With the crowd I hang around with I use alcohol phonetics like Amaretto, Bourbon, Chianti, etc.
I announce my call as N3 Victor Mike Yankee. When I'm on simplex with the locals I'll say N3 Very Mellow Yellow. On International contacts I'll always use the NATO phonetics. BTW made a 20mtr contact on 2/13 around 0845L to YL2SM in Latvia; 17 & 20mtr bands were open. My only pet peeve, even though it's just hobby radio, is when someone gives their id when required then says "for id".
