Eleven New Hams Join the Radio Amateur Ranks

The 2005 Basic Amateur Radio class conducted by the Halifax Amateur Radio Club has seen eleven of its members successfully pass the 2005 Basic Amateur Radio examination this year.  Joining the Halifax Ham community are: 

  • Lorne Burke - ##
  • Andrew Crawford - VE1VAC
  • Wes Dorion - VA1WES
  • Jason Humphrey - VE1PLF
  • Nicole King - VE1NDX
  • Jerry Lockett - VA1YOT
  • Mohammed (Khaleel) Khalelullah - VA1MAK
  • Frank Mallais - ##
  • Ralph Rosere - VE1RAR
  • Ken Rojeski - VE1KJR
  • Bob Schwartz - VA1SCH
  • Terry Myer - VE1DTY ***
## At writing time (April 2005) the call signs for Lorne and Frank had not officially been assigned. Once Lorne and Frank have received their official call sign allocations I will do an update.

*** Terry makes twelve.  Terry contacted the course organizers after the course was well underway and so was too late to register for the 2004/2005 course.  However, eager to get his license this year, he bought the Study Guide and did the work on his own, successfully passing the Basic exam this winter.  So, a special CONGRATULATIONS to Terry.

When you hear these folks on the air, please congratulates them and involve them in your on-air discussions.  We hope that they will all now want to become full members of the Halifax Amateur Radio Club and that they will take an active role in all of our Club's upcoming activities, starting with the Down East Flea Market and Field Day this June.

The following will give you a sense of the diverse backgrounds of these individuals and some of the reasons why they got interested in Ham radio.

Lorne is a Spectrum Management Officer with Industry Canada, working out of both Sidney and Halifax.  Lorne's interest in Amateur Radio was clearly driven by his new job with Industry Canada.

Andrew is a computer programmer and he studied digital electronics in collage.  Andrew is interested in CW and has written software to assist with learning Morse Code.

Wes is an insulator mechanic and a member of the Halifax Ground Search and Rescue Group.  Wes became interested in Amateur Radio because so many of the GS&R team members are Hams, and so much of their communication is carried out on the Amateur bands.

Jason Humphrey is an electronics technologist working with a company at Shearwater.  Jason is also in the military reserves.  His interest in public service and communication in general brought him to the course this year.  Jason also recently completed his CW exam.

Nicole King is the youngest member of the 2005 class.  Nicole is in grade eleven and took the course out of interest in Amateur Radio that she has had since childhood.  Her dad is Wayne King - VE1NR.

Jerry is a freelance journalist and editor.  Jerry is also a sailor and was introduced to Amateur Radio when the Canadian Power Squadron Off-shore Sailing class visited the Halifax Amateur Radio Club Station last year to learn about operating marine mobile HF on the Amateur Radio bands.

Frank is an avionics technician and was convinced by a friend to get involved in Amateur Radio.  It is the communication aspect of the hobby that appeals to Frank.

Khaleel works for a local company in the information technology field.  Khaleel's interest in public service and making new friends brought him to Amateur Radio.

Ken is a retired maintenance engineer, radio operator and radio navigator with thirteen years service in the R.C.N., Air Traffic Control and Marine Communications with the D.O.T.  Ken is interested in using Amateur Radio in Search and Rescue and in general communication with other Hams around the world.  Ken has also successfully completed his CW course and literally "blew the Examiner out of the water" with the speed that he could send with his 'straight key'.

Ralph is an optometrist practising in Dartmouth.  A dentist neighbour of Ralph's took the course recently and convinced him to sign up this year.  Ralph has had a long-standing interest in Amateur Radio but had never made the time or commitment to get formally involved.

Bob is a Canadian Forces Air Navigator and a sailor.  Although his technical background is a natural for Amateur Radio, it was his desire to get his sailboat equipped with Amateur Radio HF gear that brought him into the course this year.


SONRA
The Society of Newfoundland Radio Amateurs 
Serving Radio Amateurs in Newfoundland and Labrador for 46 years.

Born in 1959 - The Society of Newfoundland Radio Amateurs (SONRA) was formed, from the dissolution of the Newfoundland Radio Club. The main purposes of SONRA are to secure the pleasures and benefits of persons interested in Amateur Radio by furthering co-operation among its members, further the interest of Amateur Radio in the community, and provide services to its membership related to Amateur Radio. 

Serving Radio Amateurs of Newfoundland & Labrador - For a number of years, SONRA provided services to all the Amateurs of the Province in the form of a VO Callbook, Call-plate administration, VO Newsletter, just to mention a few, but the growth in the Amateur population over the past few years made this task increasingly difficult. The advent of new regional and local clubs around the Island and in Labrador, plus a shift in the Amateur population density from the Avalon Peninsula area to the remainder of the Province, resulted in SONRA being overwhelmed with the expense of providing the services to roughly 1000 Amateurs from the funding base of a membership of roughly 300. 

A provincial organization starts and falters - As a result, in 1991 the thrust was reinitiated to form a Provincial organization to administer to the entire Amateur population of the Province and in 1994, through the work of Don Wyatt (VO1KX) and Mac Moss (VO1AT), the Provincial organization, VOARA, was formed, taking on many of the provincial responsibilities that had been a part of SONRA's mandate in the past, thus allowing SONRA to be one in a list of many clubs operating to serve its members and general area. Unfortunately, VOARA is no longer actively operating so all provincially-oriented activities, such as the WAVO award, Smallwood Field Day trophy and the provincial call book were returned to SONRA for continued administration.

SONRA has continued to operate and holds meetings regularly. The main thrust of the club is in the area of the education of the Amateurs and the operation of those services which have proved to be of great benefit to not only the membership, but to the community as well.

Currently, SONRA is involved in many facets of the Amateur Radio service to the local community, as well as Amateurs themselves.  SONRA is affiliated with the local Emergency Measures Organization, providing emergency communications when called upon. We are affiliated with Radio Amateurs of Canada (RAC) and support the Incoming VO Bureau. We operate an HF station from the site where Guglielmo Marconi received the first wireless transatlantic signal in 1901 and operate a multi-function station from another historic site, Admiralty House, which was used during World War II as a major communications post for the North Atlantic. We are the only group officially sanctioned to operate special Marconi events from Signal Hill through our partnership with Parks Canada.

SONRA helped make history on June 25th, 1997, as Paul J. Piercey (VO1HE) and Dan Goodwin (VO1MX) assisted Her Majesty Queen Elizabeth II in making the first amateur radio contact by a reigning British Monarch. The contact was between VO500JC, at Cabot Tower in St. John's, NF and GB500JC in Bristol, UK. Martyn Phillips (G3RFX) responded to Her Majesty on behalf of the people of Bristol and amateurs around the World.

SONRA & the Marconi Anniversiary - December 12, 2001 marked the 100th anniversary of the reception of the first wireless trans-Atlantic signal by Guglielmo Marconi. Once again, our club, in co-operation with several levels of government and amateur groups around the world, provided a showcase event while making the historic contact with Poldhu at 1600 UTC. 
 

100 years later we were using technology that Marconi could only have dreamed of; IRLP and contact with the International Space Station.

More information about this event can be found throughout our page.

In the 46 years that the club has been in operation, much change has come to the Amateur world and SONRA has endeavoured to maintain a link to the past while keeping up with the future.   This month, the SONRA membership elected a new slate of Executive Officers.

Five New Fredericton Hams Get Callsigns

Congratulations to the following members of the Fredericton Amateur Radio Club who have just received their callsigns: 

Tony Brayall VE9TB 

Charles Nickerson VE9CN 

David Nickerson VE9DCN 

Jim Ingraham VE9JI 

Colin Ingalls VE9CJI 

If you hear any of these fellows on the air please say "Hello" and welcome them into the Ham fraternity.

Our Youngest New Ham

Congratulations to Caleb Crain who successfully challenged the Basic Exam recently. At the ripe old age of 15, Caleb will be the youngest amateur in our Club. It's really great to see someone of this age taking an interest in our hobby. Caleb is the grandson of Phil Crain (VE9PC) who dutifully transported Caleb to the classes two nights each week for the duration of the course. We're not sure who is more proud - grandson or grandfather.

This means that, with the exception of one student who we believe is out of the country and hasn't yet written, all of our students have now passed the Basic Exam. Thanks to all the instructors and examiners who contributed to another successful course.

SHF 2005 Committee...Hamfest Update

The SHF 2005 committee has undertaken a centennial history project. Through the years, we have noticed a decline in the archiving of photographs and history of radio in our Province. We would like to restore our past and make it accessible for everyone.

