[via media network] Irish public broadcaster RTE carries a notice on its teletext service that the longwave transmitter on 252 kHz will be off the air from 0800 UTC on 26 March to 1700 UTC on 30 March while a new DRM-compatible transmitter is installed at the Summerhill transmitter site. When the new transmitter is installed, some DRM tests will take place at night, probably at 0100-0400 UTC.
