20th November Meeting: VHF/UHF Contesting

Posted on by
VHF/UHF Spring Field Day - VK5ZM 2015

VHF/UHF Spring Field Day – VK5ZM 2015

Have you thought about trying any of the VHF/UHF field days?  Do you still have fond memories of being a “Z-call” when the lowest frequency you could operate on was 29MHz FM?

Well a few of our members thought it would be fun to head out and participate in the Spring VHF/UHF Field Day on the 14th and 15th of November.  For some of our members it had been more than 17 years since they had done one of these events.  This was also a welcome break from the usual HF contesting our members have been doing lately.

So this month we’ve asked these enthusiastic members to put together a short series of 10 minute presentations about what they did, how it went and was it still fun to be a “Z-Call” again.

So if you’d like to hear more about what it takes to participate in a VHF/UHF field day then come along and I’m sure there will be something there for everyone.  It should be a good night out and if the enthusiasm of our members who participated this year is any indication, this could be infectious.

The meeting club rooms will be open at 7:45pm with the presentations starting at 8pm.   This will also be the last formal presentation/meeting for the AREG in 2015.

As well as the formal presentation there will be ample time to meet with AREG members and talk about any and all things Amateur Radio. Visitors are most welcome, so please come along all and say hello! If you need help finding the hall, call on the VK5RSB 439.900 repeater (91.5Hz CTCSS).

Coffee, tea, cake and 2m LFA designs will be supplied as a light supper.

LaunchBox Horus Balloon Flight 18th October 2015

This weekend was the first Project Horus activity for this year, when we teamed up again with LaunchBox to put a School payload aloft. The students designed a number of experiments and flew them in a payload chassis supplied/organised by LaunchBox. Project Horus then provided tracking telemetry payloads and recovery teams and vehicles plus flight engineering services to the LaunchBox team to enable them to get the student payloads aloft.

The large turnout of students on a Sunday morning showed that there is still plenty of curiosity and interest in science in schools which is great to see! This was especially so considering the types of questions the AREG team was fielding, which bodes well for science education.

Launch Operations

Filling and launching went without a hitch, and the changes to the regulator and filling system that allowed the balloon to be filled in under 5 minutes was a welcome improvement! Thanks Dennis VK5FDEN for helping out with this.

The flight was planned so that recovery would be relatively painless, with the target area being somewhere in the vicinity of Palmer in the Adelaide Hills. This level of control is only possible because of the flight tele-command capability that the team has devised, and plays a big part in the success of these flights for groups like LaunchBox.

Tracking Network

Another major piece of the puzzle was the tracking network. The primary telemetry this flight was based on a 100 Baud 7N2 RTTY signal on 434.450, with a backup trial system using LoRa modulation as an experiment. This telemetry, apart from being received in the tracking chase cars, is also collected by a large number of Amateur Radio ground stations across South Australia. These stations make a major contribution to the project through collecting and feeding the balloon telemetry into the Internet. This is then accessed from our chase vehicles over 3G/4G cellular links and adds to our own data. It is a great way of getting involved, even if you are not out in the field.

Michael VK5ZEA and Peter VK5KX posted the following pictures of their setups and what they saw at various stages throughout the flight.

Others contributing to the tracking included numerous stations in Adelaide; VK5ALX and VK5NEX in Whyalla, and VK3BQ, VK3SMC and VK3KCX in Melbourne.

Flight Statistics

To control the landing zone, the flight itself was terminated early using the Horus tele-command system. (Had we waited in this case for the balloon to burst, it is quite possible it may have landed much closer to heavily populated areas, something we do our utmost to avoid). The final flight statistics are therefore as follows:

Recovery

Recovery went smoothly with both chase teams waiting patiently for landing approximately 1km from touch down. After locating the land-owners and obtaining permission to enter their farm, we were able to walk in about 600m and collect the payloads.

The main payload has several experiments including cameras, a weather station, and other interesting ideas contributed from students to answer questions like “what does happen to a marshmallow and popcorn when you place it in a freezing near vacuum?”

Conclusion

The day ended with the LaunchBox and AREG Project Horus chase teams meeting at the Palmer Hotel to hand over the payloads. A job well done everyone, and a great example of using Amateur Radio to further science education in this country!

Again we must say a big thank you also to the HabHub.org community and the UK High Altitude Society who provide balloon tracking and telemetry collection services for projects such as ours across the world.

Stay tuned in the new year as well as there are many more exciting things potentially happening with Project Horus being considered for 2016!

VK5ARG Oceania DX Contest 2015 Results

Posted on by

Well, the AREG has wound up it’s activities sidebannerat Para Wirra
Recreation Park for this year’s contest. A great deal of fun was had by everyone to participated, even by those who operated under physical duress (two members could hardly walk).

A big thanks to everyone who took part and operated or provided support for the event. In particular (and if we’ve missed you out please let us know and we’ll add you to this list) those who took part in operating the station included: VK5AKH, VK5ZM, VK5QI, VK5KX, VK5FSKS (who flew in from VK3), VK5GR, VK5JO, VK5MTM, VK5UP, and we believe that VK5FGRY was spotted sitting at a few consoles however we’re not sure if he transmitted or not this year (*grin*).

With the Para Wirra CP being so close to Adelaide we were also fortunate to have a large number of visitors which included; Kim VK5FJ, Arno VK5ZAR, Paul VK5JG and Dennis VK5FDEN, Cary VK5CD, Peter VK5APR, Louis VK5FLY and Jess, Wendy, Dean VK5FAIR and Sally VK5FSAM,  Brenton VK5BZ, Ben VK5BB, Darin VK5IX and Glenys plus boys, Sharon FSAW and the Moo, Allan VK5MAK, Bob VK5FO and Ray VK5RR.

