I have had scanners just about all my life. But; I am lost when it comes to this digital stuff. Can anyone give me a newbie's understanding of this side of scanning? All the stuff about talkgroups, programming via your computer. Hmmm I am not stupid but .... Also; I live in VA where I have APCO25 system for Fairfax County, Montgomery County all use this Motorola Project 25 trunked system for all public safety communications and DC uses an ASTRO Trunking System. Most talkgroups on this system are P25 digital. So; if I buy a scanner that says it's APCO25 will it work for this P25 and so on? I am really looking forward to getting back into the world of scanning so any info is appreciated.
