Hytera BD502i
DMR Digital + Analog — 48 Channels
IP54 — 16-Hour Battery — 3-Year Warranty
One of Hytera's best-selling commercial DMR radios — compact, rugged, and affordable with 48 channels, dual analog and digital operation, TDMA extended battery life, DMR Tier II repeater support, and a 3-year warranty.
The Hytera BD502i is a professional-grade commercial DMR two-way radio built for small businesses and organizations that want reliable, clear digital communication without complexity or high cost. It operates in both analog and digital (DMR) modes — making it a practical upgrade path for teams still running analog radios, since the BD502i can communicate with existing analog radios during the transition. With 48 channels across 3 zones, DMR Tier II repeater support for extended site coverage, TDMA-based digital operation delivering up to 16 hours of battery life, and IP54 and MIL-STD-810 durability — the BD502i delivers professional features in a compact, approachable package.
Available in VHF (136–174 MHz) and UHF (400–470 MHz) variants — see product options. Available at ITFactory.ca — Canada's trusted source for Hytera two-way radios and accessories.
Key Features
|
Dual Mode — Analog and Digital DMR on One Radio
The BD502i operates in both analog conventional and DMR digital modes — switching per channel. This allows it to work alongside existing analog radios on analog channels while taking full advantage of DMR's clearer audio, extended range, and longer battery life on digital channels. Ideal for teams migrating from analog to digital who need to maintain backwards compatibility during the transition.
|
48 Channels — 3 Zones with 16 Channels Each
48 channels split across 3 zones of 16 channels — with 24 analog and 24 digital channels available. Zone-based organization allows logical grouping by department, location, or function — keeping channel selection simple for users in the field. Supports mixed analog and digital channel reception, allowing scan across both channel types simultaneously.
|
|
DMR Tier II — Group, Private, and All-Call with PTT ID
Full DMR Tier II digital mode supports group calls (talk group to talk group), private calls (radio to radio), and all-call transmissions — each with PTT ID so dispatchers and team members can see who is transmitting. DMR Tier II also supports repeater operation for extended coverage across large sites, campuses, and buildings.
|
TDMA Technology — Up to 22-Hour Battery Life
DMR uses TDMA (Time Division Multiple Access), which transmits on alternating time slots — the radio transmitter is only active 50% of the time versus analog, reducing power consumption significantly. This delivers up to 16 hours (1500mAh battery) and up to 22 hours (optional 2000mAh battery) in digital mode — outlasting analog-only alternatives on the same charge.
|
|
Anti-Interference Digital Audio
Digital encoding and TDMA error correction reduce signal interference on shared frequencies — a significant improvement over analog where interference degrades audio quality progressively. DMR digital audio maintains clarity up to the edge of signal range, then drops out cleanly, rather than degrading into static. An integrated audio equalizer adjusts low, mid, and high-frequency gain for optimal performance in noisy and quiet environments alike.
|
IP54 and MIL-STD-810 C/D/E/F/G Durability
IP54-rated against dust ingress and water splashing from any direction — reliable in rain, dust, and outdoor job-site conditions. MIL-STD-810 tested across temperature extremes, temperature shock, vibration, humidity, and mechanical shock — the same standards applied to professional military communications equipment, confirming durability beyond typical commercial use.
|
|
Priority Scan and Emergency Alarm
Scan monitors multiple channels for activity — useful for supervisors and dispatch roles covering multiple teams. Emergency Alarm (programmable) allows a user to transmit an emergency signal to the group or dispatcher — critical for lone worker safety on construction sites, warehouses, and remote locations. Nuisance channel delete temporarily suppresses busy channels from scan without reprogramming.
|
Pseudo Trunking — Efficient Channel Use
Pseudo trunking automatically assigns available channels from a pool when a user transmits — reducing channel congestion in multi-radio deployments without requiring a dedicated trunking controller. Practical for sites with many radios that would otherwise compete for the same channel.
|
|
VOX — Hands-Free Operation
Voice Operated Transmission activates when using a compatible external earpiece or microphone accessory — enabling fully hands-free communication for workers operating equipment or handling materials. VOX sensitivity is programmable to suit different ambient noise environments.
|
Micro-USB Charging and Programming
The Micro-USB port provides charging via any standard USB charger and serves as the programming connection for channel and feature configuration. Simplifies charging infrastructure for multi-radio deployments — any USB power source charges the radio without a proprietary dock.
|
|
3-Year Warranty — Radio
The BD502i carries a 3-year manufacturer warranty on the radio — above average for the commercial radio category and an indicator of Hytera's confidence in the BD502i's build quality. Battery and accessories are warranted separately for 1 year.
|
Compact and Lightweight
At 120 × 54 × 29mm and 218g (with 1500mAh battery and antenna) the BD502i is one of the more compact DMR radios in its class — comfortable for all-day carry without belt fatigue, and accessible for users new to two-way radios.
|
Who Is This For?
The BD502i is the right radio for small businesses, schools, hospitality operations, warehouses, retail environments, and construction sites that want professional DMR digital communication at an accessible price point — especially teams transitioning from analog who want a radio that supports both simultaneously during the migration.

Frequently Asked Questions
Can the BD502i communicate with our existing analog radios?
Yes — the BD502i supports both analog and digital modes on the same radio, with channels individually configured as analog or digital. Channels set to analog mode communicate with standard analog radios on the same frequency and tone — making it easy to introduce BD502i radios into an existing analog fleet without replacing every radio at once. Teams can migrate channel by channel as budget allows, while maintaining full interoperability throughout the transition.
Does the BD502i need to be programmed before use?
Yes. The BD502i requires programming to configure channels, frequencies, tones, zones, and features before it is operational. Programming is performed via the Micro-USB port using Hytera's programming software and a compatible computer. For new deployments, contact an authorized Hytera dealer for professional programming. ITFactory.ca offers radio programming at a nominal fee — contact us before or after your purchase to arrange programming for your deployment.
What is the difference between DMR digital and analog in practical terms?
DMR digital audio is noticeably clearer than analog at equivalent signal levels, particularly in noisy environments — the BD502i's digital audio equalizer further optimizes voice clarity. Digital maintains full audio quality up to the edge of range, then drops out cleanly, compared to analog which degrades gradually into static. DMR also delivers significantly longer battery life through TDMA technology (the transmitter is active only 50% of the time vs analog). Additionally, DMR provides PTT ID, private calls, group calls, and repeater integration that analog cannot match.
Should I choose VHF or UHF?
VHF (136–174 MHz) performs best in open outdoor environments — large outdoor sites, farms, parks, and areas with minimal structural obstacles, where its 5W output and lower frequency propagation provide strong coverage. UHF (400–470 MHz) penetrates buildings, walls, and structural obstacles more effectively — making it the standard choice for warehouses, schools, hotels, retail stores, and mixed indoor/outdoor environments. If in doubt, UHF is the more versatile choice for most commercial and institutional deployments in Canada.

Radio Licensing Note
The Hytera BD502i is a licensed two-way radio. In Canada, operating a two-way radio on licensed frequencies requires a Radio Authorization issued by Innovation, Science and Economic Development Canada (ISED). The radio functions without a licence, but commercial operation on licensed frequencies without authorization is not permitted under the Radiocommunication Act.
