For over four decades the VK2RDX 2m repeater at Mt Bindo, has provided coverage from Sydney across the Blue Mountains and west to Bathurst and Orange. Overtime the repeater's performance did decline, so in recent years a team of dedicated amateur radio operators from Sydney and Bathurst areas, have been working to restore and improve the VK2RDX site. The work included removing rust and corrosion causing passive inter-modulation issues and receiver de-sensing, refurbishing antenna systems, replacing the original "REX" 2m repeater with a newer ex-commercial equipment, new customised repeater controller based on the design by John Drew VK5DJ and upgrading and expanding power supply capacity.

Due to interference issues, the VK2RDX 2m FM repeater will be fitted with CTCSS tone of 91.5 Hz decode to the receiver from early July2023. Simply add 91.5 Hz CTCSS sub tone encoding to your transmitter. 

On Sunday, the 2m FM repeater re-broadcasts the morning and afternoon news from the studios of Amateur Radio NSW in Dural. The previous weekend saw the most call backs for the last 12 months, following the morning broadcast. With the assistance of Amateur Radio NSW, the repeater team have also installed a 70cm DMR repeater, part of the RadNet and VKDMR networks, operating on 438.1500 MHz with a input frequency of 431.1500 MHz.

All amateur radio operators are welcome to use the VK2RDX repeaters. The VK2RDX site is sponsored by The St George Amateur Radio Society.
