Purbeck Coast FM, which just began broadcasting earlier in 2019 in Dorset, United Kingdom, is going with WorldCast Systems as the supplier for its audio transmission system. WorldCast Systems’ U.K. distributor Baudion managed the project.
Needing a system to link its studios with the transmitter site 4 kilometers away, Purbeck went with WorldCast’s studio-to-transmitter-link codecs, an Ecreso FM 300 W transmitter and an APT IP Silver encoder that was installed at the studio, while an APT IP Silver decoder was put at the transmitter site. The connectivity uses two IP paths, one through a microwave radio link and a second via internet VPN.
Purbeck shares its transmission site with other FM stations, so in order to comply with U.K. regulator Ofcom’s requirements, WorldCast Systems is supplying an additional custom-tuned filter to remove unwanted intermodulation products.
The station is using the Ecreso transmitter’s backup audio players as a program source, which allows the STL codec configuration to be monitored and optimized prior to the commencement of broadcasting from the studios.
