Looks like RTÉ are about to do DRM :-)

RTÉ have a notice up on Aertel (this one) saying that 252 kHz will be off air from 09.00 on 26/03/07 until 18.00 on 30/03/07.
"Network requires this outage for the transmitter replacement project. At the end of this outage the new transmitter will be operational".

Yay!
