■ Selecting a receive mode
What are receive modes?
Radio signals can be propagated in a variety of ways (or
modes). Each mode has its own physical properties that de-
termine to some degree its uses.
The IC-R10 receives the 6 most common modes: AM, FM,
WFM, USB, LSB and CW. When you want to tune a station,
you MUST set the receive mode first. The table below shows
common uses for each mode.
