Welcome to the Alameda County Public Safety collaboration article, a Trunked Radio System located in Alameda County, California.
This is where you, the user, may index any articles you develop for scanning related topics for this Trunked Radio System.
The ALCO trunked system pools its frequencies into two groups, "Local" and "Wide". This means that not all sites have all frequencies. The sites covering the Tri-Valley area (Walpert Ridge, Sunol Ridge, and Crane Ridge) only have specific frequencies. If you live in this area you will only hear talkgroups assigned to operate on the Wide frequencies. If you attempt to listen to agencies in Western Alameda County, you will not hear them. The scanner will appear to switch to a voice frequency but no audio will be heard. Talkgroups are always assigned full-time Local or Wide status.
You can determine if you will be able to hear all talkgroups on the system by checking the Local frequencies for audio in conventional mode. If you hear nothing, you will be limited the Wide talkgroups only.
Local frequencies: 851.1000, 852.5875, 852.7500, 852.7875, 853.1500, 853.2750, 853.3125, 853.6000, 853.7250, 853.9500
Wide frequencies: 851.3375, 851.3750, 852.4125, 852.4500, 852.6250, 852.9125, 852.9500, 853.1125, 853.5625, 853.7625, 853.9125
