SRS-10 -- a complete, self-contained radio transmitter providing 10 watts (10,000 mW) of frequency stabilized FM radio signal. It is used alone or with an amplifier. It is easy to use and was designed for operation by people new to radio. Features include built-in sound processing, harmonic filtering, output transistor protection, overheating protection, and it conforms to, or exceeds, the standards of all known national broadcast rules. It is an excellent choice for community radio stations. A mixing board is not required since it can be directly connected with audio sources from a variety of devices such as a tape recorder, CD player or computer and one standard microphone. It can be powered by 12 Volts DC from a battery, automobile, solar, wind or water power system, or from a universal AC adapter plugged into wall outlet. When connected to a sufficiently high antenna its built-in 10 Watt output signal transmits over a 5-10 Km (3-6 miles) range allowing the signal to reach people over a 20-75 sq Km (10-25 sq mile) area. A Stereo Encoder is available as an option.
FRA-150 -- a FM Radio Amplifier providing 150 Watts of radio signal. The FRA-150 is designed receive the SRS-10 output signal as its input signal. The FRA-150 has built-in overheat protection and a fault tolerant design. The FRA-150 can be used in off-grid applications where 24 or 28 Volts DC power is available including solar, wind, water power or two 12VDC automobile batteries connected in series.. When connected to a sufficiently high, properly constructed and connected FM antenna its output signal can transmit over a 60-120 Km (30-60 miles) range allowing the signal to reach people over a 1500-10,000 sq Km (700-2500 sq miles) area.
Note: FM signals travel line-of-sight. This means they will be blocked by hills and not reach into deep valleys. Also the height, design and quality of the broadcast antenna has a significant influence on signal range.
