Horus 37: Flight Currently GO for tomorrow morning!

Preparations are continuing to fly a large helium balloon this coming Sunday from Mt Barker in South Australia. AREG will be flying the balloon on behalf of LaunchBox who are undertaking a schools science education program.

Lift-off is planned for 10am, with a flight path that currently looks like it will orbit the eastern Adelaide hills.

The only risk to the launch currently is the low level weather forecast. The Adelaide Hills area has received yet another significant rain band this evening. If this hasnt cleared by morning the flight start could be delayed. Watch this website for the latest news.

Predicted flight path, as per 2016-09-17 06Z GFS model. (5m/s ascent rate, 3.5m/s descent rate, 34km burst altitude)

Amateur Radio operators across SA and western Victoria as far east as Melbourne should be able to hear the telemetry transmissions on 434.650 MHz using 100 baud RTTY (7N2). If you decode the transmissions using the dl-flDigi program, you can contribute your received frames to the global pool of tracking data enabling us to follow the flight.

You can find a guide to tracking the balloon flight using the dl-fldigi software at the following link: https://ukhas.org.uk/guides:tracking_guide

As usual, the payloads can be tracked live on the Habhub Tracker, available here.

As an added bonus, this flight will be carrying an experimental payload transmitting 115kbaud FSK on 441.200MHz, downlinking live images from the payload. This payload has been in development by David Rowe (VK5DGR) and Mark Jessop (VK5QI) for some time, and utilises an open source modem stack. If all works as expected, images should appear on this page: http://ssdv.habhub.org/VK5QI

Project Horus Balloon Launch – Advanced Notice!

AREG members will again be involved DSC_6524with Project Horus, undertaking another high altitude balloon flight for some high school students on Sunday September 18th.

The Launch time will be 10.00am from Mt Barker, in the Adelaide Hills.

Amateur Radio operators from across SE Australia can get involved in the flight by contributing to the telemetry gathering effort. Tune your 70cm SSB radios to 434.650 and decode the RTTY telemetry using the dl-fldigi software.

Keep watching the AREG website for further details and confirmation of the flight day (flights can be cancelled up to 24hrs before liftoff if adverse weather is predicted).

AREG RD Contest 2016: Member Activity Report

RD Contest Trophy

RD Contest Trophy

The Remembrance Day Contest for 2016 has come and gone. AREG was well represented this year with a number of home stations as well as three portable efforts making their presence felt across the bands.

Three members, VK5AKH, VK5MTM and VK5GR banded together to form a three station team this year. Named “AREG: Mostly Harmless!”, it gave the club an avenue to participate in the contest whilst also allowing individuals to also work for an individual score. It will be very interesting to see how they placed!

A further three members, VK5WTF, VK5QI and VK5KX also gave it a go! The following are the stories from those who took part:


Andrew VK5AKH – Portable Sedan

Andrew headed out to a remote site and set up a formidable station. He finished up with 286 contacts and 294points. it was a fair effort to built this station as a single op on Saturday morning and as hard as he was pushing he missed the start of the contest. The 3.5+ hours of assembly had its toll later in the evening when he was a little tired. Next time antennas will be set up on the Friday leaving me fresh for an evening. A good time was had…

Grant VK5GR – Portable Tickera (Spencer Gulf)

Grant set off Friday night from Adelaide and arrived in Tickera, on the eastern shore of Spencer Gulf around 8.00pm. Station setup began bright and early Saturday morning. By 9.30am the basic station was running, so the extra time was put to use adding 160m dipole elements to the 80/40/20m mix. This was the multi-band resonant dipole’s first outing and it proved to be a very good field performer. After the contest it even allowed a quick PSK31 contact to Reunion Island on 20m no less!

During the contest, Grant made a point of operating for as many hours as possible, stopping only for ~1.5hrs around 5am for a quick nap. The effort paid off with 469 contacts and a total of 664 points (thanks to the graveyard shift multipliers). 160m paid off handsomely as well, with 41 contacts and almost a worked all VK Call areas in 8 hours (except for VK1 who didnt appear on the band). This was the first time Grant had operated on 160m and with luck now wont be the last!

Grant also experimented with RTTY this contest. While there were very few RTTY stations around, those he did work certainly helped his score, including his first 160m digital contact into VK4!

