Transmission System

Revival Radio operates a system where our transmitter location is remote from the studio complex.

Audio from the broadcast studio is first sent to our Behringer audio processer which optimises the audio output levels ensuring our signal has maximum "punch".

The processed audio is then fed into our SBS link transmitter where limiting circuitry ensures that the audio applied to the transmitter is contained within specified technical perameters. The output from the link transmitter is then beamed to our transmitter location in the Kilsyth Hills.

The main transmitter location is a shared, purpose built, communications facility with a triangular lattice mast on which we have two aerials. The first aerials receives the output from out link transmitter and transfers it to the link receiver in the equipment room.

Audio from the link receiver is taken and passed through an RDS (radio data system) unit which applies the identity of "REVIVAL" which appears on some car radios and home stereo units (see more about RDS below).

From the RDS unit the composite audio and RDS signal is then taken to our Radica exciter unit - this is a 5 watt transmitter (set to operate at 2 watts output) which is set to work at the allocated frequency for the broadcast. The RF (radio frequency) output from the exciter unit is then fed to a Radica 50 watt amplifier. RF Output from the RF amplifier is set to a level which will provide our licenced output power (typically 10 or 15 watts) and is then fed to the second aerial on the mast which is a professional quality, vertically polarised, folded dipole. It is the signal being tranmsitted from this aerial which delivers the broadcast you hear on you car or home radios.

For a full-time Community Radio Licence we will be planning technical enhancements to our transmission system and it's ancilliary equipment. Some of enhancements will be essential to meet licence requirements, while others will be to ensure the continued quality of broadcast service to our listeners.
