CADS, also known as the Wireless Public Address System (WPAS) in the Republic of Ireland. Church Radio re-broadcast service, AM and FM modes allowed, using CB-type equipment and frequency bands.

Three "bands" in (legal) use, the regular CB band 26.965-27.405 MHz, the UK FM "27/81" band 27.60125-27.99125 MHz and the "UW band" 27.605-27.995 MHz. Church services have been heard outside these band limits, often in the 27.405 MHz to 27.600 MHz portion and below 26.965 MHz (CB channel 1). Some churches use modified "export radios" which, instead of observing the UK FM offset, transmit on the "zeros" instead (i.e., operating on 27.800 MHz instead of 27.80125 MHz). Since the difference between UK FM offset and the zero offset is only 1.25 kHz and FM is used, this usually makes very little to no difference to the (local) receivers the church transmission is meant for.
