Tx Steering

 Enables the transmit (Tx) frequencies of each Scan List Member to vary in a Voting Scan System (see the Scan Type field, "Voting Scan" selection).

 When disabled, it is assumed that all repeaters on the Voting Scan System receive on the same frequency, thus all Tx frequencies must be equal.

When the Scan Type field is set to "Voting Scan", and

when the radio is model / option capable.
