Beyond the Basics

an EDACS trunked system

Your scanner shows EDACS talk groups in AFS (Agency- Fleet-Subfleet) format. This helps you see, at a glance, who you are monitoring. And with the partial-entry feature, you can easily include nearby, related channels in the same fleet or agency. You can just as easily exclude entire unwanted fleets and agencies.

When in search mode, with the system frequencies programmed, and your scanner locked to the control channel, you can select a desired city by keying in the agency part of the AFS talk group. When you hear an interesting talk group, in hold mode capture it to your scan list by pressing E during the transmission. Or hold on it by pressing

HOLD/RESUME.

Your scanner can also work in decimal format. Talk group 03- 62 in decimal format is 402. But decimal format does not give you any information about the system hierarchy. Decimal is useful if you need to work from decimal talk group lists.

AFS partial entry

AFS is a method of encoding EDACS talk groups. AFS stands for “Agency-Fleet-Subfleet”. AFS talk groups are used in all EDACS reception -- in ID search, ID lockout and ID scan. The powerful AFS partial entry feature designed into the scanner lets you use either a complete talk group code, or just the most significant part.

This feature lets you expand or narrow searching and scanning to one of 4 levels. By entering only the desired part of an AFS talk group, you can select 2048 talk groups, 128 talk groups, or 8 talk groups. For example, you could program every talk group in a police department with just 4 key presses. You can use the AFS partial entry feature
