It sweeps over the range of 1.075 to 13.825 MHz with as many as 256 channels. However, some of the time the number of channels is restricted to 16 or 32 so that direction of arrival and polarization information can be obtained. Radio receiver band 1 (RAD1) is the low frequency radio astronomy receiver. It sweeps over the range of 20 to 1040 kHz with as  many as 256 channels. However, some of the time the number of channels is restricted to 16 or 32 so that direction of arrival and polarization information  can be obtained. The overall frequency range is 4 - 256 kHz.
