Suitability
This transmitter is perfect and ideal for large campus, college, type radio. Also for Hospital type radio with large grounds. Special events like carnivals etc. that need maybe 1 to 5 miles range will find this transmitter the right size.
Stereo with Audio Processing Option
This is the most popular version because it includes everything in one enclosure. The audio processing keeps the audio level 'LOUD', but not too loud whereby it causes over deviation and contravenes your permit. The trick is to get the sound as loud as possible so you can compete with the other stations on the dial, but at the same time keeping your signal legal. This is a tricky balance to maintain, but this version in stereo with our internal audio processers does exactly this. More Information HERE.
RDS Option
As an optional extra this transmitter is available with dynamic and programable RDS fitted. If you want RDS option please (rds-upgrade) ADD TO CART
Antennas
On delivery the equipment is ready to plug in and use with any suitable 50 ohm antenna system such as our:
• SINGLE DIPOLE
• 4.8dBi 2 DIPOLES
• 7.8dBi 4 DIPOLES
• 10.8dBi 8 DIPOLES
• 4.8dBi 5/8 ANTENNA
• -0.8dBi CIRC. DIPOLE
• FOLDED DIPOLE
Our system package the 10W EIRP system includes this transmitter with a dipole antenna and very low loss LMR400 cable to give you a full system that will comply with the regulations of the European Union and most other countries in the world.

Reliability
The power transistor used in the output stage is rated at 15 watts minimum, basically it's over engineered. This is the difference between our transmitters and the Chinese transmitters. The Chinese use semiconductors that are just enough and no more. This is okay until there is an accidental antenna fault, which happens frequently, and the Chinese is one is toast !!. In the meantime, our transmitter continues happily without damage.
Construction
The enclosure is made in strong 16 gauge steel, powder coated and baked in satin black. This leaves a tough, durable surface that will never rot or corrode and be cleaned to shine for decades. The front panel is 19 inch across and 2U (3.5 inch) high with a depth of 12 inches, so it will fit with ease into a standard rack. It is very strong and difficult to damage even under extreme handling.
Settings
If you are qualified or understand broadcast radio specifications and parameters you can set the frequency and deviation yourself. This is easily done by flipping over the unit and adjusting the little dip switches on the underside panel. More information on this in the User Manual, you can find a link to this below.
Compliance
The stereo version with audio processing and limiting meets all the regulatory standards required out of the box and pre configured. In fact if you send us a copy of your permit and it's conditions, we will set it up exactly to the specification. This equipment complies with EU/CE harmonised standards and FCC technical requirements for FM broadcasting. More information HERE
