switch-box) that I use with my K3s and my non-Elecraft transceivers. I have used my K3s with everything from Yamaha CM-500 headsets to condenser mics to dynamic mics, with and without the rack, and I have received excellent audio reports in all configurations. I know everyone says that, but one member of my local club monitored me during Field Day (using a KX3 no less), and was "surprised" how good I sounded just using a CM-500 and the internal processing. The K3's signal chain contains a TX EQ, compressor and noise gate. Adjusted properly, you can obtain very good results with modest mics and no out-board signal processing. I consider, with respect to my W2IHY gear, out-board processing to be just "icing on the cake" and not a necessity with the K3.

Re: [Elecraft] Unhappy With Your KX3?
This is a great post Fred, and really goes to the heart of the entire "I bought a cat when I really wanted a dog, and now I can't the cat to act like a dog" issue that I have just been waiting for to appear here. I have had the good fortune to use WB8AZP's KX3 at a hamfest, and I think it performs great as a portable radio. It wouldn't make a great base radio FOR ME, but then I'm pretty sure that the KX3 wasn't designed for base use. Every device that I know of is the sum total of a set of design compromises. The design paradigm of the KX3 was clearly "portable operation", so it shouldn't be any surprise that the speaker is small and doesn't sound like an Apogee Scintilla. It's the same thing with boats - you "can fish from any boat", but don't get mad if the speedboat you bought isn't great for casting into lily pads for bass.

I too have looked and don't think Elecraft has ever *marketed* the KX3 as a home station radio, although it could certainly be used that way. So could an FT-817, K2 [I know of several in that sort of service], or even a K1. An ATS3x could be used that way too ... not its design goal however. If "it" receives and makes RF, you can use it at home. Everything I've heard from Elecraft, both in print [QST ads] and in person [Pacificon and elsewhere] have put the KX3 in the class of a "highly portable transceiver with a lot of K3-like performance and features." I've also never heard or seen it promoted as an "extreme backpacking trail radio" either, however it probably could be used as such under at least some trail conditions, although the KX1 comes to mind as a better choice at night in a tent. Every time I see a KX3, real or in a photo, it calls out to me, Business Traveler Radio, followed closely by Leisure Traveler Radio. I'm retired, I no longer do business travel, and my KX1, K2, K3/P3/KPA500/KAT500 are likely going to be it for me in the realm of Elecraft radios. But I've never seen the KX3 *marketed* as a home station radio, just that you can use it there as well as elsewhere. And to the discussion regarding loudspeaker quality: Folks, have you even bothered to look at the size of the KX3 speaker? Has everyone forgotten the physics of audio transducers? If you want incredibly full and great [near-broadcast quality] audio, I refer you to http://www.radioblvd.com/Pre-WWII%20Ham%20Gear.htm ... scroll down near the bottom of the page to "Hallicrafters SX-28 and R12 Bass Reflex Speaker." I inherited this receiver from the family of "Woody," W6ANX [SK], some years ago. The audio quality was incredibly good reminding me of the AM days when you could still hear the clang of the relays reverberating in his shack as your QSO buddy brought up his carrier. I used it in one Sweepstakes single band CW with an ARC-5 TX. Very nostalgic and fun ... for a couple of hours. :-) And, the SX-28 was great insurance against the possibility of gravity outages as well. I finally donated it to the museum so others could see and hear it and I highly recommend a visit if you find yourself in historic Virginia City NV. > > On 8/4/2012 6:42 AM, Oliver Dröse wrote: >> Nevertheless I would still expect from a rig marketed (not designed!) as a >> base station rig to provide sufficient audio from it's internal speaker.

