This 30W transmitter is a still a worldwide favourite which has been on the market since 1999, it's reliable, it's durable and long lasting, even after 20 years there are various clients in the world still using this model for their community stations. This power level is suitable for a small town.
The stereo version with audio processing and limiting is available or the straight raw composite MPX version. If you're not sure which version you need, then it's a high probability that need the stereo version with audio processing and limiting. In any case the stereo version has the option of MPX input, it can be used for both. If you wish to connect the unit to external processing such as Optimod, Inovonics, Breakaway, StereoTool etc you should use the MPX version More Information HERE.
As an optional extra this transmitter is available with dynamic and programable RDS fitted. If you want RDS option please ADD TO CART above

What is SUPER SILENT? it means it's as quiet as a mouse and can use it in a live mic studio without background noise. Check the video demonstration. If you want SUPER SILENT option, ADD TO CART here.
The output transistor can handle any amount of reflected power comfortably with a a rating of 45 watts on a more than sufficient large heatsink for cooling
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.
This transmitter is fully adjustable by a competent engineer to operate from 87.5 to 108 MHz, in 100 KHz steps, pre-emphasis of 50 or 75uS and adjustable power from 2 to 30W. Like all our transmitters, this is easily done by reconfiguring the dip switches on the under side panel. When we test this we have to set it to some frequency, we prefer it to be the one you choose, so please let us know your frequency.
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
Our system package the 30W 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.
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
