AREG and the Spring VHF/UHF Field Day 14/15th November

Posted on by

VK5ZM Portable Array ready for the field day

Recently with the HF conditions deteriorating the operating interests of a number of club members has been switching to VHF/UHF. To help get their VHF/UHF stations “tuned up” for portable operation, a number of members are taking the opportunity to participate this year in the WIA Spring VHF/UHF Contest.

AREG members haven’t actively participated in this contest for a few years now so this marks a return to these bands for quite a few of us.

About the Contest  (Extract from the WIA Website)

The VHF-UHF Field Days provide VHF-UHF operators with the opportunity to “head for the hills” and see how far they can work.

The Field Days have separate sections for single and multiple operator stations. The duration of the Field Day is 24 hours, but there are also 8 hour sections for operators who may not be able to camp overnight. Most club stations prefer to operate for the full 24 hours.

The Field Days also generate plenty of activity from home stations, so there is also a separate Home Station section.

All contacts must be simplex: contacts through repeaters or satellites are not allowed. There is plenty of FM activity, but one feature of the Field Days is a high level of SSB activity.

It is possible to do very well with only modest antennas if you pick a good hilltop. Another option, if your station is easily transportable, is to operate from more than one location during the contest period.

Aim Of The Contest

The overriding aim is to get away for the weekend and have fun! But next after that, the aims are:

  •    to encourage more activity on VHF and microwave bands;
  •    to encourage people to work greater distances than usual by operating portable, and
  •    to provide opportunities for people to activate or work into new grid squares.

AREG Involvement

VK5QI, VK5FO and VK5ZM are all preparing stations. Most club members are planning on operating in the 8hr section for the first 8 hours of the contest. Several sites around the Adelaide Hills and metropolitan area are being considered for activations. VK5FO and VK5RR will be operating from Saturday 0100hrs UTC for 8 hours from Ardrossan with:

vk5fo-antennas

VK5FO antennas on test

  • 6M – 2 elements (horizontal) and 100W on the IC706. SSB and FM
  • 2M – 6 Elements (vertical) and 50W on the IC-7100. SSB/FM AND RTTY
  • 70Cm – 17 Elements (vertical) and 50w on the TS-2000. SSB and FM

Bob and Ray should be capable of working most home and portable stations in the Adelaide Metro area and will be running SSB and FM. They will also beam towards Port Pirie, and Pt Lincoln.

VK5QI Antenna

VK5QI Antennas

VK5QI is also organising a station with Andy VK5AKH and has some “rover” antennas prepared.

The idea of the contest has also inspired Matt VK5ZM to go on an antenna building spree with new 2m and 6m LFA beams built and ready plus a borrowed 70cm 9el antenna to give Matt 70cm capabilities as well.

VK5ZM 2m LFA Beam

VK5ZM and VK5FGRY will be headed to Anstey Hill, using a site suggested by Andy AKH.  You can find their location here; (VK5ZM Location for the VHF/UHF Field Day.)   Gary and Matt are just focusing on 6m, 2m & 70cm (FM/SSB) and Matt will take a 23cm HT (FM) if anyone wants to try, but it will be rubber duck.

They will be located within the Anstey Hill Rec Park with a good elevation (400m) and clear LOS to just about everywhere.  The site is a little shadowed to the southern suburbs and vales, but has a good outlook none the less.

Members are certainly welcome if they would like to come and visit VK5ZM and VK5FGRY. Note that parking is along the roadside so use your common sense here please.

It should be a great weekend so look out for these and many other stations participating in the WIA Spring VHF/UHF Field Day!

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:

[table “” not found /]

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!

NEWSFLASH: Project Horus Balloon Flight Sun 18th October

Posted on by

0a3QZ-425x640

On Sunday the 18th of October, at 10am Adelaide time, Project Horus will be conducting a high altitude balloon launch from the Mount Barker area. This launch will be flying payloads designed by Adelaide area high schools, along with the standard Project Horus telemetry payloads. The launch is expected to reach approximately 30km altitude, with telemetry receivable from most of VK3 and VK5. The launch site for this balloon will be closed to the general public due as school children are present, we thank you for your understanding.

Anyone wishing to help track the balloon is invited to listen out on 434.450MHz USB for the RTTY telemetry. This can be decoded with the standard dl-fldigi software.

