Several years ago I was told a reason for the switch. With digital
encrytion they could not select a site like with analog voice with
CTCSS. So you would have different outputs with the same input so now
when they select a site it is the output channel they are selecting. I
do consider the person who told me that to be an expert in Federal
Monitoring.
I have not heard clear voice on FBI or USMS channels in years except
when the local state-federal Task Force is busy.

The brand new ones in the 170s probably have even wider spacing. I expect they're awash in "Homeland Security" $$$ and don't know what to do with it all. They'll put in all the new repeaters and then still use cellphones instead.