We also must thank Arno VK5ZAR and Gary VK5FGRY who helped keep the troops fed manning the BBQ and keeping the ants at bay as well as Sharon VK5FSAW who provided dinner on Sunday night.   We must also thank all of the visitors that rang ahead and checked if we needed anything, with the weather so warm the bags of ice, drinks and loaves of additional bread were gratefully received.

A big thankyou again to the rangers of Para Wirra Recreation Park (Steve and Mel!) who graciously allowed us to conduct the event inside the park for the 3 days. To find a site so close to Adelaide with such a low HF noise floor is a wondrous thing.

The Results?

Overall our tentative scores were:

[table “” not found /]
[table “” not found /]

Band by Band

80/160m: With changes to the radios this year, it was fantastic to see the contacts and multipliers achieved out of the low band station. Peter VK5KX and the low band crew achieved contacts into ZL on 160m and into the USA on 80m. Well done!

This slideshow requires JavaScript.

40m: was hard going this year. We lacked enough punch to be heard often in Europe and that cost us many contacts in the early hours of the morning. We did get a few contacts into that part of the world but often it was through multiple repeats and perseverance. The auto keyers got a work over and between Josh VK5JO, Andy VK5AKH, Grant VK5GR, Matt VK5ZM and Mark VK5QI plus other relief operators, we ground out a solid score. The tube amp and dipole did well to the USA – but the fixed orientation wasn’t helping our cause for Europe. More work and ideas planned for this station next year :-)`

20m: at times flew and at others was a grind. Again, punch to get over the European QRM made prefix chasing hard work although a solid result was still achieved with the Elecraft K-line and the Hex Beam. With 40m and 20m being co-located teams were taking turns at each station making further contributions to both stations.

15/10m: The surprise this year was 15m. We again had a Elecraft K-line and a 3-band Spider beam which we ran for the John Moyle Field Day. With that setup and the ionosphere playing the game the crew manning 15m had a huge amount of success. Long runs of Japanese stations as well as a beautiful opening into Europe Saturday night brought a sparkle to Matt VK5ZM, Theo VK5MTM and high band crew’s eyes.

Conclusion

All in all, a great result, a lot of fun and look out for AREG again next year!    Meanwhile, ideas for improvements to the station are already circulating, and we wait with bated breath to see how we placed.

A big thank you to the OCDX contest organizing committee for staging the event too. It certainly gave our club the excuse to get out and play portable “Amateur Radio” for the long weekend.

Members of the AREG will be activating the Club Call sign VK5ARG for this event from the Para Wirra Recreation Park, north east of Adelaide. The OceaniaDX contest provides a great opportunity for Oceania stations to get on the air as there is lots of activity in our region. Whats more, the DX chasers from around the world will be actively looking for Oceania! Hopefully the propagation will favour VK5. More information on the OCDX contest can be found via the WIA website.

Contest Times: 08:00 UTC (17:30hrs ACST) Saturday 3 October to 08:00 UTC (18:30hrs ACST) Sunday 4 October 2015  (Yes Daylight savings starts this weekend too!)

AREG welcomes all amateurs with an Para Wirra Park Mapinterest in portable field stations and contesting to come on up to the park and visit us over the weekend. Entry to the park will cost $10 / vehicle for a one time fee for the weekend.

While the park closes at dusk, the radio club has sought and obtained special permission from the park rangers to remain in the park overnight. To find our operating location, enter the park from the main gate off Humbug Scrub Road, proceed past the the park office then past North Oval until you reach the toilet blocks, picnic shelters and open paddock at the end of the bitumen.OCDX-StationLocationMap-2015

More than just contesting!

Saturday Afternoon prior to the contest AREG will be having a HF activity afternoon with a mixture of SSB and FreeDV operation on both 20m and 40m. This will be another great opportunity to test FreeDV. The VK5ARG team will be monitoring the FreeDV QSO finder, and posting regular blog updates as the afternoon evolves. Activity is planed from 1500-1700 Local time but may start earlier depending on interest.

AREG General Business Meeting: August 21st + Guest Speakers !

Posted on by

The next meeting of the Amateur Radio Experimenters group will be held on Friday 21st August. The venue as always will be the Reedbeds Community Hall, 19 Fitch Rd, Fulham SA 5024.

This month there will be two guest speakers giving short presentations interrupted by a short business meeting.  Doors open 7:45pm, first talk starts at 8pm sharp !

Everything 6m!

The first speaker will be Ben VK5BB P1020591who will give a 10 minute  talk on the Amateur 6m band and what it has to offer in the summer time months.  With summertime on the horizon (finally) it’s a good time to dust off the low band VHF 6m gear and get it ready for the upcoming summer months !!!

This will be followed by a short general business meeting.

FreeDV – getting it working!

The second  short technical presentation will be by David VK5DGR on the practical aspects of  alignment, use and getting a FreeDV signal to air.  With the AREG FreeDV QSO Party (click) just around the corner, now is perhaps a good time to get that SM1000 or PC Interface at the ready !   As is typical with all of David’s talks it certainly should be a good time to sit back and watch or hear Digital HF Voice first hand.

This of course will bearegmap interspersed with coffee, cake and opportunities for technical chats around the kitchen bench.  Should be a good night to get out of the house and come and play radio.

Look forward to seeing you there
