Not very easily as I do not have any way to power it in my vehicle. I am line of site with the tower at the 911 center and can physically see all the antennas on the tower. That's why I know this is probably not a poor signal issue. I am going to continue to tinker with the those P25 settings and see how that goes. I've never had one of these scanners give me this much trouble!Is there any way for you to take it somewhere closer to the transmitter temporarily to test it out?
