Listen before you speak. Is the channel clear? Think about what you are hearing.
If you have time, write out your message before pressing the PTT button.??
Use the 5-second rule. Speak for five seconds max. If you can¡¯t say it in 5 seconds say ¡°Break¡± and pause a few seconds to listen for anyone else and then continue again with call sign.?
Wait for a response to your call. Unless it is a life-threatening emergency, wait for 10 or 15 seconds or so before you call again. The person you are calling may have heard you but is dealing with other distractions.
Acknowledge a call out to you ASAP.
Use plain English; avoid jargon and abbreviations, 10-codes
Do not provide personal info on air (no victim names, etc).
Speak at a rate that allows the writer to keep up.
