SOFTWARE RADIO TECHNOLOGY PLC AIS CLASS B US COAST GUARD APPROVAL

The Directors of Software Radio Technology plc ("SRT" or the "Company") are pleased to announce that SRT has received US Coast Guard ("USCG") approval for its AIS Class B transceiver.

At the end of 2006, SRT launched the world's first low cost, AIS standard compliant AIS Class B transceiver designed for use by small commercial and leisure boats. AIS enables accurate and reliable identification and tracking of maritime traffic and is now an integral element of many countries' homeland security strategies.

SRT is working with a growing customer base of over 20 companies around the world to launch a range of AIS Class B products during 2007.

Simon Tucker, SRT's Managing Director said; "SRT has achieved a world first by obtaining USCG approval for our Class B solution. The USCG is a supporter of AIS and we believe this paves the way for the wider rollout of AIS. With over 12 million boats in the US alone, this is clearly a very exciting prospect for us."
