This transmitter covers the southport, Ormskirk and Sefton areas.   A 1.5GHz microwave link is used to feed the site from the Southport studios with an sbs radio link for backup. A Guardian performs the audio switching. The standard sbs configuration of MaXiM and MPX5 are used, with FMLP2 exciters, PA250 amplifiers and an ACU3 changeover unit. An RE532 RDS unit generates the RDS and can be updated from the studio if required. The transmitter is housed in a cabin supplied and installed by sbs. A guyed mast was erected to support the cardioid transmit antenna, 1.5GHz panel and 450 MHz colinear antenna.  At the studio, a Sound Style processor was installed.
