That's why 135.47 is such a boon now it's here: I suggest you do try & use it correctly for my sake and for other legitimate pilots using our bit of airspace.
Amen to that.
Sadly there are still some legitimate pilots who will not use Safetycom.
We had a group at our strip who resolutely refused to use safetycom on approach despite the recommendation being in our airfield guidelines and agreed by the five other aircraft based there.
Fortunately they have now left and uniformity and common sense now reigns.
