===== Radio checks =====
Plain language radio checks Whenever an operator is transmitting and uncertain of how good their radio and/or voice signal are, they can use the following procedure words to ask for a signal strength and readability report. This is the modern method of signal reporting that replaced the old 1 to 5 scale reports for the two aspects of a radio signal, and as with the procedure words, are defined in ACP 125(G). The prowords listed below are for use when initiating and answering queries concerning signal strength and readability.
