The National Laboratory of Space Weather in Mexico (Laboratorio Nacional deClimaEspacial: LANCE) coordinates instrumentation for monitoring thespace-weatherimpact over Mexico. Two of these instruments are the Mexican ArrayRadio Telescope(MEXART) and Compound Astronomical Low frequency Low costInstrument for Spectroscopy and Transportable Observatory(CALLISTO) stationfrom the e-CALLISTO network (CALLMEX). Both instruments are located at the samefacility(Coeneo Michoacan, Mexico) and share a spectral band centered at 140MHz. In this work we show the capabilities of the e-CALLISTO network as supportto identify a solar radio burst in the signal of the MEXART radiotelescope. Weidentify 75 solarradio bursts in the MEXART signal: five events of Type II and70 of Type III between September 2015 and May 2019. The analysis of solar radiobursts in the MEXART signal provide us valuable information about thedevelopment of the radio event due their high sensitivity, time resolution, andisotropic response. For the case of Type III solar radio events, we identifythree characteristic phases in the dynamical evolution ofthe signal at 140 MHz:a pre-phase, a main peak, a decay phase, and a post-event phase.A Morlet wavetransform was done of MEXART signals in the Type III solar radiobusts; in theirspectra it was identified a pine tree structure preceding the main event in thetime series. These characteristics are not observable in the data from thee-Callistonetwork.
