By the same token, 106.7 would be problematic for a proposed 2LM FM service due to Nova being next door.
Other alternate frequencies for 2LM that would be ideal, but is problematic due to potential adjacent-channel issues, is 97.5, which is in-between 97.3 from Brisbane & JJJ from Gold Coast.
99.1 would probably be the best frequency, where it not for the 1kW-powered SBS Radio service in Lismore itself (ie. not transmitting from Mt Nardi) that operates on 98.9. Otherwise, it’s far enough from Rebel’s 99.4 service in Mt Tamborine (in terms of frequency spacing) & RN’s 99.5 service from Coffs Harbour (in terms of distance + frequency spacing).
