I’ve use GPS in the past with my SDS200 while traveling the I-95 corridor from Ct. to Fla. and watch the scanner update itself when necessary. So, I know GPS works. But then I saw another menu option called “Use Location Control” and wondered if that feature would be advantageous while traveling locally. First, my understanding of “Use Location Control” is when the scanner is receiving a trunked system with many sites… thinking the scanner is looking for all sites (when none are Avoided) and simply skipping over those outlying sites that aren’t strong enough to be heard? This assumption on my part is probably wrong. But I turned on the “Use Location Control” and un-avoided all that may have been avoided within that trunked system. (Interesting to note that those avoided still show as being avoided, even after I asked for them to not be avoided using the global command to stop avoiding.) Can someone please explain what “Use Location Control” does? And why the global “Stop Avoiding” does not do what I thought it’s supposed to do?