Do you have old photographs that you can part with for a while? Can you make us copies?

How about writing up a few pages about what has happened over the last one hundred years in your home area. Anything you can help us with is much appreciated. Please contact the SHF 2005 Committee with any information you can share.

Also, as this is the celebration of the province’s one hundredth birthday, we want to make this the biggest, best hamfest the province has ever seen! Do you have ideas that you would like us to explore? Let us know!

The committee has also developed a survey for gathering input from the ham community. Visit the website, www.saskhamfest.com and fill it out online!

Emergency Preparedness (EP) Week 2005 is from May 1-7 and Emergency Management Ontario is again playing a leading role co-ordinating activities and events. The theme this year is PREPARE NOW! LEARN HOW!

Emergencies and disasters can happen at any time. Utilities can be out, roads closed, and crucial supplies unavailable. While local, provincial and federal officials prepare for emergencies, individuals can plan to be prepared at home and at work.

With increased levels of fear and anxiety throughout Canada and the world, it makes sense to prepare for the unexpected. Everyone should be prepared to take care of themselves and their families for up to three days in the event of an emergency or disaster. For example, it could take that long to clear roads due to a severe winter storm.
 

The following are recommended guidelines to assist you in gathering items you should have on hand. Everyone in your family should know where these items are stored.

Finally, if you are ever in an emergency situation, Don't Panic. People have survived three days without water and three weeks without food. Your home can take three hours or more to cool off completely in the winter.

Operational / Educational

The Sandbox Roundtable Net

The Sandbox Net airs every evening starting at 6:30pm EST on 7.0635  MHz and or 3.732.5 Mhz .. 
Drop in, Say Hello!

The Sandbox Net has been in operation since September 1990, never missing a day, no matter whether band conditions were good or bad. The dedication and the perseverance of Paul Uttaro, VE2QR and a core group of loyal supporters of  The Sandbox Net have made it the number one International Round Table Net on 40 meters. 

    The beginning of the Sandbox Net goes back to June 1990 when Paul's brother Dave VE1TY was transferred to Turo, Nova Scotia from Pointe Claire, Quebec. They set up on 40 meters to just talk and keep in contact every night, soon some friends would join in as well. One of the first was Don  VE3ESE, then came John VE3JWS, Tommy  VE3OIM, George  VE3MMQ, Ed  VE3FE, Roy VE3ALK and many others to follow. 

    By September 1990 the numbers had grown substantially so the group decided to form a net and started kicking around suitable names for it. This went on for several weeks but most names that were suggested seemed to be too long or inappropriate. Since the group were in round table discussions on varied topics, people would break in and say they would be back shortly due to the call of nature. Tommy, for one would announce that he had to go to the "sandbox" and this became the regular phrase when someone had to leave the net for a short period. John VE3JWS, jokingly commented that since everyone on the net were always going to the sandbox, why not call it " The Sandbox Net ". Every one agreed and that is how The Sandbox Net got its' name ! 

The controllers are a varied lot, each bringing  their own brand of humor, thought provoking comments, and by expressing opinions ( of others and their own ) to generate interest and further comments from the round table known as the Sandbox Net! The one thing they all have in common is their dedication to volunteer their time and efforts so that we may all enjoy  this respite from the daily hassle of modern day living.

5MHz (60 metre) Activity Day

Canadian Hams can listen but can NOT Transmit

by

D. Howard Dickson – VE1DHD

I recently was informed that there will be a 5 MHz Activity Day on April 8th/9th 2005. This event has been arranged by Marko Saarela OH2LRDs and they hope to involve other licensed Hams in the EU and elsewhere. For example, there are now 18 club stations in Finland with the 5 MHz license, and Norway received authorisation to use 5 MHz in February of this year. 

Here in Canada, the 5 MHz or 60 metre band has NOT been approved for general use by Radio Amateurs, although it has been approved for Hams in some European countries. However, Industry Canada has given special permission to Joe Craig – VO1NA – of the Marconi Radio Club of Newfoundland (MRCN) to operate on a limited basis on 60 metres for propagation testing purposes. Other Canadian Hams may listen, but are NOT permitted (even if their equipment permits) to transmit on 60 metres.