Re: [Elecraft] K3 Mics
I'm not going to try to "sell" anyone on the idea of buying a "premium" audio chain, but... I agree the K3 provides "good" results with about any mic that can be attached to it. It has a good compressor, useful TX equalizer, bandwidth control and a noise gate. I have obtained "good" results with a Yamaha CM500 and, without processing, my Heil PR40 doesn't sound substantially different from the PR40 on the K3. But I do use audio processing on the K3 and my other transmitters, for several reasons. Probably the main reason is that I can make myself sound, within the previously noted 3 kHz bandwidth, sound "casually loud": optimized intelligibility without undue harshness. My station is, as are many people's, a collection of compromises controlled primarily by where I live. This is something I can "tweak", and thus I am gonna tweak it... Another factor is that I like to be able to switch TX audio properties quickly to suit operating conditions. I can switch very quickly between "casually loud" and "best-effort pile-up busting" very quickly, even as a DX station is responding to me so that I can go back to "normal" for the exchange. I adjust my transceivers "to" the rack, allowing me to switch between radios very quickly and still get the same "sound" from all of my transmitters. This is important as every phone transmitter I have every used has subtle (sometime not-so-subtle) differences in the way they sound on the air. Finally...I just want control over this set of parameters. I probably wouldn't make the investment if it were substantially more than what I spent, but as it is I'm very happy with the price/performance ratio. And that, at the end of the day, is what counts. I can't help but notice that this isn't the "cat's whisker and carbon mic" mailing list, so everyone here is making some kind of price-to-performance decision and I suggest that no-one's decisions in this hobby are un-assailable.

Re: [Elecraft] KXPA100 Shipping Status Update
- Forwarded Message - Another perspective is that this part of Elecraft's business is excellent (instead of "sucks") because we get advance visibility of products. At the same time we should realize the risk of advance notice is that factors out of Elecraft's control, e.g. parts availability, may slip the actual ship date. Ed W0YK/4 Excellent observations. The typical consumer electronic device product development cycle (not including market analysis and requirements development) is about three years, so Elecraft is completely within norms in this respect. You don't know, despite all of the modern analysis and modeling tools available, how something is going to perform until you build production-intent prototypes and start putting pressure on your supply chain. I think that this is another case where Elecraft's transparency has a down-side, and that down-side is that some of us have unrealistic expectations based on knowing when development started and the forecast start of production. I think that we need to remember that Elecraft is doing the best that they can to meet their forecasts and they give us a chance to participate in the specification of the product. This is, to me, greatly preferred to being forced to accept what a handful of detached, insulated engineers think that we need.

Re: [Elecraft] K3 using Pixel magnetic antenna
I use a Pixel Technologies RF PRO-1B magnetic loop with my K3 (and other receivers). How precisely you would connect it will depend on whether you have the second receiver installed, but the basic way is to connect to the RX Antenna port. You have a couple of options for feeding the second receiver, depending on how you connected the antenna input. The Pro is very effective below 15M, allowing me to "null out" much of the urban noise I cope with.

I just retrieved my SDR-IQ from the shelf, connected it to the IF loop on my P3, loaded SpectraVue set the External Radio/Panadapter Setup as recommended in the SV help file and was running with a "tracking panadapter" on six meters. I used the 2nd CAT port capability in microHAM USB Device Router to provide the serial splitter function and the K3 tracks clicks in the SV spectrum/waterfall and SV tracks frequency changes from VFO A on the K3.

WRONG! 30 dB down from 1.5kW is 1.5 watts. If that 1.5 watts is your neighbor a few miles away, he's 30 dB over S9 and the trash is on top of the S9 station you're trying to copy, you damn well WILL hear it, and you'll be thinking about putting pins in his coax if he doesn't clean it up.

I have a PixelSatRadio RF Pro 1A receive-only moebius loop antenna. It is being used with a Kenwood TS-440S that does not have the provisions for a receive antenna like the K3 does. In order to make sure one doesn't fry the antenna's pre-amp, I need a fool-proof way to ensure that no one ever accidentally sends RF down the coax to that antenna. I have thought about maybe some kind of a PTT enabled antenna switch. I have thought about some kind black box with a circuit one could build that would act as a gatekeeper to allow RF in from the antenna but block any going out. I have searched the 'net and have not yet found anything along those lines that I could implement. So my question to you is, can anyone here recommend such a switch or such a black box circuit? Or maybe propose something else that I'm not even thinking of? Any ideas, suggestions, recommendations?

