Digital modes, like P25, NXDN, DMR and others will use FDMA, TDMA, or both allow multiple transmissions to share a single frequency at the same time. FDMA or Frequency Division Multiple Access divides a current carrier frequency into multiple parts, allowing for multiple users to operate on the same time on the same frequency. TDMA or Time Division Multiple Access divides a current transmission over time, allowing for 2 or more users to share a the same frequency at the same time, depending...

The Nextel Conundrum: Originally established as a convenient communication solution for small businesses, Nextel swiftly expanded its services to include cellular telephony.    However, the positioning of Nextel within the RF spectrum, sandwiched besides public safety frequencies, combined with its network built for capacity, led to unprecedented challenges.    The dense clustering of Nextel sites interfered with public safety radios, prompting the necessity for rebanding. Rebanding...

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...

  There are two distinct flavors of trunked radio systems that we need to be aware of when programming our scanners.

Systems that require every frequency be programmed into our scanners in their designated sequence are Logical Channel Numbered systems and include EDACS, LTR, and all flavors of DMR. Control channel only systems only require the...
