Buyer's guide The EDICT-HP, by the numbers

How durable are the EDICT-HP and other high-power Meshtastic radios?

The EDICT-HP comes sealed, and none of the 1 W-class radios under $200 in our open tier list do: every unit is fully silicone potted after assembly, which fills the space around the circuit board and seals the electronics in silicone. The potted electronics sit in an MJF Nylon 12 shell, an industrial 3D-printed nylon, with powder-coated aluminum top and bottom plates. The four 1 W-class options under $200 in the list, the RAKwireless WisMesh 1W Booster kit, two Pi Mesh 1W Hats and the B&Q Station G2, are bare boards or open stacked circuit boards with no water rating. Those are good choices for builders who want to make their own enclosure.

Where and how are the EDICT-HP and other high-power Meshtastic radios made?

The EDICT-HP is designed and assembled in Illinois from US-made enclosure parts: its MJF nylon shell is printed in the USA and its aluminum plates are machined in the USA, and every unit is assembled and tested in-house, then fully silicone potted. Delta Plus Proto designed the 1 W RF platform itself rather than using an off-the-shelf board; the circuit board is the only part made outside the USA. The EDICT-HP uses a Semtech SX1262 radio chip and a Nordic nRF52840 processor, the same core chips found in most Meshtastic radios: 28 of the 37 radios in our tier list use the SX1262.

How much does an EDICT-HP high-power Meshtastic radio cost?

The EDICT-HP costs $179 for the radio. The battery, antenna and charger are not included: the EDICT-HP runs on standard Baofeng UV-5R battery packs and takes any SMA antenna for 902–928 MHz, so packs and antennas you already own will work. There is no subscription or service plan, and shipping is calculated at checkout from live carrier rates.

Who should buy an EDICT-HP high-power Meshtastic radio?

Buy the EDICT-HP if you want 30 dBm (1 W) of transmit power, about six times the 22 dBm (158 mW) of a standard Meshtastic radio, in a potted radio that runs on field-swappable Baofeng UV-5R packs. The EDICT-HP suits people who already own Baofeng packs or chargers, and anyone who wants a stronger signal than a standard Meshtastic radio. If you want a built-in battery that lasts 2–4 weeks and a machined aluminum case instead, choose the NPH-1.

Overview EDICT-HP in detail

Description

EDICT-HP — High Power Mesh Radio

The EDICT-HP is a rugged, high-power mesh radio built for reliability in real-world conditions.

Powered by standard Baofeng UV-5R battery packs, it enables hot swapping in the field, extends runtime, and eliminates proprietary limitations.

At its core is a purpose-built RF platform engineered for range, sensitivity, and efficiency — not an off-the-shelf board, but a system designed to push Meshtastic performance further.

Core Architecture

Engineered for Real-World Performance

  • Cleaner transmit signal with reduced interference
  • Improved receiver sensitivity for better link reliability
  • Stable performance at higher transmit power
  • More consistent long-range communication

FAQ EDICT-HP questions

What is the EDICT-HP Meshtastic radio?

The EDICT-HP is a high-power LoRa mesh radio designed and assembled by Delta Plus Proto in Illinois, USA. It transmits 30 dBm (1 W) conducted on the 902–928 MHz US ISM band from a Semtech SX1262 with a 1 W power amplifier, and runs Meshtastic or MeshCore firmware (Reticulum coming soon) on hot-swappable Baofeng UV-5R battery packs.

Does the EDICT-HP come with a battery and antenna?

No. The EDICT-HP ships as the radio only: it runs on standard Baofeng UV-5R battery packs and takes an SMA antenna for 902–928 MHz, and the battery, antenna and charger are not included.

What frequency band does the EDICT-HP use?

The EDICT-HP operates on 902–928 MHz, the US ISM band. Check that band is permitted where you'll use it before taking the EDICT-HP outside the US.

Which firmware does the EDICT-HP run?

The EDICT-HP runs Meshtastic or MeshCore, with builds tuned for its 1 W amplifier on the Downloads page. A Reticulum (RNode) build for the EDICT-HP is coming soon.

How do you update the firmware on the EDICT-HP?

Double-tap reset on the EDICT-HP, then drag the firmware file onto the USB drive that appears, and the radio reboots on the new firmware. The DeltaMeshFlasher desktop tool for Windows, macOS and Linux can flash it too.

Does the EDICT-HP have Bluetooth?

Yes. The EDICT-HP uses a Nordic nRF52840 processor with Bluetooth LE and an internal chip antenna.

What is inside the EDICT-HP?

The EDICT-HP pairs a Semtech SX1262 LoRa radio with a 1 W power amplifier for 30 dBm (1 W) conducted output. On receive, a SAW filter, which blocks signals outside the band, sits in front of a low-noise amplifier (LNA) that boosts weak incoming signals.

Does the EDICT-HP ship internationally?

Yes. The EDICT-HP ships from Illinois to US and international addresses, with carrier rates calculated live at checkout. Check that 902–928 MHz is permitted where you'll use it first.
