ARRL Technician Practice Exam 2026 – The All-in-One Resource to Master Your Certification!

The frequency 443.350 MHz is approved for use by Technician Class license holders operating within ITU Region 2, which includes North America and parts of South America. This frequency falls within the 70 cm band (430-440 MHz), where Technicians have access, specifically to the subband from 420 to 450 MHz.

Technician Class licensees are allowed to operate on 70 cm frequencies, but it's important to note that certain allocations are exclusive to higher license classes, and a thorough understanding of band plans ensures compliance with these regulations. The 433.500 MHz frequency, while used in some countries, is not allocated for Technician use in Region 2. The same goes for 425.150 MHz, as it falls outside the generally available spectrum for Technician licensees in the United States. While 444.000 MHz is indeed a common frequency within the Technician band, 443.350 MHz is chosen here as it is a recognized frequency for non-repeater use as well.

In summary, knowing the specific frequencies that are authorized is essential for compliance and effective operation within the amateur radio service, as well as for leveraging the capabilities of the Technician Class license.
