FreeDV – What’s it about?

The SM1000, is an embedded hardware product that allows you to run FreeDV without a PC. Just plug it into your SSB or FM radio, and you now have Digital Voice (DV).

It’s based on a STM32F4 micro-controller, has a built in microphone, speaker amplifier, and transformer isolated interfaces to your radio. It’s just 80 x 100mm, and can be held in you hand and used like a regular PTT microphone, or sit near your radio in a small box form factor.

In this presentation David will discuss the SM1000, and how it was developed by 2 Hams and a Chinese entrepreneur over the last 14 months.

AREG assists AHARS with VK5RAD 70cm Repeater Restoration

repeater tower clipartIn the last week, AREG members have teamed up with the Adelaide Hills Amateur Radio Society (AHARS) to help bring the Crafers VK5RAD 70cm 439.925MHz repeater back to life. Temporary equipment has been loaned to the site while repairs continue on the original repeater.

VK5RAD 70cm Repeater Access Details:

  • Repeater Transmit: 439.925MHz
  • Repeater Receive: 434.925MHz (-5MHz offset)

Thanks to everyone at AHARS and AREG for restoring this valuable service to amateurs in the greater Adelaide area.

NOTE Regarding IRLP Node 6214

The 6214-IRLP node currently is still on  the VK5RSB 70cm repeater on 439.900 (contrary to what was broadcast on the WIA Sunday News this week). AREG is discussing the plans for its move currently with AHARS and the AREG membership. We will advise when the IRLP gateway does move.

The highlights of the activation for us were working a number of the Turkish special event stations! It was great to make these contacts.

Turkey Stations Worked 2We also made contact with many of the Australian VIxANZAC stations during the weekend.

Detailed information on the locations we worked is available from the following links:

AREG would like to thank the Wireless Institute of Australia for all of the efforts they have made to arrange for and coordinate the state based commemorative callsigns. This event remembering  the 100th anniversary of the ANZAC landing at Gallipoli in Turkey during World War One is certainly one of international significance. Through the global friendship of amateur radio and our communications with stations across the globe, we hope that by putting these stations on air that we have strengthened global peace through remembering the impact and abomination of war.

Attention all club members – the radio operator registrations are now open for this year’s event. Please access the registration form link e-mailed to all members via the mailing list and complete your details for 2015 as soon as possible so that checkpoint planning, accommodation and catering can all be finalized. Note: the AREG home base this year will be the Kingston on Murray Caravan Park.

AREG activation of VI5ANZAC 25th – 30th April 2015

The Amateur Radio Experimenters Group will be participating in the WIA organised special event callsign activation of VI5ANZAC. The major commemoration is on the 25th April 2015, which is when Australian and New Zealand troops landed at Gallipoli, marking 100 years since our nation’s involvement in WWI.

The club has secured the window from 0000UTC (9:30am CST) Friday 24th April through to 2359UTC 30th April (9:30am CST Friday 1st May) to activate the callsign. After interest was also expressed from the Elizabeth Amateur Radio club to operate portable from an RSL hall on ANZAC day, AREG has cooperated and agreed to EARC operating the callsign up until 12.00pm CST on April 25th, so that operators from both clubs can share in the experience.

The principle goal of AREG with the callsign is to contact Turkey on HF after 12:00pm CST (0230UTC) on the 25th of April (Anzac Day) as well as provide an easily reachable signal across VK/ZL (and all points in between). A large construction project is underway at one of the club members stations aimed at installing a 3 element 40m beam and 4 element 20m beam in time for the event. The AREG also intends for it’s members to activate it as often as possible from AREG members stations thereafter within the club’s operating window on HF and VHF/UHF as far as possible.

More details of AREG’s exact plans will be released closer to the event. At this stage, members are asked to contact the committee to place their details on the club roster for activating VI5ANZAC between Sunday 26th April and Friday 1st May 9:30am.

This is also the second anniversary of the VK5 Parks Activation Weekend  event organised by the Adelaide Hills Amateur Radio Society. Paul VK5PAS who has driven the VK5 Parks Award has done a sterling job and promoting HF and VHF/UHF portable operation through this initiative giving amateurs a great incentive to get out and about and see the natural wonders of our state while playing Amateur Radio.

Operators of VK5ARG this weekend will also be making contatcs under their own callsigns during the VK5 Parks Activation, so look out for Mark VK5QI/P and Andy VK5AKH/P (and others) on the bands. For more information about the VK5 Parks Award visit their website.

Antennas will be 16m tall vertical on 160-30m, inverted Vee on 40m and 2 element hex beam 20-10m. Operating Low Power as generators are not allowed in the park. Good luck in the contest and hope to see you in the log.

Website back up !

LcK75XpcaThe AREG website is back up after a short outage over the weekend.

In recent weeks there have been numerous security updates and advisories released for Apache Web Servers.  These had been backing up for a while and were batched process in one large go Friday afternoon.  Unfortunately one of the updates broke the website and it wasn’t picked up before the club meeting.

Our apologies for the website being down, there should be a flurry of activity as a result of the Club Meeting Friday night, stay tuned !
