Receive Mode Selection; Lock Function - Icom IC-R20 Instruction Manual

■ Receive mode selection

Receive modes are determined by the physical properties of
the radio signals. The receiver has 6 receive modes: FM,
WFM, AM, LSB, USB and CW modes. The mode selection is
stored independently in each band and memory channels.
Typically, AM mode is used for the AM broadcast stations
(0.495–1.620 MHz) and VHF air band (118–135.995 MHz),
and WFM is used for FM broadcast stations (76–107.9 MHz).
➥ Push [MODE SCAN] momentarily several times to select
