Hytera HR659 Compact DMR Repeater — Detail

Technical assessment

The Hytera HR659 operates across UHF: 400–470 MHz; VHF: 136–174 MHz. Several band versions exist; which one to buy follows from the frequency assigned to your organisation. UHF passes between walls and obstructions more readily, which is why it is preferred inside buildings, industrial plants and dense urban areas. VHF carries further over open ground and water at the same power.

RF output power is High-power version: 1–25 W adjustable; low-power version: 1–10 W adjustable. More power is not automatically better: it extends range and shortens battery life at the same time. Teams working close to a repeater are usually served by the low setting, which also lengthens the shift.

Capacity is 1024 channels. The channel plan is designed inside that limit, and headroom should be left at the start so that growth does not force a reprogramming exercise.

Battery 12.5 Ah (optional).

Receiver sensitivity is 0.18 μV @ BER 5%. Sensitivity states how weak a signal the radio can still decode, and a lower number is better. At the edge of coverage it determines range as much as transmit power does — communication usually fails not because the other party cannot hear, but because the radio cannot decode a weak signal.

Operating temperature range is -30°C ~ +60°C.
