I've had a BC 800XLT under my bed for about 15 years or so. I put it up for sale and questions come back about wether or not it is unblocked. I bought it new and it has never been modified in any way. Can't for the life of me remember what year I bought it. Uniden wasn't very helpful in determining manufacturing year from serial number or wether it is unblocked or not. I'm wondering if someone here can shed a little light so I know what I have and what it might be worth. Thanks!
