They will not send, or may send incorrect, position reports after 6 April 2019 unless action is taken:

The following Motorola Solutions TETRA devices need to be updated to set the GPS week cycle number to “2” before 6 April 2019. Impact on Motorola Solutions TETRA radios Our older TETRA radios have a programmable field to tell the GPS chip which week cycle we are in.

Although this affects all electronics that use GPS chips, the lifecycle of two-way radio products is long and they are frequently used with GPS, so two-way radio customers may be disproportionately impacted. Older GPS chips are not able to tell the difference between week cycles and so may run into problems after 6 April. Our latest TETRA radios use these modern chips. Modern GPS chip designers have put software into their receivers that take this rollover into account, and will compare the week number with external sources to work out the true date. This happened for the first time on and is due to happen again on. Every 1024 weeks, this week counter resets to zero. To save repeatedly broadcasting redundant information, GPS satellites send a week number instead of broadcasting the full date.

Please contact your Motorola point of purchase for more information.GPS satellites work by continually broadcasting the time and date. Please refer to Features Summary Chart Section at the end of the user guide for more details. It also provides security by giving the option to set up a password for profile radio's management. CPS is a very useful tool as it can also lock the Front- Panel Radio Programming or restrict any specific radio feature to be changed (to avoid accidentally erasing the preset radio values). To program, connect the RDX Series™ radio via the Drop-in Charger Tray and CPS Programming CableĬPS allows the user to program frequencies, PL/DPL codes, as well as other features such as: Bandwidth Select, Time-out Timer, Power Select, Battery Type Select, Scan List, Call Tones, Scramble, Reverse Burst, etc. CPS Software is available for free as web based downloadable software at: The easiest way to program or change features in your radio is by using the Computer Programming Software (CPS) and the CPS Programming Cable(*).
