I am a brand new police scanner enthusiast and looking to get one of the best on the market. Looks like this might be the SDS100? Question is when I go to purchase it asks me 20 questions about what I want to add, 1 or more counties, various antennas and pgms? I just want to purchase it, turn it on, set my zip code and listen to all police, fire, traffic that my area has to offer? Will this happen or do I have to pay an extra $1k in additional accessories and equip to make this happen?
