Do you want to get started with scanning or brush up on basics in the new year?
In this episode, Phil goes through a rapid-fire rundown of trunking and trunked systems.
This is part 2 of this 2021 crash course.
What You Will Learn in This Week's Podcast:
- Trunking means that multiple users share pooled frequencies, allocated on an as-needed basis.
- Each talk group is assigned a frequency to use, which is more efficient than conventional systems.
- These systems can be linked together into networks.
- The control channel can be considered air traffic control or the traffic cop at an intersection; when a user keys in they request a voice channel, and when it’s no longer in use, everyone moves back to the control channel.
- Types of trunking include EDACS, Motorola Type II, P25, DMR, LTR, NXDN, and more.
- Rebanding came about because NexTel purchased ESMR frequencies, which resulted in cell phone band frequencies moving up 15MHz and public safety bands moving down 15MHz.
- Simulcast is when you have multiple transmitter locations keying up at the same time and broadcasting the same information over the same frequencies.
