Retevis Ailunce HD1 GPS First impression
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.
Building a Solar Powered Ham Radio Station
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.
