NJT had several systems. Another was their Metrocom transit radio network, which required the driver to press a "Request to Talk" button. The dispatcher would then answer the driver and a channel was granted, like trunking in reverse. I'm not sure what the base side looked like, but their busses had Syntor X9000 800 MHz conventional radios with special outboard controllers that would steer the radios to the proper channel for communication. That was circa 1990.The previous analog 800 MHz Motorola Type I/II TRS was pre-rebanding (utilized the 866 MHz range) and had to re-band at some point. The equipment was old, no longer supported by Motorola, replacement parts were becoming hard to locate, and thus created the perfect opportunity for a transition to digital voice and data. There are myraid opportunities available with digital voice and data versus analog, depending on how the infrastructure is set up and used.
The Hudson Co. senior/disabled vans have been outfitted with the power trunk radios as well. FYI.It cannot be monitored, so impossible to determine. However, I don't believe NJ Transit itself uses it (aside from Light Rail and maintenance operations). I believe it is now used by other Bus carriers such as Academy, Coach USA, perhaps De Camp, etc...
Comes down to old age. Their system was installed back in 1988 and they used micors and msf repeaters. Not stuff you can get parts for these days.there was nothing wrong with that old system why change to digital? Seems like there is so much problems with digital systems now a days it either comes in all broken up or signal lost analog sounds so much better!!
Correct. TETRA replaced the old smartnet system and now carries the buses such as Academy, Coach, Transbridge as well as the other operations within NJT. The main NJT buses still use the Metricom system which is just as old as the smartnet system was. Eventually that will go away and all of NJT will be on TETRA (except the PD, they went 700 NJICS)NJ Transit Buses, at least in northern NJ, are NOT yet on TETRA. I am hearing them right at this moment on their 800 MHz system. (856.2375 - 860.2375) (856.4875-860.4875) in analog mode where they always have been.
