with the commencement of the national broadcasting service in 1929, the pmg's department was initially focussed on effecting necessary maintenance to the network of transmitters and studios which they inherited from the former class a licensees. it had been clear for some years that these licences would not be renewed by the government and level of financial compensation was not clear. as a consequence, perhaps with the exception of 4qg (operated by the queensland state government), the facilities saw only a bare minimum of maintenance. while funding for future expansion of the transmission facilities of the nbs was limited (both for replacement of the former class a facilities and establishment of additional nbs services), there was an expectation that this would change and preliminary work to identify new sites and appropriate antenna systems and transmission equipment commenced immediately.
