Today we talk about several different numbering schemes. Two of which we find in the scanner radio environment.
What You Will Learn in This Week's Podcast:
- Decimal system can be thought of as human-readable digits.
- These are easy to use to read and compute.
- They are also easy to convert from one form to another.
- While decimal works well with humans, it is not the case with computers.
- Binary language is used for them. It has two bits 0 and 1.
- Octal is a 8 bit system. This is how we save a little bit of room in a system.
- 0-7 make up 8 bits.
- Hexadecimal (Hex) is a 16 base system with values from 0 – F.
- There are no numerical symbols that represent values greater than nine, so letters taken from the English alphabet are used, Hexadecimal A = decimal 10, and F = decimal 15.
- I stick to decimal format when I program talk groups into my scanners.
- When you look at Radio Reference, Trunk SysIDs and WACN are in Hex.
- RFSS and Site ID’s are shown in Decimal with Hex in parenthesis.
- Talk groups on Radio Reference have a column for Dec and a column for Hex.
