Re: [Elecraft] WWV Clocks -- It's really WWVB
Twice a year, I take my clocks out to the back porch and out of my shack/office. That is around the time of DST/ST switches. The rest of the year, my "Atomic Clock" from LaCrosse is always in perfect sync to the ability of my eye to detect. I always do it after the switch because I never remember to do it before the switch!. In central NJ, FN20rg, in eight years of owning this clock, I have never once had this procedure fail: back porch with full western exposure, one night, the clock resets and from then until the next change over, it keeps great time. After acquisition, it seems to do some kind of matched filtering for "what it expects" to stay synchronized and gets better Eb/N0 performance as a result. I have repeated this every time I need to replace a battery or change ST/DST. Bob N4HY John Magliacane wrote: Hi Craig. We have a total of 8 "automatic" WWV synched clocks of various types... And I live 30 miles from the WWV transmitter. Incidentially, it is _WWVB_ on 60 kHz, not WWV or WWVH on HF that is used by these "radio controlled clocks" for periodic time checks, usually once a day during the early morning hours (local time). Despite your short distance to WWVB, you still might be experiencing poor reception due to local interference sources. Computer monitors, switching power supplies, AC operated motors, and thunderstorms tend to generate a lot of 60 kHz noise. I'm 1622 miles east of WWVB and own a WWVB-based frequency standard / UTC clock of my own design. Even at this distance, when proper receiving techniques are used, reception of WWVB is generally excellent, day or night. 73, de John, KD2BD -- AMSAT VP Engineering.

[Elecraft] Off topic
This is off topic but Frank and Wayne and Eric know each other and Frank is an Elecraft owner and enthusiast: On December 22 at Carnegie Hall, the New Jersey Composer's Guild will present "Answer to Job, An Alternative Holiday Concert".Frank Brickle (AB2KT) is the secretary of the Composer's Guild of New Jersey. He has composed an opera which will be performed during this concert: http://www.williamanderson.us/index_body.html Frank's opera is a Townley Mystery Play. Mystery plays or miracle plays are medieval religious dramas based on stories from the Bible. Mystery plays were performed around the time of church festivals, reaching their height in Europe during the 15th and 16th Centuries. A whole cycle running from the Creation to the Last Judgment was performed in separate scenes on mobile wagons by various town guilds. Four English cycles survive: Coventry, Wakefield (or Townley), Chester and York. They were intended for the common person. In many cases, it was the only way people could hear the stories of the Bible in their common tongue, rather than in Latin. Frank's composition, "The Creation of the World" will be performed during this concert. The tickets are not yet on sale, but you may visit the Carnegie site and soon enough the "Buy Tickets" button will open. http://www.carnegiehall.org/article/box_office/events/evt_7356.html?selecteddate=1005 Frank is a member of the American Radio Relay League SDR Working Group, a GnuRadio enthusiast, contributor to the ARRL/HSMM/SDRWG OFDM modem project, AMSAT member and a member of the Eagle/Phase 3 Express Software Defined Transponder and CC Rider Team for Eagle, coauthor of the DttSP Software Defined Radio package (the SDR core for the Flex Radio SDR-1000), and recently retired from IDA's Center for Communications Research in Princeton, NJ. He did not stop working on technical problems to return exclusively to music as he is a regular consultant to Isigtech, Inc., has recently consulted for CNS Systems, Inc., and has consulted for many large firms including Agilent. The work he did for IDA CCR earned him a very prestigious award from the U.S. government (the Anne Z. Caracristi award) in 2000. He has consulted with many other firms in matters related to signal processing problems which need statistical detection or classification algorithms. Frank has demonstrated a flair and genius for this type of signal processing problem.Frank is the author of an interesting article in QEX Nov/Dec. 2003, "Automatic Signal Classification for Software Defined Radios". This was the first article published in the growing area of cognitively defined radio with a view to amateur radio applications but not limited to amateur radio. A Princeton University alumnus, he studied under one of the most influential American composer's: Milton Babbitt. Under Babbitt's tutelage, he earned his Ph. D in musical composition.Frank was recently an organizer of a festival of music celebrating the life and work of the composer George Antheil: http://www.paristransatlantic.com/festival/index.html As an interesting aside, Antheil and actress Hedy Lamarr are credited with creating frequency hopping spread spectrum for use in torpedo guidance systems during world war II and were granted a patent. One could easily understand why Frank would find a kindred spirit in Antheil. To listen to some of Frank's compositions, one need only use Google. I suggest you search for "Brickle Merlin". You will find an mp3 of one of his compositions that will stream. The best word I can think of to describe Frank without listing more achievements or writing an unauthorized biography is polymath. http://en.wikipedia.org/wiki/Polymath It seems appropriate as you can see from this list of recent achievements,interests, and his educational achievements. The word is inadequate, but is a useful beginning place to explore this talented and complex man. It is the best my limited command of language will allow me here. Please join me in celebrating my best friend's achievement and I hope you will enjoy the NJ Composer's Guild offering in Carnegie Hall in December. Bravo Frank! Cheers!