Joe informs me that the MRCN will be participating in this 60-metre event and that they are greatly honoured to represent Canada and Radio Amateurs of Canada for the 5 MHz Activity Day. At present, they are able to transmit CW on 5260.5 kHz and USB on 5327.5 kHz and
operate a CW beacon on 5269 kHz and so can conduct 2-way 60 metre contacts with any station authorised to transmit on this band. Joe hopes to be able to use all 8 of their authorised frequencies within a week - VO1MRC is authorised to use CW and USB on 5260, 5269, 5280, 5290, 5319, 5400 and 5405 kHz with 100 watts output. 

In terms of propagation reporting on 60 metres, Canadian Radio Amateurs may want to listen on 60 metres during this event on April 8th and 9th and make any SWL reports either Direct or via Bureau to MM1RAH.

Maritime Swap Shop

The Maritime Swap Shop is held every Monday at 7:30pm local time on 3.750 MHz. All station are invited to checkin and post their wants and items for sale. The Maritime Swap Shop list can be found on many places on the internet, here are just a few: The Loyalist City Amateur Radio Clubhfradio.net ,    VE1AIC's Home Page  and  Truro Amateur Radio Club

Please Note: The Maritime (on-air) Swap Shop, which was formerly held on Tuesday evenings, will now take place on Monday evenings at 1930 local time on 3750.



 
Looking for that special piece of radio gear to finish off your ham station? Do you have extra radio gear you'd like to turn into some cash? 
Well the place to visit is the 'Ontario Swap Shop' held every Sunday at 12 noon on 7055 kHz and 7:00pm on 3755 kHz. Nick VE3NJG and Ken VE3YK host the hour long program and all amateurs are invited.

The Swap Shop list is posted every Monday on the Trans Provincial Net website, Ontario Swap Shop Listings , the swap shop list can also be found on packet by calling up VE3DID

Feature Articles 

Father and Daughter Ham Team
by
D. Howard Dickson - VE1DHD


Nicole (Niki) King - VE1NDX - is the latest and youngest graduate of the Halifax Amateur Radio Club 2005 Basic Ham Class.  She joins father Wayne - VE1NR - a long-time Maritime Ham, DXer and contester, in the Amateur Radio fraternity.

Father Wayne tells me that he was attracted to radio from a young age, and like many Hams he started out by listening to short-wave radio and then growing from there. In fact, Wayne still has his first receiver - a Heathkit GR-64, which he and his dad built when Wayne was but 15 years old.

Wayne received his license in 1981 and obtained Advance status a little over a year later. 

Nicole, with proud father Wayne King at the HF radio in the Halifax Club Station minutes after being told that she passed the Basic exam.
As a ham, Wayne has been involved in many aspects of the hobby from president of the Dartmouth Amateur Radio Club, to working with the Telephone Pioneers. For many years his main passion was chasing DX and has enjoyed a number of opportunities to work DX from Sable Island ( CY0 ) off  the south-east coast of Nova Scotia.

With his deep passion for, and involvement in Amateur Radio, Wayne's children couldn't help but be exposed to the hobby all their lives.  Wayne tells me that he is so very pleased to have his youngest daughter Nicole joins the Amateur Radio fraternity. And while Wayne's wife and Nicole's mom has always been understanding about the hobby he loves, she has never had the desire to become a Ham. 

I first met Nicole in September of last year when she arrived at the first of our Basic Ham classes, and I was impressed both by her keen desire to learn and by her dedication to the hobby.  I think she only missed one or two of our weekly sessions and then because of school work.  As a former teacher I can understand that!

Nicole tells me that from a very young age she has been listening to the sounds of numerous voices coming across the airwaves, and crackling through the two-meter radio in the family car as the family drove to some destination or other.  As Nicole tells it, it was always, "Ssshh.. daddy's going to talk on the radio now."  In fact, as Nicole says, "All my life my father has been a radio amateur operator and now I have become one too." 

Nicole is an eleventh grade student in Halifax, and has been exposed to the vast world of amateur radio for all of her seventeen years. She tells me that it was about four years ago when she first started to get really serious about becoming a 'Ham'.  However it took a few years of "bugging her father" before he realized that she was serious and he then eagerly arranged for Nicole to join our class.

