Single Band Operation - Icom IC-R2500 Instruction Manual

■ Single band operation

D D Single band/Dualwatch operation
Dualwatch operation monitors two frequencies simultane-
ously. The IC-R2500 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. The right band can be inhibited.
q Select the left band as the main band.
➥ Push [MAIN•AGC] once to select left band, if necessary.
w Push [SET•SKIP] to enter set mode.
ePush [SET•SKIP] or [ATT•PRIO] several times to select

When the dualwatch operation is in use, IC-R2500 must be
connected to two antennas. ([ANT1] and [ANT2])
D 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 from 50
MHz to 1300 MHz on FM, P25 and DV modes only.
