Software Defined Radio

Software defined radios are the modern method of sythesising RF signals. Some SDRs give you the familiar frontend for radio operation while there are other SDRs that allow you customise the internal radio software. This special interest group seeks members who are wanting to experiment with their own SDR hardware. The SDR experimenters group will be a community of SDR enthusiasts wanting to help each other customise their SDR gear.

SDRs can be expensive transceivers right down to the receive only such as the RTLSDR.

The SDRSIG has it’s own website at¬†however as part of REAST we are syndicating the news feed here. If you would like to join the group, head over to the website and fill in the signup form which will add you to the mailing list. The website has a blog and events page, and members are encouraged to document their SDR experiments on the social network or on their own websites. The group mailing list where online discussions on SDR topics takes places as well as announcements of upcoming events.

The group is expected to be hands on, so if you are looking to join we encourage you to get hold of an RTLSDR receiver to start your own experiments in receiving and decoding signals. With some practical kit such as the RTLSDR, you can then learn by doing as we deep dive into topics of digital signal processing and synthesis. Most of the workshops will use a debian based Linux distribution such as Ubuntu, so it is also a great way to learn more about Linux as well as SDR.

The group has regular meetings at the REAST club house on the Domain once a month. Later on we will develop an SDR net and other online activities. Check the Upcoming Events page for information about our next meetup.
