TRUNKTRACKING SCANNERS
General Questions
Product: General Information
Question: What is trunktracking and where can I get more information?
Answer: Trunking communications systems let a large group of 2-way radio users (or even different groups of 2-way radio users) efficiently use
a large range of frequencies. Instead of selecting a specific frequency for a transmission, the user simply selects a talk group. The trunking
system automatically transmits the call on the first available frequency and also sends (on a different frequency called a data channel) a code
that uniquely identifies that transmission.
Since the trunking system might send a call and its response on different frequencies, it is difficult to listen to trunked communications using a
regular scanner. Trunking scanners let you select and monitor the data channel frequency sent with a 2-way radio transmission, so you can hear
the call and response for that user and more easily "follow" the conversation.

Question: How do I convert EDACS SYSTEM ID format (decimal to AFS)?
Answer: Our scanners use either decimal format or decimal and AFS format. You can convert decimal EDACS IDs to the AFS (Agency-Fleet-
Subfleet) format as follows:
The example below starts with the Decimal ID 0586.
1. Convert Decimal to Binary
586 decimal = 01001001010 binary
ID's are 11-bit binary. If you get a binary that isn't 11 bits,
just add leading zeroes until you get 11 bits.
2. Split the binary as follows #### / #### / ###
0100 / 1001 / 010
3. Convert each GID to decimal
04 09 2
4. Format as ##-###
04-092
