Richmond Scanning

Greetings. I have noticed that lately I have been having a problem with hearing the Richmond system on both my 396 and 996 scanners. In scan, it will hit on what I think is the data channel but it will not not lock on the frequency and quickly jumps back to scanning. Hitting hold and scrolling through the frequencies will produce ho data signal. I have noticed this in the last 2 months when I have been up there. It was fine before then. I have checked and rechecked that I have the correct frequencies and type of system, which I do. I am having no problem with Henrico. Has anyone else had a similar problem or am I just lucky? If so, is there a fix? Thanks in advance for any info.
