The talk this evening will be a show and tell of all of the events leading up to and during the RPM200 from the communications network’s perspective. There is much that happens behind the scenes to make this event possible. We will talk about much of that as well as showing what the club has now assembled in terms of supporting equipment. The results from things like the APRS experiment will also be presented, and some early thoughts on what we might do in that space next year will be given.

There will also be an opportunity for those who participated to give the committee their feedback on what went right, and what can be improved for next year’s event. Your feedback is invaluable to us as part of our drive to continually improve the event so please come along and share your experiences too!

In addition, there will also be a short business meeting, as well as the usual coffee, cake and chat afterwards.

Free DV & the SM1000 – WebCast now live!

Posted on by

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!

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.

David Rowe’s Background

David Rowe is a part time open source software and hardware developer and full time Dad.  He has worked on projects in VOIP, developing world communications, echo cancellation, speech compression, and digital voice over HF radio.

Prior to becoming an open source developer David worked as an engineering manager and has 25 years experience in the development of DSP-based telephony and sat-com hardware/software.   Somewhere along the way he picked up a wide mix of skills including software, hardware, project and business management, and a PhD in DSP theory.

David’s other interests include his popular blog (http://rowetel.com), bike riding, electric vehicles, energy efficiency, amateur radio (since 1981), and swanning around Adelaide drinking lattes.
