How happy birthday is put together
HAPPY is H (four dits), A (a dit and a dah), two Ps (a dit, two dahs and a dit each) and Y (a dah, a dit and two dahs). BIRTHDAY is B (a dah and three dits), I (two dits), R (a dit, a dah and a dit), T (a single dah), H, D (a dah and two dits), A and Y. That adds up to 41 marks, 25 of them dits.
At 10 words per minute (WPM), the speed the player starts at, the whole greeting takes about 17 seconds. The two Ps of HAPPY sit side by side, and only the three units of silence between them keep them apart.
No shortcut on the air
Radio operators shorten most greetings. The International Amateur Radio Union’s operating guide lists HNY for Happy New Year and MX for Merry Christmas, but it has no entry for happy birthday. To send one, spell it out as the player does above.
