[Elecraft] K3 and SDR Integration - Almost completed!!!
Scott,
Did your TS940 require any kind of a special buffer
circuit to keep the softrock lite from injecting noise
into the IF, as the K3 might require?

[Elecraft] Collins cost
I bought 17 Vietnam-era Collins KWM-2As here in Bangkok 5 yrs ago. Also 7 remote VFOs and assorted ps and bolt on ps and Station Control units. Many were damaged in various ways, but the point is that all but one could have been restored to working order. The one was obviously used for parts as many were missing. I sold all but 2, giving one to the finder/cleaner here and have the other mostly restored. Included was one with Rockwell Collins label. I sold all these one at a time to hams in usa and JA. I know they went to good homes. Here in HS, I have 2 KWM-2As restored with remote VFO units. HS1CKC and I love Collins and he likes to say "Collins never dies." Who knows what it would cost to make and sell one new today?

Re: [Elecraft] that Drake or Collins "sound"
I still use the TR-4 for SSB and also have the R4B. Using the same antenna the Drakes pull in the same weak signals as my K2 except the K2 eliminates the QRN/QRM quite a bit better. As far as sound quality, using the Drake MS-4 cabinet with the original Drake speaker and comparing it to the K2 standard in-cabinet speaker, the Drakes are a joy to listen to. I'm sure that with a better speaker system the K2 would improve. I may sell the K2 someday if I were to get the K3 but the Drake gear is priceless! 73, Jim/k2hn Shape Yahoo! in your own image.

[Elecraft] K3: 21st century assembly "manual"
Hi all: Well, I would like to see streaming video for the assembly instructions. As (if) things change, simply add a modify the link for that portion of the instructions. And no real language issues! Photos are nice, but hey, kinda fossil-technology. de Doug KR2Q http://photo.net/history/timeline and from http://www.rleggat.com/photohistory/ The first successful picture was produced in June/July 1827 by Niépce, using material that hardened on exposure to light. This picture required an exposure of eight hours. On 4 January 1829 Niépce agreed to go into partnership with Louis Daguerre . Niépce died only four years later, but Daguerre continued to experiment. Soon he had discovered a way of developing photographic plates, a process which greatly reduced the exposure time from eight hours down to half an hour. He also discovered that an image could be made permanent by immersing it in salt. Following a report on this invention by Paul Delaroche , a leading scholar of the day, the French government bought the rights to it in July 1839. Details of the process were made public on 19 August 1839, and Daguerre named it the Daguerreotype. The announcement that the Daguerreotype "requires no knowledge of drawing" and that "anyone may succeed and perform as well as the author of the invention" was greeted with enormous interest, and "Daguerreomania" became a craze overnight. An interesting account of these days is given by a writer called Gaudin , who was present the day that the announcement was made. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] that Drake or Collins cost
My parents bought me a Swan 400 when I passed my general at age 14 in January 1964. I went from WN2MIC to WB2MIC and CW at 13 wpm was a piece of cake. That rig with no bells and whistles was $1,000 new. Inflate that over 44 years! Rigs today are a bargain, and feature packed, by comparison. I must say, however, that I thoroughly enjoyed the 320 watts DC on CW and 400 PEP on SSB. It was new teen ham's delight to operate. BTW, my novice station was a Hallicrafters HT40 (I still have one) and a Lafayette HE30 receiver. I now use the HT40 along with a Collins R390A for kicks every once in a while. And then I run the K1 or IC-756 PRO III. All great fun.

Because they were making a ham rig, not a commercial one. What the commercial services do isn't always the best thing for amateur radio applications. There's nothing theoretically wrong with audio injection for CW. But when a rig that cost as much as the KWM-2 did in its time expects the op to listen to 2 kHz tone on CW, doesn't provide a narrow filter even as an option, nor RIT or AGC OFF, I call shenanigans. The KWM-2 was meant for *amateur radio* SSB, and it had no peer in that role in its day.

