The Lyrids meteor stream has a medium activity and its
origin is cometary. The stream occurs in the last days of April and the maximum of activity occurs in the days 22-23 April. The Lyrids were studied in 2007 using radio observations. The radio data were obtained using the meteor scatter techniques. The activity of the stream has been analyzed using the method SVB. This method allows to separate from the observed datas the sporadic activity and the observability function of the forward-scatter apparatus and from these to obtain the true activity of the stream. The data were taken from the Radio Meteor Observation Bullettins. The purpose
of this analysis is the definition of the main characteristics of the stream. The solar longitude of the maximum of the activity is λ0 = 32.4° ± 0.2°.
