For builders. From idea to RF.

Build your radio system.
One module at a time.

Start with a kit or module, then add the parts your project needs. Explore four building blocks for assembling or upgrading your radio equipment.

AN EXAMPLE FM SIGNAL CHAIN
01
Audio → stereo encoder
Combine left and right audio into MPX
02
FM exciter
Generate the radio-frequency signal
03
Amplifier + filter → antenna
Add RF power and suitable filtering

The diagram shows one possible FM setup. An exciter with built-in stereo encoding may not need a separate encoder. An STL is a separate link between studio and transmitter locations.

Four building blocks. Four different jobs.

01

FM exciter kits

An exciter generates the FM radio signal. Choose it around your frequency, audio input and required output power. Depending on the model, you may need a display, controls, power supply, cooling and enclosure. Some exciters already include stereo encoding.

02

Stereo encoders

A stereo encoder combines left and right audio into the composite MPX signal accepted by a compatible FM exciter. It suits a separate audio-to-MPX stage. Check the input levels, output connection, supply and any optional display or RDS equipment.

03

STLMAX link modules

A studio-to-transmitter link carries programme audio between two locations. Build it around a matching transmitter and receiver, with suitable antennas, cables and supplies. Confirm the frequency and audio configuration at both ends.

04

FM amplifier pallets

A pallet increases the power of an RF signal supplied by an exciter. It needs correctly matched drive, a suitable supply, heatsink and cooling, output filtering and protection. Choose these together for the exact model and operating frequency.

Plan the complete build before ordering

Tell us which module interests you, the operating frequency, desired output power and what equipment you already have. We can help check the required supply, cooling, filters, controls and connections. A kit may be an assembled board or a different package: check the exact listing for what is included.