Re: [Elecraft] K3 and SDR Integration - Almost completed!!!
I personally think that going the SDR route is overkill - and requires a ton
of code.
Simon! I can't believe what I am hearing from you! :)
In about a months time, I went into the PowerSDR code (v1.9.1) and
interfaced it to your Ham Radio Deluxe using DDE. I have the PowerSDR
software sync'd perfectly to HRD - you can tune either the PowerSDR or
the rig (and change modes). I have been using it with my Kenwood
TS-940S with a Softrock lite kit for the last two months.
RIght now I am fixing up new ("IF Stage") setup menus so that one
can input custom data about their setup by mode (since most rigs shift
frequency when modes change) - so that any radio can be used. For
example, the IF center frequency and any desired offset between the
PowerSDR and radio VFO's is something one must specify. You can also
specify the frequency range of the radio (i.e. 1 - 30Mhz).
Just need Elecraft K3 support from HRD and we are all set!
As for me I have been working on every free moment I can find to get
this code completed and out on the web. I will be sure to post here
when I get the code packaged and up on my
website. I will have a K3 from the third batch in my hands when it
comes out - so yes I will be testing that radio personally.

Re: [Elecraft] that Drake or Collins cost
Stephen W. Kercel wrote: Charles and all: In 1964 the basic Drake 2B receiver without the Q-multiplier was $279. Using the Bureau of Labor Statistics inflation calculator, that is the equivalent of $1875 in 2007. I used a KWM-2A on CW as HS1FJ for about 6 weeks in the mid-60's. I was CW only, and don't recall any problems [other than having the entire planet call me :-) ]. It was VOX QSK of course. I had an S3-line for many years, again mainly CW, and don't recall any issues. In both cases, CW was with headfones, and the SSB quality depended heavily on the speaker I was using. I had a 2B also, and until I got my K2, really thought it was the greatest rx I had ever seen, better than the 75S3, but again, "sound" quality depended nearly totally on the speaker. The filters in my K2 rival the Collins mech filters, and in fact have gotten me back into RTTY contesting. FWIW: In the 3.8 years I served in the USAF in SE Asia in the 60's, we had KWM-2A's in every environment you can imagine. They got beat up in trucks and jeeps, full of sand and dirt, wet, overheated, and subject to less than ideal power regulation [OK, really crappy regulation]. They tolerated extreme VSWR. We pulled them out the back of low-flying C-130's on shock pallets with snap-opening cargo parachutes [LAPES] in the middle of the night, they fell off tables and boxes being used as tables when someone tripped over the coax or power cord. They became scratched and worn. I remember one that fell on the front panel and fractured the tuning knob. Our depot in the Philippines sent a new knob and the radio continued to work just fine. In all of this, the failure rate was exactly zero ... a very good thing since more than once, our survival depended on the KWM-2A working. I wonder how many $10K radios of today could duplicate that reliability and durability? Rest in peace, Art ... and ignore all the latter-day critics. Your radios were engineering marvels. I now have another engineering marvel on my desk, it's much smaller and lighter than a KWM-2A, and its performance surpasses your marvel. Fittingly, its name begins with a "K". A number of our airborne missions required that we destroy all of our gear with thermite when we ran out of JP4 for the turbine generators and the Army came to recover us in a couple of CH3's. We had two KWM-2A's on every mission. We ran 21 of those missions. Does anyone know how hard it was for a ham to purposely destroy 42 KWM-2A's? :-( I'll be in the Flight of the Bumblebees this coming Sunday with my K2 and KX1 as back-up. Hope to work a bunch of Elecrafters. 73, Fred K6DGW - Northern California Contest Club - CU in the 2007 CQP Oct 6-7 - www.cqp.org K2 #4398 KX1 #897 KPA100 KAT100 ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 and SDR Integration
HB9DRV: >I personally think that going the SDR route is overkill - and requires a ton of code.

Re: [Elecraft] K3 and SDR Integration
- Original Message - From: "Bill Tippett" <[EMAIL PROTECTED]> W0YK's comment about missing the Pro3 bandscope reminded me of this. I hope someone (K8ZOA, HB9DRV, N4PY or ?) will look into integrating SDR software (Rocky, PowerSDR, etc) with the K3 and Softrock hardware on the K3's 8.215 MHz IF output. What I would love to see is: 1. A bandscope display (good sensitivity and resolution). 2. The ability to place a cursor on a signal of interest. 3. Clicking the cursor moves the K3 VFO to that frequency. 4. Perhaps add a waterfall display for weak signal work. I personally think that going the SDR route is overkill - and requires a ton of code. But - having had a bandscope on my IC-7800 (now sold) I would dearly like a bandscope. I do hope that Wayne and Eric and their friends will investigate and design this once the dust settles later this year. I honestly don't want to get inside the SDR code - I just don't have the time. At one stage I was planning to do this but I'm having to spend significant time on my commercial activities. An Elecraft or Elecraft-approved bandscope with a serial or USB interface would be my preference so that I can integrate it with my software.

