๐ DMR Fundamentals for VU Operators - Timeslots, Color Codes & Talkgroups
Understand the core concepts before diving into setup. DMR uses digital techniques that are different from analog FM.
๐ Related sections: Hotspot Setup โข Radio Programming โข Talkgroup Directory
Timeslots (TS)
TDMA Magic: 2 Conversations, 1 Frequency
DMR uses Time Division Multiple Access (TDMA) to split each frequency into 2 time slots of 30ms each. Your radio alternates between listening and talking in rapid succession.
TS1 (Timeslot 1)
- โข Usually for local/regional talkgroups
- โข VU India TG 5053 typically on TS1
- โข Regional nets and local activity
- โข Lower traffic, easier for beginners
TS2 (Timeslot 2)
- โข Usually for worldwide talkgroups
- โข TG 91 (Worldwide) typically on TS2
- โข International activity and nets
- โข Higher traffic, more activity
โ ๏ธ Critical: Your radio must be on the correct timeslot to hear traffic! Wrong TS = silence even if everything else is correct.
Color Codes (CC)
Digital "Squelch" System
Color Codes (0-15) act like CTCSS/PL tones in analog. They prevent interference between nearby repeaters on the same frequency by creating "digital bubbles."
How CC Works:
- โข Radio only responds to matching CC
- โข Wrong CC = radio ignores the signal
- โข Allows frequency reuse in same area
- โข Must match between radio and repeater
Common CCs in India:
- โข CC1: Most hotspots and networks
- โข CC2: Some regional repeaters
- โข CC0: Simplex and some repeaters
- โข CC3-15: Area-specific assignments
๐ก VU Tip: Start with CC1 for hotspots. Check local repeater directory for CC assignments.
Talkgroups (TG)
Static TG
Always active on repeater/hotspot. Traffic always passed through.
Best for: High-activity groups, daily nets
Dynamic TG
Activated by first TX. Times out after 10-15 minutes.
Best for: Occasional use, special events
Private Call
Direct radio-to-radio using DMR ID instead of TG.
Best for: One-on-one conversations
Network Types
BrandMeister: Most popular worldwide
TGIF: The Group in Focus
FreeDMR: Free and open source
๐ก Choose: BrandMeister for most VU activity
DMR ID
Required: Unique 7-digit number
Format: 31055xx (VU3 example)
Register: Free at RadioID.net
โ ๏ธ Important: Cannot transmit without valid ID
How DMR Works
Digital: Voice converted to data packets
TDMA: Two conversations share one frequency
Internet: Links repeaters worldwide
๐ฏ Result: Talk globally with low power
๐ DMR Signal Flow
โ๏ธ How DMR Actually Works
Understanding the technical magic behind Digital Mobile Radio - from TDMA to internet bridging
๐ TDMA: Two Conversations, One Frequency
Time Division Multiple Access
- โข Each frequency is divided into 30ms time frames
- โข Frame split into 2 slots: TS1 (15ms) and TS2 (15ms)
- โข Radio alternates between listening and talking slots
- โข Allows 2 simultaneous conversations on one frequency
- โข 6.25kHz equivalent bandwidth efficiency
Real Example
Both happen simultaneously on 433.200 MHz!
๐ก DMR Repeater Operation in India - How VU Networks Work
RF Reception
