Frits van Enk B. Elec Eng

Consulting Engineer and Specialist Advisor

Frits van Enk, founder of RST,  is a Professional Engineer who graduated in Electronics Engineering from the Technical University in Delft, Holland, in the early 70’s. Following his graduation he served for 2 years in the Royal Dutch Navy as a Communications Officer.

Frits commenced his professional career with Philips Telecommunications Industries in Hilversum, Holland, where he worked in various areas of Mobile and Military Radio research and development.

In the mid 70’s he was seconded to the Philips Radio Communications Division in Melbourne, where he became Engineering Manager, responsible for all Product and Systems Development. He was directly responsible for a number of highly successful product developments, including the world famous FM828/FM813 series of mobiles, the FM814/FM815 series of Base stations, and last but not least, the FM320/620 UHF CB radio, of which close to 100,000 units haven been produced.

He left Philips Australia in the late 80’s, to join Signalling Technology, where he served for a period of 5 years, mainly in the position of Engineering Manager. He then joined the GEC-Plessey/Sepac Telecommunications Division in Melbourne, again as Engineering Manager, responsible for all product and system development. It was at GPT that he became very involved with major systems development and production, especially concentrating on Trunked radio systems.

Following a GPT management decision to close down their Radio division, he took over ownership in the early 90’s, and re-started the Company as Radio Systems Technologies. Frits is still very active today in all aspects of the Company’s operations, but his main interest is and remains Radio Systems Engineering.

His main Engineering achievements at RST are the development of the world famous and internationally highly successful Cell Extender and SmartBridge product range, which he developed almost single handed, greatly assisted by his Engineering friend and colleague Peter Stephens, who developed all the software for these products.

Whilst RST has been acquired by the JRD Group, Frits continues his involvement as a Consulting Engineer and Specialist Advisor.
