Looking back at the past month, I've learned far more about HAM radio than I expected. What seemed like a simple hobby revealed itself to be a deeply technical and nuanced field. From understanding how radios function to learning the legal and ethical frameworks that govern them, this journey has been eye-opening. Here are some of the key lessons that stood out.

Electrical Principles: The Backbone of HAM Radio

Understanding core electrical concepts was essential. Voltage, current, and resistance are not abstract ideas—they are the foundation of every radio system.

• Voltage provides the force that moves electrons.
• Current is the actual flow of electrons.
• Resistance slows that flow down.

Having a solid grasp of these fundamentals makes it easier to build and troubleshoot radio equipment and antennas.

Ohm's Law: More Than Just a Formula

Ohm’s Law finally clicked for me after studying it multiple times. It connects voltage, current, and resistance:

V = I × R

If you're designing a DIY antenna, Ohm’s Law helps determine resistance and component selection. It's also incredibly useful in diagnosing issues when something in your setup isn’t behaving as expected.

Capacitance and Inductance: Tuning Your System

Two concepts that became crucial as I dove deeper were capacitance and inductance.

• Capacitors store energy in an electric field.
• Inductors store energy in a magnetic field.

These components are vital when tuning circuits and designing systems for specific frequencies. For example, operating on HF bands often requires careful tuning for long-distance communication. Understanding how capacitors and inductors work together allows for more effective and efficient antenna systems.

Looking Ahead

My goal is to continue studying and earn my General License before the end of 2023. Fingers crossed that I can make the time!
