Early SARC History

SURREY AMATEUR RADIO

(1975-1981)

The Surrey Amateur Radio Club had its beginning in the Electronics Lab of the North Surrey Senior Secondary School in the spring of 1975. In a discussion with electronic students who had recently been successful in obtaining their Amateur Radio Licenses, the idea of a local radio club was put forth. Cory Balbraith, VE7CGR, liked the idea so much; he spread the word far and wide via the airwaves. It was so well received that plans for a fall start gathered momentum.

The electronics instructor, Doug Moore, VE7CBM, was granted permission by the administration to hold meetings in the electronics room on Tuesday nights. Incidentally, the club held their meetings and theory classes on Tuesday s for the first two years before switching to Monday nights.

The initial meeting was held on the first Tuesday in October 1975. Many members of today were present at that meeting. As Doug, VE7CBM, had to the key to the school, he was quickly elected President, with Cary Miller, VE7CFC, as Vice President and Cory, VE7CGR, as Secretary-Treasurer. The duties of the President were threefold; open up the school, chair the meetings and make sure there was coffee and cookies available.

In January, Cory graduated and went to Nanaimo to work for radio station CHU. Fred Orsetti, VE7CJG, was elected to take over the duties of Secretary-Treasurer.

The theory lessons began in December with Bob Searle, VE7CHB, Cary, VE7CFC, Fred, VE7CJG and Doug, VE7CBM, all helping out. Over the years, several members gave their time and energy to teaching the theory Garreth Gammon, VE7CGG, Lee Middleton, VE7BHS, to name a couple. Mike Holly, VE7AVM, was instrumental in making tapes and teaching CW for several of the beginning years.

The club had access to the school's Kenwood 510 but was never able to make use of it for various reasons.

Our windup to a very successful first year was the Field Day held at Fred's QTH in June 1976 and supervised by Mike, VE7AVM. For the majority of members, this was a first. We didn't do all that well but enjoyed the outing and fellowship. Those involved were Mike, VE7AVM, Cary, VE7CFC, Carl, VE7CLC, Mike Heritage, VE7CLE, Ed Dunham, VE7CIO, Laurence Holloway, VE7ADC, Jerry Szakal, VE7COI, Ralph Webb, VE7BVG, Vic Medway, VE7CON, Pat Cavanagh, VE7CAV, Bob VE7CHB, Doug, VE7CBM, Peter Desrosier, VE7CGZ and his wife Lise.

S.A.R.C

1976 - 1977

President ------- Fred Orsetti, VE7CJG
Vice Pres. -------- Bob Searle, VE7CHB
Sec. Treas. ---- Carl Bertholm, VE7CLC

We acquired a portable tower and TA 33 Jr. beam for use on Field Day. We moved to Monkey Mountain, just east of Abbotsford on the suggestion of Al Neufeld, VE7CDC. The site will always be remembered for its wonderful view and the terrible access road. Bob, VE7CHB, and Peter, VE7CGZ kept the crew furnished with nourishment throughout the weekend.

The club was licensed as VE7SAR under the sponsorship of Cary, VE7CFC, holder of an advance amateur certificate.

Our first annual Christmas Party was held at the Islanders on the King George Highway near White Rock.

This was also the year of the Canadian Pacific Airlines (CPA) tour conducted by Tony Craig, VE7XQ.

1977 - 1978

President ------- Mike Holley, VE7AVM
Vice Pres ----- Carl Bertholm, VE7CLC
Sec. Treas ---- Mike Heritage, VE7CLE

The Ten Meter net was initiated with Fred, VE7CJG and later operated mainly by Carl, VE7CLC and Mike, VE7CLE. In the early days, we did have code practice by Mike, VE7AVM after the net. The net is held every Sunday on 28.675 MHz at 0400 Zulu.

The second annual Christmas party was held at the Surrey Inn where we competed with the QRM of the Saturday night disco.

Field Day was a great success. The club station was again located high on Monkey Mountain. It was announced in QST that we were top Canadian in category 3A. the "other" club made a late submission and we dropped to second place. Not bad for such a young club.

We had our first auction at North Surrey Senior Secondary School. It proved to be quite interesting and lots of fun on the sidelines.

