VK4VU VHF/UHF/Microwave Pages


About Me

I obtained my amateur radio licence in 1974 whilst still in high-school. My interest was largely directed towards VHF DX operation, which meant that I gained some early experience in designing and building preamplifiers, converters, amplifiers and antennas.

Because of my keen interest in radio-communications technology I decided to pursue a career in this interesting field. My current professional role is directly involved with developing spectrum strategy for 5G mobile networks and other emerging technologies.


Amateur Radio activities

My primary interest is in weak signal communication on the VHF, UHF and microwave amateur radio frequency allocations.
