Custom 1 Watt mono FM transmitter
Behringer Ultramizer DSP-1425P is pictured
The items below are placed in the order
that they used in a radio station
A description of the equipment and cost is available
The equipment used, will produce a high quality signal; while keep cost low. Low power drain was also a consideration in equipment selection.
We are able to power up this set up, minus the cart machines; with a 400 watt inverter for about 18 hours on a single car battery.
Coverage area with antenna at 35 feet above ground was over 12 miles. We used several stock car radios from GM & Ford for our test. We also used a low quality after market Jensen for testing too and got similar results.
The antenna pictured is a custom 1/2 wave balanced dipole; the baun is inside the horizontal pipe. When mounted on a metal mast as pictured; the antenna produces a figure 8 patttern. The large lobe is to the front and a smaller lobe to the rear. SWR is ultra low at 1.1.1.
We feed our antennas with LM-400 or RG8 on older installations; avoid using high loss RG58.
This is a simple set up, used by a micro broadcaster
for outdoor broadcast. A computer could
replace the traditional analog equipment.
Inside the case to the left, is a 1 watt Broadcast Warehouse
FM module. This was B/W's original kit version
Less than $1000 was spent
building this micro radio station
A low power AM radio station would be built
using the same equipment; with exception of
the transmitter and processing.
Technically, up to the point of the transmitter; all radio stations require the same items. From the transmitter to the antenna, depends on your license if required in your country; or the power you wish to use if no license is required.
Of course the studio equipment you choose depends on your budget and how elaborate of a set up you desire.
The equipment above is bare bones for a good sounding radio station.
