The maximum allowed duration for emergency frequencies is which of the following?

• A. 60 days
• B. 30 days
• C. 90 days
• D. 120 days

Answer: (A)

Emergency frequencies are a temporary, high-priority channel opened to support urgent communications when normal paths aren’t available. Because this use is temporary, there’s a defined, finite window for how long the frequency can remain allocated. This keeps the spectrum available for others and ensures a prompt reassessment, reversion to standard channels, or a formal reauthorization if the emergency continues. If more time is needed, you must pursue an extension through the proper authority with justification and coordination. Shorter durations would cause frequent renewals and administrative overhead, while longer ones could unnecessarily tie up the spectrum and create conflicts with other users. The idea being tested is that emergency frequencies are allowed only for a limited period, not indefinitely.