Re: [Elecraft] K2 has ONLY 80dB of third order dynamic range vs SDR-1000 98dB
Mark: As you know I am a big supporter of the SDR-1000, having written much of the code that makes it run. I also own K2 serial number 4201 which I built and proudly operate all the time. For years, there was not a receiver that could compare to the Elecraft K2. It was and in many ways still is the "standard to beat". The debt of gratitude we owe Wayne and Eric for doing this project and the many others they have done and are doing, is beyond compare. Elecraft is DIRECTLY responsible in my opinion for the levels to which receivers have risen. Until the SDR-1000 with its new front end, you had to pay thousands to get a comparable receiver. Every single day that I worked on the SDR-1000 front end refinements, cajoling, begging, and FINALLY doing it myself, was directly attributable to the fact that I could not stand the front end overload on the SDR-1000 and saw what Elecraft had achieved. Time and technology marches on. The Sirenza parts we now use in the SDR-1000 did not exist when Eric and Wayne did the engineering. That said, the Elecraft K2 still kicks EVERYONE's behind in the total composite noise department because of their foresight in making this both a DDS based VFO AND following that DDS based VFO with a PLL to clean up the spurs. In the article you point to, which will be in the upcoming QST, http://www.flex-radio.com/articles_files/2005-10_QST_Review.pdf, you can the DDS spurs in the "worst case" composite noise picture. You can see that at 60 wpm, the dits are two entire elements behind the key closure. I could go on, but the facts are, there is much more to comparing transceivers and receivers, than just the receiver dynamics numbers. Yes the SDR-1000 has the best close in dynamic range right now. That will fall soon. The need to pack more transmitters into more and more crowded spectrum is driving the manufacturer of higher dynamic range and higher "IP2,IP3" and BDR receivers. I am EXTREMELY proud of the work I have done on the SDR-1000 with AB2KT and the folks at Flex. Frank and I are proud owners and regular users of our Elecraft equipment, and we will continue to be. 73's Bob N4HY Mark Tyler wrote: http://www3.qth.com/pipermail/flexradio_flex-radio.biz/2005-September/00 2299.html ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

Re: [Elecraft] K2 Internal Speaker Now Alive and Well
I looked for a while for a wiring error in 4201 before I found I did exactly the same thing. I also looked for low power for days and then Gary pointed out that the bias resistor on the bottom of the board (the one I marked as having been installed) was not installed. This is a complex kit with many parts and "stuff happens". Elecraft's secret weapons are their novel use of this exploder, having Scott and Gary fix us up with lost parts or building difficulties, and the fantastic repeatability of the design. I agree with the tunnel vision part. I definitely developed it on the bias resistor probably because it is somewhat painful to remove the bottom and look, (hindsight being 20-20 and all). I did this several times during the course of events. I found building this to be a good learning experience and while more difficult than my SB-110, DX40, and DX60, it was also more rewarding.

