D Single band/Dualwatch operation
Dualwatch operation monitors two frequencies simultane-
ously. The IC-2820H has two independent receiver circuits:
left band, and right band
ously. The IC-2820H has two independent receiver circuits:
left band, and right band
(available frequencies, operating mode
and functions are different depending on bands)
.
Single band operation is useful when only one frequency is
being watched.

(Right band’s)
to select the
signle band operation mode.
• Both left and right band’s [DIAL], [MAIN•BAND], [VOL], [SQL],
[V/MHz•SCAN] and [M/CALL•MW] can be used for operation.

D Diversity operation
The diversity receiving compares the receiving signal strength
from two different antennas, ANT1 and ANT2, and automati-
cally selects the strongest signal. This feature is useful when
you are listening in a moving vehicle or the transmitting sta-
tion itself is moving. Diversity receiving is available in
127 MHz, 136 MHz, 146 MHz, 375 MHz, 440 MHz and
500 MHz bands only.
