Welcome to the Web site of the Radio Station AA5TB. On these pages I try to share some of my mostly amateur (ham) radio activities and related projects with the world. This is a great life long hobby. In fact, it has been a major part of my life because it has effected it in so many ways. It has opened a lot of doors for me and exposed me to people and places that would have never been possible otherwise. I do play as an engineer at work but I attribute much of my fundamental RF knowledge to my experiences and interest in amateur radio. Ham radio came first for me, then college, and then work experience. 

If you are a new ham, keep in mind that this is a technical hobby as well. I know a lot of beginners these days associate ham radio only with public service and EMCOMM. Those are very important activities in ham radio but they are only important because historically, hams were a pool of radio electronics knowledgeable people that could be counted on when other communications failed. Don't be afraid to build something. Building is half the fun in this hobby. Even the simplest of projects can be loads of fun and a great learning experience. I think every ham should be able to build at least a dipole antenna from scratch.

Everything on these pages are of my own work unless stated otherwise. I did not design all of the projects but they were fun to build anyway. I've expanded on some of the technical items because at the time I felt that there was not enough information available to explain the subject matter completely. After much experimentation and study, I decided to put all of the information in one place. I don't claim to be an expert in anything but I do have a lot real life experience with much of the subject matter. However, confirmation from reputable sources is always recommended. I do try to provide some references at the bottom of my pages when possible to help with your research. I firmly believe that every ham should at least have the ARRL Handbook. Even older ones are extremely useful. They can often be found in libraries. If you can’t find an answer to your question in the Handbook, only then would I recommend asking on an Internet forum.

I try to respond to all of the e-mails but I am not always able to do so in a timely manner. Please don't be offended if you don't hear back from me. Sometimes messages just get lost in my mailbox.

I hope you enjoy my pages and thank you.
