Narva Mesh Network
Independent digital radio networking in Narva and Ida-Viru County
Narva Mesh Network is a digital radio network being developed by Narva Raadioklubi. With a small radio device, people can send messages and share their location with other participants. The device needs no SIM card or mobile coverage for this kind of communication.
Why build the network?
The network is useful in everyday life: exchange short messages, check the weather and receive local warnings. It also helps us develop additional ways to communicate in difficult situations. Range depends on location and nearby devices. In an emergency, call 112.
A network where messages travel by radio
Imagine walking along the Narva promenade, heading out of town or visiting the coast. You type a short message into a small radio device and it goes over the air. If the recipient is farther away, intermediate nodes may relay it. Together, participants help build the network.
Some nodes travel with people, while others stay in place and help extend coverage. Users can exchange messages, share their position and request useful information directly on their radio device, without a SIM card.
Narva is developing two technologies: Meshtastic and MeshCore. Both use low-power digital radio, but their devices cannot communicate directly with each other.
Useful information in one message
Our bots offer information directly over radio. Send /wx to the Narva channel for weather, /time for local time, /ping to check response and /signal for information about how your message was received. /help and /info explain more.
Replies arrive as short radio messages. /wx includes temperature, feels-like temperature, humidity, wind and air pressure. Our /road service is already running. Before a journey, request air and road-surface temperatures and surface conditions from road weather stations. Try /road tll towards Tallinn or /road trt towards Tartu.
Check the road before setting off
Wet pavement, dropping temperatures and changing conditions matter when planning a journey. Request road-station information over the radio.
Our own development: the Meshtastic–MeshCore bridge
Meshtastic and MeshCore are like two different languages. Devices in one network cannot directly understand messages from the other. Narva Raadioklubi has developed a software bridge that can carry selected messages between them.
A message posted on one side can cross the bridge and appear on the other, expanding the ways people can stay in touch without replacing every device.
The bridge does not merge the two protocols. These remain separate networks, with selected messages forwarded under defined rules.
Weather warnings focused on our region
Imagine an evening by the sea in Narva-Jõesuu: wind rising, waves building. That is when a concise, local warning becomes valuable. Our service focuses exclusively on Narva and Ida-Viru County.
A real example from today, 25 October 2026: the Estonian Weather Service issued a level-one strong-wind warning for Ida-Viru County, with south-easterly and southerly gusts of 15–17 m/s, valid from 19:00 on 25 October to 12:00 on 26 October.
This is how a warning can appear on a radio device: short and clear. The message below is an example.

We continue to develop radio-based warnings. Integrating official EE-ALARM notices is a separate future step. Call 112 in an emergency.
NRK Terminal OS 1.0
We are developing our own NRK Terminal OS 1.0 software for the compact LilyGO T-Deck Plus with a screen and keyboard. The terminal supports public and private messages, contacts and location information. Its home screen features messages, contacts, map, network, GPS and settings. The illustration shows the NRK Terminal OS 1.0 home screen.
The terminal currently runs on Meshtastic. We also plan to develop an NRK Terminal OS version for MeshCore, keeping the familiar interface and convenient messaging features.
