(Work in progress … really!) The PicoRX was introduced to the MWRS at the June 2025 Lecture as one of the projects for the shack. Since then, many members have ordered and acquired the kit and started the build process. A Buildathon was organised for those who wished to build their PicoRX together in a […]

June 2025 – Lecture – Build Projects for the Shack
The June lecture, Build Projects for the Shack by Richard VK2ARH and Simon VK2YU, introduced two new club projects: an NTP (Network Time Protocol) Clock for the shack, and Pi-PicoRX, a software-defined radio receiver based in the Raspberry Pi Pico microcontroller. You can watch the lecture on VK2MB-TV. The lecture proved very popular, and another […]
July 2024 lecture: VK2MB KiwiSDR
If you haven’t yet tried the Society’s KiwiSDR receiver, you’re in for a treat. We’ve “customised ours for Australian conditions” so you’ll find features there that you won’t find on other web SDR receivers. This lecture by Richard VK2SKY explores everything from basic use to some of the lesser-known functions, and reveals many handy shortcuts to […]
13-Apr-2024 Working Bee
Saturday was a perfect day for doing some antenna work and other maintenance: sunny, not too warm, and with the predicted rain showers choosing to fall elsewhere. Just as well, as we had a lot of jobs to get through! The team managed to get through nearly all of the work items, but a couple […]
The Kiwi has Landed!
Listen to our new KiwiSDR at http://websdr.mwrs.org.au:8073, and watch the July 2024 lecture, VK2MB KiwiSDR Secrets to learn how to use it. It’s been a long wait, but the Society is back in the webSDR business! For those who have never used one, a webSDR is a web-connected Software Defined Radio, accessible from anywhere on […]
Building an outdoor ADS-B receiver
Article by Simon Mitchell – VK2YU Overview The aim of this project was to build an ADS-B receiver using the popular PiAware implementation (created by FlightAware). The installation and configuration of PiAware is very well documented so I will not elaborate on this in this text only to point interested people to FlightAware’s PiAware URL: […]
µBITX project
Just had to build one of these www.hfsignals.com/index.php/ubitx/. So here is my µBITX project, for the price of 2 crystals for a Codan lunch box, I get a full HF rig! It had to go into an ammunition box, a bit tight in one of the dimensions, and if I was to do this again, […]
January 2017 Lecture – ICOM 7300
Now I need to buy one! View the lecture on VK2MB-TV! The ICOM 7300 session/lecture was originally planned for the HF Month – March 2017 – however as the Wyong field day is at the end for February and many members wanted a reason to grab one at the field day, a lecture/review of the […]
MWRS WebSDR Build Completed
The MWRS WebSDR is now online! After a year-long effort by generous volunteers, all the bits are connected together, a linear power supply has been built and the loop antenna is professionally installed. A huge thanks to everyone who has helped with this project, it’s great to see it online. Matt VK2RQ, Phil VK2BDF and Horst VK2HL helped […]
MWRS WebSDR Build – Part 2
Our WebSDR build is progressing well, after the first installment we had finished the construction of 3 x Softrock RX III kits. These have all been brought together on the bench and compared to each other using SDR# and one of the Asus Xonar U7 sound cards. The first 3 units are working well and construction […]
MWRS WebSDR Build – Part 1
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 […]
