Abstract: Chains of type I are associated with the Radio Noise Storms (RNS). We report the analysis of the parameters of the two RNS: one associated with the occurrence of solar flares in X-rays and one recorded on a day without the presence of a flare. The spectral information about the chains in these events were obtained from the e-CALLISTO (Compact Astronomical Low-cost Low-frequency Instrument for Spectroscopy and Transportable Observatory) network. On 07/May/2011 (day without flare) the bandwidth was in the range 5.7 - 91 MHz, the duration varied from 7 - 361 seconds, and the drift-rate frequency was in the range -5.2 - +2.5 MHz s-1. The day with flare (01/August/2011) had bandwidth in the range of 4.7 - 60 MHz, duration between 6 and 214 seconds, and frequency drift-rate varying from -6 to +1.8 MHz s-1.
