Hey, I am trying to program a ws1010 Whistler for my grandpa. I am trying to get channels from Chicago and Lake county Indiana, I programmed some frequencies from radio reference, however, when I go into scan mode, I never hear anything from the PD and fire channels I programmed. I have the volume set on the max setting, and the squelch set at the 12 o'clock position. I am very very new to this so please try to explain some trouble shooting methods in the lamest terms. Thank you for your help in advance!
