We present observations and processing of the March 29, 2006 solar eclipse data at the radio telescopes RT-3 (λ = 4.9 cm) and RT-2 (λ = 3.2 cm) of the Kislovodsk Solar Station of the Pulkovo Astronomical Observatory of RAS. Registration of the emission flux was conducted by electron method with a time resolution of 0.5 s. Compact sources on the solar disk are identified, and the contribution of coronal holes into the integral flux is determined. Comparisons to observations in the optical and X-ray ranges are performed. The intensity of sources behind the solar limb is estimated. The ratio of the intensity of residual radiation in the maximum phase to the solar emission before the eclipse was equal to 3.7 and 5.9% for 3.2 and 4.9 cm, respectively.