RE: [Elecraft] RF Noise canceller ?
-Original Message- Would this type of noise canceler not work on "white" noise also ? ___ The simplest answer is no. White noise typically arrives from random directions, with random phases, random polarizations, etc. etc. etc. and are usually from thermal and uncorrelated sources. The principle of operation of these phasing units IS THAT THEY CAN BE PHASED to eliminate unwanted signals since they are from a sufficiently point like source that a null can be tuned on top of them. How is this done? You can arrange to add an interfering signal 180 degrees out of phase with one from the intended antenna while not killing the signal of interest to the point it is not heard. In other words, you increase the signal to (signal+interference) ratio. To the extent that this is automated, it is a "smart antenna". The importance of them having equal responses to the interferer so that simple phasing works is a tricky business. If amplification is required to do this, then you have the myriad problems (IP3, IMD, DR, MDS, etc) to deal with in this new system. Since we are not asking for a perfect null, but some serious suppression, these conditions can be relaxed. If the noise source is localized or coming from a direction that is not nearly collinear (within the 3dB beamwidth of say a directive antenna) with the signal of interest, it can be nulled with these phasing methods irrespective of its power spectral distribution, white, poisson, tone, etc. This is all reasonably complicated as you can see.

For what it might be worth to anyone else. 73, Tom N0SS For the Hakko 808 Desoldering gun, consider also ordering a couple additional nozzles: A1394 This is a long (0.434"), slender (0.090") nozzle which will allow you to get into places the fatter tips won't. It is particularly handy when you are working on PC boards which are pretty tightly packed AND which have some of their components mounted on the bottom of the PC board with the soldered pads in and among the tightly packed components on the top side. Because it is long and slender, this is a 'delicate' nozzle, and probably NOT one you would want to leave on the desoldering tool when you do not need to use it. A1396 This is a short/fat nozzle, similar to the nozzle provided with the Hakko 808 when it is originally purchased. However, this nozzle has a 0.091" inside diameter, so it will suffice for removing most, if not all, of the connectors used on most PC boards. Some of these connectors use flat lug-type leads, instead of wire leads, which can be particularly difficult to remove if you find you must remove the connector itself. Of course, it also works well on the larger diameter leads of big diodes, etc. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

You mean tips for the 936? The 808 I have is a one size fits all and it is strictly for plate through holes unless great care is taken. For SMD I would use solder wick and/or a cutting tool! Those are both great tools. At the same time get some tiny solder. I use 0.015 and 0.020 for kit building. With 0.015 it is pretty hard to flow too much solder unless you are really trying.

