Meshtastic & MeshCore Guide — Houston / Spring / Conroe Area

Quick Comparison

Aspect	Meshtastic	MeshCore
Routing	Managed flood (every node can relay)	Only dedicated Repeaters relay
Max hops	7 (default often 3)	Up to 64
Best for	Ad-hoc groups, events, hiking, existing local meshes	Planned regional coverage with fixed repeaters
Airtime	Higher (more rebroadcasts)	Lower / quieter once paths are learned
Apps	Free, fully open source	Free core; some unlocks paid
Interoperability	None — different packet formats. Flash one at a time.

Hardware is shared. Most popular boards (Heltec V3, RAK4631, LilyGO T-Beam / T-Deck / T-Echo, etc.) can run either firmware. You just reflash.

Meshtastic

Open-source, long-range LoRa mesh. Every node can rebroadcast (managed flooding). Great for spontaneous groups and areas with existing activity.

Public Maps

meshmap.net (official public MQTT)
meshtastic.liamcottle.net
Texas Meshtastic Map (has Houston MQTT details)

Typical US start: Region = US, Modem preset = LongFast, Role = CLIENT (not Router & Client), Hop limit = 3. Enable “OK to MQTT” + position if you want to appear on public maps.

MeshCore

Repeater-based design. Companion (handheld) nodes do not relay by default — only dedicated Repeaters do. Quieter airtime and longer possible chains once infrastructure is placed.

Communities list: meshtexas.org/communities

Typical US start: Preset = USA/Canada (Recommended) ≈ 910.525 MHz, BW 62.5 kHz, SF7, CR 5. Role = Companion for handhelds; Repeater only for deliberate high sites.

Recommended Starter Settings (US)

Setting	Meshtastic	MeshCore
Region / Preset	US · LongFast (most common)	USA/Canada (Recommended)
Frequency (approx)	~906.875 MHz (LongFast)	910.525 MHz
Bandwidth / SF	Per preset	62.5 kHz / SF7
Role	CLIENT (handheld/mobile)	Companion (handheld) · Repeater only for fixed high sites
Hops	3 (raise only if needed)	Handled by protocol (up to 64)

Woodlands MeshCore note (as of late 2026): They run a primary 500 kHz profile (≈902.350 MHz, BW 500 kHz, SF11) as infrastructure default, plus the more common 910.525 / 62.5 kHz / SF7 secondary. Check their Discord for the exact current recommended preset before flashing.
