ATMOSPHERIC RADIO NOISE DATA BANGKOK, THAILAND, JUNE-AUGUST 1967

Abstract

Measurements of atmospheric radio noise are being made by the Electronics Laboratory of the Military Research and Development Center (MRDC-EL) , a joint Thailand-United States-organization in Bangkok. Information about the site and the equipment is given. Four frequencies, either in the MF and HF bands or in the VLF and LF bands, may be recorded simultaneously for 30 minutes. Switching between the two sets of four frequencies is accomplished automatically each half hour. The average power and the mean envelope voltage are recorded on an 8-channel strip-chart recorder. The thirty-minute samples are taken as representing the noise condition for the full hour.
