SPLAT! can use the Longley-Rice path loss and coverage prediction using the Irregular Terrain Model to predict the behaviour and reliability of radio links, and to predict path loss. SRTM filenames refer to the latitude and longitude of the southwest corner of the topographic dataset contained within the file.
The Longley–Rice model (LR) is a radio propagation model: a method for predicting the attenuation of radio signals for a telecommunication link in the frequency range of 40 MHz to 100 GHz. [ 1 ] Longley-Rice is also known as the irregular terrain model (ITM).
FM broadcasting is a method of radio broadcasting that uses frequency modulation (FM) of the radio broadcast carrier wave. Invented in 1933 by American engineer Edwin Armstrong , wide-band FM is used worldwide to transmit high-fidelity sound over broadcast radio . [ 1 ]
In the context of mobile radio communication systems, RF planning is the process of assigning frequencies, transmitter locations and parameters to a wireless communications system to evaluate coverage and capacity. Coverage is the distance at which the RF signal has sufficient strength to sustain a call/data session.
In US broadcasting, service contour (or protected contour) refers to the area in which the Federal Communications Commission (FCC) predicts coverage.. The FCC calculates FM and TV contours based on effective radiated power (ERP) in a given direction, the radial height above average terrain (HAAT) in a given direction, the FCC's propagation curves, and the station's class.

In 1996, UBSI hired former station manager of DZMB and radio consultant Manuelito "Manny" F. Luzon as general manager. Under Luzon's management, he conceptualized a new FM network called Energy FM . It was launched first in Davao , followed by another station in Cebu (later transferred to 89.1 FM from 2003 to 2004) and in Naga.