1978 - 1979

President ------- Carl Bertholm, VE7CLC
Vice Pres. ------ Mike Heritage, VE7CLE
Secretary -------- Joan Gendron, VE7CTB
Treasurer --------- Jim Johnson, VE7CSJ

This was a very active year starting with an over subscription of new students. Max Green, VE7DZ took over the duties of teaching theory.

Prior to the start of regular meetings, the club held a picnic for members and families at Port Kells Park on August 27th.

The club held its first Flea Market at the Hjorth Road Hall, Sunday October 15, 1978. It was considered a great success as we had buyers and sellers from all over the lower mainland.

The annual Christmas party was held at St. Helen's Church hall with Woodwards doing the catering.

Fred, VE7CJG took charge o the bunny hunt with a borrowed bunny from BCFMA. It was not too popular a project and this was attributed to the fact that for some unexplained reason Cary, VE7CFC kept winning.

A successful pre Field Day trial was held at Surrey Place with the aid of the Gendrons' motorhome. There was a Teletype display in the mall with Cary, VE7CFC sending pictures from his QTH in Delta.

The club purchased a generator and a 204BA monobander for use on Field Day. Field Day was held again on the excellent site on top of old Monkey mt. Carl, VE7CLC and Mike, VE7CLE were responsible for the well being (food wise) of all those who participated. And we did come first in Canada and I believe eleventh overall in the 3A category. This was a perfect ending to a great year of Hamming.

The club Bulletin was conceived by Bob Searle, VE7CHB, nurtured by Doug Moore, VE7CBM and finally adopted by Carl Bertholm, VE7CLC. It has proved a very valuable asset to the club.

Our big venture was the Club Certificate commemorating Surrey's 100th birthday. This was a great success thanks to the hard work of Cecil Boggis, VE7YM in making so many contacts and Doug, VE7CBM taking care of all the paper work. Certificates were sent to England, France, and South America, Australia and practically every state in the United States. The project was made possible by a grant from the Surrey Centennial Committee and the assistance of Fred, VE7CJG and Carl, VE7CLC in the printing.

1979 - 1980

President ------- Bill Driscoll, VE7ARL
Vice Pres. --------- Al Neufeld, VE7CDC
Secretary --------- Mike Foster, VE7ACZ
Treasurer --------- Lee Hopwood, VE7BDZ

Another great year for the club. Fred, VE7CJG built a bunny and conducted several hunts. They just never caught on as we had anticipated. Maybe a new twist is required.

Two Flea Markets were held at Hjorth Hall one in October and the other in March. They appear to be very popular with Hams.

The club took part in the PNE Amateur Radio booth. The portable tower and beam were put to good use.

The annual Christmas party (dinner & dance) was again held at St. Helen's Church hall. It was well attended.

The club set up a working station, VE7SAR in Bear Creek Park as part of the celebrations for Heritage day. The Gendrons, Joan & Len, again graciously made their motor home available. The club also provided communications for the Delta Family Days.

Due to more than unusual road conditions up Monkey Mountain, Field Day was staged on the property of Joe Chesney in Langley. Our generator refused to cooperate so Ralph, VE7PWA, supplied ni-cad batteries. Fred's generator kept everything charged up. The new 4-element 15-meter monobander made Fred, VE7CJG and Jim, VE7CSJ was given a good tryout. Mike, VE7CLE was responsible for procuring all the materials for the beam.

1980 - 1981

President ------- Fred Orsetti, VE7CJG
Vice Pres -------- Cary Miller, VE7CFC
Secretary ------ Chris Johnson, VE7FFJ
Treasurer -------- Lee Hopwood, VE7BDZ

The club switched from the Electronics room to ordinary classrooms at North Surrey Secondary. But due to the strike by CUPE members, we were obliged to meet part of the time in the Main Library in the Guildford area.

Max, VE7DZ is still successfully preparing students for the amateur examinations.

This was the term when we finally got contact with EMO through the persistent efforts of President Fred.

No bunny hunts were held but there were two Flea Markets in operation again.

The Christmas Party was held at the Scandia House in Walley. The restaurant has since blown its finals and is no longer in operation. Olaf Saetre, VE7CIS, arranged the party.

The Field Day site was back on Monkey Mountain, Carl, VE7CLC and Mike VE7CLE again took care of the mess tent. An added feature was the presence of the Scout troop from Cloverdale for the purpose of helping to set up and take down the tents and equipment. They also provided Mrs. Murphy's parlour. The total points accumulated were not the great but all who participated had a super time.

