Hello everyone. I have an older Radio Shack Pro -2050 TrunkTracker that's been a great scanner, but recently my local law enforcement has switched to P-25 and when there's radio traffic all I get is static. Now if my scanner is still picking up their signal it seems there should be some kind of filter or add-in decoder chip or some way to get the traffic instead of static, I'm pretty good with electronics, but if there is something to update my scanner I'll also need a schematic for my scanner if anyone has one...Does anyone know of anything to update my scanner? I appreciate any help. Thank you.
