Operating with Courtesy and Clarity

Learn how to share the radio spectrum fairly by listening first and adjusting your power. Discover practical methods to test equipment and join nets without causing interference.

This lesson is part of SignalPrep Pro. The subsection's 11 exam questions are free to practise: practise B-002-004.

What this subsection asks

• What should you do before you transmit on any frequency?
• If you contact another station and your signal is extremely strong and perfectly readable, what adjustment should you make to your transmitter?
• You need to transmit to adjust your antenna tuner prior to joining an HF single-sideband net that is in progress. On what frequency should you make the adjustment?
• How can on-the-air interference be minimized during lengthy transmitter testing?
• Why would you use a dummy load?
• If you are the net control station of a daily HF net, what should you do if the frequency on which you normally meet is in use just before the net begins?
• If a net is about to begin on a frequency that you and another station are using, what should you do?
• If propagation changes during your contact and you notice increasing interference from other stations on the same frequency, what should you do?
• When selecting a single-sideband voice transmitting frequency, what minimum frequency separation from a contact in progress should you allow to minimize interference?
• What is a band plan?
• Before transmitting, the first thing you should do is:
