Abstract
We report observations of the millisecond pulsar J0437-4715 at 76 and 90 MHz. These observations give a five-fold increase in the frequency range of measurements of this pulsar and provide the first record of t he pulsed emission from any millisecond pulsar below 100 MHz. We find that the radio spectrum of the mean pulsed emission of J0437-4715 is s imilar to that of many other pulsars with a spectral turnover between 90 and 400 MHz. J0437-4715 differs from most other pulsars with respec t to the variation of pulse width with radiation frequency and the rel ative spectra of pulse components.
