"QDM 050 Class B G-ABCD"
Notes:
1. The initial "QDM QDM" was a tip given to me by the chap who did my R/T exam, whose day job is as an ATCO. It gives the guy on the other end an early warning to flick the switch on the DF equipment that makes it read the reciprocal bearing you want rather than his bearing to you from the ground station, which it's more likely to be set to.
2. No need for initial call, pass your message & all that. Just pop onto the frequency, get the bearing, read it back, you're done.
3. Class B means 5 degrees accuracy & is probably the best you'll ever hear. Class C means 10 and Class D means he's pulled the number out of his a**!
