800 MHz Radio Update: July 2006 MCFRS IT Training
Overview What, Why, Where and When? How Does the VRS Work? What Happens If You Can’t Reach the VRS? How to Switch between Repeat and Direct Modes? How to Determine When to Use 7-71-72 N Why Not Just Use FDTA and Avoid the Changes? How to Break Down the New Template? Need a Cheat Sheet? How Should You Get Help?
What, Why, Where and When? What: VRS is short for Vehicular Repeater System – we’re installing repeaters in the Batallion Chiefs’ buggies and a few engines in border areas. Why: With a VRS on-site, we can add to existing coverage by bringing a conventional channel to the repeater. Where: The VRS may be used in areas where coverage is weak for portable radios, including near the river and (to some degree) parking garages and other underground structures. When: The VRS won’t be needed very often, but it provides another tool for life safety. Reprogramming runs July 31 – August 14.
How Does the VRS Work? User switches to the VRS Channel
What Happens If You Can’t Reach the VRS? User Switches to Simplex User Switches to Simplex Radio Receives on Simplex by Default User Switches back to Repeat
How to Switch between Repeat and Direct Modes? The concentric ring switch (still the soft-key lock/unlock on every other talkgroup) will enable you to toggle between direct and repeat modes. Concentric Ring Switch Repeat ModeDirect Mode
Why Not Just Use FDTA and Avoid the Changes? While FDTA is a conventional channel, it needed to stay separate from the VRS. A VRS will not always be available (e.g., calls where the BCs don’t respond) Prince George’s County agreed to share the channel that we are using so long as it is only used when a VRS is needed
