MRTI with a TRBO repeater (Kind of Long Sorry)
Posted: Thu Jul 17, 2008 6:31 pm
Hello All
I was presented with a problem on Monday one of our local police departments UHF repeater was hit by lightning and the department is in need of some new equipment. This department uses their repeater with a MRTI due to lack of cell coverage and no one at there station to answer the phone.
The old system used Inv/scramblers located in each handheld and in the repeater, to try and provide some means of security.
As we all no its public safety so funding is scarce and they don’t have the funds to go to an ASTRO type system.
I immediately thought of replacing the old system with a new MotoTrbo system due to its “some what secure” digital operation. Upon further research I was told by Motorola that the acc connector on the back of the repeater would only be active if the repeater were set up in analog mode which defeats the security purpose for going with the TRBO equipment.
My question to anyone who might be able to help me is the TRBO mobiles acc connector the same as in a CDM or Maxtrac 16 pin?? If so do they provide analog Rx and TX audio and a cor and ptt pins. If they do, would I be able to set up 2 TRBO mobiles with a RICK or use a MRTI as a controller and build my on Digital repeater like the old analog GR series? Let’s say to XPR4300s and a RICK??????
My brain say that even if the signal is digital that for my ears to hear it and for someone to say it there has to be digital to analog conversion some where, question is " is it at the Acc connector"
Thanks for any help any one can give me.