As I said, Nicole was a great student and she passed the Basic exam with flying colours, and is now so pleased to be able to "follow in my father's footsteps."  As Nicole puts it, "I have always enjoyed the hobby as a passive listener - I'm just so used to listening to the sometimes awfully distorted noise of other people's voices, and the laughter when my dad spoke to them, and I really wanted to be part of his Amateur Radio world, making contact with different people around the world.   Now I am getting that chance and I am so proud to say I am a Radio Amateur Operator. "


CNIB AMATEUR RADIO PROGRAM

George Fanjoy VE3PEB
Chairman CNIB Amateur Radio Program

Dear Fellow Amateurs:

Kelly Sapergia’s (VE5KJS)  hobbies as a child were music and  computers. When he was 14, friends in his home town of Moose  Jaw, Saskatchewan, introduced him to ham radio. He’d always been a radio listener, especially shortwave, so being able to chat to people over the radio had great appeal.

Blind since birth, Kelly found ham radio to be a great way to make friends all over the world. He remembers his first international calls, when he picked up signals from Italy and Hungary: “It’s so exciting to get a contact from another country.”

Getting his ham radio  licence was a group effort. The  CNIB provided training courses on  cassette, and with coaching from  other hams, he easily passed his  exam. He then bought a radio through the CNIB, which he paid for through installments. “I still have that radio and it’s a dandy,” he says.

Kelly remembers certain  conversations like they happened  yesterday. One was the Moose Jaw flood in 1997. He remembers the chill of hearing another operator yell, “Oh my God, the bridge is going out!”

Kelly’s been part of his  local Amateur Radio Emergency Services since he was about 17.  On Halloween, he sets up his command post at the local police station and other ham radio operators patrol the streets, radioing in any problems to Kelly, who notifies the police. Operators also sometimes help motorists in distress and pass messages in weather emergencies.

The article above will be made available to blind and visually impaired CNIB clients from across Canada in the Spring 2005 Vision magazine.

We count on clubs such as yours to support us in helping members such as Kelly. We are  pleased to receive individual  donations of money or equipment as well as your club’s donation. We will provide income tax receipts and credit such donations  to their Club for the Club award  program. Donations of equipment  and money are also welcome from 
estates.

The German Navy, U-Boats & Magnetic Antennae 
by
Bill Galloway - VE1WWG

Introductory comment by VE1DHD -
 

 We Hams are all too familiar with the electric component of the electromagnetic (EM) waveform, and we don't very often, if ever, remember that the EM waveform actually consists of two wave elements at right angles to one another - one is the electric component and the other the magnetic component - thus the term electromagnet. In Amateur Radio, almost all of our antennas are designed around the electric component of the EM wave.  Bill Galloway - VE1WWG - is the one person that I know who has actually designed and built HF antennas based on the utilization of the magnetic component of the waveform. 
Fig. 1 - Electric (E) and Magnetic (B) components of an electromagnetic waveform. 

 The majority of the following material was taken, with permission, from the website of Bill Galloway - http://www.bill.gallowaysystems.com/index.html

Background:

Back during World War II, the German Navy U-Boats were having great difficulty communicating with their Headquarters, which I think was in the heart of Germany. 

In order to communicate they had to surface. That in and of itself was very risky in enemy waters. However, it was mandatory that they communicate because that was the way their orders and order changes were received. To get around this problem of surface vulnerability, their research people came up with a clever idea that would allow the U- Boats to communicate while still submerged, and that was the beginnings of the Magnetic Antenna. 


Fig. 2 - Schematic of Magnetic Loop Antenna.

If we submerge an ordinary dipole antenna in seawater, you will very quickly realize that it just won't work. The seawater being very conductive causes the antenna to be unusable. A dipole operates with a very high intensity electric field as the basis of transmitting. With conductive seawater all around the antenna, the Electric Field coming off a dipole would be attenuated to nothing in short order. 

The German Navy therefore needed an antenna that would not use the electric field as the basis of transmission, but instead the magnetic field. The magnetic field would not be affected to the same degree by seawater as the electric field. And so, the Magnetic Antenna was born and it has been in use ever since. 

Basic Antenna Design and Function:


Let's take a more detailed look at both types of antennae -- Electric and Magnetic. 