  •  Main Telemetry: 100 baud 7N2 Telemetry on 434.450MHz USB +/- drift. Callsign will be VK5ARG-1.
  • We will also be flying a cut-down payload and an experimental ‘LoRa’ telemetry payload (431.650MHz).
  • An excellent dl-fldigi setup and tracking guide is available here: https://ukhas.org.uk/guides:tracking_guide

The Flight and Payload information for this launch will appear in dl-fldigi on Saturday the 17th. Tracking of the flight will be available on the HabHub Tracker page.

Current predictions, (as of Thursday the 15th), place the landing area somewhere between Pompoota and Bowhill:

Predicted landing area, as of the 15th of October.

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.

This slideshow requires JavaScript.

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.

Ocdx-logo-header

11080486_10152772912846188_3502356878582205362_oNext Weekend is the Oceania DX Contest, SSB section. 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.

FreeDV QSO Party – Activity Log for the 12/13th September 2015

Posted on by

5.00pm – Wrapping Up

Well, that about ends our FreeDV experiments for today. It has been great to see stations across VK and the world come and try this new mode. It was disappointing that the ionosphere ‘flamed out’ when it did but this is not going to be the last time we rally FreeDV users to come together and have a go, so if you missed out making a contact today, stay tuned for the next event.

We would like to thank all stations that took part or listened in and hope to see you all next time!

Regards, The team from the Amateur Radio Experimenters Group!

3:30pm – Now beaming LP Europe on 14236kHz

We are now attempting contact with Europe long path using FreeDV 700B. OE3GBB is reporting 70% copy and S4-5 – unfortunately we cant hear his responses as we have S9 noise here. Still, it is impressive that we are being heard!

Update: we did achieve contact with OE3GBB using a remote receiving station!

2:00pm – back from lunch and working some locals

40m is working into VK2 this afternoon on FreeDV 700B mode with contacts to VK2KDK and partial contacts to VK1KV. We will continue to have VK100ANZAC calling CQ beaming east this afternoon on 40m.

11:45am – all quiet – unfortunately

Well, our attempt here in Australia at getting the VK100ANZAC callsign out on freeDV is not going real well. The ionosphere coupled with local power line noise (which has sprung up today) have combined to make 40m and 20m very quiet (or should I say very noisy) indeed. We are still calling CQ with the keyer on 40m (7175) in 700B mode and are intermittently calling/listening on 20m (14236) in 1600 mode, but we are not working many stations.

We will press on in the hope conditions improve as the day progresses.

11:00am – worked VK3DBP on 40m

One station that has been actively working us is VK3DBP who has made several contacts including one around 11am ACST on 40m. Congrats for your enthusiasm for this new digital HF voice mode!

So, what’s this700B mode you are talking about?

On August 25th, David VK5DGR released a new version of the FreeDV software labelled version 1.0.0. This new low 700bps bitrate mode has better signal to noise characteristics than the original 1600bps mode but lower quality audio.

You can get the latest version and give 700B mode a try from these links:

10:10am – worked VK2DGH on 700B

Great signal now heard from VK2DGH on 700B mode. Also getting good SNR reports from VK1MTS (Rx Only) of 10dB SNR to VK100ANZAC – thanks for listening and joining in!

09:47am – contacts into VK4

VK4CAG has just had a great contact with VK100ANZAC on FreeDV 1600 – SNR 15dB – excellent signal into Mannum (SA) today and VK1MTS reported decoding VK4CAG on IRC.

Sunday 13th: 09:35am ACST – QSY 40m 7175kHz

80m NVIS into Adelaide was fading so we have moved to 40m in anticipation of the end of the WIA broadcasts around the nation. Look for VK100ANZAC calling CQ on that channel.

Sunday 13th: 09:00am ACST

Now also worked VK5APR on 80m. Also getting good reports from Michael VK5ZEA in Port Lincoln and Jeff VK5IU in Murray Bridge

Working VK5KDK on FreeDV 700B on 80m 3634.5kHz

VK5ZM FreeDV VK100ANZAC

Sunday 13th: 8:30am ACST – Experiments on 80m

This morning we are trying our luck with 80m. Currently VK100ANZAC is calling on 3.634.5 to give the local VK5 stations an opportunity. We have worked VK5IU on 700B mode and are continuing to call CQ.

Michael VK5ZEA has been hearing us in Port Lincoln.

We will be on 40m, a little later in the morning right after the Sunday morning WIA broadcast.

20m activity has been attempted USA longpath but no joy and nothing heard. The ionosphere is still not cooperating.

The operation continues…..

