Abstract :
Radio Refractivity and frequency modulated
radio signal strength were simultaneously synchronized
through a self-developed frequency modulated radio
signal Strength (FMRSS) and radio refractivity (RF)
Meter to acquire data for this research work. The meter
was tuned to Osun State Broadcasting Cooperation
(OSBC) at FM 104.5 MHz to acquire data over period of
66 days from 23/11/2021 to 05/12/2021, 17/12/2021to
31/12/2021 and 01/01/2022 to 05/02/2022 respectively. The
data were processed and the result viewed to infer the
relationship between radio refractivity and frequency
modulated radio signal strength.. Critical overview of all
curves of the analysis reflects the same result that
frequency modulated radio signal strength varied
inversely to radio refractivity. That is, at a rising point of
radio refractivity, frequency modulated radio signal
strength is observed falling. Though mostly the two may
have the same variation trend-lines direction, it is clearly
featured in nearly all the analysis figures that a fall in
radio refractivity increases the strength of OSBC
frequency modulated radio signal at any point of
reception during broadcasting operation. Therefore, a
good reception of frequency modulated radio signal
strength (FMRSS) is always achievable when all
climatological parameters are at the normal states of
favorable weather condition of moderate pressure,
relative humidity and a fairly high temperature where
radio refractivity will be at a low level for an improved
frequency modulated radio signal strength in
broadcasting operation. This has recommended a
reasonable determination of frequency modulated radio
broadcasting station site location with stronger
transmitting equipment (transmitter and antenna) and
appropriate antenna height positioning, that will favor
low radio refractivity and strong frequency modulated
radio signal strength.
