Recently several ground-based and space-based radio telescopes have been used to continuously monitor the radio transient emissions from the solar atmosphere. In order to study various properties of radio bursts, we need to calibrate them carefully and bring them to the uniform units. Using the improved calibration techniques, we have been working on to investigate the spectral response of type III bursts that are commonly observed from 20 kHz to 80 MHz using the Nancay Decameter Array (NDA), LOFAR, WIND/WAVES, and STEREO/WAVES. We would present the improved calibration techniques, cross-comparisons, and obtain preliminary results.
