Interesting excerpt from a Harris Corp. press release from March 22, 2010.
The new Harris P25IP system will serve more than 80 agencies and 31,000 users throughout the county, including the Miami-Dade Police Department, Miami-Dade Water and Sewer Department, and Miami International Airport. The new system will continue to interoperate with Miami-Dade Fire Rescue's conventional VHF system. The P25IP system will operate in parallel with the county's existing EDACS system, providing a smooth transition for the county's users during the upgrade to the digital system. The Harris customized migration plan allows for the reuse of existing shelters, towers and generators.
Today I spoke two Miami-Dade police officers carrying their new Harris radios. One officer told me that they are NOT working well. All transmissions are delayed and not received in real time, according to them. I am sure that Harris will iron out the bugs in this multi-million dollar system. I suspect that the simulcast of conventional trunking and the total conversion to Harris' encryption capable radios will come in the next year or so. Sad for us scanner folks.
This the trend nationwide for police/fire in many areas.
