Hi, I am new to this forum. I have done alot of reading and am enjoying it. I use a BC898T and a recetly aquired BCD 996T. About 2 years ago Medicine Hat City Police voulentarily changed to the ACPO 25 system. Not sure if it's encrypted. Their fequency is 866.5500 . I cannot seem to find any info on their system anywhere I have looked. All I get is a high pitch squeal when they transmit. Tried tweaking the scanner, can't get any voice. I was hopping their would be some type of comm. map table somewhere or something to set me in the right direction. I would appreciate any advice or info .... thanks in adavce.
