Q2 has been exceptionally busy for our DAB trial.
The pace has really picked up with the trial now carrying twice the services we had at launch. In addition to All 80s, Pure Classic, Raidio Ri-Ra, Sunshine Radio and UCB we have just been joined by UK based Amazing Radio. This is a mile-stone for Irish radio as Amazing is the first UK licenced station to broadcast terrestrially in the Republic of Ireland. Our feeling is they won’t be the last.
One thing we learned while adding new services is that new mux configurations, once again, show up deficiencies with many receivers. Some receivers update and add new services automatically as one would imagine. However not all do. Some require a listener to re-scan their radio. Two receivers in particular needed a full factory re-set. While we work with receiver and chip manufacturers to fix issues such as this it is good to know these limitations. We shall use this knowledge with particular attention to how we reconfigure the mux in addition to adding a “re-scan” message on DLS to alert listeners of changes.
Also during Q2 we carried out extensive audio tests. We operated two DAB+ channels carrying the same audio but with different settings. Listeners were asked to respond on our website with their observations. What surprised us was the amount of listeners who rated both channels as being equal in quality despite a difference of up to 32k. This strengthens observations, made elsewhere in Europe, that once the audio is acceptable quality the majority of listeners are happy.
On conclusion of our audio tests, our feeling is that DAB+ offers excellent quality at half the bit-rate of traditional DAB. This bodes well for the future as it further reduces costs for broadcasters and increases the choice of stations available to listeners.
Finally, we are pleased to say, our trial licence has been renewed by ComReg and firm orders have been placed for transmission and antenna equipment needed for our expansion to Cork. It’s going to be a busy summer!
