Tech Prepper Demonstrates Reticulum on HF Radio, Using 1 Dummy Load to Avoid Encryption Ban

Summary
Reticulum was shown running over high-frequency radio as a fallback “post-internet” network, with The Tech Prepper framing it as a disaster-resilient alternative when normal connectivity fails.
1 dummy load replaced an antenna in the demo because encrypted transmissions are broadly banned on ham bands, letting the Mercury HF modem operate without radiating a signal outside the building.
Ubuntu-based EmComm Tools and modem73 formed the practical setup, highlighting how an open-source radio modem can link a PC into a decentralized cryptographic network stack.
The broader pitch extends beyond emergency use: modem73 can also run a legal, unencrypted BBS, and Reticulum had previously been demonstrated at shorter range over LoRa rather than HF.
