pitadog, I see why you bash GRBT! Spencer, I have owned hisc for a long time, but never have heard whether cybertracker will operate on 450 and/or 800 mhz. These are the frequencies that most schools, municipalities, police and fire depts, as well as contractors, trucking compaines, taxis, etc. Since we "have" sold to these entities, did they put them thru these bands? Reason I ask is my brother owns an FM Radio company in northern Indiana and has 5 towers covering northern Ind and SW Michigan. I have mentioned this to him, but while he has had inquiries from customers in the past, the cost of systems he had seen were too pricy. If the software is included in the 500. price, then he probably can market them. Also, why haven't we set up FM Radio dealers throughout the country? Feel this is another great market to serve. dog http://investorshub.advfn.com/boards/read_msg.aspx?message_id=20419137
