N2 - Two radio spectrometer stations belonging to the e-CALLISTO network were installed in Peru
by the Astrophysics Directorate of CONIDA. Given their strategic location near the Equator, it
was possible to observe the Sun evenly throughout the whole year and the detector was unique
in its time-zone coverage. The receiver located nearby the capital city of Lima took data in the
metric and decimetric bands looking for radio bursts. To assess the suitability of the sites and
the performance of the antennas, we analysed the radio ambient background and measured their
radiation pattern and beam-width. To show the capabilities of the facilities to study solar dynamics
in these radio frequencies we have selected and analysed type III Solar Radio Bursts. We have
characterised the most common radio bursts with the following mean values: a negative drift rate
of -25.8 ± 3.7 MHz/s, a duration of 2.6 ± 0.3 s and 35 MHz bandwidth in the frequency range
of 114 to 174 MHz. In addition, for some events, it was possible to calculate a global frequency
drift, which on average was 0.4 ± 0.1 MHz/s.
