e-Callisto
International Network of Solar Radio Spectrometers, a Space Weather Instrument Array

The Callisto solar spectrometer is a programmable heterodyne receiver designed in 2006 by Christian Monstein, a member of the Radio Astronomy Group at ETH Zurich, Switzerland. Several Callisto receivers are installed worldwide and are part of the e-Callisto network. You can access the data for the entire network here

The Callisto MEXICO-UANL-INFIERNILLO station is located in the Galeana mountain range, Nuevo León. It is located in the Galeana Mountains, Nuevo León. The station belongs to the Faculty of Physical and Mathematical Sciences (FCFM) of the Autonomous University of Nuevo León (UANL). It is configured to monitor the 45-90 MHz band, at 200 frequencies, four times per second. It uses an LWA crossed dipole antenna. It also has a power coupler with a quadrature (LWAPC-Q) that feeds the crossed dipole antenna's active balun array through the coaxial transmission lines. The LWAPC-Q has two identical RF circuits and is inserted between the antenna array and the receivers. This allows for discrimination of circular polarizations received by linearly polarized crossed dipoles.
