Feasibility Study
F.M. Station near MSU-IIT

I.
DISCRIPTION OF PRODUCT OF SERVICES The Adalla Schools Foundation (Non-Government Organization) is considering on establishing an FM broadcast station near the vicinity of Mindanao State University Iligan Institute of Technology that could operate at an assigned carrier frequency of 105 MHz. With 225V of carrier voltage and load resistance of 100 Ohms, the pilot output power of the FM station would be 250 W, and this will hopefully be improved since the station is funded independently on its early operating years. It is a wideband FM which transmits with up to 75 kHz deviation from the center frequency. This frequency deviation could transmit music, speech and information signal frequency with up to 15 kHz bandwidth (modulation index of 5). Because of its wideband specification, signal-to-noise ratio is improved. Lesser amplitude in demodulated signals means lesser total noise figure that indicates to have better signal.
II.
TECHNOLOGY CONSIDERATIONS. The City of Iligan, is an industrialized city having three private commercial FM broadcasting stations: Real Radio Iligan that operates at 92.7MHz, iFM Iligan DXIX which operates at 102.3MHz, and Wild FM Iligan DXIL at 103.1 MHz. The Philippine broadcast band uses the standard VHF broadcast band which expands 87.5MHz to 108MHz. Having a small output power is a disadvantage for the latter because its competitors use FM technologies with high output power. Wild FM Iligan which is close on the assigned frequency could be a great threat for the station because its significant frequencies might have power high enough to interfere the main modulated signal which will be transmitted to radios of the listeners. This would not ruin the whole system but the listeners might hear some interference.
Radio communication systems of institute security might also affect the signal. This communication systems is a narrowband FM, this could be a minor threat for the signal to be interfered.
III.
PRODUCT/SERVICE MARKETPLACE Mindanao State University – Iligan Institute of Technology is a vastly populated institution with about 1011 employees which includes 490 faculty members, 105 lecturers and 416 staff and with almost 10,000 students. Majority of these numbers lives near the vicinity.
Internet is widely used medium for spreading information, but not all students, faculty or people in the community are accessible with this technology since not everybody has its own smart devices to access the internet. For this matter this idea came out.
The primary aim of this FM station is to cater announcements that came from the university. This might also be a medium for the people to access some news inside the institution. For this reason, the people will have the transparency and knowledge on what is going on inside the university. Since our university doesn’t only hold school related activities but also caters public-based activities as well. The station can also provide people entertainment with prepared programs by the station.
IV.
FINANCIAL PROJECTIONS FM radio stations have a lot of things to consider especially on maintaining expenses. The following are: DJ’s salary, operator, maintenance, water and electricity bill. The station could not immediately get advertisers on its young days of operation but might have better investors on the future especially when the quality of the FM station is improved. The projected expenses are specified on the tables. Expenses

FINDINGS & RECOMMENDATIONS Based on the presented information on this feasibility study, it is not recommended for Adalla Schools Foundation to put a 250W output power FM radio station near the vicinity of MSU-IIT.
For the technology, the presented FM radio transmitter is may be too weak to operate on the vicinity of MSU-IIT due to the following reasons: 1. The power of the FM station is too low to overcome the contender’s radio stations with high powered FM transmitters. 2. There are a lot of factors that might affect the transmission of signals and might be interfered when reach to the receiver, first is the established commercial radio broadcast station and next is the communication systems being used by the institute security (this might have low output power yet the FM station to be established is low powered as well and might be affected minimally).
For the continuity of the operation of station based on its financial instability the following matters were cited: 1. It is difficult to maintain the station since advertisers may not be persuaded on what technologies are being used. 2.
The area of the advertised people might be too small for them to gamble on huge projects.
3. The improvement of the project relies on the future investors since it is firstly invested by a foundation. Means no stable income due to its reliability to donations. It is recommended that the station must have a reliable technology to overcome the powerful radio stations along the city. The operation of the radio station must also be widen for vast number of audiences so that investors and advertisers will have better business using the radio station.
