I Just know the basics and need sum help with Knox co's radio system,Does anybody know the CTCSS and/or DCS codes of the Knox Co Sheriffs dispatch both A&B and KPD's A,B,and C dispatches? I've programmed all the trunked channels on my Pro-97 but i cant seem to get it where it'll single on one talkgroup so i just hear all talk groups mostly the KAT buses even after i've locked those out, arent the DCS and CTCSS codes for hearing one specific talk group?

You don't use DCS or CTCSS when monitoring a trunk system. If you have all ID's programmed into you scanner, you will want to run the Pro 97 in Closed Mode. When you are in this mode, it will only let audio through on the ID's that you do not have locked out.

You currently have you scanner running in Open Mode which allows ALL talkgroups to be monitored, even if you have them locked out.

Correct, Squelch codes are for conventional analog systems. You do not use them on trunked radio systems. Program in the control Chans.. Program in the talkgroups you want to hear. Scan in closed mode.
