I am still a bit confused about the agreement to swap 3YB and RPH.
It was mentioned that 3YB FM on 94.5 will have the same coverage as Coast FM (95.3) currently has but looking at the ACMA handbook it looks like Coast FM is licensed for 20kw ERP whereas the former 3RPH was only 5kw.
3RPH 94.5 Community M DA 5k -38 18 17 142 44 15 1157809
3YFM 95.3 Commercial M DA 20k -38 18 17 142 44 15 10093184
Does the power output now change for 94.5?
Also for those playing along at home, here is the former 3YB entry from the handbook. Only 2kw but obviously AM radio has different ERP coverage characteristics when compared with FM.
3YB 882 Commercial V DA 2k -38 14 26 142 36 49 10266290
This was taken from the April 2018 handbook, no doubt an updated version will have the call signs swapped for 882 and 94.5.
