Software Radio Technology PLC ("SRT" or the "Company"): Live Shareholder Webcast

LONDON, January 25, 2011 - On Friday 28 January at 7.15 a.m., AIM-quoted marine
electronics developer, SRT will host its first live shareholder webcast open
to existing and prospective private and institutional investors.

Simon Tucker, SRT's CEO, will provide responses to questions
through a live video webcast which can be accessed by any interested party
worldwide by visiting the website listed below.

    The format for the live webcast will be as follows:

    - Investors are invited to email questions prior to the event
      to investor@softwarerad.com. These questions will help form the
      presentation given by Simon Tucker on the webcast. Questions must be
      submitted before 6:00 p.m. on Thursday 27 January.

    - Investors will need to go to
      www.softwarerad.com/investorwebcast and login using a nickname
      and their email address. Please note that investor names and identities
      will not be broadcast and will be kept strictly confidential.

    - During the webcast, investors will be able to send instant
      messages from the viewing website to Simon for him to answer and react
      to live.

Simon Tucker commented, "Most AIM companies usually only meet
their shareholders at events like the AGM, but in fast moving markets, we
feel that once or twice a year is not enough. SRT has always tried to
communicate clearly with its very loyal shareholder base, and this webcast
takes that to the next level; allowing shareholders the chance to ask
questions on any topic they feel pertinent to the future of the Company.
Where possible, we will provide the answers.

"We hope to hear from many of our long term shareholders and
we look forward to outlining some of our plans for 2011."
