Resumen:
We present the current status of the flux calibration of the Radio Telescope Esteban Bajaja fromthe Instituto Argentino de Radioastronom´ıa (IAR). We made observations of a noise source (MC7014 ENR 35dB)and of well-known astronomical sources, such as Fornax A. The observations consisted of scans on right ascensionand declination, centred at the position of the sources. During each scan, the power of both linear polarizationsignals was registered, switching between the astronomical source and the noise source. We made the observationsusing the new receiver with a ROACH board, which replaces the old ETTUS boards. The central frequency was1420 MHz, with a total bandwidth of 400 MHz and a maximum integration time of 600 ms.
