Q. Whatis 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.
2) Rotate the MAIN DIAL to select the desired amateur
band.
e To select the desired operating frequency, see (2)
OPERATING FREQUENCY SELECTION on the next
page.
e Band changes occur as shown in the following diagram.
[— These digits change.

be moved to any

GENERAL COVERAGE NOTE:

band (Gene) can be used between any amateur band.
The transceiver memorizes the previously used frequency
in the band stacking register cycle.
3) Push the [BAND] switch again to cancel the [BAND]
switch function.
