Avoiding Down Time
I'm sorry that no one has replied to your question. I'm a land mobile attorney, representing dozens of M/A-Com licensees in their reband (I was also one of the people that created the Consensus Plan), such as the City of Denver, and in Florida, Manatee County, Hillsborough County, Pasco County, etc.
For the most part, there hasn't been a problem avoiding downtime, but its highly dependent on how much of your system has to be rebanded. A number of "tricks" have been used, from taking down a few of the channels at certain times, to having dual programming in radios, etc.
All of this is highly dependent on the specifics of your situation. It seems to me that almost everyone has done it differently, because it seems like no two systems are identical.
Since the costs are recoverable, there's no reason why you shouldn't retain one of the outside consultants that are experts on M/A-Com systems. Even if you only use them to show you how to do it, you can leverage their knowledge of other systems, and you don't have to pay for it.
For a list of potential engineers, feel free to visit our rebanding web site, http://www.800mhzrebanding.com
, under "resources." We've tried to put everything that we can on rebanding there for you.
