assuming DMs of $1165 \pm11$, $278\pm3$ and $682\pm7$ pc cm$^{-3}$ respectively. The data are uncalibrated as the bandpass of the system varies as a function of meridian angle, and the flux densities are in arbitrary units.

![Frequency vs time behaviour of FRBs 160317, 160410 and 160608 detected at UTMOST at the centre frequency of 834.765 MHz. The top panel in each case shows the frequency-averaged pulse profile. The bottom panel shows that narrow-band RFI has been excised and the effects of inter-channel dispersion have been removed assuming DMs of $1165 \pm11$, $278\pm3$ and $682\pm7$ pc cm$^{-3}$ respectively.
