SBPD going silent at night???

I've been thinking something is wrong with my PSR-800 at night time, but am really thinking something is up with SBPD at night. My scanner does not pull in any SBPD after around 10pm local time. The RR feed for the area seems to be missing out on SBPD in the late evenings/early morning as well. The PSR-800 is pulling in StJoe PD and Mishawaka just fine. Anyone else noticing the same thing??? Any insight is greatly appreciated.
