Committee on Radio Frequencies

CORF represents the interests of U.S. scientists who use radio frequencies for research—for example, radio astronomers and remote sensing researchers. The committee deals with radio-frequency requirements and interference protection primarily through filing comments under the aegis of the National Academy of Sciences in public proceedings of the Federal Communications Commission. The committee acts as a channel for representing the interests of U.S. scientists in the work of the Scientific Committee on Frequency Allocations For Radio Astronomy and Space Science (IUCAF) of the International Council for Science and in working groups of the Radiocommunication Sector of the International Telecommunication Union (ITU).

Related Items of Interest

Ocean Radar
The audio recordings listed below are demodulated sounds of ocean radars operating in the HF bands. These particular recordings were acquired at a frequency of 4540 kHz. One file was acquired with the receiver in upper sideband mode (filter bandwidth approximately 3 kHz), the other was acquired in AM mode (approximately 12 kHz bandwidth). The overall bandwidth of the transmitted signal was measured to be about 50 kHz.

• Upper sideband mode
• AM mode

Further information on ocean radars can be obtained from the web site of one of the manufacturers (CODAR), at www.codar.com.
