FM transmitter kits

Please scroll down to select and purchase our FM exciters!

One of the first steps when building your own FM transmitter from modules will be the choice of exciter module. Below are a few typical scenarios that will help you decide. If you are lost and don’t know where to start consider reading this guide for setting up drive in cinema FM radio written by PCS Electronics. In contains interesting information to help you get started and will be valuable also for other situations. Typically scenarios in the field:

Small community stations in remote areas, far from urban centers or critical infrastructure, with limited budget.
STMAX3015+ (STMAX9015) or STMAX3015 micro work best for these since they come with built-in stereo encoder and RDS. This reduces both cost and complexity. It can also be easily programmed via LCD without the need for PC to set the RDS parameters. Audio quality is pretty good. Spurious level is not suitable for professional setups as integrated digital modulator creates some in-band artefacts about -50dBc down. If you’re looking for a simple solution where those issues are not a factor (remote rural area) do get one of these, you will not be disappointed.

Small and large stations that require compliance with standards and high signal purity
MAXPRO8015+ works best. You will also need a separate SE8000 DSP+ stereo encoder or Audio processor with MPX output. It is equipped with DIGIAMP interface and also supports MAXLINK II so when interfacing with SE8000 or amplifier you practically don’t need to solder at all. Any of these can drive any amplifier up to 10KW and more. Used in our high quality CE certified CyberMaxFM+ SE+ and BE+ series.
