Toledo, Ohio recently went to digital and I have been trying desperately to separate the police from the fire.I would like to have the Fire and medical grouped together, that way I can lock out the Police when I feel like it. I have the Radio Shack Pro-2096 using Win96 software to program it. Also if anyone knows of any books or reading material that explains trunking I would appreciate the info. I have read most of the stuff on this site but would like to get more in depth.