When I made a presentation to local Ham Clubs on this topic it was at this point that I would draw a simple Dipole Antenna and proceed to describe how the electrons flow on the antenna during both positive and negative portions of an RF cycle. I would show that during the first half of a cycle, the electrons flow in one direction. They would then flow in the other direction during the other half cycle. I would then plot the Absolute Voltage and Current Levels on the Dipole. This would show that the Electrostatic or Electric portion of the RF Field is generated by the high voltage levels at the ends of the dipole. 

Fig. 3 - Taken from ON4CEQ http://home.paonline.com/dsarraf/Mag_Loops.htm
The small loop at the back is a one turn loop that was made from 75 Ohm TV Coax 

The larger loop in the foreground is an octagon loop in 15mm copper tube with a circumference of  4.8 meter (16 feet).   The biggest problem is the tuning capacitor, if you transmit with a power of 100 W you need a capacitor with a voltage rating of 5000 Volt. ON4CEQ built his own butterfly capacitor because the losses are lower than a split stator. The capacitance is 5-65 pF and the voltage rating is 7200 volts.
 

The Electromagnetic of Magnetic portion of the RF Field is generated by the current flow near the feed point of the dipole. 

I would show that the strength of the E-field near the dipole is very high relative to the strength of the H-field or magnetic field (shown as B in Figure 1 above). Specify that as the field moves away from the antenna, the strength of the E-field increases somewhat and the strength of the H-field decreases to achieve a ratio of E to H of 377:1

A Dipole antenna can be classified as an Electrostatic Dominant Antenna, or just simply an Electric Antenna. A Magnetic Dominant Antenna is called a Magnetic Antenna. 

Why a Magnetic Antenna?
Magnetic Loop antennae are special because they pick up only the MAGNETIC portion of the ELEKTROMAGNETIC radio wave. The big advantage of this antenna is that electric interference from the big city (streetlights, televisions, cars etc...) have absolutely no influence on the received signal. With the loop you can hear other stations that you can't hear if you use a DIPOLE, because with a dipole the stations are buried in the 'electric' noise.
 
 

Magnetic Antenna - Let's look first at the design fundamentals of a Magnetic Antenna. Firstly, the resulting magnetic field must be bolstered or increased. This is simply done by forming the conductor into a loop or coil 

(Fig. 2). The magnetic lines of force are now more concentrated. By doing this, the antenna has increased inductance. This can be overcome by putting a capacitor between the two ends (which are adjacent to each other) and tuning the inductance and capacitance to resonance at the desired frequency. The Electrostatic field will mostly be contained in the capacitor and therefore, because it is in such a small area, is not the dominant field. 

Fig. 4 - A long view of the loop. You can see the two pipe turns and the coax feed loop clearly. The two trombone capacitors are mounted on a piece of hardwood. The two motor/gearbox assy's are at the 2 ends.  The larger, band-change capacitor to the left and behind the loops, and the smaller, intra-band tuning capacitor to the right in front of the loops.

To be more specific, the Magnetic Antenna is a loop whose circumference is 1/4 wavelength at the operating frequency. For 14 MHz 1 wavelength is 300/14 = 21.216 m. 1/4 wave length is 21.216/4 = 5.304 m. The diameter is 5.304/3.14159 = 1.688 m. 

A Magnetic Antenna can be tuned from the designed frequency frequency and still maintain acceptable efficiency. 

A word or two about Radiation Resistance. 
It is a concept rather than something real. When you feed energy into an antenna, some of it is lost as heat across the actual resistance of the antenna. The remaining energy that is radiated is said to have been dissipated across the radiation resistance.  The radiation resistance of a Magnetic Antenna is very low. With that in mind, the actual resistance must be kept as low as possible so that it does not dissipate most of the input power as heat. To achieve a very low actual resistance the Magnetic Antenna coil or loop is made of copper pipe. This material is ideal because it is readily available, low cost, and RF only travels just below the skin anyway. 

Now we come to the capacitor 

A capacitor of a Magnetic Antenna must withstand very high voltages. For a 100W transmitter, the voltage at the capacitor could reach over 4,000 volts. Another requirement is that it must not have any sliding electrical connections. The capacitors that will meet this requirement are the Butterfly multi-plate capacitor and the Trombone or Piston capacitor. The later can contain the electrostatic field quite well, in fact better than the Butterfly capacitor. 

