Free DV & the SM1000 – WebCast now live!

The Amateur Radio Experimenters Group this month has produced a video of the presentation given by David Rowe VK5DGR on his new FreeDV digital voice codec and SM1000 stand alone encoder/decoder unit. The talk is well worth taking a look at if you have any interest in how digital voice modes can be delivered over HF radio.

David talks about his pioneering work and the open source ideals behind it as well as showing the newly released SM1000 Embedded FreeDV encoder/decoder unit that can be used to add digital voice using Codec2 to almost any current amateur tranceiver.

It’s our intention to film more of the club presentations in the future so stay tuned!

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.

You can see here how far our signals reached.

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.

VI5ANZAC Thursday 30th April Results

The last evening of operating VI5ANZAC by members of AREG has now come and gone. This operation was headed up by Theo VK5MTM and covered a wide range of bands as well as some digital modes including PSK63, CW and RTTY. Here is Theo’s description of the evening (relayed from his Facebook accoiunt).

Last night I had the pleasure of operating the special event callsign VI5ANZAC from my house.

Being a special event callsign brings much demand for amateur radio operators (hams) all over the world to “work” or make contact with the special event station.

All up I made 134 contacts across Australia, New Zealand, Japan, Italy, Russia, Spain, Wales, Ukraine, England, Germany, Lithuania, Belgium, France, Netherlands, USA, Ireland, Isle of Man, Slovenia, Azores and Switzerland.

VI5ANZAC has been “activated” by different hams everyday this week via roster and I am extremely grateful to have had this opportunity.

Attached is a snippet of audio one of my “pile-ups” of several European stations all calling me at the same time to make contact with me.

My station is quite modest with only 100 watts of transmitter power and a basic antenna made from speaker wire strung across my backyard so I am extremely happy with my results.

The following is some of the statistics from Theo’s activation:

SSB FM PSK63 RTTY CW
10M 11
20M 69 3
40M 43 2 5
2M 1
