Again this is provided with no context, was the tow plane in distress for some reason (partial power loss etc.). How do you know he was not on CTAF? How do you know your radio was working properly (wrong frequency selected, wrong radio-set selected out, your volume turned down). Were you on a straight in approach?
The old patronising tone eh, try to be civil. That particular aerodrome is certified and has an AFRU, we were in touch with other aircraft on the same frequency and no, we were not doing a straight in approach. The tug was no comms and cut in front of us on short final. Had they been using the radio and we were aware they were in the circuit I would have been happy to let them go No 1 but they had chosen not to use the radio at a certified aerodrome so we had no way of knowing thier position or intentions. This was not at YBEV, it was at another aerodrome. YBEV ops are always very professional, give you a heads up on glider traffic when you do the inbound call and now there is no confusion about the frequencies that there was in the days of Perth Centre.
However, a single CTAF that included Northam, York, Beverley and White Gum would be safer than having the current "venn diagram" overlapping for the 10nm radius of each, with three out of the four having different frequencies.
