Yup I'm using 1.9.7... I'm using Pro-106
Interesting and weird; I just checked here on the Berlin Tower and I am not having that issue. Perhaps you are getting interference from another site or something. Try turning on the ATT function as put the scanner on the center channel for the actual reported control channel and see if you still have the issue. I'll have to test that one myself near a site. Been to three of them and haven't had that issue to-date; but that doesn't mean it doesn't exist either. Are you also running the latest firmware in the Pro-106 which was released earlier this summer? There may have been hidden changes in that too. Both the PSR-500/600 I'm using are running the 2.0 firmware update. Radio Shack's may vary slightly in revision number, but it should include the same updates; one would think...
Anyone else experiencing this issue? I do not have access to a Radio Shack Pro-106 to see if there's a difference or now.