Re: [Elecraft] D-Star
Don - I am not suggesting that you include D-Star in your products, and I am not going to change your mind, but I tend to disagree with the concern about D-Star over the proprietary nature of ABME... Not to split hairs, but the "mode" of D-Star is Gaussian minimum shift keying, a form of frequency shift keying. The D-Star implementation of GMSK is an "open" standard, and has been implemented at the hobbyist level. Which brings us to ABME, a proprietary "code-book" protocol (codec). I struggle with the lack of a published, unfettered standard as many do, but...I wonder how large of a practical impact this on me. I think about the other things that I can't make myself but leverage in my station, such as DSP controllers containing proprietary intellectual property and "microprocessor-based" transceivers (e.g. K3) from which I can not, to the best of knowledge, obtain and reuse the code. I think that one of the things that distinguishes "open" from proprietary is that I could, if I was so inclined, attempt to implement AMBE in software if ABME was "open". I am not so inclined, no more than I am inclined to "hack" my K3 or replace the DSP in one of my "other" radios with a custom FPGA. If the test for ABME is the ability of an individual or organization to implement it at-will and without royalty, then I would have to admit it fails...but...with all of the proprietary IP and non-reproducible components in my "amateur" systems, and knowing of the existence of a number of "modes" (protocols) that are implemented by one seriously-flawed PC application (that I can't decode by ear), I guess I just have a hard time seeing the big difference. In the end, I think D-Star is fun and probably less of threat to the long-term health of amateur radio than gentrification and apathy, but that's just my opinion... 73, Mike Alexander N8MSA amsct...@comcast.net - Original Message - From: "Don Wilhelm" To: "Greg Troxel" Cc: elecraft@mailman.qth.net Sent: Saturday, April 28, 2012 9:42:29 PM Subject: Re: [Elecraft] D-Star I agree fully, despite the article in the May issue of QST which glosses over the proprietary nature of D-Star.

The thought of paying for a license (even though that payment may be bundled with a transceiver purchase) is foreign to my views of ham radio. Certainly, I buy computers with Windows loaded, but I do not buy Icom transceivers with D-Star loaded. That is what is foreign to my view of ham radio.

Re: [Elecraft] Power Supplies
Most of the answer's to Fred's questions can be found on the company's website, but... - Yes, it's a switching design - The feet/tabs/protrusions are metal. These are provided so as to allow the user (installer?) to bolt them into a cabinet or onto a desk. There are adhesive rubber feet that are shipped with the supply. As for the entire switching/linear debate... I've used both over the years. I currently have an older (linear) Agilent supply in the shack which was the primary DC supply, as I am disinclined to use hobby supplies of any type. The Bulldog is, even when compared to professional gear, quieter, the output looks the same on a scope, I haven't heard it on my radio(s) yet and it emits much less waste heat than any linear supply I have ever come in contact with. The waste heat issue alone is one of my primary motivations for installing a switching supply, and is an important consideration in a number of commercial systems. High-quality switching supplies offering high "up-time" are common-place today in many mission-critical applications. Also, aside from the highest-quality, professional linear supplies, I have personally witnessed fewer transformer delaminations and filter capacitor problems from switching supplies. Yes, there are plenty of "bad" switching supplies out there, but then are "bad" linear supplies as well. I guess I just find it odd that several responses promote a brand of linear supply that has webpages devoted to address a myriad of shortcomings, and yet this supply is met with (in my opinion) excessive skepticism, primarily on the basis of it's "switching" design.

The days of Microsoft "ruining" USB on a monthly basis are long over, assuming they ever existed in the first place. And, while the cost of implementing RS-232 on a peripheral is very low, the cost of implementing high-reliability RS-232 on a current PC is actually increasing. Quality PCIe RS-232 cards, not the $35.00 paper-weights, are not cheap by any standards. I understand that the guy making band-switches in his garage won't want to pay $4,000 for a USB Consortium membership for a vendor ID, but at this level...I just don't get it...

It is very rare that one can find a modern PC desktop that comes with 1 or more RS-232 serial ports, just as it is becoming more and more difficult to find stock desktops with expansion slots on the MoBo. Laptops, at least newer than my ancient IBM Thinkpad, are even less likely to be equipped with RS-232 ports. This puts hams in an invidious position -- either use some old clunker of a desktop that came with RS-232 equipment, or find an expansion board that will plug into the MoBo of a moderately old tower, or use a USB-->RS-232 converter and go modern. Regarding the various items of Elecraft equipment, the choice between USB and RS-232 seems to have had very little to do with relative merits. It is not "which one is better?" but "which one is more suitable?" Apparently a substantial fraction of the brethren use superannuated desktops because this is a reasonable financial option. Another fraction of us use modern-day laptops, even though they promise half the performance at twice the price of a modern desktop. When the choice is between USB-->RS-232 conversion and RS-232-->USB conversion, the former is more readily available (the USB->RS-232 converters) than the latter. Again, this is just a marketing matter. Unfortunately, not all USB-->RS-232 converters are usable; some are "more equal than others" (apologies to George Orwell). A lot of the previous fuming and fussing over this topic has concerned specific chip sets and manufacturers of these converters. This is where the archived to-and-fro is of most utility. At first I was also a bit put off to discover that Elecraft relied on what I thought of as antiquated hardware, but in retrospect, I have gone over to the dark side and embraced the DB-9. I have used Firewire, USB, and RS-232, and find I much prefer the latter. I am fortunate to have a desktop with expansion slots, though in a bit of a quandary planning for the succession.

