      <Description>The two STEREO radio receivers measure wave intensity, source direction and angular size in the frequency 
	  range 40 kHz to 16 MHz, corresponding to heliocentric source distances of about 1 Rs to 1 AU. One 10-40 kHz 
	  receiver measures radio and plasma waves near the 1 AU electron plasma frequency. One receiver makes high 
	  time resolution measurements at 50 MHz. Time Domain Samplers make simultaneous wideband waveform measurements 
	  on three electric components at 250,000 samples/second. Antenna systems include three mutually orthogonal 6-meter monopoles.
