SLR 1000 vs HR655 — Compact DMR Repeaters: 10W Motorola vs 50W Hytera Architecture

Motorola SLR 1000 — 10W Ultra-Compact DMR Repeater with IP65, Wall/Pole Mount, and 8-Hour Battery Backup at 5kg

Ultra-compact 10W DMR repeater with IP65 outdoor-rated enclosure — the only direct-weather repeater in this class. Passive cooling eliminates fan failure points. Wall- or pole-mountable at 5kg — no rack needed. TDMA dual-slot doubles voice paths on a single 12.5kHz channel. -119 dBm receiver sensitivity. Integrated 8-hour battery backup with automatic switchover. Supports Capacity Plus and IP Site Connect for up to 15 sites. AES-256 encryption. Designed for parking structures, tunnel coverage, remote construction sites, and rooftop installations where outdoor exposure, passive cooling reliability, and zero-rack deployment justify the lower 10W output.

Hytera HR655 — 50W Compact DMR Repeater with 1024 Channels, Mixed-Mode Auto-Detection, and XPT Trunking

High-power 50W compact DMR repeater — 5x the output of SLR 1000. 1024 channels across 64 zones. Mixed-mode analog/digital auto-detection enables seamless migration. 0.18μV analog sensitivity with intelligent squelch control. Supports Hytera XPT digital trunking for pseudo-trunk expansion without licensing fees. 2U rack design with front-panel LCD for local diagnostics — requires indoor installation. No IP65 rating — not designed for outdoor direct-weather deployment. Dominant in multi-floor office buildings, industrial workshops, and campus systems where 50W reach, 1024-channel flexibility, and mixed-mode migration capability justify the indoor rack requirement.
