MHz
~
28
MHz
for transmitting
and
has receive capability
from
500 kHz
~
30 MHz. The
IC-725
has
a
convenient

Q.
What
is
the function of the
band
stacking
register?
A.
The
band
stacking register stores
operating
fre-
quencies
in
VFO
modes,
switches bands,
and
returns the transceiver
to stored
frequencies.
This
is
especially
convenient
when
switching bands
during contests
and
for
quick monitoring
of pro-
pagation conditions
on
other bands.
