Maintaining Communication

When making contact with other station, I usually ask about my signal report. This is the first important thing to know before making futher transmission.

For voice operation simply the readability and signal strength report. But for CW operation are readability, signal strength and tone.

Sometimes receiver station gave 59 plus 10db. When operating using limited power source, I usually reduce my power enough for maintaining communication only. 59 report is enough, 55 report also ok but if my signal is fading, ill increase my transmission power.

Report may vary from time to time, from place to place. Sun moves from east to west giving effect to ionosphere. Sun itself have its own activities.

Most of high frequencies will get better condition on the night than day.

To maintain communication, we need to know our transceiver technical spec. For example, How much current will our rig drains our battery while receiving or transmitting?
