5 DMR Radios for Tier 2 Simplex Teams in 2026 (HP605 vs DP1400, 240g IP67, 19-28h Battery)
Your crew does not need a repeater - it needs radios that actually talk to each other on the same simplex channel. HP605, DP1400 and DP2400e compared: cross-brand DMR Tier 2 interoperability, battery math, and the analog-to-digital migration path for small teams.
| Specification | 240g / IP67.. | Compact budget for.. |
|---|---|---|
| Hytera HP605 | 240g / IP67 / 22h / 256 channels | Compact budget for mixed-brand teams |
| Hytera HP705 | 256 channels / IP67 / 22h / GPS | GPS-tracked field crews |
| Motorola DP1400 | 98 phon / IP54 / 1,500mAh / 19h / 310g / 32 channels | Analog-to-DMR migration entry |
| Motorola DP2400e | 2.0-inch color display / IP67 / 2,900mAh / 28h / 295g / Wi-Fi+BT+GPS | Warehouse and depot crews, OTAP |
| Motorola DP4600e | No display / IP67 | Glove-friendly field workhorse |
| Motorola R2 | 101 phon / IP55 / 2,800mAh / 28h / 295g | Entry Linux-platform upgrade |

Tier 2 simplex means no repeater - radios talk direct, unit to unit, so the whole buying decision is about who must hear whom and for how long. Cross-brand interoperability on a shared simplex channel is governed by the ETSI TS 102 361 DMR standard, not by brand loyalty: a Motorola DP1400 and a Hytera HP605 will pass voice on the same channel when color code and talkgroup are programmed to match. What does NOT interoperate across brands is encryption - r/HamRadio testing confirms Baofeng AES-256 will not talk to Motorola, while Hytera units work in open DMR Tier 2 - so treat encryption as a same-brand fleet decision and open DMR as the mixed-fleet default. Then match hardware to the shift: the 19h DP1400 forces a mid-shift battery swap on 12-hour runs, the 22h HP605 and HP705 cover a full shift with margin, and the 28h DP2400e and R2 clear double shifts without spare batteries. Display is the last fork: DP1400 and HP605 are voice-first, DP2400e adds a 2.0-inch color display with Wi-Fi, Bluetooth and GPS for over-the-air reprogramming and position tracking, and DP4600e drops the display entirely for glove-friendly field operation.

For teams under roughly ten units, simplex kills the entire repeater cost stack - infrastructure unit, antenna, duplexer, installation and recurring trunking entitlements - and the savings fund better portables instead. The cost lever is per-unit mix: an HP605 (240g, IP67) at budget pricing next to an R2 (101 phon, 28h) on the same channels lets a fleet spend where it hurts - premium audio on the loudest floor, compact budget units everywhere else - provided programming (color code, talkgroups, channel spacing) is verified before shipment. Migration is the compliance play: analog-to-DMR happens under the same licensed business-band regime, and DMR adds per-radio ID, text and GPS without buying a second system; DP1400's 32 channels make it the proven entry point, and its 98 phon audio still cuts through site noise. Do not skip the license check: an unlicensed simplex fleet is a fine, not a feature, and interop on shared channels requires identical repeater-independent settings across brands.
