Question
What type of data is reported by amateur radio propagation reporting networks?
Answer Options
- A) Solar flux
- B) Electric field intensity
- C) Magnetic declination
- D) Digital-mode and CW signals
Correct Answer: D
Explanation
Amateur radio propagation reporting networks, such as the Weak Signal Propagation Reporter (WSPR) network, leverage the collaborative power of thousands of amateur stations globally to gather real-time data on band conditions. These networks are highly valuable because they report actual conditions, not just predicted indices.
These systems operate by having automated stations continuously transmit weak-signal reports. The receiving stations decode the messages and report the reception data, providing a real-time map of open paths. Therefore, the data reported by amateur radio propagation reporting networks is centered around the detection of Digital-mode and CW signals that confirm a working path exists between two locations.
