326 - SRU105 - Analog and Digital Trunked Systems

Once upon a time, we only had analog trunked radio systems. These systems all had analog voice talk groups. These systems included Motorola Type I, Motorola Type IIi, Motorola Type II, EDACS, and LTR systems. Today, we are living in a digital trunked environment, where there are no analog voice channels. All voice is done using a form of digital modulation. These systems include P25, DMR, and NXDN. But, we had an in between. This is where we had digital talk groups on an analog trunked system. On a Motorola Type II system, we could find P25 talk groups. On EDACS systems, we'd find ProVoice talk groups. This podcast will discuss analog and digital systems, and explain why our older P25 scanners like a Uniden BC785D will not work on today's P25 Trunked systems. ==================================== 🛒 Check out our new Merch! ==================================== Squelchy opened his own store selling Scanner School merchandise!
