Long-range LoRa
Low-power radio links designed for practical messaging over challenging terrain.
MeshCore • Yorkshire
A community-built MeshCore network for resilient, off-grid messaging across Yorkshire.
Built by the community
MeshCore uses low-power LoRa radios to pass short text messages from node to node. No mobile signal, subscription or central service is needed.
MeshCore Yorkshire brings local operators together to extend useful coverage, share knowledge and help more people get connected.
Low-power radio links designed for practical messaging over challenging terrain.
Repeaters help messages travel beyond the direct range of a single device.
Built around licence-exempt devices operating within UK radio regulations.
Getting started
You do not need an amateur radio licence or a complicated station. A compatible LoRa device, the MeshCore firmware and the same radio settings as the local network are enough to get started.
For everyday messaging, choose a companion device that connects to your phone by Bluetooth. A screen-and-keyboard device can operate by itself. Fixed repeaters are for extending coverage rather than sending messages.
Flash the correct MeshCore firmware for your board, then install the MeshCore companion app on your phone. Give your node a recognisable name and set its role to Companion.
Use the UK frequency and matching LoRa parameters below. Every value must match; a node on a different frequency, bandwidth, spreading factor or coding rate will not hear the network.
Yorkshire radio profile
This is the shared profile used by MeshCore Yorkshire. Stay within the UK licence-exempt power and duty-cycle limits for your equipment and installation.
Meet the local network
#Yorkshire is the public community channel for local chat, coverage reports, testing and getting help from other node operators.
Direct messages are private between contacts; public channel messages may be seen and repeated by other nodes across the mesh.
Start here
Choosing a device
Start with one companion node. Add a repeater only when you understand your local coverage and have a genuinely useful location for it.
Once configured, leave your node running for a few minutes so it can hear advertisements and discover nearby contacts.
How the mesh works
Your companion learns which repeaters can reach a contact and sends a short encrypted packet along a suitable path. Repeaters forward it; Room Servers provide a shared place where messages can be stored and collected later.
Coverage is never guaranteed. Terrain, buildings, antenna position, interference and the nodes currently online all affect whether a path is available.
Your personal identity on the mesh. It connects to the app or provides its own screen and keyboard, manages contacts and sends direct or channel messages.
Unattended infrastructure that forwards packets. It does not replace your companion and is most valuable in a high, clear and reliable location.
A persistent meeting place that can hold room messages for users to retrieve. It serves a different purpose from a pure coverage repeater.
A useful first test
Building useful coverage
A modest repeater with a clear view will often outperform a powerful node hidden behind walls or surrounded by electrical noise. Plan for reliability, not an impressive bench-test figure.
Look for legal access, clear horizons, safe maintenance and a location where the node benefits more than one household.
Use a suitable 868 MHz antenna, short low-loss feed where possible, sound connectors and separation from noisy electronics.
Weatherproof outdoor equipment, provide battery margin for poor weather and keep a record of firmware, settings and admin access.
Repeater configuration
Regions tell a repeater which scoped flood traffic it should forward. Use yorkshire as the primary region, with the neighbouring regional identifiers below added as extras.
yorkshireThe main Yorkshire community scope.
eng-yhThe England–Yorkshire and the Humber regional scope.
eng-neThe North East England scope, useful for cross-boundary paths.
gb-eng-nwThe North West England scope, useful for routes across the Pennines.
Suggested CLI sequence
Log in to the repeater, open its CLI and enter one command at a time. Wait for an OK response after every command. The final command saves the region configuration permanently.
region put yorkshire
region allowf yorkshire
region put eng-yh
region allowf eng-yh
region put eng-ne
region allowf eng-ne
region put gb-eng-nw
region allowf gb-eng-nw
region saveSuggested, not one-size-fits-all: these regions have been recommended for Yorkshire repeaters, but an operator may need different settings for their location and neighbouring network. Region identifiers are case-sensitive; enter them exactly as shown.
Quick checks
Confirm the device has Companion firmware, Bluetooth is connected, the antenna is fitted, and frequency, bandwidth, SF and CR exactly match the Yorkshire profile. Then wait several minutes outdoors or near a window.
Reception does not prove there is a return path. Move to a clearer position, allow path discovery to update and test a nearby contact before assuming the repeater is faulty.
Use Chrome or Edge on a computer, try a known data-capable USB cable and select the exact hardware model. Many USB cables provide charging only.
Check noise level, antenna and connector losses, nearby electronics, enclosure placement and power stability. More transmit power cannot repair poor reception or a blocked site.
Responsible UK operation
Use 868 MHz hardware and operate within the power, spectrum-access and duty-cycle conditions that apply to the chosen sub-band. Antenna gain and any amplifier count towards radiated power. Install repeaters only with the landowner’s permission and never where they could create a safety or access risk.
MeshCore Yorkshire is a community communications network, not an emergency service and not a replacement for 999.

Using it well
Getting firmware onto a device is only the beginning. Good discovery habits, sensible repeater maintenance and clear expectations make MeshCore Yorkshire more reliable for everyone.
Finding other people
An advert announces your node identity so other companions can add you as a contact and learn how to reach you. Both ends may need to advertise before reliable direct messaging is possible.
Good practice: advertise once, wait for the mesh to respond and avoid repeatedly flooding adverts. More adverts do not create better coverage; they consume shared airtime.
For repeater operators
A remote repeater should be documented and recoverable. Make changes deliberately, keep known-good settings and plan physical maintenance before a fault occurs.
Privacy & security
Messages posted to #Yorkshire may be received and repeated across the community network. Never post confidential or sensitive personal information.
Node names and adverts are visible to others. Avoid including a home address, telephone number or other unnecessary personal details.
Only publish precise coordinates when appropriate. Infrastructure locations may reveal private homes or restricted sites.
A private key identifies the node. Keep backups securely where supported; a full erase may generate a new identity and break existing contacts.
Direct messaging provides privacy features, but MeshCore is a community radio system—not a guaranteed secure or emergency communications service.
If you discover abuse, unsafe infrastructure or a security concern, contact the project without publishing sensitive details in a public channel.
Made for Yorkshire
Short messages between groups where valleys, moorland and patchy mobile coverage make ordinary communication difficult.
Hands-on radio, networking and resilient-communications activities for Scouts, JOTA/JOTI and youth technology events.
Coordinate operators, equipment and visitors around temporary amateur-radio stations without loading the mobile network.
Supplementary messaging around shows, camps, outdoor activities and volunteer-led events.
Test antennas, paths, terrain and low-power radio propagation while contributing useful observations to the community.
A pre-arranged backup for short local messages when normal services are unavailable—never a replacement for 999.

About the project
MeshCore Yorkshire is a volunteer-led community encouraging useful, responsible off-grid messaging across the county. It is not a commercial network, formal emergency service or guarantee of coverage.
