Deep Dive: E3C09
The correct answer is D: Digital-mode and CW signals. What type of data is reported by amateur radio propagation reporting networks is digital-mode and CW signals. Propagation networks report reception of digital and CW signals. For amateur radio operators, this is important for understanding propagation reporting. Understanding this helps when using propagation data.
Why Other Answers Are Wrong
Option A (Solar flux): Incorrect. Solar flux isn't reported by amateur networks - amateur networks report signal reception. Solar flux isn't the data. Option B (Electric field intensity): Incorrect. Electric field intensity isn't reported - amateur networks report signal reception. Electric field isn't the data. Option C (Magnetic declination): Incorrect. Magnetic declination isn't reported - amateur networks report signal reception. Magnetic declination isn't the data.
Exam Tip
Amateur propagation networks report = digital-mode and CW signals. Think 'A'mateur 'P'ropagation = 'A'mateur 'P'articipants report signals. Propagation networks report reception of digital and CW signals. Not solar flux, not electric field, not magnetic declination - just digital/CW signals.
Memory Aid
Amateur propagation networks report = digital-mode and CW signals. Think 'A'mateur 'P'ropagation = 'S'ignal 'R'eception. Propagation networks report reception of digital and CW signals. Important for understanding propagation reporting.
Real-World Example
Amateur radio propagation reporting networks: They report digital-mode and CW signals. These networks collect data from amateur operators about which signals they're receiving, providing real-time propagation information. This is the data - digital-mode and CW signals are reported.