RE: [Elecraft] K-2 vs SDR-1000
In results obtained by me with Leif Asbrink on 14 Mhz, the IP3 is over 10dBm you set the thing as it should be. The Elecraft K2 is 20+ dBm with preamp off at 5 Khz. SDR-1000 BDR is 105 dB, the Elecraft K2 is 135 dB It IMDDR3 is 99 dB, the Elecraft K2 is better. The DDS does produce spurs BUT the DDS is not directly driving the mixer. This is often misunderstood. The DDS output does not even touch the mixer. The DDS output is hard limited and that hard limited signal is using to drive a switched capacitor network. What spurs there are, are CONSIDERABLY better than driving it directly. In this regard Eric is slightly off in his implications in that if driven directly by the DDS, the mixer would be a mess. The worst spurs are "buffered" away from us. On the other hand, some spurs get through as phase modulation on the bus switches driving the switched capacitor front end. I know this well. I spent months perfecting this ingenious method for escaping the AM spurs and the PM SPURS are what is getting through!! These spurs are annoying and I hope that Gerald in his "next radio" or next generation boards (whatever) finds a way to clean this up. That said, what spurs there are, are way down and on transmit, even with the 100w amplifier these transmit spurs are so far below legal limit as to be not a thing to worry about. On receive, they are annoying because Gerald has built too much sensitivity into the receiver. With everything flaming, he has < -140 dBm as the MDS. This is about 15 dB too sensitive for HF work and of course you can raise the IP3 and BDR WITH A GREAT SOUND CARD by attenuating the front end. With a great sound card, I raised the BDR by 15 dB while keeping the MDS the same even though I put another 6 dB of attenuation inline! I was able to increase the IMDDR by changing the roofing filter (switched capacitor filter values) and increased the IP3 to TOP OF CLASS, BETTER THAN EVERYONE EXCEPT THE IC7800 with a change of front end device! By the way, my sound card cost $1000. SO, you can take your knife and soldering iron and make it a great receiver. NOT FOR EVERYONE! The League recently purchased one for review. Their results will be interesting to see but the K2 will remain the king. I would take away from this discussion that the Elecraft K2 is and will be at the top of the heap in these raw numbers. The SDR-1000 in my view is about 4-th or 5-th on the "Elecraft receiver comparision chart" as it comes from the shop. I can make it almost best on the chart with surgery. So the SDR-1000 is for those who do not mind a never ending beta project. It really is interesting and I have spent hundreds of hours programming the DSP for it along with AB2KT. It is in the spirit of the tinkering amateur radio operator who doesn't mind modifying their existing radio to make it better. SOUND FAMILIAR? On Field Day, I supplied to W2GD, Elecraft K2's for our QRP FD (2A Battery) and we came in sixth overall. I own three transceivers. Elecraft K2, SDR-1000, and FT1000MP. The FT1000MP has not been here for months because it is at my contest multi-multi site (N3NGE's house) as the two meter radio (with transverter). The K2 and the SDR-1000 are fantastic radios but it pays to investigate what is right for you. If you are interested in an open source project that is really interesting and will continue to be interesting for a while, SDR-1000 is a really good radio. It is NOT the "best radio" in what would be most people's estimation. Gerald has been in business for two years and has probably learned a lot from this experience. He has sold over 500 of the radios and has had 5 returned. Three of those folks didn't know they needed a computer! Two of them could not download new software. I don't think he has had a truly disatisfied customer. The SDR-1000 is a real darling of many bleeding edge types in the EME community. It does things others cannot do (some of these ideas stolen from Linrad, etc.) That said, it is a radio in training and Gerald's next offering whatever that is and whenever it will be is likely to be a really nice one. In my mind, the Elecraft K2 is at the top of the heap for best receiver. It never ceases to amaze me that Wayne and Eric put together a kit that continues to put the big boy's to shame. My Elecraft K2 and SDR-1000 sit side by side and they fight daily for my attention! 73's Bob N4HY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] Automated BPL Interference Data Collection.

You probably meant that you cannot digitize, record, process, the entire spectrum on a continuous basis and that I would not argue with, FOR NOW. However, I agree with you that we need to concentrate on the ham bands. We can digitize and entire ham band AND consume it and process it with an eye towards doing some fancy footwork with the information. I suggest you read the November/December 2003 QEX article by my best friend, AB2KT on Automated Signal Classification for Software Defined Radio.

RE: [Elecraft] Automated BPL Interference Data Collection.
I have strong opinions about doing the job with the right tool. A better approach is to do wideband surveillance using more appropriate tools. One could use the GnuRadio/USRP widget or the DCP-1/KD6OZH widget to begin this job quite nicely. Since you really want to demonstrate the impact of the interference on regular operations, the goal would be to have the wideband instruments quickly find likely candidate frequencies for interference content and then, through computer control, tune the narrow band resource do the actual evidence (sound file) capture. Since you are not likely to get really accurate frequencies with the wideband equipment, without needing a huge number of samples and very large FFT's on what will probably not be that coherent anyway, I would think a receiver capable of 40Khz to 80Khz bandwidth would be better. While not inexpensive, the SDR-1000 can be used at that bandwidth. Since we are not really after super performance here, I would think we could get away with cheaper receivers but this would have to be thought out carefully since this is the "evidence" gathering instrument. I would suggest a search strategy doing ham band wide chunks (so you could put some filtering in front of the FPGA based widgets) and have them direct the narrow band resource when and where to record. If we separated antennas sufficiently, and used (say) GPS tamed clocks for the oscillators for the sampling, you could do time difference of arrival geolocation of the emitter. I need ten day weeks and 140 hour days and two more bodies. ;-) Bob N4HY -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Jeff Burns Sent: Sunday, February 13, 2005 1:56 AM To: 'Elecraft List' Subject: [Elecraft] Automated BPL Interference Data Collection.

What is a practical way to get the documentation? I have a few ideas that require programming a computer. I will present them hear in the hope that someone will develop the software. My first thought was to scan through all the HF bands with a camcorder set to look at my transceiver. This way the audio and frequency would be documented. By periodically tuning to WWV, the exact time and date would also be documented. The biggest problem with this is the time required to manually scan the radio. If the process could be automated, data could be collected during all hours of the day, and my time at the radio can be spent making QSO's. - snip -- Jeff Burns AD9T ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

If someone does a private (off-list) reply to one of your messages, a filter built on such a criteria will end up sorting it in with list traffic. I've seen a few embarrassing messages appear on lists as a result of this (responses to private messages ending up on a list). There is a unique header which is present on all messages coming from the list server used by Elecraft, which has been available since at least 2001: "List-Id: Elecraft Discussion List " Depending upon your MUA, "Elecraft" in header "List-Id: or "List-Id: Elecraft" in headers should be sufficient to unambiguously identify a message as coming from this discussion list. I don't know if Elecraft has other lists (a beta tester one, perhaps), but if so, a longer string may be needed to uniquely identify each for anyone on multiple lists. For MS Lookout, a rule such as "Apply this rule after the message arrives with List-ID: Elecraft in the message header" should work.

[Elecraft] Hard Drive Failure, THANKS
I received many many replies from my off topic posting. I love ham radio and the generosity of people to others in need. THANK YOU. My investigations reveal that this would be the single largest expenditure on equipment I have made in two years. Many of you know me, and so you understand what that means: this is extremely expensive. It is that way because companies, having as poor a back up situation as I did, have lost vital data and will pay whatever it takes to get the problem fixed. The market will bear the price, and it is high. My failure is in the spindle and POSSIBLY a disk head. The disk had droppings put on it for ten minutes before I figured out what was happening. I had important family financial, tax, etc. backed up as well as most important code work I am doing now. But I lost a book I was working on, a large article and all research that went into it for QST, a large article and all research that went into it for an article for QEX, a large article and all research that went into it for an article for CQ VHF, and all design work on several antennas including a small vertical array for 160 meters for N2NT and W2GD. It has mostly stopped my work on the SDR-1000 for a month while I attempt to recover. Life is too short and I can afford a full raid disk, and excellent back up, and a high quality UPS much more readily than I can afford to lose exactly 1/10 of my life's work.

Hi It really does not matter with one exception The KPA100 and 60M option require removal of the heat sink on the K2. This is not something you want to do many times because of the possibility of damage to the thermal pads or loss of the hardware stack on the output transistors. I would suggest removing the bottom cover and heat sink once and installing all of the connectors for the KPA100, SSB and the 60M at the same time then you can install the modules when ever you want without requiring the removal of the heat sink. I always install all of the connectors for the KPA100 60M SSB and noise blanker when building a K2 so it is ready for any option with a minimum of disassembly. The connectors come in the option kits so you can fish them out of the packages and install them at the same time you are building the RF board if you already have the options. If you do not have the options yet you can order the connector kit from Elecraft for a few dollars and install them so you are ready for any of the options. If you are going to order the connectors separately then don't forget to order the standoffs and hardware also or you may need to disassemble the heat sink to install the hardware.

RE: [Elecraft] Re: FD W4ZV 1B QRP Single Op
I completely agree with Wayne. Having listened to our mostly CW bands at our QRP FD and looking at the early scores on 3830, comparing them to previous years, I notice almost no decline. Last year, in one of the worst single propagation years I can remember in 30 years of FD (43 for W2GD who agrees), we came within a few hundred points of setting the 3A record. We were behind only the PVRC (23A) and Rochester (17A) in total score. This year we were within 500 or so points of setting the 2A battery QRP record. You cannot do this with a seriously falling density of CW ops because they count 2 points per Q (10 if you are QRP). Anecdotally and mathematically, I believe we can argue that Bill's analysis of what he has heard is incorrect. I love a good argument though, and will listen to any counter remarks with interest.

