🖥 IW2OHX-14 (X)NET DLC7 Node

(X)NET is a multi-protocol packet radio node software (digipeater/router) developed by Jimy, DL1GJI. It is one of the most capable AX.25 node systems available, supporting up to 250 simultaneous users, NET/ROM, and FlexNet routing protocols, as well as AXIP and AXUDP over Ethernet — bridging traditional RF packet radio with modern IP networks. The IW2OHX-14 node runs (X)NET natively on a DLC7 (Data Link Controller 7), a high-performance TNC built around a 32-bit ARM7 microcontroller with 4 MB Flash and 32 MB RAM and native Ethernet connectivity.

📶 HAMNET — Highspeed Amateur Radio Multimedia Network

HAMNET is a high-speed IP network built and operated by radio amateurs across Europe, conceived by Jann Traschewski (DG8NGN) and the German Amateur IP-Coordination Team. Operating primarily on the 6 cm band (5.6–5.8 GHz), HAMNET interconnects relay stations, digipeaters, and amateur services at speeds from 1 Mbit/s up to 1 Gbit/s using commercial wireless equipment such as Mikrotik RouterBoards and Ubiquiti radios. The network leverages the international AMPRNet (44.x.x.x) address space, BGP routing between autonomous systems, and has largely replaced the legacy Packet Radio backbone in Central Europe since 2008. By 2016 it counted over 4,000 nodes and continues to grow beyond the German-speaking regions.

📡 LoRa APRS — Long Range APRS on 70 cm

LoRa APRS combines Long Range (LoRa) chirp-spread-spectrum modulation with the Automatic Packet Reporting System (APRS), enabling position reports, weather data and messaging over the 70 cm band. Unlike traditional 2 m FM AFSK, LoRa signals can be decoded well below the noise floor, delivering exceptional range with low-power ESP32-based hardware. The IARU Region 1 recommended frequency is 433.775 MHz (uplink), with 433.900 MHz for the downlink. LoRa APRS is fully interoperable at the application layer with conventional AX.25 APRS — all stations appear on aprs.fi alongside legacy 2 m traffic. Typical hardware cost starts at around $20 for an iGate and $35 for a tracker, using boards like LILYGO T-Beam or LoRa32.

🌐 MeshCore — Off-Grid LoRa Mesh Network

MeshCore is a lightweight, open-source C++ library that enables multi-hop packet routing for LoRa radios, creating resilient, decentralised communication networks that work entirely without the internet. Unlike traditional mesh protocols, MeshCore minimises radio chatter through a hybrid routing approach, combining low power consumption with end-to-end encryption for private messages. It runs on popular ESP32-based LoRa hardware such as the RAK WisBlock, Heltec V3/V4, LilyGo T-Beam and T-Deck. Supported by an active open-source community, the MeshCore network has grown to over 16,000 monitored nodes worldwide as of early 2026.

✉ Winlink — IW2OHX RMS Gateway

Winlink is a worldwide volunteer-operated radio messaging network that provides email with attachments, position reporting, weather bulletins, and emergency communications over amateur-band radio frequencies. The system can operate completely without the internet using smart-network radio relays. It follows a three-layer architecture: Common Message Servers (CMS) hosted on redundant cloud infrastructure, Radio Message Servers (RMS) that act as gateways between radio and the internet, and clients running Winlink Express software. Messages originating on Winlink can be delivered to any standard email address via the CMS SMTP gateway.
