I am using a Uniden Home Patrol scanner in my vehicle and have downloaded the newest database and put Livermore and Pleasanton PDs talkgroups in two different favorite lists. I am hearing nothing on those talkgroups as programmed. The database seemed to download frequencies for several sites. I do pick up AlCo SO east traffic on their talkgroups. Can anyone shed some light on what I may be doing wrong or if there is another issue? Thanks.
