I highly recommend the Uniden SDS100 (or 200) scanner for the LA area. I am actually from there, and visit frequently, so I have all of the LA systems in FLs on my 100 - and San Diego/LaJolla/Escondido area - so I do keep several California systems in my SDS100 and TRX-1. So very reliable and easy to flip systems off and on as I go. The SDS100 is THE scanner for southern California monitoring. I travel with 4 handhelds - my Yaesu FT60R 2m/440 HT, Uniden BC125AT, Whistler TRX-1, and my SDS100. Never leave home without them
To the OP, even tho some agencies are 'going dark' all over the US, there is still so much more to listen to in your locale. If you want a scanner that will keep up with the LA area, you won't be disappointed with the Uniden SDS100.