'Get On The Air'

'Improve Your Signal' Presentation

Our first SARC General Meeting of 2020 was Wednesday, January 8th. 

One of our best attended presentations ever

As a result of feedback from our Basic courses, we planned a presentation and panel discussion around the basics of getting started in Amateur Radio. This was intended not only for new Hams but also those looking to improve their station capabilities.

We covered primarily VHF/UHF gear, antennas, power and accessories. Based on the interest in this session we will host a similar topic focusing of HF later in our meeting schedule.

We asked our SARC members to bring along any good used gear for sale and a few items showed up.

By request, here is the slide deck from the presentation:

Back To Basics: Overmodulation

Overmodulation Leads To Interference!

Question B-001-019-003 (A) - From the Canadian Basic Question Bank:

An amateur station using radiotelephony must install a device for indicating or preventing:

a. overmodulation 
b. resonance 
c. antenna power
d. plate voltage

The  key word here is must. All four of the above can be measured in a transmitting station but not all are required to be indicated or prevented. Only one is harmful to the extent that it can seriously affect enjoyment of the airwaves and cause interference to other Amateurs.

Overmodulation is the condition that prevails in telecommunication when the level of the modulating signal [the intelligible portion holding information— such as spoken audio from a mic] exceeds the value necessary to produce 100% modulation of the carrier. A carrier signal is one with a steady waveform, constant height (amplitude) and frequency shown in the diagram as the envelope. Modulation is superimposed on the carrier at the transmitter and recovered at the receiver.

In layman's terms, the signal is going "off the scale". Overmodulation results in spurious emissions by the modulated carrier, and distortion of the recovered modulating signal. This means that the envelope of the output waveform is distorted. The usual way of ensuring you are not over-modulating is to use the ALC on your HF radio, which will tell you if the audio level is too high.  It is also good practice to monitor your own audio while transmitting to ensure you are not too close to the mic or speaking too loudly, as the presence of distortion will be a sure sign that your audio is driving the transmitter too hard.

In the diagrams above, A indicates an Amplitude Modulated (AM) signal that is modulated to a low percentage. When modulation is increased to 100%, as in B, we are on the threshold of overmodulation. When increased above 100% as in C, the signal is said to be overmodulated resulting in distortion and spurious emissions.

See a demonstration here on YouTube.

There are several questions on overmodulation in the question bank and one is always on the Basic exam.

Resonance is a desirable state when tuning to a specific frequency but does not have to be measured.  Antenna power and plate voltage may be measured but that is also not mandatory.

The correct answer to this question therefore is ‘A’ Overmodulation.

New Year's Resolutions: 2020 Edition

Happy New Year!

The New Year has arrived and Hams, like so many others, may have a few resolutions to consider. I think we all recognize that the hobby is going through change. While the number of licensed Amateurs in North America continues to increase, likely due in large part to the ease with which a license exam can be passed, the number of ‘active’ hams seems to be diminishing. One only has to monitor a repeater or tune in to a weekly net to realize that participation has dwindled. With this in mind, I offer a list of amateur radio new year’s resolutions and encourage you to try to adopt some or all with your own goals for 2020.

On the west coast we hear about the impending ‘300-year’ earthquake frequently and have regular drills to prepare, including checking into an emergency net. That earthquake could happen tomorrow or at some point past our lifetime—despite some believable scientific data, no one knows for sure. But there are more common calamities that could happen sooner, and have over the past few years. A major snow or wind storm… an extended power outage.

"Five minutes before the party is not the time to learn to dance"

It is a good idea to make preparations now without the stress of a fast approaching deadline. If you are thinking of replacing or building an  antenna for use in an emergency, now is the time to build it and test it out at a leisurely pace. We have in the past, and will continue to present, home built antenna projects in SARC publications. If you’re not that handy, ask about the antenna workshop we offer to all our Basic course students. We also have a cadre of willing ‘Elmers’ who will help you with advice and assistance to set up that antenna.

Another aspect of Amateur Radio that comes into focus now is contest season. There is a contest every weekend in January, just check the calendar on: https://www.contestcalendar.com/. 

