Quite contrary.
Divcomm is handling this, not DTI. Although most of the work will be done by contractors with Divcomm supervising the process and interacting with the customer. The templates will be standard, but there is some deviation allowed. At the county chiefs meeting, it was advised each department would be allowed to customize its own zone, and that paperwork from each department was supposed to have been submitted in November I believe, I know ours was.
Word on the street from credible sources indicate that newcastle will be the first county to be programmed with the rebanding template, and that it should begin in 2 months. After that, it will be kent and then sussex.
As for fire radios being recalled, that is not possible since none of them have been programmed yet. Divcomm did have to come around and read the radio template from each department, and many had to be re-read recently due to the contractors wanting more information than was requested the first time.
