capitalised marine development costs.

SRT Chairman Nick Jolliffe said: "SRT Marine has continued to grow through the
provision of its Automatic Identification System ("AIS") technology and OEM
product solutions to a global customer base. Revenues from continuing
operations increased by 15% to £2.5 million (2008: £2.2 million) with a gross
margin of 38% (2008: 37%).

"During the year we worked with our growing customer base to embed our
solutions into a wide range of AIS products and support their launch into the
market. We also broadened our AIS product range.

"We have further increased both the number of our customers and the
distribution of `SRT inside' products throughout the marine market. Our mission
of providing a high quality, low cost solution coupled with an aggressive
solution-provider strategy, has enabled us to become the primary global
supplier of AIS to the trade."

                FINAL RESULTS FOR THE YEAR ENDED 31 MARCH 2009                 

The Directors of SRT, the AIM-quoted developer and licensor of advanced
wireless radio communication technology engines and the provision thereof in a
variety of flexible formats, are pleased to provide the preliminary
announcement of the results for the year ended 31 March 2009.

CHAIRMAN'S STATEMENT

At the start of the financial year the Software Radio Technology plc group
comprised two subsidiaries: SRT Marine Technology Limited ("SRT Marine") which
continues to make significant progress and is the main focus of this report and
SRT PMR Technology Limited ("SRT PMR").

The harsh economic environment has affected the Group and its partners and in
December, SRT PMR went into Administration when, following delays in the
project and specifically in payments from customers, it was not possible to
secure the additional finance required to continue to trade. Although SRT has
retained ownership of the TETRA Intellectual Property Rights ("IPR") and is
seeking to generate value from this asset, the Administration of SRT PMR
resulted in a loss of approximately £11 million.

SRT Marine has continued to grow through the provision of its Automatic
Identification System ("AIS") technology and OEM product solutions to a global
customer base. Revenues from continuing operations increased by 15% to £2.5
million (2008: £2.2 million) with a gross margin of 38% (2008: 37%). An
operating loss was incurred from continuing operations of £1.3 million (2008: £
0.6 million) before share based payments. This loss includes development costs
and amortisation of £1.1 million (2008: £0.4 million).

Operational Review

Our primary focus is the expansion of SRT Marine which has established itself
as the global leader in the provision of AIS technology and product solutions.

During the year we worked with our growing customer base to embed our solutions
into a wide range of AIS products and support their launch into the market. We
also broadened our AIS product range. Our patented antenna splitter, which
simplifies the installation of AIS through enabling the sharing of a single
antenna with existing VHF radios, has received an excellent response from the
market with our first production run selling out before it was completed. We
have further increased both the number of our customers and the distribution of
`SRT inside' products throughout the marine market. Our mission of providing a
high quality, low cost solution, coupled with an aggressive solution-provider
strategy, has enabled us to become the primary global supplier of AIS to the
trade.

As a result we saw 15% growth in revenues within SRT Marine, despite mandate
delays and slow leisure markets and achieved a gross margin of 38%.

In non-mandate markets we are working actively with our partners to formulate
marketing campaigns to increase the awareness of AIS. Despite the global credit
crisis, where these have been implemented we have seen a slow but steady
increase in sales.

Interest from authorities in mandating AIS has continued to grow. China,
Turkey, India, the EU and USA have all announced mandates of varying sizes. As
with many government projects, the timing of implementation is difficult to
predict, however as the world's leading provider of AIS solutions, SRT Marine
stands to generate significant revenues when these mandates take effect.

During the next 18 months we will launch two new products, a Class A unit and a
low cost Dual Channel Receiver, which will complete our core AIS solution
offering. The Class A unit is primarily targeted at commercial vessels where
mandates commencing in 2010 have been announced. The receiver-only product is
aimed at providing a first, low cost step on the AIS ladder for non-mandate
markets. We believe that our technology and development expertise will enable
us to create a low cost, high margin product which will generate significant
revenues in the future.

SRT's in-house development team has world class radio development skills and
significant AIS experience. The team has a track record of delivering high
quality, high performance solutions. With disciplined management, we are
confident that we will continue to provide our partners with the AIS products
to address the market.

Board Composition and Governance

The financial year saw several changes to the board. Finance Director, Matthew
Rogers left in December 2008 and Chairman, Richard Moon, resigned in February
2009 with Nick Jolliffe appointed as Chairman. Dr George Kyprios left the board
following the administration of SRT PMR. I would like to record here the
Board's gratitude for their contribution. There are no plans to replace these
directors as the Group is smaller now and the Board maintains a suitable
balance of skills.

Employees

The Group operates in challenging markets and technologies, which in turn,
places large demands on our staff. We are fortunate in having an expert and
dedicated workforce which has enabled us to progress. I would like to thank
them personally and on behalf of the Board for their continued hard work and
support.

Strategy and the future

SRT's primary focus will be its Marine business, which will continue to broaden
its range of AIS technologies and products to meet growing international
demand. The Group has built an excellent international reputation for
delivering solutions of the highest quality and performance at a competitive
price.

AIS market opportunities have clarified and increased during the last year. We
expect that non-mandated markets will continue to grow slowly, whilst mandates
are only likely to have a substantial impact in 2010. However, we believe that
the outlook for 2010 and beyond is positive and that the investment in
developing our AIS product range, and securing sales channels will deliver
significant long term returns.

The coming year will inevitably be challenging given the state of the world
economy, but we expect to see continuing growth in the Marine business and a
meaningful contribution from the residual TETRA business.
