  On the new digital Uniden scanners, besides CTCSS, there's a DCS you ca=
n =

set. I assume this is for digital. =

DCS stands for Digital Coded Squelch, it's an alternate version of CTCSS
tone squelch that uses a digital value to open a radio squelch as opposed=

to a sub-audible tone. It is used with analog radios, not digital. Digita=

radios use what's called a NAC or Network Access Code. The NAC function i=

not available on scanners...

Since all my Justice/Treasury is now P-25 =

digital, and alot of these freqs have a tone or carrier on them, does
anyone =

know which (if any) DCS can be set to block out carriers, Mexicans,etc.? =

<<<

I guess you can pick whatever you want to block out unwanted traffic.
However, beware that the Radio Shack PRO-96 radio clearly states that if
you assign CTCSS or DCS tone squelch to a channel, it will NOT receive a
digital transmission. I have not seen the Uniden manual if the tone squel=
ch
overrides the digital mode...
