The intricacies of the pulsar radio emission physics in their plasma-filled magnetospheres remain poorly understood despite more than 55 years of active research. This is partially because the pulsar radio emission exhibits rich and complex phenomena, especially at the single-pulse level. While understanding the pulsar wideband emission physics is important in its own right, it will also have implications for other likely related time-domain phenomena, such as fast radio bursts (FRBs) or the recently discovered long-period transients (LPTs). In my presentation, I will focus on how the single-pulse modulation properties of radio pulsars change across the pulse window and how they vary with radio frequency. These are important observables to understand the energies of the emission-producing particles and constrain possible acceleration mechanisms. In particular, I will present our first results from the 'Science Using Single-Pulse Exploration with Combined Telescopes' (SUSPECT) project, which is currently running at the Nançay Radio Observatory in France (NenuFAR, LOFAR) and the uGMRT in India. Here, I will primarily concentrate on the results from our phase-resolved modulation index and pulse-energy distribution analyses of a subset of our current three-band data set. My discussion will include the pulsars' nulling behaviour, the number of emission components, their statistical distribution parameters, and how those vary with radio frequency. I will also comment on the new data analysis techniques we have developed as part of this work. The poster was presented at the Pulsar 2025 conference in Sardinia, Italy.
