Besides digital scanners what other equipment can be used that is the cheapest ; least has P25 digital capabilities? Would trunking be a issue for the 406-420mhz range? Would one that receives in the 160mhz range be best? Are there any that can monitor comms that would be encrypted on a scanner ? How much do they run?What do you suggest would be the best radio at an affordable price?I reside in the dallas,tx area
