A while ago I asked "Station near XXX squawking 7600 (radio fail) sqawk ident if you are recieving me." I thought that was fairly clear, but what happened was that 3 other aircraft near XXX took it as an instruction to dial up 7600 and did so. The system beeped dutifully and displayed the symbols for each case.
Exercising the flinch muscle was not a problem as fortunately the mighty Eurocats 2000 (as used in Australia) uses the same beeping noise for every situation that happens 67 times a day as for the alert above, so we are thoroughly de-sensitised to such alerts, and barely bother to look when the conflict alert goes off.
