5. Start the scanning process with the soft-key

(the bullet will be filled when scan is running). The

memory channel currently being monitored is shown

above the Scan legend. Press

again if you

want to stop the scan.

The squelch threshold can be adjusted for each of the

memories (if necessary) during this first scan pass. When

the squelch level is changed the new value will

automatically be stored in the memory channel whilst the

scan is active. Also the scan delay timer is re-started when

the spin-wheel is turned so you have longer than 5 seconds

to make the adjustment.

The squelch level should be set so that the reversed S

squelch indicator is shown when there is only noise present

on a particular memory channel. The setting should be as

low as possible so that any signal will exceed the squelch

level and pause the scan.

Note: If you change the squelch level when the scan is

not running then the data in the memory will not be updated

automatically. In this case, to update the squelch data in

the memory return to the MEMORY menu (use the

soft-key) and then store the new settings (use the

soft-key). The complete key sequence for this is

To manually advance the scan to the next channel press

TWICE.

The scan delay can be adjusted whilst the scan is running.

Go to the SCAN SETUP menu (use the

soft-key)

and use the spin-wheel to change the delay time. The

scan will automatically stop if you try to change the block

start and end channels, or if you select a non-scanning

menu.

8-5 Memory technical details

Data is stored in the AR7030 in a number of different

ways, using RAM maintained by an internal rechargeable

and an EEPROM. The memory holds information relating

to the receiver’s alignment and filter setup, default setup,

three additional user definable setups, VFO-A status, 100

memory channels and clock.

Generally speaking, memory is split into four sections:-

a. Power-down memory:

stores general settings while the receiver is

switched off.

b. Setup memories (3):

store particular configurations of settings.

c. Frequency memories (100):

store frequency and associated information.

d. Background VFO (VFO-B):

stores complete receiver status, but data is not

held when power is removed from the receiver.

a. Power-down memory. With default settings

(shown in brackets).

Contains:-

Tuned frequency and mode.

IF bandwidth for each mode.

Passband shift for each mode.

BFO setting for CW and DATA modes.

AGC speed for each mode.

IF gain and RF gain (Max, 0dB).

Volume, Treble and Bass.

Squelch level and muting (Min, On).

Scan start and stop channels (1, 10).

Scan delay time and hold mode (5s, Off).

Timer start and run times.

Frequency lock (Off).

Aux output level.

IR remote tuning step size.

b. Setup memories (3 memories: A, B and C).

With default settings (shown in brackets).

Contains:-

IF bandwidth for each mode (2.2kHz, 5.5kHz).

Passband shift for each mode (Zero).

RF gain (0dB).

BFO setting for CW mode (800Hz).

BFO setting for DATA mode (1.35kHz).

AGC speed for each mode (Med, Slow).

Squelch muting and scan hold (On, Off).

Treble and Bass (Flat).

Aux output level (Max).

IR remote tuning step size (1kHz).

c. Frequency memories (100 memories: 0 to 99).

Contains:-

Tuned frequency and mode.

IF bandwidth and passband shift.

Squelch setting for AM, NFM and SSB modes.

BFO setting for CW and DATA modes.

Scan include / exclude.

d. Background VFO (VFO-B)

(not stored at power-down).

Contains:-

Tuned frequency and mode.

IF bandwidth and passband shift.

IF gain, RF gain and AGC speed.

Volume, treble and Bass.

Squelch level.

BFO setting.

Scan delay time and hold mode.

IR remote tuning step size.
