About Us


The Bayside District Amateur Radio Society (BDARS) is centred in the bayside area of Brisbane.  We welcome those interested in amateur radio, short wave listening and related electronic communications.  The interests of our members are diverse – covering HF, VHF, satellites, homebrewing, digital techniques and even good old ragchewing.

Foundation Licence Course

Following the change in amateur radio licencing in Australia, BDARS will not be running the previously advertised Foundation Licence course.

Update December 25th 2018 – Mt Cotton Repeater VK4RDB changes:-

The FM VHF repeater frequency has changed to 146.875MHz. The offset is -600KHz and it requires a 91.5Hz CTCSS tone to enable its use.

The UHF repeater on 438.450MHz has been upgraded and now has mixed mode capability. It will automatically switch between FM and Digital voice Yaesu System Fusion (Wires-X). It emits a 91.5Hz tone on FM voice which can be used  to stop the digital C4FM noise when only listening in FM.

Update September 2018 – Alexandra Hills Repeaters VK4RBS are Off The Air

After many years of use, the club’s repeaters at Alexandra Hills were turned off on 14 September 2018.  This was due to the site owner investigating the refurbishment of the water tower which hosted our repeaters.  BDARS’ new repeaters (VK4RDB) are being installed at a new location at Mt Cotton.  Currently, the 70 cm repeaters are operational in test mode.

The wonderful hobby of amateur radio encompasses about three million people worldwide and is a truly international pastime.

The aim of our Society is to progress amateur radio locally through training courses and accreditation examinations for those interested in joining the hobby. We like to attract young and old alike and develop technical skills across a wide range of activities by holding regular meetings and events.

We assist our members with our Member’s Shop (bulk purchase of items like coax and connectors). In addition, we have a small collection of high quality test gear available for member’s use.

You are very welcome to come and meet our members or contact us via the internet or by telephone. Our New Members Handbook with membership application form is here on our website. You can email the form to the secretary or send via Australia Post to our PO Box 411 Capalaba Qld 4157.

In 1991, the Society installed a VHF repeater VK4RBS transmitting on 146.875MHz at Alexandra Hills to extend the local area amateur coverage. A UHF repeater also with callsign VK4RBS, transmitting on 439.725MHz was donated and installed by club member, Russell Walker VK4DCM in 2009. Echolink (on the UHF repeater) and IRLP (Node 6633) operates on the VHF repeater. Your mobile phone can access Echolink via an app.

In August 2018 the society began an exciting project to commission three new repeaters located on Mount Cotton. More information can be found in the Blog section of this website.

The inaugural meeting of the Bayside District Amateur Radio Society was held at Alexandra Hills State High School on Friday 20th October 1989. There were 32 members and the first president was Don Thompson, callsign VK4YI (silent key) at that time.
