General exam question G2B03
Subelement G2, OPERATING PROCEDURES· Group G2B
What is good amateur practice if propagation changes during a contact creating interference from other stations using the frequency?
- A.Advise the interfering stations that you are on the frequency and that you have priority
- B.Decrease power and continue to transmit
- C.Attempt to resolve the interference problem with the other stations in a mutually acceptable manner (correct answer)
- D.Switch to the opposite sideband
WhyGood amateur practice when propagation shifts create interference is to work out the problem with the other stations involved in a mutually acceptable way. Good amateur practice when a propagation shift creates mutual interference is to work it out cooperatively with the other stations involved, since nobody involved has a superior claim to the frequency, answer C. Claiming priority, simply powering down while continuing to transmit, or switching sidebands unilaterally don't actually resolve a shared-frequency conflict the way direct cooperation does.
