Divosh, over use of radio in the bush would be as worse as none at all. If there is no traffic in the area why make (Apart from if you like the sound of your own voice) 8 calls from inbound to clear? Or if there are 2 or 3 Aircraft doing circuits all calling on all legs of the circuit, you can't get a word in and you can't tell me their "Doing the right thing".
For those more familiar with AIP's, what are the "Required" calls?, not "Recommended", there is a difference.
