Bloggsie, I don't recall that group getting involved at that level, tho' they may have. I recall that the talkfest started around the same time, but not directly related to those higher up the 'tree' that were tasked with setting the big picture. There was a time when talking was seen as 'protection' against a MAC especially in the circuit when in fact it did nothing or very little to improve circuit safety. It has now been recognised that only certain key calls are needed on the CTAF/MULTICOM which can be used to facilitate appropriate separation. This is all the more important when using 126.7 as other locations may be in range and share the conversation/s. The menu of calls should be recommended depending on circumstances and not specific or mandatory. The task now is to spread that word - we don't need to know what the other pilot had for breakfast!!
