Field Definitions
Bit Sync Packets Enter the desired value directly or use the UP/DOWN arrow keys to
make your selection. This is the number of synchronization packets
that will be sent during the specified pretime. Each packet takes 46.67
milliseconds to be sent. Therefore, the number of packets will be
adjusted to fit within the pretime duration. The remaining pretime
will be silent. Bit Sync during pretime may be an advantage in some
systems in that it will cause radios receiving the repeated transmission
to DOS Mute sooner.
The default is 0 (that is, no bit sync).
