My YouTube channel, @W1RCP, serves as a (hopefully) engaging place for Amateur radio (Ham radio) enthusiasts, where a passion for Parks on the Air (POTA) activations and hunting, ham radio tutorials, antenna building projects, QRP (low power) operations, and a mix of communication modes like CW (Morse Code), SSB (Single Side Band), and various digital formats shines through. Each video offers some sort of insights (or Easter eggs) and demonstrations, making radio topics accessible and exciting.

Channel Highlights:
Parks on the Air (POTA) Adventures: These videos feature my journeys to various parks, where I set up a portable station and make contacts. Episodes may or may not cover the planning and execution of these activations, but may also include the challenges of working in different environments, losing or forgetting parts of my portable station) and the excitement of logging contacts.

Antenna Experiments and Other Builds: Sometimes I showcases a variety of DIY antenna projects. Viewers can follow step-by-step guides on how to build and test antennas or other ham radio gear, optimizing their own setups based on my experiences and results.

QRP Operations: Occasionally I focus on the thrill and technique of making long-distance (and short-distance) contacts with low-power communications. These videos may highlight my own strategies for maximizing efficiency and effectiveness with minimal power, which is still a popular topic among ham radio hobbyists.

Morse Code (CW) and Digital Modes: Demonstrations on CW and various digital modes like FT8 or perhaps other modes offer both traditional and more modern communication methods. These videos might include decoding tips, software setups, and optimizing setups for different conditions.

Learning Together: I feature videos that are aimed at helping new or experienced hams to pick up something new or brush up on old or forgotten information. I mainly focus on CW practice in engaging ways and HAM TEST TRIVIA nights where we study actual license examination questions you might encounter when testing for a new license or an upgrade. Even if you've maxed out your levels of Amateur radio licenses, stay up to date with your knowledge of the hobby.

3D Printing for Ham Radio: Integrating modern technology, I love explore how 3D printing can be used to create custom parts for radios, antennas, or other project enhancements and toys. This unique angle not only appeals to amateur radio operators but also to tech enthusiasts and makers. I am a MAKER, and Amateur radio offers a wonderful avenue in engineering and tinkering.
