Welcome to the amateur radio website of Peter Miles, VK6YSF.
The purpose of this site is to promote amateur radio and serve as a platform to document and share my various radio activities and projects.
Currently residing in the Town of Northam, located approximately 80km east of the City of Perth in Western Australia, I relocated here from Melbourne, Victoria in October 2007 to assume a position with the state electricity utility as a distribution designer.
I obtained my amateur radio license in June 1979 under the call sign VK3YSF, which I held until October 2007. Following my move to Western Australia, it became necessary to adopt a call sign reflecting the new state, and thus I chose VK6YSF. I'm not one for unnecessary change.
Throughout the years, I have actively engaged in the VHF/UHF portion of the radio spectrum, with specific interests in amateur radio satellites, as well as more recently, the HF (High Frequency) bands.
Aside from my passion for amateur radio, I have diverse interests including hiking, rock climbing, caving, photography, astronomy, home renovating, and gardening.