RE: [Elecraft] that Drake or Collins "sound"
Yes, good point Don. When I did my tests, I fed the antenna to both rigs and tuned them to the same signal. I routed the rigs headphone output to a mixer and then to the Delta 44 sound card in my computer. The signals were recorded in Cakewalk Home Studio. This allowed me to listen to how each rig did on the same signal at the same time and to listen to it under studio headphones. The rig's speaker was not part of the equation. - Keith N1AS - - K2 5411.100.ssb - -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Don Wilhelm Sent: Tuesday, July 24, 2007 11:49 AM Cc: [EMAIL PROTECTED] List Subject: Re: [Elecraft] that Drake or Collins "sound" I am not certain what speakers you folks are using for these comparison tests, but if using the internal speakers, that alone can make a big difference.

The keyer was homebrew and a NC contact on the keying relay activated the R4B muting circuit. After the addition of one bypass capacitor in the audio of the R4B, I had what I remember to be absolutely perfect QSK. When I turned off the sidetone from the keyer, keying the transmitter (about 250w input) resulted in smooth pulses of silence from the receiver. Maybe it's like your first girlfriend, the way time clouds memory, but this is the standard that I apply to modern rigs, most of which don't come close.

I had hoped I'd have it at the beginning of Aug, not so I could assemble it - too much going on in Aug for that. But so I could read the manual during my 2 week vacation at the end of Aug. Is there any chance of an early release of the manual in electronic form? The problem is that the documentation, including the Owner's Manual and the kit Assembly Manual, will be finished *after* the last changes to the K3 are made and tested! Wayne is spearheading the Owner's manual because the ongoing work on the firmware has a huge effect on the operating instructions. Obviously, those instructions will continue to change as long as tweaks are being made to the firmware! I'm pursuing the kit assembly manual. Under Wayne's direction, our goal is to 'raise the bar significantly' in making the K3 an even easier kit to assemble and to assure builders that your kit-built K3 meets all the performance specifications of the "factory assembled" K3s. Although no soldering is involved, there are a lot of things to do to put a K3 together and the manual leans very heavily on photographs and drawings illustrating almost every step! As minor changes to the hardware are made the illustrations need to be changed and new pictures shot in order for the parts you find in the kit to match the photographs and instructions. So, once again, changes are on-going as long as the testing and tweaking of the K3 goes on. I've had a K3 in my lab for over a month, all in parts. It arrived ready to operate, but my first order of business was to take it to bits in order to work out and validate the assembly procedures. No one is more interested than I in seeing it all in one piece again, making RF and hearing signals. I suspect that will happen only after the first K3s are in the hands of those of you who are patiently waiting.

-Original Message- From: Brett gazdzinski <[EMAIL PROTECTED]> On the kwm2 and kwm2a, cw was an afterthought, and done in a poor way. I think they used audio tones into the mike circuit for CW, and maybe the ssb filter? The KWM-2 and -2A did indeed use audio tones for CW. They used a very high tone (to most CW ops) so that the unwanted-sideband rejection would be good after the filtering. I don't think those rigs were great CW radios. They were barely usable on CW IMHO. No RIT, no sharp filter, no way to turn the AGC off nor to change its characteristics without a soldering iron. It didn't have to be that way. A carrier crystal setup could have been used instead of audio injection. Collins made narrow mechanical filters that could have been used, etc. They were primarily SSB rigs, pure and simple. And they did that job very well, particularly compared to what else was available to hams at the time. Perhaps Collins was concerned that if they made the KWM-2 a really good CW rig, it would hurt sales of the rest of the S-line. Unfortunately, most of the HF ham transceivers for the next decade or so imitated the KWM-2 in many ways. I don't suppose any of the old stuff would be any good in any contest, but maybe some of it sounded much better on all modes. Depends on which rig and how it is used. I have used older rigs and homebrew rigs using very old technology in contests with very good results. The rig you see on my homepage was responsible for over 620 QSOs on FD 1995 with only simple antennas. Not everyone contests or goes after rare DX, but everyone seems to be stuck with poor sounding radios these days, I'm not. Two reasons: Elecraft and homebrew. because they are built for contests, or for general coverage from 50KHz to 50MHz, or use noisy parts, or poor designs, or whatever A lot depends on what someone considers "good sounding" and "poor sounding". In my experience there are all sorts of factors: - Harmonic distortion (audio) - IM distortion (audio & rf/if) - Phase distortion (mostly IF) - AGC characteristics (or lack thereof) - Smooth vs. sharp rolloff of filter characteristics, filter ringing, etc. What some ops describe as "noise" is often actually distortion in some cases, AGC artifacts in others, and filter response in still other cases. Or a combination. 73 de Jim, N2EY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list. Subscriber Info (Addr.

