In the world of ham radio, reliable power is essential. As ham radio operators, we often find ourselves in remote locations where access to the electrical grid is limited or non-existent. Solar power provides an efficient and sustainable solution, allowing us to maintain continuous operations while also promoting environmental responsibility. This article delves into the technical aspects of setting up and optimizing a solar power system tailored specifically for ham radio use, focusing on equipment, system design, and efficiency.

If you do not own a High Frequency (HF) radio, you may listen to HF radio using an Internet service, such as:

• - http://kiwisdr.ka9q.net:8073/ (located in San Diego, CA)
• - http://kiwisdr.com/public/
• - http://na5b.com/ (located Washington DC)

You do NOT need a ham radio license to listen.

### The Intersection of Ham Radio and 3D Printing: Innovations and Opportunities

Ham radio, or amateur radio, has long been a platform for communication enthusiasts to connect, experiment, and innovate. In recent years, the emergence of 3D printing technology has opened up new avenues for ham radio operators, enhancing their ability to create custom equipment and accessories. This article explores how these two fields intersect and the exciting possibilities that arise from their combination.

#### Customization and Design

One of the primary benefits of 3D printing in the ham radio community is

### What is it?

kv4p HT is a homebrew VHF radio that makes your phone capable of voice and text communication completely off-grid with at least a Technician class amateur radio license.

The radio simply plugs into the USB C port on your Android smartphone and transforms it into a fully-fledged handheld radio transceiver. It's completely open source (GPL3): the Android app, ESP32 firmware, PCB designs, and 3D printer files.

It's small enough to fit in your pocket and take anywhere, and since it has
