Based on the data observed by a solar radio spectrometer at 2.6–3.8 GHz and other measurements at Shahe Station, we analyze the radio interference and its influence on observations. We have identified three different types of interference: (a) from antenna; (b) from IFs; and (c) internal signals, etc. Corresponding measures can be taken to reject or correct these errors and to improve the observations.
