The Extreme tools don't show how the HP1 works, it shows more (much more) about the Conventional and Trunking radio systems we are monitoring. As an example, the RF power plot lets you set a frequency, then check for best reception location or analyze which of several antennas works best. If you are monitoring a multi site trunked system, using the Trunked System Analyzer -->System Load/Reception Status tool will allow you to see Signal/Quality/Activity on each of the tower sites you are receiving. As a new user, I'd suggest that you do more reading before you spend the $100.00, the tools are intended for advanced users and it pains me to see people complaining that they don't feel the Extreme edition was worth while when the real problem is they didn't have the need for the tool set yet anyway. It kind of reminds me of the Saturday afternoon backyard mechanic who plops down 10 grand for the biggest Craftsman tool set and then doesn't know what the tools are for... :)
