SOFTWARE RADIO TECHNOLOGY PLC

                             Fundraising of £2.56m                             

Software Radio Technology plc ("SRT" or the "Company") (AIM: SRT) announces
that it has conditionally raised up to £2.56 million (approximately £2.48
million, net of expenses) via the issue of 9,500,000 new ordinary shares of
0.1p each (the "New Shares") at a price of 27 pence per share (the "Placing
Price") (the "Placing").

The funds raised in the Placing will be deployed to fund working capital to
support the existing product development road map and forward production and
stock commitments for the Company's current pipeline of opportunities.

Commenting on the Placing, SRT Chief Executive Simon Tucker, said: "SRT has
made exceptional progress over the last few years laying firm foundations for
future, sustainable growth. We have new products, more customers and a clearer
view of a significantly expanded range of market opportunities: some of which
appear to be of very significant size and nearing fruition. The markets we are
addressing mean that we need to maintain our product development momentum
whilst also having supply capacity to meet expected day-to-day customer
requirements. The Placing was done at the market price and significantly
oversubscribed. We are delighted by the response of our existing institutional
shareholders and welcome the opportunity to add a number of significant new
shareholders to the register."

Details of the Placing

The Placing has been conducted at the closing mid price of 27 pence per
ordinary share on 12 April 2012, being the last trading day before this
announcement. 

The New Shares will rank pari passu with the Company's existing ordinary
shares.  Application will be made for the New Shares to be admitted to trading
on AIM and it is expected that admission will become effective on or around
Monday 16 April 2012. Following the issue of the New Shares there will be a
total of 115,659,774 ordinary shares of 0.1p each in issue with each share
carrying the right to one vote. The above figure may be used by shareholders as
the denominator for the calculations by which they will determine if they are
required to notify their interest in, or a change to their interest in, the
Company under the FSA's Disclosure and Transparency Rules.
