Motorola SLR 5700 Repeater AAR10QCGANQ1AN UHF 50W

Motorola SLR 5700 MOTOTRBO DMR Digital/Analog Repeater (MPN: AAR10QCGANQ1AN)

The Motorola MOTOTRBO™ SLR 5700 (Model: AAR10QCGANQ1AN) is an enterprise-grade, high-efficiency 1U rack-mount DMR/analog base station engineered for continuous-duty operation in demanding environments. Built specifically to resolve RF attenuation across compartmentalized steel superstructures, offshore platforms, shipboard machinery spaces, and heavy industrial facilities, the SLR 5700 operates across the UHF 403–470 MHz band with an adjustable 1 to 50 Watt RF power output.

The unit integrates high-sensitivity receiver architecture, advanced digital error correction, and 2-slot TDMA technology to deliver two simultaneous voice/data channels over a single 12.5 kHz physical allocation. Featuring integrated AC-to-DC power switching (100–240V AC, 4A max) alongside an automatic 12V DC battery revert system with an internal 3A float charger, the SLR 5700 ensures uninterrupted mission-critical communications even during primary bus power drops.

Frequently Asked Questions

What frequency band does the Motorola SLR 5700 model AAR10QCGANQ1AN cover?

Model AAR10QCGANQ1AN operates specifically across the UHF 1 spectrum, covering 403 MHz to 470 MHz. This band is ideal for penetration through steel bulkheads, concrete walls, multi-level decks, and heavy industrial plant layouts.

Can the SLR 5700 operate simultaneously on both digital and analog modes?

Yes. The SLR 5700 features Dynamic Mixed Mode (DMM). It automatically switches between analog FM and digital DMR modes based on the incoming call type received from field portables or base stations, allowing a smooth phased migration path from legacy analog systems to digital DMR.

How does the automatic battery backup (DC revert) system work?

The SLR 5700 includes built-in DC power failover circuitry and a 3A battery maintenance charger. Connect a 12V DC auxiliary battery bank to the rear DC terminal block while the unit runs on 100–240V AC. If primary AC mains fail, the repeater transfers operation to the DC battery instantaneously without dropping active calls or resetting the unit.

Can this repeater be integrated with IP Site Connect for remote or shore links?

Yes. The onboard 10/100 Ethernet port supports MOTOTRBO IP Site Connect. This allows multiple SLR 5700 repeaters on different vessels, work sites, or remote operational facilities to link over standard IP LAN/WAN networks for seamless wide-area roaming.

What is the maximum continuous duty cycle of the SLR 5700 at 50 Watts?

The SLR 5700 is rated for a 100% continuous duty cycle at its full 50-Watt RF output. It is engineered for 24/7/365 heavy voice dispatch, digital data, and trunking operations without thermal tripping under high ambient temperatures up to +60°C (+140°F).
