A frequency modulated radio signal strength
(FMRSS) and radio refractivity (RRF) meter was used to
simultaneously synchronize temperature and frequency
modulated radio signal strength during a broadcasting
station operation. The meter was tuned to Osun State
Broadcasting Cooperation (OSBC) at FM 104.5 MHz for
a total of 66 days, from November 23, 2021 to December
5, 2021, December 17, 2021 to December 31, 2021, and
January 1, 2022 to February 5, 2022. The data were
analyzed to determine the relationship between
temperature and the strengths of frequency modulated
radio signals. The results of the analyses severally indicate
that temperature and frequency modulated radio signal
strength are directly proportional reference time of the
day as equally shown by their variation trend-lines.
