J.AbsorciónDesvanecimientoIonosferaAbsorptionFadingIonosphereA commercial computer controlled radio receiver has been used to measure signal strength of High Frequency (HF) signals in order to study the effects of geophysical events on radio communications and to test the system for ionospheric monitoring. The system was installed at the Southern Space Observatory (OES/CRSPE/INPE) in Sāo Martinho da Serra, Brazil (29.43°S, 53.8°W, B = 23350 nT). Initial results show that this system is able to detect ionospheric radio absorption events. The commercial radio receiver has a computer serial interface, to control the reception frequency in order to acquire the values of the received signal strength. We describe the system and some initial results on radio absorption events associated to C and M classes of x-ray solar flares. The results suggest the possibility of using this low-cost system to study the daily variation of the lower ionosphere ionization and to stuy events of ionospheric absorption. Long period measurements give statistical information about the magnitude and time scale of fading, that can be used for planning radio links.Hemos usado un receptor comercial de radio controlado por una computadora para medir Ia intensidad de las seiiales en el rango de las altas frecuencias, con el objeto de estudiar los efectos de los eventos geoffsicos en las radio-comunicaciones y probar este sistema parae! monitoreo ionosferico. El sistema se instal6 en el Observatorio Espacial del Sur (OES/CRSPEIINPE) localizado en Sao Martinho da Serra (29.43°S, 53.8°W, B = 23350 nT) en el sur de Brasil y ha probado que puede detectar eventos de radio-absorci6n ionosferica. El experimento consiste en un radio receptor comercial con una computadora de interfase en serie, que hace posible controlar Ia recepci6n de frecuencias y conocer Ia intensidad recibida. Este reporte describe el sistema y presenta resultados iniciales obtenidos principalmente sobre absorci6n de eventos asociados con r:ifagas solares de las clases C y M. Los resultados preliminares indican que este equipo de bajo costo se puede usar para estudiar Ia variaci6n diaria de Ia ionizaci6n de Ia baja ionosfera y los eventos de absorci6n ionosferica. Ademas, las mediciones a largo plazo dan informacion estadistica sobre Ia magnitud y tiempo de Ia desaparici6n de seiiales; esto se puede usar para planear los contactos entre diferentes ernisoras de radio.Universidad Nacional Autónoma de México.
