6. TX Preamble Duration (ms)
Preamble is a string of bits added in front of a data message or control message (Text Messaging,
Location Messaging, Registration, Radio Check, Private Call, etc...) before transmission. This
preamble prolongs the message in order to reduce the chances of the message being missed by the
receiving radio. The Transmit (TX) Preamble Duration sets the duration of the preamble. This
duration needs to be increased as the number of scan members increases on the target radio. This
value can be increased in all the transmitting radios if scanning radios are often missing data
messages. However, a larger preamble occupies the channel longer. Therefore, increasing the
Transmit Preamble duration will increase the success rate of data received while other radios are
scanning, but will decrease the amount of data that can be transmitted on the channel. Range
Maximum 8640 ms
