@TV-Expert and the reason being is due to the market structures where Bill and Pam have bought shells of stations from Gamble and the other Griffith farming families in the swap for Gympie’s s.39.
The heritage station in all three markets was ‘converted’ to FM via auction of the third commercial licence leaving a gap which became a low cost, easy listening network by the Gambles et al. When they cashed in their chips when Macquarie moved out of their camp and into merging the former DMG and RG assets, the swap happened and Bill swiftly used his 2SM/HD content to fill the licences.
With no ongoing programming destined for the three AM licences, and very low viability for this ‘third’ commercial licence, the only one on AM (no previous local shifts with prev owner), Bill & Pam continued that idea.
