MWRS WebSDR Build – Part 1

Softrock RX III - finished!

What is a WebSDR and why make one? SDR means “software defined radio” – and the basic premise is that instead of homing in on one signal using a classic receiver, you can sample a substantial “chunk” of radio spectrum and then do whatever processing you like with it using software (all of the demodulation/filtering etc is […]

ILLW 2015 Wrap-up

Squid pole and EFHW

Another great year at Barrenjoey, with the traditional start at the coffee shop for a perk up.  Starters Dom VK2JNA, Geoff VK2TGO, Mike VK2UCT, Clint (VK2SOON!!) and Geoff VK2AVR met at the traditional rally point (coffee shop).  This year we augmented coffee with bacon and egg rolls, but our NPWS escort was waiting for us at Palm Beach […]

Arthur Gerald Sabin VK2AGS – SK

Gerry VK2AGS

Arthur Gerald Sabin (VK2AGS) passed away early on 5th August 2015.  He was our oldest and longest-serving member having joined in 1934, only a few years after our club’s foundation (1923)!  Gerald contributed much over his many decades of MWRS membership and will be greatly missed.

Following on from last month’s inaugural tech night, this month’s tech night was all about the Arduino!  We had many interesting demos and again attracted visitors from as far away as Newcastle.  Many thanks to everyone who brought projects to show off!  Mal VK2TMF brought his audio-activated tie, and an electric scooter package.  Marcel VK2HAQ brought his […]

Last night the club held its first “4th Wednesday” tech night. This month we turn out attention to the Raspberry Pi, and invited people to bring their projects and ideas along. Yves was kind enough to send out his take on the night This was an amazing idea! So many new faces, new interests and […]

VK2RMB gets wifi

VK2RMB gets wifi

A few years ago the club was lucky enough to be selected to host one of a handful of ICOM supplied D-Star repeaters. As D-Star uses the internet to link repeaters around the world it was necessary to have our repeater shack setup with an ADSL connection, which the WIA graciously funded until recently. We […]

Nerds and nutterts

d3c9d7ea8aaff4c1380d4fa111006f55

I am not a nerd – I just happen to have a very nerdy hobby: amateur radio! I have been playing with radios from the age of 13 or 14. I am still excited about building my own gear and antennas and making two-way Morse-code contacts with fellow nutters on the other side of the world. Time permitting, […]

Next Lecture April 15 – BALINT SEEBER – The ISEE-3 Rescue. & Software Defined Radio.

BALINT SEEBER – The ISEE-3 Rescue. & Software Defined Radio. Ever wanted to communicate with a NASA space probe launched in 1978, or spoof a restaurant’s pager system? There are surprising similarities! How about use an airport’s Primary Surveillance RADAR to build your own bistatic RADAR system and track moving objects? What sorts of RF transactions […]

Firstly a huge thanks to all those who participated in the event! We had a great weekend with club members and fellow amateurs raising the jolly roger across Australia.

CHA-250B review

com-cha250b_l

Comet’s CHA-250B is an interesting antenna. It claims (and delivers) continuous broadband coverage from 3.5MHz to 57MHz with no ground radials. Comet’s website admits this is not without its compromises of course:   “If you have the space, budget and desire to erect a full size antenna system we suggest you do so… bigger is better…however…if […]

Three band end fed antenna

Three band end fed antenna

Geoff VK2TGO recently gave a lecture on an end fed antenna for 40-20-10m.  This antenna is fed using a 9:1 unun, just under 13 metres of wire and a loading coil near one end.  The antenna wire itself can be deployed in many ways: vertically, as an inverted V (with the feedpoint at one of the low […]
