The station initially broadcast on 380 metres, although the choice of this wavelength led to complaints from members of the public, as due to the limitations of the receiver technology of the time, transmissions led to interference to and by other stations, especially 6BM in Bournemouth and the Hamburg radio station.[3].
Reception of the station for many Irish listeners outside Dublin was problematic, although even at the time of the inception of the station, there were plans for a high-power transmitter to serve the whole country[4]. In 1927 the Cork broadcasting station 6CK was established, which relayed many of 2RN's programmes, as well as contributing programmes to the network.
Initially the station broadcast three hours a night, from 19:30 to 22:30, with only a two hour broadcast on Sunday nights[4].
