Vale - Steve Stebbing VK2AAV 1965-2025

Steve VK2AAV!

It is with great sadness that we announce the recent and unexpectedly sudden passing of Steve Stebbing, VK2AAV.

Steve was a committed Amateur and good friend to many. His work in Radio and Electronics spanned many decades. As a long-term member of the Hornsby and Districts Amateur Radio Club, he was a regular presenter, challenging us all to learn and refine our electronics skills. In 2024, he stepped up to become President of HADARC and ran the Club with new and interesting topics.

More recently, Steve applied his passion of engineering to design LORA and Meshtastic networks. In the past year Steve also designed online access to the HADARC Repeater for power management and enjoyed time on 6 meters and 2 Meter bands.

Steve will be dearly missed by many Amateurs.

Funeral Service: Friday 8th August @ 1PM in St. James Church, Turramurra – If attending contact Matt VK2BAI (0401 992 430) to allow for catering requirments. Live streaming is planned. Details later.
