Brisbane has one DAB+ on channel relay which is either not operating or at a very low wattage.
It is also high on a ridge in the west of what was Caboolture Shire. It has the potential if operating at spec of the weaker OCR signal confusing radios on the other side of Brisbane where signal may be close to equal to the Mt Coot-tha output (as the Mt Coot-tha output, engineered in a pre ATV shut down, pre restack era is too low).
ACMA mentioned these concerns in the 2016 consultation documents (of which we are still waiting to be finalised and implemented by broadcasters).
CRA installed it as they were hoping for extended coverage, “fortuitously” outside of the Brisbane RA1 into the Sunshine Coast and that the one OCR would cover the weaker signal areas of the Moreton Bay council region where the limited signal from Mt Coot-tha due to pre restack limitations impacts reception.
