General exam question G3B04
Subelement G3, RADIO WAVE PROPAGATION· Group G3B
Which of the following is a way to determine current propagation on a desired band from your station?
- A.Use a network of automated receiving stations on the internet to see where your transmissions are being received (correct answer)
- B.Check the A-index
- C.Send a series of dots and listen for echoes
- D.All these choices are correct
WhyChecking a network of automated internet-connected receiving stations to see where your own transmissions are being heard is a way to determine current propagation on a desired band. Checking a network of automated internet-connected receiving stations to see where your own signal is actually being heard is a direct, real-time way to gauge current propagation on a band, answer A. The A-index reflects geomagnetic conditions generally, not band-specific propagation from your particular station, and sending dots and listening for echoes isn't a real propagation-checking technique amateurs use.
