Maybe someone who knows about FM radio transmission equipment can help me. I'm the pastor of a 200 member church in Berlin Germany. I would like to build a small system to broadcast simultaneous translation. I would think all I need is an FM transmitter, microphone and FM radios or headset receivers. The maximum distance required is 75 feet. Is there something I'm missing? Can anyone recommend the kind of equipment I need to purchase? I've seen systems for 10 people at $1000 but I would think I could reduce that price by half or more with a DIY system. Thanks for your help.
