The Trieste Solar Radio System 2.0 (TSRS 2.0) is a new facility installed at the Basovizza Observing Station of the INAF Astronomical Observatory of Trieste. It is aimed at solar radio surveillance in the frequency range 1-19 GHz. Thanks to its peculiar and unique operational features, the system is an effective diagnostic tool and plays a key role in Solar Radio Weather monitoring. By an alt-az mount with a 3,7-meter parabolic dish and dual circular polarisation feeder, the hybrid SDR (Software-Defined Radio) radio spectropolarimeter has been operating at L, C, and Ku frequency bands, and at fixed frequencies (e.g., 2800 MHz) to  monitor solar radio emissions with high time resolution and full circular polarisation information by providing solar radio spectra and relevant solar radio indices at selected frequencies. Furthermore, it will produce synoptic radio maps of solar radio sources at 18 GHz by scanning technique. In this paper, we discuss the current status of TSRS 2.0 and present preliminary results in the light of Space Weather applications and Solar Radio Physics investigations via coordinated observations with other radio facilities such as, e.g., INAF non-dedicated, large single dish radio telescopes (SRT Sardinia Radio Telescope, Medicina, and Noto) and LOFAR (Low-Frequency Array).
