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 the development of 4G and, more recently, 5G Mobile Networks.


Amateur Radio activities

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

Im currently focussing my attention on equipment for the 432, 1296 and 2400 MHz bands as well as learning a little about using Arduino boards for some control and monitoring applications.