SARC has a contest group with tutors, and we invite your participation. Even if you only have a passing interest in contesting, come and try it at least once. Emergency focused radio operators will find contesting has many of the same challenges, and you will improve your skills, thereby becoming a better communicator.

Have a go at operating away from your usual location. It has been dubbed “Ham Radio Alfresco." There are so many hills, parks and beaches in our area that if you can’t find a place to throw a little wire in a tree and operate with low power off a battery, you aren’t looking hard enough. Your “portable” station can be anything from a  handheld or QRP single band rig to one of the big three’s latest 100 watt wonder radios that do everything from DC to Daylight. Just turn the power down so the battery lasts more than 10 minutes and you too can add another few ‘Qs’ to your logbook.

If you are thinking about trying to upgrade your license, now is the time to start studying. If your storage shed has a ton of old radio stuff in it, get busy and drag it all out into the sunlight and sort it out or throw it out. If you find you have a working radio or accessory that you do not need any more, consider donating it to your local Amateur Radio group. 
Come to a monthly meeting. You will find interesting presentations, lots of information and friendly fellow SARC members.

And lastly, please make an effort to use our repeaters once in a while. It would be very encouraging to hear some conversation outside of net night but, speaking of our net, please check in there too, we meet every Tuesday at 8pm 147.360 MHz (+600 KHz) Tone=110.9, or via Echolink.

73, and Happy New Year!

The SARC CW Course

Morse Code Is Not Dead!

CW – the Original (and arguably, the best) Digital Mode

Invented in 1837, CW which is more commonly known as “Morse Code”, was the very first mode of communication sent over a wire or airwaves.  It is called CW or “continuous wave” because it is an unmodulated radio wave of constant amplitude, though it might more accurately be called “discontinuous wave” since the wave is broken into short and long segments separated by spaces, to represent letters of the alphabet, numbers and punctuation marks.  It is legitimately a digital mode because it exists in only 2 states  –“on” or “off”.

The length of the dot (or “dit” as we prefer to say) and dash (or dah)  and the spacing between them is not arbitrary but has a fixed relationship.  If the relationship is not accurate, the quality of the CW will be recognized as “poor” and in extreme cases may be virtually unreadable.  While most CW heard nowadays is created by software and is therefore perfect, we occasionally hear on the radio less-than-perfect Morse Code, sent by operators still using a mechanical device such as hand key or bug.

Since CW has largely been abandoned by the commercial, military and transportation world, it is now virtually within the sole domain of amateur radio operators, whose passionate adherents will likely stand by it to the bitter end.  So, if you think CW is dying out, then listen on the 20 m band during one of the many CW contests throughout the year.  You will be amazed at the number of CW operators sending Morse Code at rates between a lazy 15 wpm and the a breakneck 50 wpm or more, from every corner of the world.  

If you wish to use radio to communicate by the most reliable and sensitive means, you will not use CW at all, but instead one of the modern “weak signal” digital modes such as FT8, JT65 and a whole slew of others,  which have transformed our ability to accurately copy signals which may be so weak that you cannot actually hear them.  This is a boon to communication as it allows information to be exchanged even when using low power transmitters and poor antennas – unavoidable for condo dwellers.  So these forms of digital certainly have their benefits.  

However, if you wish to enjoy amateur radio in the most traditional, challenging and enjoyable way, you will find CW is the method of choice.   Yes, you can deploy digital decoders to help you read CW on a computer monitor, and many do.  However, even the best digital decoders are inferior to your ears and brain working together.  So if you are serious about using CW, you really must learn to copy it by ear.  

As a beginner, you will likely start with a hand key to send the characters which require a separate wrist movement for each dit and each dah.   In the past, CW operators would typically graduate to a semi-automatic key called a “bug” which sends a series of dits when the paddle is pushed one way, but single dahs when pushed the other way.  That certainly takes some of the work out of sending.  Actually very few CW operators now use a bug although the holdouts can still be heard on the airwaves.  

CW sent by a hand key or bug is usually distinctive of the operator and can often be recognized in the same way that a person’s individual handwriting differs from that of others.   During WW 2 the identity of German and British radio operators could often be recognized by their “fist” i.e. individual way of sending code characters.   

