■ Dualwatch operation

Dualwatch monitors 2 frequencies simultaneously.

The IC-7800 has 2 independent receiver circuits to

allow you to a dualwatch even in different frequency

band and mode.

q Set the desired frequency and mode into the main

band.

w Push [DUALWATCH].

• “ ” appears.

• Pushing [DUALWATCH] for 1 sec., the sub band is

equalized at the same time. This quick dualwatch func-

tion can be turned OFF in set mode. (p. 12-13)

e Rotate the sub dial to set the desired frequency.

r Push [SUB] to enables the sub band access when

changing the frequency band, operating mode, etc.

in sub band.

• Push [MAIN] for the main band access.

t Rotate [AF] for sub band to adjust the sub band

audio level.

y To transmit on the sub band readout, push

[CHANGE] or [SPLIT].

NOTE:

• Beat may be sound according to the set frequen-

cy combination, such as 3.5 MHz and 7 MHz

band’s frequencies.

• Receiver sensitivity will be decreased when the

same frequency band and the same antenna are

selected during dualwatch.

• The RIT function can be used for the main read-

out only.

• The ∂TX function can be used for the transmit

readout (main readout when the split function

OFF; sub readout when the split function ON).
