Prosign	Answer or Advice	Example

AR	Used at end of transmission when you are sending it back to the other station. Also used at the end when you answer a CQ.	BTU BOB AR W3BBO DE W2LJ KN W3BBO W3BBO DE W2LJ W2LJ W2LJ AR
SK	Pretty much the same as AR; but to be used only at the END of your last transmission of a QSO.	TNX QSO BOB BT 73 ES GN SK W3BBO DE W2LJ K
BK	Used as a break in a transmission, when you expect the other station to reply quickly without going through station ID.	(W3BBO sends) WHAT RIG U USING? BK (W2LJ replies) RIG HR IS K2
K	Go ahead .... over. Use this when you are turning it over to another station. You also use this at the of a CQ. Do NOT use at the end when you answer a CQ; because you're not sure the CQing station will be coming back to you.	HOW CPY NOW BOB? AR W3BBO DE W2LJ K
KN	Almost the same as K; but used only when you want a specific station AND NO ONE ELSE to come back to you. This can be useful when your in a multi-op roundtable QSO.	W3BBO DE W2LJ KN
CL	Use this only when you intend this to be your last QSO and you will be turning off your equipment. A good way to let other ops know that you will not respond to any further calls.	NICE QSO BOB BT 73 ES GN CUL SK W3BBO DE W2LJ CL
