Deep Dive: E2E06
The correct answer is C: 15 seconds. What is the length of an FT8 transmission cycle is 15 seconds. FT8 uses 15-second cycles for transmit/receive. For amateur radio operators, this is important for FT8 operation. Understanding this helps when operating FT8.
Why Other Answers Are Wrong
Option A: Incorrect. It doesn't vary with amount of data - FT8 cycles are fixed at 15 seconds. Variable isn't correct. Option B (8 seconds): Incorrect. 8 seconds isn't the cycle length - FT8 uses 15-second cycles. 8 seconds is wrong. Option D (30 seconds): Incorrect. 30 seconds isn't the cycle length - FT8 uses 15-second cycles. 30 seconds is wrong.
Exam Tip
FT8 transmission cycle = 15 seconds. Think 'F'T'8' = '1'5 seconds. FT8 uses 15-second cycles for transmit/receive. Not variable, not 8 seconds, not 30 seconds - just 15 seconds.
Memory Aid
FT8 transmission cycle = 15 seconds. Think 'F'T'8' = '1'5 seconds. FT8 uses 15-second cycles for transmit/receive. Important for FT8 operation.
Real-World Example
An FT8 transmission cycle: It's 15 seconds long. FT8 operates on fixed 15-second cycles - stations transmit and receive in synchronized 15-second periods. This is the cycle length - 15 seconds for FT8.