The Feed System - To make the Magnetic Antenna complete we need a feed system. There are two methods that I know of -- the Gamma Match and the Faraday Shield Loop. The most common is the Faraday Shield Loop -- referred to as a "Primary Coupling Loop"in Fig. 2 above. It has a diameter 1/5 that of the larger loop. It can be constructed using RG213 or RG8. I have even used RG58U but the physical strength of this type is lacking. 

The shield of the Faraday Shield Loop is electrically connected to the electrical centre of the large loop. At the top of the Faraday Shield Loop the shield is terminated to expose the inner conductor. At this point the inner conductor is electrically connected to the shield of the remaining half of the Faraday Shield Loop. At the end of the loop both the shield and the inner conductor are electrically connected to the same point where the Faraday Shield Loop started. 

Fig. 5 - An even closer view of the central area. You'll see that I've mounted the whole thing on a nylon bread board for stability and convenience. 

Fig. 6 - This view is a close up on the trombone capacitor used to tune inside a band. It is about 5/8 withdrawn. This view also shows the rotation motor/gear-box assembly. The whole antenna is supported from the roof. The board that the rotation motor/gearbox assembly is mounted to is actually not touching the circular disk beneath. There is a pin (large nail) centering the loop assembly over the disk and the rotation motor/gearbox assembly drives a small grooved shaft around the outside of the disk imparting rotation to the antenna. 

The Transceiver must be connected directly to the Faraday Shield Loop. Tuners must not be used. 

The other type of feed system is the Gamma Match. Here the shield of the coax is electrically connected to the electrical centre of the large loop. The inner conductor of the coax is electrically connected somewhere along the large loop to obtain a 50 ohm match once the antenna is in resonance at the operating frequency. 

Tuning the Magnetic Antenna is done by adjusting the capacitor so resonance is achieved at the operating frequency. Magnetic Loops are fed with unbalanced co-axial feeders. Until the capacitor is tuned to the correct transmit frequency the antenna will not resonate, and cannot be loaded properly. Once tuned however, the smaller loop used to load the antenna then needs to be positioned to effect a 50-ohm match. Any mismatch will result in standing waves on the coax cable, which in turn will radiate and reduce one of the advantages of a magnetic loop - its narrow band-pass filter effect. So in other words, adjust the tuning capacitor to obtain resonance of the antenna as indicated by the lowest SWR. If the SWR isn't 1:1 the smaller feed loop will have to be deformed somewhat. Deform the smaller loop by forming it into an ellipse for example. You will notice a corresponding change in SWR. Once the 1:1 SWR is achieved nothing else will have to be done to the feed loop. You now have a tuned loop, and have positioned the smaller driver loop to get a 50 ohm match, you can retune the transmitter and main loop without having to worry about altering the driver loop - the 50 ohm match works for all resonant frequencies without further adjustments. 

I found greater success using the Faraday Shield Loop feed system. The Gamma Match feed system tended not to have optimum VSWR on all bands and it has more noise pickup than the Faraday Shield method. 

I made a Single Turn Magnetic Antenna as a test of different capacitor types and achieved success right away. I was sold on the idea when it was just as good as my Telex Vertical but with a much lower noise figure. 

You may physically place the Magnetic Antenna almost anywhere and it will function quite well. You don't need to be high above the ground. For that matter you can place it on the ground and it will perform well. 

The Magnetic Antenna operates best when it is mounted vertically. The wheels of a vehicle are in the vertical plain. If you look through the "hole" in the middle of the loop, you are looking along the only point of a Magnetic Antenna from where there is no radiation - a Null. The maximum radiation is 90 degrees to the null or off the ends of the loop. 

As was mentioned earlier, the Electric field near the Magnetic Antenna is very weak whereas the Magnetic field is strong. The further away you get from the antenna the stronger the Electric field becomes and the weaker the Magnetic field becomes. At around 2 or 3 wavelength from the antenna the ratio of Electric and Magnetic field strengths is 377:1. 

A Magnetic Antenna -- the practical solution to a difficult situation. I wanted to have a Magnetic Antenna in my attic that would cover the 20, 30 and 40 meter bands. The problem is my attic is only 35 inches high! I decided to make a two turn loop which put both the feed point and the capacitor at the bottom. 

A great number of questions needed answers after determining the physical aspect. Questions like, what is the total overall length of copper pipe needed, how far apart will the turns be, how do I tune within a band and how do I tune from one band to another, what size of capacitor(s) do I need, how do I feed the two turn loop. 

