My Credentials

We are all a sum of our experiences whether self-learnt or influenced by others through our journey in life. The information below represents my journey and will hopefully shed some light on my background.

Professional Career

I have always believed that the true record of a career is based on the contributions and achievements one makes and the people one influences rather than the name or size of a particular organization.  Whilst I have worked in various organizations of various sizes I have mostly enjoyed those who presented with complex challenges often hindered by budget constraints and those organizations who permit and appreciate innovation.

baycom-1200As a struggling student I was forced to originate my own 1200bps radio modem in order to play with the ‘big boys’ on amateur radio.

Using a handful of available decoder/encoder microchips, a custom modem driver and some downloadable software I was able to access radio-based PC’s for a number of years until the Internet essentially eroded this interest.
vk2ispFrom an early age I had maintained a healthy interest in digital signal processing. Slow-scan television is a means to encode and decode images by modulating a picture, line-by-line, in to several spectral bands.

Images are ‘scanned’ three times. Once for red, another for green and finally blue with each given a particular audio tone to indicate intensity. Over time this creates a melody of audio tones which is received by a corresponding decoder and converted to an image. Typically these images would be send on HF radio across continents.
NA1ISSSpaceCam 1 was a lengthy project between MAREX and NASA to place amateur radio slow-scan television aboard the International Space Station (ISS) in an effort to have school students and hobby groups receive continuous images from the station as it passes during orbit.

Audio ProcessingI have a healthy obsession with trying to make music as loud and consistent as possible without introducing distortion, artifacts or removing from the natural dynamics of the sounds. This has led me on an extensive journey of discovery in the field of digital signal processing and one which I still enjoy and actively pursue to this day.
