OARC Club Project

We had a massive turn-out for the first session of this year's Club Project. Dave Conn/VE3KL is leading the group that is designing antennas using 4nec2 antenna simulator software as a design aid. They are building and then testing a 10m dipole. Group members are also building and testing 50 Ohm 1:1 Baluns and 50 Ohm Line Isolators. The first session was a great deal of fun. In the next blog entry you can find some photos.

Our sincere thanks to Algonquin College for allowing us to use their lab.

OARC RAC Winter Contest Claimed Score

Dave Green, OARC RAC Winter Contest Team Captain, compiled our results, here is his summary:

Total QSOs: 756

Total points: 3528

Total multipliers: 58

Final Score: 204,624

Compared to last year, there were some obvious differences:

While the CW QSO count held steady, the SSB count dropped by 174,

Total multipliers dropped from 79 to 58, final score dropped from 368,772 to 204,624, 80 m CW QSO count jumped this year from 71 to 129, 20 m SSB crashed, down from 200 to 84 QSOs. 15 m was a disaster, CW dropping from 43 to 8, and SSB dropping from 75 to 3 QSOs, 10 m was also dead, CW dropping from 30 to 0 and SSB from 18 to 2 QSOs. Multipliers on 20, 15 and 10 m were down a total of 22.

As is evident, the sunspot cycle is taking its toll on the upper bands suggesting that next year we will have to focus more carefully on 80 through 20 m.

We had an excellent turn out of OARC Members this year, despite the snow. We also had two new participants who made a big dent in our performance: Jeremy VA3ZTF and Carl VE3CZN blasted out a ton of QSOs on 40 and 80 m phone.

A special thanks to Nick VE3OWV for putting us up at Canada's Cold War Museum's Amateur Radio Station again this year. Nick has been instrumental in helping organize the antennas and the operating conditions at VE3CWM.

Also thanks goes to Helen, the operational manager at the museum for her assistance in arranging our extended hours access.The OARC is indebted to the management and staff of the Diefenbunker Museum without whose assistance entry into the RAC Winter Contest from this incredible location would not be possible.

November 2016 Meeting Location

We were unable to get any rooms at Ottawa City Hall in November since they were all taken. So, the November 9th OARC meeting location will be held at Makerspace North.

This temporary change of venue was announced at the October meeting and minutes and will be repeated again on the Capital City Net and Groundwave.

The address of Makerspace North is 250 City Centre Avenue, Bay 216 (access via the 2nd level ramp on the West side of the building). In case you will be mailing yourself to the meeting or your GPS gizmo has some other search features, the postal code is K1R 6K7. The nearest major intersection is Preston and Albert near the new Canadian War Museum.

It's a short walk from the Transitway's Bayview station. The main parking facilities are located on the East side of the building facing City Centre Avenue. There is limited parking on the ramp going up to the top level.

Ontario NVIS Event

Members of the Peel ARC are organizing an NVIS event in South-Eastern Ontario to practice using NVIS techniques for short-to-medium-range HF communications.

This event is set to occur Sunday, October 16th from 1300H to 1600H Eastern. Planning and details for member participation in this event will be happening on VE2CRA Thursday, October 13th at 1900H.

Excerpt from

"We invite you to a southern Ontario regional NVIS communications event on October 16th from 1-4 PM EDT. The goal of the event is to make contacts and talk to other operators using NVIS techniques. No restrictions on operation, just get on the air and operate with your best NVIS antenna. Bands of interest are 40, 60, and 80, depending on conditions. Suggested frequencies for SSB are 3.700-750, 5.357, and 7.060-070. CW, 3.550, 5.3465, and 7.030. We suggest this identifier when calling to make it easier to identify the participants: CQ NVIS Ontario 'call sign'. Ham operators across the province in many different clubs have expressed interest and hope you will join us on the air."

Further details from Peter VE3POA:

"To date the following clubs have expressed interest in participating: Hamilton Peel Niagara Kitchener Kingston York Region" Other clubs have been reached out to and we are now waiting confirmation of participation. It would be great if there was some interest from the Ottawa area and are able to join us in on the fun.

"This is more about experimentation and playing radio vs the competitive contest. No restrictions on equipment or locations, just get on the air with what ever antenna one thinks will work well for NVIS communications. Individual, group, at home, or in the field stations are all encouraged. More the better and likely better chance of qso's. "

Field Day 2016

The last full weekend in June always coincides with Field Day. This year it falls on Saturday, June 25 and Sunday June 26. We are back at the Corkery Community Centre, 3447 Old Almonte Rd, Ottawa, Our old site at 175 Main St., is no longer available as it is under going major construction.

You can find a link to the site with a map here:

The OARC Field Day Committee is planning a fun filled opportunity to get on the air. All are welcome - old hands and rookies alike.

Field Day is an operating event sponsored by the ARRL whose purpose is to demonstrate the communications ability of the amateur radio community in simulated emergency situations. The aim is to work as many stations as possible on any and all amateur bands (excluding the 60, 30, 17, and 12- meter bands) and in doing so to learn to operate under less than optimal conditions.

Set-up will be from 10 am until 2 pm. We should be up and running by 2 pm and will be on the air for 24 straight hours. We operate as a 2 Alpha Ontario station using the OARC Club Call Sign - VE3RC. That means we operate 2 transmitters (plus a VHF/UHF station) independent of commercial power mains. One transmitter is devoted to CW (Morse Code) and the other to SSB (voice). We expect to have a GOTA (Get on the Air) station, where rookies and unlicensed potential amateurs are welcome to make a few contacts.

Help with set-up & tear down (after 2pm Sunday) is always appreciated.

The OARC Field Day is a very relaxed event. You can come and go as you please; you are not committed to anything. If an operating position is vacant, don’t hesitate to pick up the mike/key. It’s a good idea to bring a lawn chair, however, there never seem to be enough. You don’t need to bring any other gear.

You are welcome to stay for meals, but it doesn’t hurt to tell Janice (VA3PAX) that you’ll be there. Janice’s meals are almost legendary! We eat at:

1 pm Saturday

6 pm Saturday

Noon Sunday

If you are on site you are welcome to join us.

The main thing to remember is that the OARC Field Day is first and foremost a social event and the aim is to have fun and spend some time with your OARC friends. Any last minute information will be posted here on the club’s web site:

See you there
