Start studying for the license exams. Do not be intimidated by the word “study,” because most people can go from knowing abso- lutely nothing about amateur radio to passing the Novice and Technician written exams in less than a month.

The exams test your knowledge of basic radio regulations and el- ementary radio theory. Many clubs hold license classes which can be a fun and easy way to learn about amateur radio. There are good books, cassette tapes, computer programs, and many other study aids available. Your local RadioShack store sells FCC License Preparation study guides for amateur radio operator li- censes. While you are no longer required to learn Morse code for a Technician Class license, we encourage you to learn it anyway so you can advance to higher levels of operating privileges.

There is no fee to take the Novice exam. As soon as you pass the Novice exam, you can immediately take the Technician exam. There is a small fee required for taking the Technician exam. All license level tests are administered by a three-member Volunteer Examiner Team. Contact the ARRL for a schedule of exam op- portunities in your area.

The Technician Class license lets you use the HTX-400 to com- municate directly with other operators, and use repeaters for dis- tant communication.

Amateur radio is a great hobby that has enriched the lives of mil- lions of people all over the world. The ARRL would be glad to hear from you if you need more information or would like to join!

HTX-400 specifications

The Radio Shack HTX-400, introduced in the mid-1990s, remains a beloved model among amateur radio enthusiasts and collectors. Known for its reliability and versatility, this transceiver is particularly notable for its compact design and user-friendly interface. The HTX-400 operates on both VHF and UHF frequencies, enabling users to communicate effectively across various channels.

One of the HTX-400’s key features is its output power, which is adjustable between 1 and 40 watts. This flexibility allows operators to choose their transmitting power based on the communication needs and conditions of their environment. The device operates on the 2-meter band, covering the frequency range of approximately 144 to 148 MHz, making it ideal for local communications as well as a part of emergency communication networks.

A significant technological aspect of the HTX-400 is its digital display, which provides clear readings of frequency and signal strength. Users appreciate the intuitive control layout, which allows for quick adjustments and easy channel changes. The built-in memory function can store multiple frequencies, providing users with the ability to switch quickly between channels they use frequently.

Another standout feature is its CTCSS tone encoding and decoding capability. This allows operators to filter incoming signals and communicate within designated groups without interference from other conversations on the same frequency. This capability enhances clarity and reduces noise, making it an excellent choice for repeaters.

The HTX-400 also includes an Automatic Gain Control (AGC) feature, which adjusts the receiver automatically to varying signal strengths, ensuring consistent audio quality even in weak signal conditions.

Portability is a major consideration for amateur radio operators, and the compact size of the HTX-400 makes it easy to transport. It operates effectively with various power sources, including a standard AC power supply and battery, making it a suitable option for both home use and portable operations.

In conclusion, the Radio Shack HTX-400 is a versatile and reliable transceiver that features adjustable power output, user-friendly controls, memory functions, CTCSS tone capabilities, and excellent portability. Its combination of advanced technologies and practical design has made it a favorite among radio enthusiasts for decades.