Theo VK5MTM – Home Station

Theo managed a Personal Best of 286 QSO’s/300 points. Operating from home, he had to battle solid S9 noise on 40m during the daytime and plasma TV noise 80% of the time on 20m (neighbour’s TV). Even so, a very respectable score was achieved!

Marcus VK5WTF – Portable Red Banks Conservation Park (near Burra)

Marcus (ex VK3TST) also headed out portable, but took a different slant on things. His intention was to go QRP phone from the get go, but to build a bigger than usual station. He also made the decision not to stay up, and admits that probably hurt his score, a lot, 83 points were gained in the hour before 6am.

Marcus’ Score was:

[table “” not found /]

His radios included a Yaesu FT-817 (not the ND) and a Yaesu FT-857D.

Antennas: 80/40 fan dipole, 20/15 vertical, 20m sloping yagi (supposedly pointing west), 160m EFHW. As far as antennas went, the poor attempt at a sloping wire yagi was full of fail. It must have been so close to the ground that it turned into an inverted-V. Marcus is thinking of making a 20/15 moxon for next time.

He also indicated that the highlight of his contest was a 160m contact with VK2IO, both portable in parks running QRP! A distance of roughly 1100km.

The ability to run a second radio was thanks to VK5QI who loaned him a 100A AGM battery. The rest of the station (817 & laptop) coped with 2x 12Ah SLAs a few Li-Ion pack to top up the batteries and 10+18W solar system. The 857 was the only thing hooked up to the AGM battery.


Mark VK5QI – Home Station

Mark decided to try out his new antennas and amplifier to see how he went. His tally was

[table “” not found /]

Mark commented that he was surprised:

  • That I could actually work people on 160/80m. The long-wire does actually seem to work! (Now to find a SG-235…)
  • The beam wasn’t that useful on 20m. I kept having to swing it around between VK6 and VK1/2/3/4, which got a bit annoying.
  • 400W certainly makes it easy to be heard – If I could hear someone, I could work them!

Peter VK5KX – Home Station

Peter admits his was a token effort – but he had fun (which is the main thing!)

[table “” not found /]

Overall, AREG was very well represented on the bands, and most of all everyone had fun!

See you next year on the Remembrance Day Contest!

High Altitude Balloon Launch WEDNESDAY 27th July with Willunga High School

Andy VK5AKH and Mark VK5QI preping the balloon

Willunga High School undertook a high altitude (well, not so high this time…) balloon launch Wednesday the 27th July, with some tracking support provided by AREG’s Project Horus flight team.

Willunga Balloon Prediction July 2016

WHS Balloon Flightpath Prediction

This flight was organised mostly (gas + balloon + payload + CASA) by a science teacher from the high school, with assistance from myself (telemetry + recovery). The launch being mid-week certainly doesn’t make it easy from our side, so at the moment the tracking crew consists of myself, Gary, and the Adelaide division of IBM Ozlabs (Joel Stanley and Andrew Jeffery).

The flight carryed a GoPro plus the usual tracking & cutdown payloads, beneath a 300g balloon. We expected a burst altitude of around 20km, with a predicted landing zone to the east of Swan Reach:

This was a fairly long distance flight for the predicted altitude, but the predicted flight path holds the promise of some pretty good video of the Adelaide area (assuming the ‘partly cloudy’ prediction happens). The VK5QI chase crew was on the road to Swan Reach roughly 30-45 min prior to the launch time, to get in position to both cutdown (if required) and recover.

Update: The Flight was a Success!

The flight has been a success and the payload was recovered (albeit a little further away than planned, about 10-15km south of Waikerie). Here was the actual track route from the chase:

IARU HF Championship Contest – THIS WEEKEND

The IARU Contest will be conducted this weekend on HF (non-WARC) bands from 10pm EST Saturday 9 July to 10pm EST Sunday 10 July 2016.

This is a good opportunity to test out the bands (particularly the lower ones) and get more more DX into your log.  The contest details can be found at http://www.arrl.org/iaru-hf-championship

The exchange is 59 and your ITU zone (e.g. VK6=58, VK8 and VK4 = 55 and VK2, VK3, VK5 and VK7 are in zone 59

The Wireless Institute of Australia will run a HQ station using the callsign VK5WIA.

The SSB station (80-10M) will be operated by members of the Amateur Radio Experimenters Group using Chris VK5CP’s station near Mannum South Australia.  We also expect to have a separate CW station coordinated by Chris VK3QB.
