                     Commencement of AIS Mandate in Turkey                     

Software Radio Technology plc ("SRT" or the "Company") is pleased to announce
that it has received orders of US$290,000 for AIS modules following the
commencement of a mandate for certain commercial vessels in Turkey to be fitted
with AIS transceivers.

The mandate requires approximately 15,000 commercial vessels to fit a
customised AIS transceiver over the next 18 months. The objective of this
mandate is to improve maritime safety and security.

SRT has formed agreements with strategic partners who will use SRT's range of
AIS modules to manufacture locally AIS transceivers which meet the required
specification.

Simon Tucker, SRT CEO said, "This order represents less than 10% of the total
market opportunity created by this mandate and given our partnerships in this
country we expect there to be more significant orders in the coming year. We
have been working with our Turkish partners for over two years and we are
delighted that the mandate has now come into force. We hope that this could
provide the foundation for wider mandates in Turkey and nearby countries in the
future."
