Neutron stars observed as radio pulsars exhibit many complex phenomena at the single-pulse level. Despite more than 55 years of active research, the intricacies of their radio emission remain poorly understood. In my talk, I will describe the SUSPECT (Science Using Single-Pulse Exploration with Combined Telescopes) project that we have been running at the Nançay Radio Observatory Telescopes (mainly NenuFAR & LOFAR FR606) in France and the upgraded GMRT in India since early 2023. In particular, I will discuss how our new simultaneous multi-telescope, multi-frequency observations constrain various properties that characterise the pulsar radio emission mechanisms to unveil the physical processes operating in pulsar magnetospheres. I will present some of the first and most striking results we have obtained from our sample of more than 20 radio pulsars, where I will focus on mode-switching and unusual single-pulse emission. Finally, I will comment on how this work paves the way towards the SKA era. The slides were presented at the 2024 AstroRadioFr24 conference in Paris, France.
