SOFTWARE RADIO TECHNOLOGY PLC                         

                           ("SRT" or the "Company")                            

                     US$650,000 AIS Class B Order Received                     

SRT is pleased to announce that its subsidiary, SRT Marine Technology Limited,
has received and delivered an order for AIS Class B units worth US$650,000 from
TCB in China.

AIS is being used by China to improve coastal safety and security as part of a
national programme involving over 200,000 vessels. SRT's low cost and proven
AIS products enable TCB to offer a locally assembled and customised solution
which meets specific local requirements.

SRT has already supplied several thousand units to TCB as part of the national
rollout and expects that further long term orders will follow as this rollout
gathers pace. However the exact timing of further orders remains unknown.

Simon Tucker, Group Managing Director said, "We have worked with TCB for
several years and are delighted to have received this order. National
programmes with AIS at their core are increasing and this order demonstrates
the level of demand for our products which they create."
