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 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 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.
Ham Radio LiFePO4 battery powers 4500psi air compressor off-grid!
In May 2023, Julian OH8STN, Ed WQ2U, and Oliver DL4KA set off on an off-grid communications field test above the Arctic Circle. The team aims to test new strategies for off-grid communications, spanning portable power, robust hardware, and antenna efficiency. The expedition will take place near Rovaniemi, Finland. Also, part of the testing includes new robust packet radio capabilities and power supplies. The team encourages interaction from the community via Winlink and APRS messages.