Re: [Elecraft] XG-3 - why RS-232
This is another common misconception. All of the microprocessor vendors that I am aware of have built-in USB peripherals, and often have reference drivers and driver templates. Assuming that Elecraft uses MicroChip PICs, there are few reasons to add an off-package USB peripheral. MicroChip has an excellent USB section at their website that covers USB (as it relates to their microprocessors): http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1486 Mike Alexander - N8MSA amsct...@comcast.net - Original Message - From: "Kevin" To: elecraft@mailman.qth.net Sent: Saturday, May 12, 2012 9:09:45 AM Subject: Re: [Elecraft] XG-3 - why RS-232 Probably because that would put Elecraft squarely between you and the guy at Prolific or FTDI who writes the drivers.

Re: [Elecraft] XG-3 - why RS-232
Topic by topic: >Many microprocessor controllers have...built-in serial ports Correct, and usually I2C, EtherNet, SPI and a host (pun intended) of communications peripherals. But even the beefy Motorola/FreeScale SCI (similar to a UART) ports need, in almost any implementation that I am familiar with, buffer circuitry - I hope no-one is routing the uC directly to a connector. USB needs a similar buffer circuit, known as a transceiver, which provides signal-level conversion and isolation. That's it...there is no UART in the classic sense. And RS-232 serial ports are rapidly become scarce on microcontollers...just go their websites and read the datasheets. >The low power line drivers consume less power, need fewer parts (no crystal), >can be smaller than the USB UART and are likely to be >more reliable. Again, no-one really needs free-standing USB protocol units (chips) anymore, so the "crystal" comment is irrelevant. Aside from peripheral power supply capability, which is optional, the signal driver power demans are actually similar, the USB using a low-voltage differential-mode signal with moderate drive currents, and RS-232 are high-voltage (5-25V), single-ended signals with low drive currents. As for reliability...there are a thousand factors to be considered, and I don't see any data anywhere to back that up. >If you want USB... That's where we run into problems. "Adapters" are inherently less stable than well-implemented on-device peripherals. That's why people such as myself want native USB capability - conversion is not the same, despite assertions I have seen in this mail list and in other forums. I realize there will be a cost delta between RS-232 and USB, and there may not be a business case on a hobby product. I can live with that on some devices, such as the XG-3, but I am really beginning to struggle with RS-232 on transceivers and similar devices. It just doesn't make a lot of sense to me anymore, and that's coming from a person that has done embedded system design using both RS-232 and USB. I'm not knocking Elecraft, but I think that, based on today's PC market and the maturity of the alternatives, the era of RS-232 as the only choice should be drawing to a close.

Not so ... many microprocessor controllers contain one or two built-in serial ports. It is far cheaper to adapt those TTL (or 3.3V) ports to RS-232 "compatible" operation (typically a single line driver) than to install a USB UART and deal with drivers for a multitude of operating systems. The low power line drivers consume less power, need fewer parts (no crystal), can be smaller than the USB UART and are likely to be more reliable. If you *want* USB interface to the XG-3 pick up one of the USB "scanner programming cables" - typically USB to RS_232 compatible 3.5mm stereo plug. I believe Elecraft have such a cable as the KXUSB (standard for the KX3) ... I don't know if they list it separately as a spare. 73, ...

Re: [Elecraft] OT: Dayton New Equipment Show
Direct digital conversion radio receivers rarely connect the A/D "directly" to
the antenna input, the term "direct" referring to a lack of analog frequency
conversion (mixing). The Flex 6000 series is no exception to this trend. There
is a gain and filter stage ahead of the A/D, and presumably an AGC.
This is how dynamic range is managed on this, and many similar receivers.
Blocking is a concern, but not even the greatest concern. Analog signal levels
should, regardless of the number of discrete measurement steps ("bits"), should
be kept well above the minimum input level to avoid excessive quantization
error levels.

