Conventional Talkgroup and Radio Scan Enhancements
A few enhancements have been made to the Conventional Talkgroup at the system. These enhancements
improve the Scan feature operation significantly when multiple agencies are using a single conventional
radio frequency channel. These enhancements allow users to use Selective Squelch to operate on only the
subset of talkgroups that are relevant to the users rather than all talkgroups on the channel. These Scan
improvements have been made to eliminate the audio holes that were present and to turn on the busy LED
when activity is present on the channel. Mixed Vote Scan and Standard Conventional Scan configurations
are supported.
Priority Operation is also supported.
Up to 30 different talkgroups can be supported using conventional channels. A maximum of four talkgroups
can be supported when Vote Scan channels are being used.
Smart PTT is supported with this enhancement as Smart PTT prevents users from transmitting while other
users are on the channel.
Note: User Selectable Talkgroups are not compatible with this Conventional Talkgroup Enhancement.