Hand key

  

Semi-mechanical Vibroplex “bug”

Nowadays, 95% of CW operators use a paddle and electronic keyer to send CW.  This combination is a big step up from the hand key and bug because it allows sending virtually perfect CW, which means the dits and dahs are of the correct length and spacing.  The keyer can be a separate unit into which you plug your paddle or, more commonly, it is built into the transceiver.  You push the paddle one way and it makes a string of dits; push it the opposite way and it makes a string of dahs.   It is not difficult to master and the result is uniform and perfectly formed CW.

Kent paddle

Bencher paddle

Electronic keyer with built-in paddle

External Electronic keyer which requires a separate paddle

You may occasionally hear about “iambic keying” which allows the keyer to minimize the keystrokes or hand movements even further.  To visualize how it works, consider the letter “C” which can be sent iambically by merely squeezing the two paddles together. With a single-paddle or non-iambic keyer, the hand motion would require alternating four times for C (dah-dit-dah-dit).  Most CW operators have not mastered this technique and it is not recommended for beginners.

If you’re stuck in a rut and looking for a new and challenging experience, consider learning CW.  Persistence and practice will get you through in the end and you will be ready to join the select group of hams known as “CWers”.  I heartily recommend it.

We Wish You Joy!

And perhaps a Ham toy in your stocking

We here at

Surrey Amateur Radio Communications

wish you a joyous holiday season and

a very happy and prosperous New Year!

An old favourite:

'Twas the night before Christmas,  

And all through two-meters,  

Not a signal was keying up  

Any repeaters.

The antennas reached up  

From the tower, quite high,  

To catch the weak signals  

That bounced from the sky.

The children, with Basic,  

Took their HT's to bed,  

And dreamed of the day  

They'd be on HF, instead

.

Mom put on her headphones,  

I plugged in the key,  

And we tuned 40 meters  

For that rare ZK3.

When the meter was pegged  

By a signal with power.  

It smoked a small diode,  

And, I swear, shook the tower.

Mom yanked off her phones,  

And with all she could muster  

Logged a spot of the signal  

On the DX PacketCluster,

While I ran to the window  

And peered up at the sky,  

To see what could generate  

RF that high.

It was way in the distance,  

But the moon made it gleam -  

A flying sleigh,  

With an eight element beam,

And a little old driver  

Who looked slightly mean,  

So I though for a moment  

That it might be Wayne Green.

But no, it was Santa,  

The Santa of Hams,  

On a mission this Christmas  

To clean up the bands.

He circled the tower,  

Then stopped in his track,  

And he slid down the coax  

Right into the shack.

While Mom and I hid  

Behind stacks of CQ, 

This Santa of hamming  

Knew just what to do.

He cleared off the shack desk  

Of paper and parts,  

And filled out my late  

QSLs, for a start.

He ran copper braid,  

Took a steel rod and pounded  

It into the earth  

Till the station was grounded.

He tightened loose fittings,  

Re-soldered connections,  

Cranked down modulation,  

Installed lightning protection.

He neutralized tubes  

In my linear amp...  

(Never worked right before –  

Now it works like a champ).

A new low-pass filter  

Cleaned up the TV.  

He corrected the settings  

In my TNC.

He repaired the computer  

That wouldn't compute,  

And he backed up the hard drive  

And got it to boot.

Then, he reached really deep  

In the bag that he brought,  

And he pulled out a big box.  

"A new rig?" I thought!

"A new Kenwood? An Icom?  

A Yaesu, for me?

An Elecraft, TEN-TEC

Or Flex, could it be!"  

(If he thought I'd been bad  

It might be QRP!)

Yes! The Ultimate station!  

I suddenly got nervous?  

Could it be all those weekends

I worked Public Service?

He hooked it all up  

And in record time, quickly  

Worked 100 countries,  

All down on 160.

I should have been happy.  

It was my call he sent.  

But the cards and the postage

Will cost a month's rent!

He made final adjustments,  

And left a card by the key: 

"To Gary, from Santa Claus. 

Seventy-Three."

Then he grabbed his HT, 

Looked me straight in the eye, 

Punched a code on the pad, 

And was gone - no good bye.

I ran back to the station, 

And the pile up was big. 

But a card from St. Nick  

Would be worth my new rig.

Oh, too late, for his final

Came over the air.  

It was copied all over. 

It was heard everywhere.

The Ham's Santa exclaimed

What an old ham expects: 

"Merry Christmas to all, 

And to all, good DX."
