Does the Whistler WS1065 have a faster scan speed than the SDS200? My SDS is hooked to a Radio Shack Discone antenna and my Whistler is just connected to an outside mobile magnet mount Tram. What I don't understand, is why the Whistler almost always stops on a frequency faster than my Uniden. The Uniden is usually at least 2 words behind the Whistler when they both stop on the same frequency? It doesn't matter if it's analog or digital. Thanks!
