E. Memory shift
This feature shifts the memory channel data to the
VFO. This will allow you to alter the frequency or
mode without changing the contents of the memory
channel. ''MR'' disappears from the display panel
and ''A"' or ''B'' (The VFO used before the memory
channel operation was started) appears. Press the
MR key to return to the memory channel.
4-2-5. Mode selection
A. Manual mode selection
Most operations can be performed in the AUTO
mode. In the following operations, you must select
the appropriate mode using the FM/LSB and
USB/CW keys (when any of these keys is pressed,
the AUTO mode is released):
{a) TX QSY (Change frequency while transmitting)
for satellite communication or other applica-
tions.
{b}) Memory channel mode scan.

B. AUTO mode
The AUTO mode function automatically sets the
mode to correspond to the selected frequency as
shown below, which is especially convenient for
mobile operations.
Note: -
During transmission in the AUTO mode, TX QSY is
disabled. To switch frequencies while transmitting
for satellite communication or other similar applica-
tions, select USB, LSB or CW.

In the SSB and CW modes, the AGC circuit
minimizes the variation in the sound output caused
by variations in the incoming receive signal strength.
The AGC time constant is automatically set by mode
as follows:
