CONDOLENCES to Steve, VE3KC , and Nancy Cutway on the passing of Steve’s mother, Norma, on May 6, 2006. Mrs. Cutway had been ill for several months. There is a new repeater and it is using the call sign of the late Cliff Ireland VE3HTN. It is located at Toledo, Ontario. Frequency is 146.865 –600 and can be heard in Kingston. Kingston Amateur News Page 3 (For those who were unable to attend the Memorial Service for VE3NB, Bernard Burdsall, who will be genuinely and sincerely missed, the following is the Eulogy composed and presented by VE3UIN, Drew Wollin.) IN MEMORY OF VE3NB, BERNARD BURDSALL If you knew Bernard, you knew that he was an Amateur Radio Operator. Ours is a hobby that many would call a second career. The word Professional is used to describe a person with the qualities of service making expertise available to others, and based on a distinctive body of knowledge and skills underpinned by abilities and values. And in this Bernard was a consummate professional. Bernard was first licenced in 1938, after a brief encounter with a radio inspector. He shared this story with us in a recent issue of our club magazine, and showed that his fascination with the magic of radio began at an early age, in the company of friends and with the help of local experts. He was telling us of the best traditions of our hobby with this story, and that he still cherished it 68 years later. During the Second World War, he used his talents as one of the legions of British amateurs who monitored transmissions from Europe to feed the code breaking effort at Bletchley Park, and later as a radio operator in bomber command. Bernard was well known for his organizational and leadership skills. He could get groups of people to pull together often with a little cajoling and always looking for a better way to do things. We found ourselves leading ourselves, with Bernard right there with us. These days we call this ‘Empowerment by Example’. He served as Treasurer and General Manager of the Canadian Amateur Radio Federation, our hobby’s first national body. Bernard would have wanted Amateur Radio in Canada to have a distinctive Canadian approach. He was often at the CARF offices on King Street, stuffing envelopes or guiding the Canadian Amateur Journal. He wrote many times for the Canadian Amateur, as well as serving in various editorial roles and as a Director of CARF publications. When the new Radio Amateurs of Canada replaced CARF, he worked as a columnist, and continued to be a fixture at the RAC offices in Kingston, always helping get mail out, guiding and writing. He remained involved with RAC when they moved to Ottawa helping and commiserating with their General Manager. It was locally that his efforts were felt most often. He was a wealth of information and technical skill. He was a founding member of the Kingston Amateur Radio Club in 1947. He often served as Treasurer or Secretary in the club, as well as organizing field days and the club’s very successful flea markets at St. Margaret’s United Church Hall. He was the President of the club in 1958, but I think that he preferred to be part of the leadership, rather than being the boss. Kingston Amateur News Page 4 He was the sponsor for the local repeaters, which, with others he had built when repeaters were the new thing. And he helped keep them running for decades. Local amateurs have told me of the many occasions when Bernard would repair a radio for them that had defied the efforts of a service shop. He built radios for newly licenced amateurs under a program of the Canadian National Institute for the Blind and repaired their talking book machines. ANYTHING TO HELP OUT. Much of what Bernard did was about service to the community. He was a driving force in the local chapter of the Amateur Radio Emergency Service. It was in this vein that I came to know Bernard. As a recently licenced amateur, I joined the local radio club and ARES. Bernard looked after the equipment for ARES. As a group, we would get called over to the Burdsall residence to test the generators, try a few new things, and generally learn more. On my first visit, I was struck by the organizational skills of the man. In this regard, he was my opposite. Everything he had was labeled, accompanied by a zip lock bag of spare parts and manuals, simplified instructions and service logs, everything had its place, and always worked. There was always a project on the go. I also noticed that everything had a handle. When I finally asked him about that he told me that this was to make it easier for his wife to carry. It was only when I caught a slight glint in his eye and the hint of a smile that I knew he was pulling my leg. That was Bernie, teaching with humour, and always keeping you a little off balance. “Never do to be too comfortable,” he’d say. He gave many presentations to our group, on a bit of history or a new idea. And every Christmas he made sure we had some refreshments at the meeting. No meeting went by without an extra prize for the draw, even when he couldn’t attend. The Burdsall home was the meeting place of choice. Visitors were welcomed with tea, coffee and a never ending supply of Peek Freans cookies. Many good ideas came from the relaxed comfort of their dining room, and many new or prospective amateurs have been welcomed to our hobby there, learning that while we get together to share the wonder of radio, that it’s all about people. Bernard told me of calming the nerves of a prospective licencee with a cup of tea. Often too nervous to pass the Morse Code test the first time, Bernie would pour them a cup and then send a little on his key. In no time there was a new amateur, now much calmer. These are some of the things that have endeared Bernard to us. On behalf of the Amateur Radio community, I express our deepest sympathies to his beloved wife, Margaret, and his great family. We shall miss this remarkable husband, father and friend. 73 Nancy Baker Kingston Amateur News Page 5 REMEMBRANCES OF VE3NB, Bernard (from conversations and e-mail) I remember being along with Bernie in 1982. We were supporting the 1000 Island Rally put on by the St Lawrence Valley Auto Club. I was still a SWL, not yet licensed. Bernie and I were working 80m mobile using military surplus rigs and were out for about 36 hours. There were a number of trips to Garden Island in John D'Esterre's boat. I don't remember that we did a lot of operating but we always had a great day. There was a debate about whether Garden Island was a legitimate Island on the Air candidate, but that wasn't really the point. Bernard was VE3BEO when I met him. He worked as the treasurer for CARF for quite a while, often in the office doing what needed to be done. He often wrote for the TCA. VE3GO, Ron ******************************************* The first Club meeting I attended was in December 1972. I was taken there by my doctor, the late Peter Smith, who thought I would enjoy the hobby. I was immediately connected with Bert Hovey VE3EW and Bill Bushell VE3DXY. They told me that Bernie would likely be involved in building my Heathkit radio, a Hotwater 12, which were made available to "white caners" by the CNIB Amateur Radio Program. He did indeed build it after I got my license in March '73. But in December '72, he and Margaret held a post-Christmas party for Club members and partners and Nancy and I were invited even though I wasn't yet a ham. We couldn't have been made to feel more welcome if I'd been a ham forever! I will always cherish the memory of that party and Bernie and Margaret's kindness. I was practically a kid and other than Bernie's daughters, the youngest person there. Steve Cutway, VE3KC ******************************************* Bernard told me of the first repeater the club put up at Elrond Tower. It operated without a duplexer. The receive and transmit antennas were isolated from each other by the building itself. That made the transmit coax quite long. One day the repeater stopped responding. Bernard checked the swr and found it fine. Puzzling over the problem, he went to check the antenna and found it missing. The transmit coax was presenting a good match without any antenna at all. He often shared stories of his work with Bell. One was a simple a description of how the microwave link that joined the country operated. I was amazed to find out that those huge horns and dishes operated at such a low power, it was all antenna gain that made the system operate. VE3UIN ******************************************* Kingston Amateur News Page 6 I remember when we moved the repeater to its current location. He had been fighting intermod at the John Orr Tower for a long time. When we got the repeater working at McAdoo’s Lane, he measured the receive current and found no signal. He told me, it's not working. I tripped the repeater with a hand held. He was astonished. He was so used to seeing an interference level on the receiver; he couldn't believe it when he found that the new site was so quiet. Tom, VE3UDO/VA3ZE ******************************************* Although I have only known Bernard for a relatively short time, I have valued his wise counsel and wealth of experience. He was always there when we needed him. He contributed in a positive way to ARES, whether giving a talk at a meeting or just a friendly word here and there. Bernard epitomized the spirit of a volunteer always available, always willing and always one step ahead of the herd. I will miss his very dry, very British sense of humour. It enlivened many a conversation. We are the poorer for his passing. R.W. Ellis/VE3RXE Emergency Coordinator Kingston & Area Amateur Radio Emergency Services ******************************************* I just received some bad news *SILENT KEY* *VE3NB Bernard Burdsall died this Sunday morning* Bernard was a staunch supporter of Amateur Radio, RAC, and one of the founding members of KARC. He will be missed by all of us. VE3NFU Bill Mason ******************************************* This is very sad news indeed. I really enjoyed talking to Bernard and especially his quick wit and humour. He also was a great source of knowledge. We will all meet again, Robert VE3RPF ******************************************* Received both of your messages Bill and very sad news. A terrible loss to all. Bernard's quick wit, vast knowledge and very generous help will be greatly missed. John, VA3GST ******************************************* Kingston Amateur News Page 7 SOLDERING ON VE3VJF Roy Saturday, May 20th dawned dull and overcast. By lunchtime we were into the rain. A perfect setup for a soldering course that VE3RPF, Rob Parker, held at the Kingston Airport, thanks to VE3NWV, Barry. The eager beavers arrived carrying various things including magnifier lamps. One would think this was going to be a dentists’ convention. With power bars arranged everywhere, things soon settled into a more work-like atmosphere. We were soon into the do’s and don’ts of soldering and emery paper was a definite NO, NO. We were going to build a 15 watt power amplifier. This is a kit put out by ‘Future Kits’. For a ‘non tech’ things started to look good and we were soon into cleaning the ‘board’ with a really sharp looking white eraser along with Q-tips and cleaner. Soon the aroma of hot soldering irons was in the air and by now I was thinking like a watch maker, “Can’t see.” Now it was, ‘the smaller the better’ as one was required to have the touch of a midwife to continue. My upward glance along the table saw all heads bowed, not in prayer, but really into it! Soon we started making sense of all the very small pieces that have to go somewhere. Not knowing the colour code didn’t help but under Rob’s tuition things ran along smoothly. As the afternoon rolled along we soon came to, “Let’s test it” before we install the I.C. I soon discovered that, yes, I had something in backwards so it was back to the drawing board to get help to fix it. Once again, up front, to get it tested and by golly I made it. Next, to finish off the job, the heat sink had to be screwed on. With various small adjustments, all the ‘students’ accomplished what they set out to do – build something that works and they can use in the future. From the satisfaction that everybody achieved I would like the club to put on more of these projects. I, for one, found it very educational. • VE3RPF, Rob’s Soldering Course. We really did work. Kingston Amateur News Page 8 DSP versus Crystal Filters VE3OL / VE3KGJ, Bill I have been curious about the performance of my IF DSP receiver as it compares to my crystal filter rigs. So I ran a few tests and these are the results. Test Equipment: Elecraft N-gen, wide band noise generator (http://www.elecraft.com/) Spectrogram software (http://www.n0ss.net/) Version 5.17 is the last full featured free version. Newer free versions are available but they limit the time that you can use them and are not as easy to use as version 5.17 Receivers Tested: Ten Tec OMNI VI/opt 3 with 2.4 khz ,1.8 khz and .5 khz filters Ten Tec Argonaut V (IF DSP, variable from 3.0 to .200 khz) Test methodology: The noise generator was attached to the receiver (antenna) input and the audio band pass was measured using Spectrogram software. I then used screen capture software to capture the screens for publication. OMNI VI/opt 3. Standard 2.4 khz filter Kingston Amateur News Page 9 Optional 1.8 khz filter Optional 0.5 khz filter Kingston Amateur News Page 10 DSP Filtering with the Argonaut set to 1.8 khz bandwidth DSP Filtering with the Argonaut set to 0.5 khz bandwidth Kingston Amateur News Page 11 DSP Filtering with the Argonaut set to 0.2 khz bandwidth As you can see IF DSP closely mimics the performance of crystal filtering but the slope of the filter is not as steep. On the other hand with a variable IF DSP you can close down the filter to compensate for this. You will notice that I mention only IF DSP filtering. Audio DSP filtering works very well and there are quite a few add on AF DSP filters on the used market that give a good accounting for themselves. BUT AF DSP filters suffer one major disadvantage. Any strong signal within the receivers crystal filter bandpass will cause the AGC to pump. This can cause problems if you are trying to listen to a weaker signal. Some rigs like the FT-857 us AF DSP and they suffer the same characteristics as the add-on units. Using the IF shift can eliminate some of the strong signals but as you will see later…. How many knobs do you have to diddle? I am very curious as to what the new ICOM 7000 or the other advanced IF DSP rigs are like. From my investigation as shown above I think they will make a very good accounting for themselves and of course they eliminate the need to buy all of those expensive crystal filters to improve performance. I have used add on DSP filtering. I have had a MFJ 784, a Timewave DSP 59+ and a Radio Shack DSP filter. For my operating style both the MFJ and Timewave units suffer one major drawback; too many knobs to fiddle with and not enough information from the unit. For my money the Radio Shack DSP filter, which is available used for as little as $20 is the pick of the litter. It is simple and easy to use but it suffers from one major drawback. On CW it is set to a 750 hz tone. Non-adjustable. I prefer 650 or 700 hz. The advantage of the RS unit is that it has a built in speaker, eliminating yet another wire snaking around the operating desk. I was fortunate to have a Timewave DSP 599zx loaned to me for a few hours to play with. Now here is an addon DSP filter with a difference! This unit has a digital display to tell you the center frequency, bandwidth and many other features that make it a joy to operate. But this comes at a price. Over $600! It is the Cadillac of them all.