[Elecraft] K2 Rocking in Bermuda
Greetings from Bermuda! The K2 is putting on a stellar performance here on the North Shore. I arrived late Sunday and have logged over 250 contacts in a little over 5 hours of operating time. It could have been more, but sightseeing with the family was a *big* part of the negotiation. My goal is 2000 contacts by our departure date (Sunday). Should be attainable. The antenna is a G5RV and the KAT100 is loading it to 1:1 on most of the bands. Listen for me after 8pm around 7010 and 10110. And 14010 during the day (when I can squeeze in a moment). Man, working a pileup is great fun! I think I'm addicted. 73, David VP9/W4SMT ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] K3 and N1MM
I've not seen any comments regarding the k3/N1MM combo. Any problems here?

RE: [Elecraft] that Drake or Collins "sound"
I did some A/B testing with my K2, Drake 2B and R4A. The 2B was in fabulous condition and had the Q multiplier. The 4A had some issues which made it work just not quite right. I found the 2B to be a wonderful sounding rig for CW. It was warm and rich and the signals had a smoothness that was wonderful. The K2 didn't sound a nice but it wasn't that far behind. The AGC in the Drake was not my cup of tea. It attempted to keep everything at the same output level (no slope) so the background noise between elements was as strong as the signal. Also, it was slow on the attack. The leading edge of most elements had a spike for one audio cycle that could be seen in Spectrograph (or whatever it is called) but was quick enough to not be heard. That spike would cause the AGC to over react a bit so the first part of a long dash would be a bit quieter than the latter part. Still, the sound was very sweet. The K2's AGC was more up to the task. There was no slow reaction, no overshoot on the leading edge of an element and no over reacting. In the end, the sweet, smooth tone of the 2B was not enough to trump the better overall performance of the K2 who's received tone very good. We talk about Drake, Collins & the great rigs from years ago, but I'd like to suggest that thanks to Elecraft, THESE are the good old days! - Keith N1AS - - K2 5411.ssb.100 - ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] that Drake or Collins "sound"
Perhaps the one thing that we are all overlooking in the nice sound of the Collins and Drake radios is that their bandpass was much wider than the modern day radios and today there is far more QRM on the bands due to increased numbers of amateurs in the same spectrum. I loved my KWM-2 and used it for 14 years but doubt that it would be a very good radio to use in a contest in this day and time.

Re: [Elecraft] KX1 typical power out (or, manual anomaly?)
John, If everything in the low pass filter is correct, you will normally have greater power out on 40 than on 20. So do check all the capacitors in the LPF area, be certain K2 is operating when on 40 (c48 and C49 are switched to make contact with ground on the bottom end). Then after all that is checked, be certain you have the correct number of turns on L1 and L2. Is is possible that you spread the turns on L2 too far - it may be worth compressing them a bit to fine out. 73, Don W3FPR John Shadle wrote: After performing my repair last night, I read through parts of the manual again and noticed this on p. 59 of the manual (my Rev. B as well as the current version Rev. C) "With L2 at its optimal turns spacing (for best harmonic rejection), 20 meter output will be about 0.3 to 0.6 watts lower than 40 meters." The odd thing is that I am getting 1w less on 40m, *not* less power on 20m. Is this typical (more power out on 20m than 40m) or could there be a problem somewhere in my assembly? I know that 4w on 20m and 3w on 40m is typical (and I'm fine with that), but wouldn't you expect higher power on 40m according to this statement in the manual? -john W4PAH ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

[Elecraft] Re: Shipping Status
Well, I had half expected it and was hoping it wouldn't be late (as I'm sure lots were) and I agree with the others, do it right. I had hoped I'd have it at the beginning of Aug, not so I could assemble it - too much going on in Aug for that. But so I could read the manual during my 2 week vacation at the end of Aug. Is there any chance of an early release of the manual in electronic form? -- If all our misfortunes were laid in one common heap whence everyone must take an equal portion, most people would be contented to take their own and depart. -Socrates (469?-399 B.C.) ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
