                       New US$900,000 AIS Order Received                       

Software Radio Technology plc ("SRT" or the "Company") is pleased to announce
that it has received a repeat order from an existing customer worth
approximately US$900,000.

This order increases SRT's order book value as at 6 December 2010 to US$8.1
million, the majority of which is expected to be delivered within the current
financial year.

The order has been received from an existing customer who has been supplying
SRT's Class A product primarily into EU commercial markets. There are a number
of mandates now in effect in the EU which require certain types of vessels to
fit AIS devices. The two largest are the Inland Waterway mandate which requires
most commercial vessels operating along the Rhine to install an AIS device by
2012 and the EU fisheries mandate which requires all commercial fishing vessels
in the EU to fit an AIS device by 2014. Together these mandates affect over
40,000 vessels, of which SRT estimates approximately 20% have been fitted to
date.

Simon Tucker, SRT's Chief Executive Officer, said: "The two major EU mandates
are only one segment of the global AIS opportunity that SRT and its partners
are addressing. We seek to work closely with each of our partners to maximise
their success in their particular target market segment. As demonstrated by
this new order, our strategy of long term investment in technologies, products
and partnerships is working as the demand for AIS devices grows. We continue to
deliver daily against our order book and regular customer orders as well as
meeting the challenge of targeting new markets with our partners."