Subject: Re: [Elecraft] OT: Dayton New Equipment Show
The Flex 6000/6700 is an "on frequency" direct digital conversion
radio - that is a 16 bit analog to digital converter operating at
the "front end" of the radio with no intermediate conversion/IF
and filtering stages. In addition, all of the DSP is contained
in the radio (no more PowerSRD). The new software for the Flex
6000/6700 (reportedly "PowerRX") is essentially a "glass control
panel").
A general purpose computer is required for PowerRX but communication
between the computer and transceiver is via TCP/IP which means the
computer can be anywhere. Audio input and output will be available
both on the transceiver and from PowerRX (interesting for remote
operation scenarios).
The issue will be the severely limited dynamic range of the 16 bit
ADC. Without effective AGC ahead of the ADC there *will* be overload
problems on crowded bands (e.g. 160/80/40) where any transceiver must
deal with many extremely strong ("local") signals while maintaining
maximum sensitivity. With AGC, the strong local signals will cause
"blocking" as the gain is reduced to prevent overflow of the ADC.
The new Flex design is certainly "interesting" but may not truly be
ready for critical "real world" use with the widely varying signal
levels in amateur service.

Re: [Elecraft] SDRs and embedded processors
"Redesigning" an existing device to use a new microcontroller (not a PC microprocessor) is non-trivial; even pin-compatible parts often have changes in memory layout and peripheral addressing that drive software updates, compiler updates, etc. And if a pin-compatible part isn't available, then...it's a huge effort. I lived through this when last year's Tohoku (Japan) earthquake and tsunami caused a key Renesas plant to close, causing a huge scramble by automotive OEMs to change microcontrollers. There was a lot of pain and expense involved... And I strenuously disagree with the assertion that USB 2.0 will "go the same way as FireWire". With an installed base estimated to be 15 billion devices, and full backwards compatibility from the successor to USB 2.0 (USB 3.0), I see a very long life for USB 2.0. More microprocessor and microcontroller architectures are including embedded USB 2.0 peripherals every day, and the roadmaps that I have seen show this trend continuing for the foreseeable future. RS-232-style ports are, on the other hand, not included in many new micros and are rapidly disappearing from silicon vendor roadmaps.

Re: [Elecraft] K3 RTTY contest
I used mine in this weekend's ARRL Round-Up in conjunction with N1MM (using the FLDIGI modem) and a sound card. The system, of which the K3 is more or less the RF "front end", worked great. It's nice to be able to pick out an S3 multiplier station next (next-next) to an S9 +30 "honker" with no AGC pumping, de-sense, etc.. I owned a Flex 5K until recently (still pictured on my QRZ page, have to update that) and I have to say the K3-based combination works better in terms of RF performance and interoperability with contesting gear. I'm no K3LR, so take my experience with a grain of salt...but it works for me. 73, Mike Alexander - N8MSA amsct...@comcast.net - Original Message - From: "barry whittemore" To: elecraft@mailman.qth.net Sent: Wednesday, January 9, 2013 12:45:22 PM Subject: Re: [Elecraft] K3 RTTY contest Bill, I use RTTY often in contests and find it incredibly easy to use. I built a very simple interface and use FSK rather than AFSK. that does not require any adjustments etc. I do some of the AFSK modes as well but one mans settings will not be the same as another depending on software volume levels etc. it is just a trial and adjust but it works well and is an easy process. I can send you a pdf of my interface cable if you like. It works good but requires its own serial port. I have used it with a "real" serial port as well as a USB to serial adapter and it works either way. with the FSK there are no level adjustments needed. I have not used an FT5K but i used to have an FT1000 MP that i loved but i find my K3 to be the absolute best radio i have ever owned. its almost effortless to go from one mode to another. no relation to Elecraft other than a very happy owner.

I know the K3 is a great radio but I don't seem to read too many operator comments on its greatness.. thanks all.

Re: [Elecraft] why mix rf connector types within the product line?
Engineering perspective? I'm an MSEE, have been working with BNC connectors for thirty years and I don't have issue with their use on HF radio gear. If they're good enough for Agilent, Rohde and Schwarz, Anritsu, et al, they're good enough for a 10W HF transceiver.
