currently scanning pbso in florida and often I hear scrambling need help

SCANNING palm beach county, florida sheriffs department

sometimes I hear scrambling of conversion on my bc250d. I have the apco25 card installed. Is there anyway to decode these scrambled speech broadcasts? I had a radio in the past that had a speech descrambler board that worked with the old wireless motorola telephones and am wondering if this can be done with these digital conversations.

Thanks
