"Hello: I just purchased the ARc500 Scanner Programming Software and the right cabel USB cable and have two problems. First, for some reason I do not think the software is regonizing my Radio Shack Pro-106 because nothing can be read from the scanner (I have paid RadioReference for use of the data base) but I can cut and copy Freq. into the sotware but not into the scanner? Second I click the RR button in the sotware and sign in and it will not show any data? So sure hope someone can help me, but mostly how can I  tell if the ARc500 software is reconizing my scanner. Thank you for any help. Don."
