MEMORY SCAN

Memory Scan scans all memory channels containing
data (All-channel Scan) or only a group of channels
specified by you (Group Scan). This type of scan
always ascends up through the channel numbers; the
direction of scan cannot be changed. While scanning, if
you want to skip over some programmed channels, turn
the M.CH/VFO.CH control. Pressing Mic [UP] or
[DWN] will also skip over channels but only during

All-channel Scan.

All-channel Scan or Group Scan can be selected via
Menu No. 66 (GRP.SCAN). The default is All-channel
Scan (OFF).
The following are additional important points regarding
the Memory Scan function:
Starting a transmission by closing the CW key, by
sending a packet, or by triggering the VOX circuit by
voice or the DRU-3 Digital Recording Unit stops
Memory Scan; however, transmission does not
begin immediately.
Starting the Memory Scan function switches OFF the
RIT and XIT functions. RIT and XIT are not
switched ON again when Memory Scan stops, and
the RIT/XIT offset frequency is not cleared.
Attempting to use Memory Scan when no data has
been programmed in any memory channels, or
when all channels are locked out, causes an alarm.
Scan will not start.
To scan channel 99, cancel Memory Channel
Lockout {page 62} for that channel.
Note:
Remember to adjust the squelch threshold level {page 19}
before using Memory Scan.

BUSY FREQUENCY STOP

The transceiver automatically stops Memory scanning
when a signal is detected if Busy Frequency Stop is ON.
The transceiver remains on the same channel for either
a short time or until the signal drops depending on
which Scan Resume method is selected (see below).
The squelch must be adjusted to the noise threshold
point with no signals present for Busy Frequency Stop
to work.
Toggle Busy Frequency Stop OFF or ON via Menu
No. 67 (BSY.STOP). The default is ON.
Busy Frequency Stop cannot be used with Program Scan.
Note:

Scan Resume Methods

Scan Resume controls when the transceiver
continues Memory scanning after stopping due to a
busy channel. Neither of the following two modes
function if Menu No. 67 (BSY.STOP) is switched
OFF. These modes cannot be used with Program
Scan.
Time-operated mode: After stopping, Scan checks
the busy channel approximately three seconds later.
If the channel is still busy, Scan waits another three
seconds then resumes scanning. If the channel is
not busy three seconds after stopping, Scan
resumes immediately.
Carrier-operated mode: Scan resumes
approximately two seconds after the signal drops.
Select your preferred Scan Resume method via
Menu No. 68 (CAR.SCAN). The default is
Time-operated (OFF).
ALL-CHANNEL SCAN
The All-channel Scan function scans all memory
channels containing frequency data.
1 Recall a Conventional memory channel.
2 Switch OFF Menu No. 66 (GRP.SCAN).
3 Adjust the SQL control while no signal is present.
The squelch must be closed before scanning
starts.
4 Press [SCAN] to start scanning.
5 To stop scanning, press [SCAN], or [CLR],
or [SEND], or Mic [PTT].
