I just got the SDS100 and have used the Sentinel software to create favorites and continue to have issues with hearing traffic. I get sporadic calls from towns and counties all around me but for some reason I am not picking up any traffic for my local town and county even though I can see it scanning the frequencies for my local Fire/EMS and Police. I have been hunting around YouTube and this is a bit overwhelming, I have never had a scanner before. Thoughts? Thanks