I decided to make the total length of pipe somewhere around 15 feet. That value was mostly determined by the physical size the antenna must be to fit in the attic in a vertical plane. I made it up using a kitchen cutter board at the bottom to hold everything there solidly in place. I wanted to use a Trombone-type capacitor to tune it. I performed numerous tests and came up with a design that met my needs. After putting it together without the feed loop, I used a dip meter to determine its self-resonance point. It was just above the 20-meter band, which was great. If it hadn't been, I would have adjusted the spacing between the turns to increase or decrease the capacitance. I ended up with approximately a 2-inch separation between the two loop turns. 

I pushed the Course Trombone capacitor in slowly, tracking it down in frequency until I got to the low end of 40 meters. That was good. I added a Fine Trombone for tuning within bands, leaving the Course Trombone for Band changing. 

I used the Faraday Shield feed loop design. Since it should be 1/5 the circumference of the large loop I decided it should contain 1/5 the length of pipe for the two turns of the large loop. That resulted in about 3 feet.

With the Antenna installed and the feed loop in place it was time for the first test. The SWR was terrible, everywhere. I deformed the feed loop to be approximately 16.5 inches high and 5.5 inches wide. The resulting best figures for all three bands are as follows:
 

Frequency SWR Rs Xs Z
. . . . .
14.3 1.1 57 6 58
14.2 1.1 54 2 54
14.1 1.1 54 3 54
14.0 1.1 54 3 53
. . . . .
10.150 1.5 73 17 75
10.100 1.5 75 11 79
. . . . .
7.1 1.6 37 20 43
7.0 1.7 44 28 ??

Bandwidth on all bands at the SWR of 2:1 points: 70Khz. 

As far as performance is concerned, I tend to use it all the time. As compared to my Telex Vertical, it has a much lower noise figure, Some signals are the same strength on the S meter as the Vertical, and some are less. Reports back indicate that my signal strength is satisfactory. I don't see any difference with the Vertical

My Magnetic Antenna is but inches from the household power lines and alarm system line. It doesn't get into either. It doesn't get into anything in the house.

CF3VEDAY
by
Bob Cooke VE3BDB


 CF3VEDAY is the call sign of an Amateur Radio special event station operating under the authority of the Canadian Government from May 5 to May 11, 2005, inclusive.  Holder of the call is Robert Cooke, VE3BDB. 

The call was kindly issued by the Amateur Radio Service Centre of Industry Canada and we extend sincere thanks to Jim Dean, VE3IQ, Vice President Regulatory Affairs Radio Amateurs of Canada for assisting in its issue.

The purpose of the station is to mark the official opening of the new Canadian War Museum in Ottawa, the national capital of Canada, on May 8, 2005, and coincidentally, the 60th anniversary of Victory in Europe Day -- VE Day -- which, on May 8, 1945, officially ended the Second World War in Europe.

 What's more, the year 2005 has been declared Year of the Veteran by the Canadian government.  The sacrifice and determination of Canada's WW II veterans is hereby being recognized and applauded. 

     The station is operated by members of The Wireless Set No. 19 Group, a Canada-based world-wide group of Radio Amateurs who collect, restore and/or operate vintage military communications gear.

     This website [ www.qsl.net/vc3vday ] will compliment the CF3VEDAY station by providing information about station operation, including times, frequencies and names of operators. 

     The month of May will see the official opening of the new Canadian War Museum and this station will also conduct on-air activities from Ottawa to mark that event, using vintage military equipment.

       Amateur Radio operators are encouraged to invite a veteran into their shacks to allow contact with other veterans and to have contact with CF3VEDAY during its brief existence.  They may even hear the "chirp" of a WS#19, renewing old memories for some.

    Radio Amateurs could also consider inviting young people in to view and use their radio equipment, to learn more about the stellar contribution of Canada's war veterans and to demonstrate what Amateur Radio is all about.  This in itself could be a valuable history lesson to those persons under 65 who have no memory of, or appreciation for, the historic contributions of Canadians during a bitter fight against tyranny on the sea, on the land and in the air.

     We will be offering an original, colourful QSL card to all Amateur Radio stations that contact and send a QSL card to CF3VEDAY, as well as to SWLs who hear the station and who submit a full reception report.  Please read the QSL/SWL report information: www.qsl.net/vc3vday/
