What are the best frequencies for an FM transmitter?

The FM broadcast band, used for FM broadcast radio by radio stations, differs between different parts of the world.

In Europe, Australia and Africa, it spans from 88 to 108 megahertz (MHz) - also known as VHF Band II - while in the Americas it ranges from 88 to 108 MHz. The FM broadcast band in Japan uses 76 to 95 MHz. The International Radio and Television Organisation band in Eastern Europe is from 65.8 to 74.0 MHz, although these countries now primarily use the 88 to 108 MHz band, as in the case of Russia. Some other countries have already discontinued the OIRT band and have changed to the 88 to 108 MHz band.

If you want everyone to hear your broadcast, or at least as many people as possible, use the 88–108 MHz band, that's where all the commercially made, personal radio receivers work and all the commercial broadcast radios work.

Based on the rule, we produced TR502 and TR505 with the 88~108MHz frequency.

Let's check the details of TR502/TR505

  • Frequency range: FM:88~108MHz      /  FM:88~108MHz  

  • Frequency step: 100Khz                      / 100Khz

  • Frequency stability: ±10PPM              / ± 10PPM

  • Frequency stabilization method: PLL

  • Harmonics, noise radiation: ≤-50dB  / ≤65dB

  • Output impedance: 50Ω                      / 50Ω

  • Pre-emphasis: 75us

  • Audio distortion: 0.3%                         / 0.3%

  • Bluetooth distance: about 5m

  • Frequency response: 50Hz~15000Hz  / 50Hz~15000Hz

  • Separation: ≥30dB                               / ≥35dB

  • Frequency modulation: ±75KHZ         / ± 75KHz

  • SNR: ≥60 dB                                        / 70 dB

  • Antenna connector type: TNC             / TNC

If you want to broadcast the church’s Easter service to cars in the parking lot, to avoid people meeting together, you can check the Retekess TR502 OR TR505.
