RF in the Shack

After finally getting my RF rig set up an tested, I've had a few unusual problems which have convinced me that I need to re-think how I am doing things. In this post, I will talk about the common problems that I am having testing out my new radio, and what I have done to mitigate the problems.

Lesson 10- Interference with Nearby Electronics

When I first started playing with my HF radio, I noticed something strange. When I talked on 20m, I could hear sound coming out of a set of near by computer speakers. I haven't extensively studied it out, but I believe that the speakers are poorly shielded, and actually acting as a poor radio receiver. Similarly, I have had computer speakers in the past that amplified AM Radio stations in the area. In this lesson, I will better familiarize you with the source of such interference, and what you need to do as a ham radio operator to mitigate it. I should state up front, don't take any of this as legal advice.
