There are dozens of local Amateur Radio Clubs in the DFW area. The list below is not exhaustive, but represents most of the region. Meeting and testing times are subject to change, so verify with the clubs themselves before going.

Getting your FCC license is a fairly straightforward process. There are a few hoops to jump through, but the biggest asset is your brain. Once licensed, it is good for 10 years and you do not have to re-test for renewal as long as you do not let it lapse (there is some other fine print, but that’s the jist). Fees do apply along the whole process, so plan to spend about $100 on study materials and the licensing exam process.

One of the great things about the FCC licensing system is that the exam materials are published publicly. There are various ways to absorb the material. With that said, the material changes every 4 years, so you need to make sure you have the correct materials.

You may read the full Code of Federal Regulation Documents for Part 15 HERE and Part 97 HERE.

Part 15 permits the existence of unlicensed “low signal” emissions and all of the regulations that they are subject to. Part 15 regulates power output by Signal Strength or Maximum Effective Isotropic Radiated Power (EIRP). As a result, you must consider both the Transmitter Output Power and the Antenna Gain for your project.

Part 97 augments section 15 and creates a tiered privilege system among a specific assortment of frequency bands. The three levels of privilege are Technician, General, and Extra. Each level unlocks specific frequency ranges and/or specific modes of operation. Additionally, Part 97 only regulates Transmitter Output, with no limitation upon antenna gain. However, there are other factors to keep in mind.
