I have been advised that my radio use can be too wordy sometimes.
To help cut down on your transmission time, please try to:
* if necessary, drop the clarifying words (eg. "this is")
* know your message before you press your PTT button (message pads for planning complex messages can help greatly)
Apparently, in some circumstances, prowords like "affirmative" and "negative" can be too long. While in other circumstances they can be needed to ensure clarity. Establishing abbreviated versions of longer messages with your teammates can reduce the time it takes you to transmit. Practice together, as confused or garbled messages can be worse.
The more instinctive the 7-line format is, the more naturally you will use it in a game. Practice your formats:
