The active region HR 16898 has been observed in optical, microwave, ultraviolet, and soft X-ray emission. Emission mechanisms are identified for each radio component by comparing the radio intensity and polarization distributions within the ultraviolet and the soft X-ray intensity distributions. The height of the radio sources and the magnetic field strength at that height are deduced. The radio source above the large leading spot of AR 2502 is due to thermal gyroresonance emission from the second and third harmonic layers. The extended looplike structures connecting the leading and the following part of AR 2502 is due to the thermal free-free emission by hot and dense plasma. A warm radio component found above the L spot seems to be due to optically thick gyroresonance emission by high density and low temperature matter. Two indications for a nonthermal source were found: one is the strong emission associated with the magnetic flux inflow, and the other is the bright following part of AR 2502.
