Only radios with a transmitter will have an integrated antenna tuner. Some radios, such as the FLEX-6300, have the antenna tuner as an option. Each individual receiver may have different antenna specifications and may have different tuning ranges.

Start the antenna tuner to find an antenna match. Note that there must be a slice designated as the transmitter and the radio transmit state must be READY. READY indicates that the radio can transmit on the selected frequency. <pre> C[D]<seq_number>|atu start </pre> Example: <pre>C14|atu start</pre>
