Officially opened on 22 June 1938, plans surrounding the initial broadcast of 7ZR were forced to be amended due to a cable fault between Tasmania and the mainland.

[2] Prior to Lyon's opening address, Liet-Governor Sir John Evans spoke live from the 7NT studios in Launceston where he was fulfilling a vice-regal engagement.

Since 2021, the national current affairs program AM has originated from the ABC Radio Hobart studios after its presenter Sabra Lane relocated to Tasmania from the mainland.

The longest-serving presenters to have worked at ABC Radio Hobart include Bob Curé OAM,[10] Ric Paterson,[11] Ken Short,[12] Chris Wisbey,[13] Tim Cox,[14] Annie Warburton,[15] Stan Murrowood,[16] Louise Saunders[17] and Ryk Goddard[18] among others.

[11] In 2003, Sir Guy Green named Paterson as Tasmanian of the Year, in part due to his involvement in establishing the ABC's annual Giving Tree appeal.

In November 2022, the ABC found Goddard had breached their editorial standards for accuracy after making inaccurate comments on Breakfast about Gina Rinehart and her father Lang Hancock.

[29] ABC Radio Hobart also operates a low power repeater station covering the Orford and Triabunna area where the AM signal is received poorly.
