Resumen: We present the current status of the flux calibration of the Radio Telescope Esteban Bajaja from the Instituto Argentino de RadioastronomÃa (IAR). We made observations of a noise source (MC7014 ENR 35dB) and of well-known astronomical sources, such as Fornax[aprox.]A. The observations consisted of scans on right ascension and declination, centred at the position of the sources. During each scan, the power of both linear polarization signals was registered, switching between the astronomical source and the noise source. We made the observations using the new receiver with a ROACH board, which replaces the old ETTUS boards. The central frequency was 1420[aprox.]MHz, with a total bandwidth of 400[aprox.]MHz and a maximum integration time of 600[aprox.]ms.
