SOFTWARE RADIO TECHNOLOGY PLC                         

                           ("SRT" or the "Company")                            

                         Placing to raise £2.5 million                         

                              Holdings in Company                              

The Directors of SRT, the AIM-quoted developer and supplier of maritime
identification and tracking technologies, are pleased to announce that the
Company has carried out a placing through its broker, Westhouse Securities
Limited ("Westhouse"), of 6,250,000 new ordinary shares in the Company at a
price of 40p per share, raising £2.5 million (before expenses) (the "Placing").

Background to the Placing

SRT is seeing increasing demand for its AIS (Automatic Identification System)
solutions as existing national mandates start to take effect. The AIS market
remains in its early stages and is driven by multiple factors from commercial
imperatives to homeland security programmes. These drivers are creating
significant opportunities for SRT and its customers.

The funds raised in the Placing will allow the Company to accelerate planned
product development and provide working capital to improve product delivery
times for customers.

Simon Tucker, CEO of SRT, commented, "We are delighted to have secured this
funding and welcome some new and significant names to our share register. The
additional funding will enable us to capitalise further on the multiple
opportunities we see developing in the global AIS and vessel tracking markets.

"Specifically, the funds will enable us to accelerate our planned product
developments and launch our new Identifier and MOB (man over board) products in
2011, instead of 2012 as originally planned and expand our sales activities
across all markets. The funds will also provide additional working capital to
improve lead times and supply chain flexibility for our existing range of
products and to support our customers coping with high market demand."

Details of the Placing

The Company has placed 6,250,000 new ordinary shares of 0.1p each (the "Placing
Shares") at a price of 40p (the "Placing Price") raising £2.5 million (before
expenses). Admission of the Placing Shares to trading on AIM ("Admission") is
expected to occur at 8.00 a.m. on 16 November 2010.

The Placing is conditional, inter alia, on Admission occurring by not later
than 8.00 a.m. on 16 November 2010 (or such later time and/or date as Westhouse
and the Company may agree but in any event not later than 5.30 p.m. on 30
November 2010) and the placing agreement entered into between the Company and
Westhouse not having been terminated prior to Admission.

Following the Placing there will be 104,522,107 ordinary shares of 0.1p each in
issue.
