Statement re: FCC Approval

SOFTWARE RADIO TECHNOLOGY PLC                         

                                 FCC APPROVAL                                  

On 11 April 2007, Software Radio Technology plc ("SRT" or the "Company")
announced that the Company's AIS Class B transceiver had received approval from
the US Federal Communications Commission (the "FCC").

The Company has been notified by the FCC that the approval certificate granted
and provided to SRT was issued in error and a certificate should not have been
issued at that time.

The FCC has advised SRT that the grant of the approval was an administrative
error and various matters are still under consideration. The FCC has further
advised SRT that there is an approval waiver process which can be applied for
in the short term which may enable the AIS Class B technology to be sold in the
USA prior to full FCC approval being granted. SRT intends to pursue this route.

The Company remains confident that full FCC approval will be granted in due
course and understands that the matters now under consideration relate to the
FCC's rules governing the deployment of significant numbers of AIS Class B
units.

Simon Tucker, SRT's Managing Director, said: "The granting of the approval
earlier this week was well ahead of our expectations and it is naturally
disappointing that this was due to an error. We are taking the necessary steps
to apply for the waiver from the FCC and anticipate gaining full FCC approval
within our original timescales."
