Keeping the Ham Shack & my Lithium batteries warm in winter
To protect lithium batteries from cold while charging, a video/blog showcases using a Chinese diesel heater in an off-grid ham shack. It’s vital to keep batteries above freezing, a lesson learned from electric cars in winter. The video details the installation and operation of a 3kw Vevor diesel heater, which also powers up using the ham shack’s LiFePO4 batteries, maintaining ideal temperatures for both batteries and equipment.

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.