Sunday 13th: Look out for VK100ANZAC FreeDV on 80m as well

Following the relatively poor HF conditions we have set up one of the FreeDV VK100ANZAC stations to now also operate on 3635kHz. We will intermittently operate that frequency today (particularly early in the morning). If you want to attempt a contact with us on 80m chat with us on the FreeDV qso finder or on the FreeDV IRC Channel online!

Status Update: Saturday 12th September 9pm-12am ACST

The day has arrived and we are on the air with VK100ANZAC for the AREG FreeDV QSO Party. Unfortunately the ionosphere is not being very cooperative tonight with our first planned activation and so far no contacts have been made on 20m. Very little is being heard on the band at all, but we are there listening and calling none the less.

We also are listening to 40m around 7177kHz. Contacts were attempted with VK6 on 40m, and while faint signals were being heard, no decodes were achieved.

Discussion on the FreeDV QSO Finder shows that there is a lot of interest around however with a number of US stations attempting contacts between themselves. If nothing else, this increased activity meets the goal of getting people to come and try FreeDV!

1150pm – just tried a contact with K5WH on 700B mode – might have detected a few syllables but that’s about all. The ionosphere is not playing nice tonight…

Earlier in the day Saturday 12th

6 contacts were achieved earlier in the day on 40m with local Australian stations. Most of those were achieved using the newly released 700B mode. 5 stations succeeded in contacting VK100ANZAC using it. This lower bitrate mode has proved much more resilient in the poor HF conditions being seen this weekend. So, if you have an older version of FreeDV installed, then consider upgrading to the latest version and give the new 700B mode a try. (see www.freedv.org for details)

(Note: unfortunately 700B mode isn’t supported as yet by the SM1000 hardware adaptors so to use it you will need the latest PC software).

FreeDV QSO Party – QSL details for VK100ANZAC control station

Posted on by

The FreeDV International QSO party is coming up this weekend. Activity begins Saturday evening on the following schedule:

Bands and Times?

Various bands will be used, with thetiki-download_file2 primary call channels being 14236kHz +/-QRM and 7175kHz. The VK100ANZAC net control station will be listening and intermittently calling on FreeDV on the following bands:

  • Saturday evening September 12th from 1130UTC (9pm Australian Central Standard Time (ACST)) beaming short path North America on 20m (west coast).
  • Sunday morning September 13th from 2130-2330UTC (7am-9am ACST) on 20m beaming long path North America (east coast)
  • Sunday morning from 2230-0130UTC (8-11am ACST) will see local VK contacts targeted on 40m
  • 0430-0730 UTC (2-5pm ACST) will focus signals towards Europe Long Path as well as VK on 20m.
  • 0530-0830 UTC (3-6pm ACST) will see 40m targeting VK/ZL again
  • During the middle of the day on Sunday we may activate on 15m as well targeting Asia/Japan/Northern VK. Keep watching the AREG blog for details.

Many stations are already gearing up to take part and the operator team is getting ready to head to the station of Chris VK5CP for the weekend where the activity will originate from.

I’m a Foundation License holder – how can I get involved?

One of the very recent questions however was “How can Foundation Licensees take part in this event? While it is true Australian Foundation License holders can’t transmit FreeDV, they can still receive it. So why not have a go at installing the software on your PC, connect your radio’s audio output to your PC soundcard and have a listen around the bands for FreeDV signals!

You can provide feedback to the FreeDV operators during this weekend via Internet Relay Chat (IRC) on irc.freenode.net. (http://webchat.freenode.net/?channels=freedv) via the #freedv channel.

The FreeDV QSO Finder will also be used during the weekend. You can take a look and monitor the action here: http://qso.k7ve.org/  Note that the login system for this page uses the HamQTH Callsign Database, which doesn’t have many newer Australian Callsigns. If you get a “Callsign not found” error, you will need to register at: http://www.hamqth.com/register.php If you are listening only, you can log in as “SWL”.

You can also send us an SWL QSL Card via www.eQSL.cc! When a user sets the SWL/HAM checkbox in his Profile to SWL, it automatically forces all incoming and outgoing cards to say ‘Confirming SWL Reception’ instead of the usual ‘This Confirms Our 2-Way QSO’. If you are an SWL, just make sure to go to My Profile and set yourself up as an SWL. If you are a ham, when you send an eQSL to an SWL, it will automatically put the correct wording into the card.eqsl-header

VK100ANZAC QSL Cards for this event

All amateurs can also receive a QSL card for working the VK100ANZAC freeDV station. The WIA VK100ANZAC QSL card policy is as follows:

QSL cards are softcopy only via:
