Abstract : Observations with high time resolution (< 1 ms) have been made in the frequency range 30-82 MHz. During June 1979 several thousand bursts with bandwidth of approx. 100 kHz drift rates were between -1.5 and -5 MHz 1s. They belong to the classification 'fast-drift storm bursts' (FDS bursts). Approximately 1% of the bursts in the present observations showed bands or fringes in the frequency-time plane almost parallel to the time axis and with a frequency separation of about 100 kHz. Examples of FDS bursts and FDS bursts with fringes are provided. The presence of fringes and their short duration at a single frequency are also considered.
