Generally, to take sensitive traffic off of the main dispatch channel so it won't be tied up with all the chatter involved with the stand off.Listening to a stand off in New Hope MN right now, why in these situations does the dispatch move to Tac channel. Thanks, new here. pro106
Not just close call but the FCC database online.It also provides the 'urgent' traffic from the standoff to have a generally clear channel. You don't want the urgent call about the subject pointing a gun out of the window to be covered up by another officer calling in a traffic stop. Although this is much less the case now, the dispatch frequency was often pretty well known while the tac frequencies were somewhat secret and offered some level of privacy.
Back in the days when scanners had few crystal based frequencies to monitor with, this was significant. Now with 'close call' and other technologies, it's pretty easy to find and monitor them, assuming that they're unencrypted.
Can you cite some examples?Many times they're not licensed
The FCC rules give law enforcement agencies the right to use *any* unlicensed frequency in their area for law enforcement operations with no documentation whatsoever. This is one of the reasons why the FCC database isn't always as reliable as this site...Can you cite some examples?
MOST agencies understand that using an unlicensed frequency is just asking for trouble (and not just from the FCC - What happens when the bust of a high profile criminal gets thrown out of court because the defense figured out the agency violated U.S. Code in the process of making the arrest?).
As I asked before, can you provide an example where an agency is legally doing this, or cite the FCC rule you refer to?The FCC rules give law enforcement agencies the right to use *any* unlicensed frequency in their area for law enforcement operations with no documentation whatsoever.