With that many QSOs, I'm sure you'll do very well in your division. Yes, FD is a bit of work, but it's also a great chance to get outdoors and try your hand at emergency communication setup. I think you'll be back next year ;) > ...seemed to me that the CW bands were surprisingly empty. ... Wow -- that wasn't my impression at all. I heard wall-to-wall CW signals on 20 and 40 meters most of the time, and a good number on 15 and 80 meters. Having done FD for some 10 years in a row now, I'd say that CW activity is about the same as ever. When using QRP on Field Day, you need a lot of patience and the best possible antenna. What I usually do is put up at least two antennas (typically, orthogonal long wires that favor N-S and E-W). You can connect both to the KAT2 or KAT100 at the same time, since both ATUs have dual antenna jacks. You can then quickly test both antennas, even on a per-signal basis, using the front panel ANT1/2 switch. > QSK... Where did you have T-R set in the menu? At T-R = 0.00, the receiver is unmuted very fast, which can cause a small receive artifact with certain narrow crystal filter and DSP settings. But we recommend using T-R = 0.01 or higher anyway. For casual operation, use T-R = 0.02 to 0.05. The time required to cleanly switch the VCO between RX and TX is around 10-15 ms. We put a high value on completely clickless and chirpless CW keying, and adjusted firmware delays accordingly. Still, wiith TR = 0.01, you should be able to hear between characters (not words) even at 50 WPM. If not, you may have an assembly or component problem somewhere. It's likely that we could improve VCO lock time and obtain between-dits receive at such speeds. This is one item on my list of possible future mods for the K2. > Power meter... It's a good idea to adjust POWER when not keying. During transmit, a small additional amount of hysteresis is added to the POWER control to improve noise margin, and this can increase the power-control step size. You can also usually adjust one resistor value in the BFO attenuator to improve power-setting accuracy. Some JFETs (Q24) have much higher transconductance than average, leading to coarser steps from the 8-bit DAC. To compensate, try increasing the value of R98 from 270 to as high as 470-820 ohms. (This experiment is best done with a small trim pot installed; replace the pot with a fixed resistor close to the final pot value.) If you adjust R98's value, make sure that the rig can still reach at least 10 watts on all bands with POWER set to 10.0. > CW messages... In order to store the maximum possible characters in the K2's CW message memories, the firmware "quantizes" your sending into standard-length dots, dashes, and spaces. This is not as forgiving as using a "times-8 clock" for recording, which is characteristic of some keyers. But such keyers have a much larger EEPROM than the K2 does, or they don't provide as many characters of storage. It's conceivable that we could go to a larger part in the future and use a times-8 or even times-16 sample clock.

RE: [Elecraft] Field Day report
Naaa, the thanks all go to you guys at Elecraft. This is one great kit and radio. I love the size and plan on using two of them at the 160 meter contest season during Winter at W2GD (we won Multi-Multi CQ WW this past year). The way we use them, the simplicity and lack of "extras" is a plus. I don't intend to give away secrets here but these radios will be of great benefit to the way we use them. The strong signal handling along with the squeal proofing from being on the same frequency (diodes off the toroidal transformer) as well as the high IP3, etc. will make this radio one superior performer on 160. I am also building the W0UN/W8JI small vertical array at that site and we should be able to hear with the best of them at the end of it. The site is on the Jersey coast in Tuckerton and we are so close to the water that during a Nor'easter last year the bottom of the tower used for the wire BEAMS on 160 was under two feet of water! Thanks for allowing us to have real pride on this side of the Pacific again.

