This tutorial explains how to modify Retevis Ailunce HD2's band for different IARU regions and outlines the advantages of DMR in ham radio, including text messaging.

The off-grid ham shack is fully energy self-sufficient, utilizing solar, wind, and other power sources, with a focus on low current devices for sustainable communication.

Summary: Retevis clarified AES128/AES256 encryption for the HD2 and confirmed, IT'S COMING!

The Retevis Ailunce HD2 is finally here! Here’s a short preview of the highlights. A few weeks before this post was published, Retevis reached out [...]

The Retevis Ailunce HD1 GPS, rated IP67 for dust and water resistance, surpassed expectations in extreme weather testing at -30°C, showing no signs of battery, LCD, or condensation issues after being left outside for three days. The robust HD1 performed admirably, suggesting it's a serious contender in rugged radio options.

The Off-Grid Ham Shack series discusses creating a self-sufficient ham radio station or 'Ham Shack' capable of operating on solar power during any grid down scenario, emphasizing the importance of an energy strategy for off-grid communications. This system includes solar panels, a charge controller, battery, and power distribution system. Key elements are the use of photovoltaic (PV) panels to harness solar energy, a solar charge controller to regulate energy flow and prevent battery overcharging or damage, and a battery to store energy for later. As well, power distribution ensures the allocation of power to multiple devices simultaneously. A grid-down energy strategy is crucial to any communication-related emergency, be it CB, FRS, GMRS, MURS or PMR radio, UHF CB, DMR, DStar, Meshtastic or LoRa communications.

There are very few words! Many of you already know what I would say, if I were going to say something. There’s no need for [...]
