We have extended the database of flux density measurements of 280 pulsars made by Lorimer et al. (1995) to frequencies higher than 1.4 GHz and lower than 300 MHz. Our analysis shows that the spectral behaviour of the majority of pulsars can be well described by a simple power law (S ~ υα where = −1.8) though some pulsar spectra are described by a ”broken power law” with a break at high frequencies υb ~ 1.8 GHz.