[Elecraft] Field Day report
I hope many of you who did Field Day worked us at W2GD. We had Elecraft K2's on the 2A and a IC-703 on the GOTA station (N4HY). We had a Steppir Beam on 10-20 (15 meters surprised us with a nice opening and accounted for 1/7 of our QSO's). We had a Steppir Vertical on the GOTA station to aid in the isolation (vertical vs horizontal) and it did help. Along with wire beams on 80/75 and 40 meters, we did very well with just under 15 QSO's and several hundred in bonus points. The K2 was excellent. SSB stinks as a QRP mode on FD and we had only 141 QSO's inclusive of the 100 we did on GOTA (N4HY). Lastly, Gary at Elecraft is second as a major resource of help behind the existence of the internet and this exploder. I had a weak receiver problem (finishing the radio at the last minute). It was working but deaf. Gary said it is one of 3 things and the problem was 1st in his list. I would hope that in the future, Elecraft could STANDARDIZE on the transformers, Red wire was ALWAYS holes 1 and 2, and green wire is ALWAYS 3 and 4. After having several that way, the T7 comes along and is the opposite. I was not careful and put it in backwards! The other gotcha for me is reading what to do with the 4.7 pf on the back edge stuck in as a hole filler where a three pin jumper goes. I would change the instruction manual to read: If looking from at the RF board from the front panel side, then left pin is 1 and right pin 3, solder the capacitor into holes 1 and 3. I put it in the pins near the OUTER EDGE, misinterpreting the instructions. The story of discovering this is pretty funny. After Gary helped me fix the T7 problem, it was clear that signal coming through the mixer were much louder. The "birdie" at 7000 Hz used in the initial alignment was much louder and easier to do the alignment of the can. However, the radio was still deaf at the antenna (signals heard but REALLY weak). 8640B set to -40 dBm to produce an S9 signal. I decided to inspect the bottom side of the board again, grabbed the radio on its back edge, and almost blasted my ears off as the receiver came to life. I actually dropped it. I then ran my finger along the back edge until the receiver came to life and then discovered the 4.7 pf in the wrong pins! Great transceiver and a fun kit. I look forward to putting the 160, 60 meter, and DSP in to finish. Bob N4HY ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.

RE: [Elecraft] CW Readers and CW Keyboards.
Do you have a rig interface? Try CWGET, hook it up to your rigblaster, etc. It works pretty well. http://www.softcities.com/CwGet-morse-decoder/download/538.htm Bob -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of [EMAIL PROTECTED] Sent: Wednesday, June 23, 2004 12:28 PM To: [EMAIL PROTECTED]; 'Elecraft Mail' Subject: Re: [Elecraft] CW Readers and CW Keyboards. Hi Larry & group, Don't waste your money. I bought the MFJ 461its very tricky to adjust it to display anything but gibberish. It only works for strong signals of nearly perfectly sent code on an otherwise quiet band. If you can hear other signals near your listening frequency, so can the 461 and it will be "confused", it can't discriminate different tones and lock onto one signal so it won't work on crowded bands. Having said all the above, if you are not put off from buying one.I intend to sell mine on ebay soon.it will have a "buy it now" price of $50.00. You can have it for that price. Its in good shape, little used and I have the instructions that came with it.

RE: RE : [Elecraft] Oscilloscope help part 2 ;-)
Jean Francois: I recently purchased a 4 channel, auto scaling, 400 Mhz Tektronix scope for under $500 US on Ebay and this included 3 probes, two of them 400 Mhz, one 100 Mhz. This is much more capable than what you are talking about. Have your looked there lately? Bob N4HY -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Jean-François Ménard Sent: Tuesday, June 22, 2004 3:27 PM To: elecraft@mailman.qth.net Subject: RE : [Elecraft] Oscilloscope help part 2 ;-) Thanks Ron for your clear answer. I understand, I think this is will be fine for me for now. You know higher they can take, higher will be the price also. This scope is actually around 500$ CDN That the maximum I can affort for a scope for now... But maybe in the futur, I could get a hand on a better scope (maybe a used one) for a good price. Anyway, for now, I think it will be very handy, at least for my understanding of a scope and for basic readings I need. Another good message I will keep in my files !!! Thanks again. ___ Elecraft mailing list Post to: Elecraft@mailman.qth.net http://mailman.qth.net/mailman/listinfo/elecraft You must subscribe to post. Subscriber Info (Addr.
