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.
N9SAB sent over a care package filed with lightweight, efficient, stealthy antennas for portable and fixed station ham radio use. Let's unbox them together!
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.
The Retevis Ailunce HD2 is finally here! Hereβs a short preview of the highlights. A few weeks before this post was published, Retevis reached out [...]
An amateur radio operator explores how detailed weather data could predict HF band openings, leveraging temperature, pressure, and historical contact information while considering the impact of cold on equipment conductivity.
Integrating the Ruuvi Gateway and sensors to remotely monitor indoor/outdoor temperatures, ensuring safe temperatures for lithium battery charging.
Off-Grid Ham Shack
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.
