AR3030 operating manual 12 This quarter inch socket is located on the top left hand side of the front cabinet directly underneath the power switch. A pair of headphones or earphone may be connected with an impedance of 8 OHMS or greater. When this headphone socket is used, the internal speaker and any external speaker will be automatically disconnected. 5-3 Mode keys and indicators There are two mode keys on the front panel located between the S-meter and LCD, there are also seven LED indicators to...

5-6 SCAN key
The SCAN key is used to start the memory scan facility which will cause the
receiver to check the occupied channels of it’s memory content for activity
(busy channels).
SCAN can only be selected if the AR3030 is in VFO mode.
It is possible to select all memory channels to be
scanned or just a specified range of memory channels.

The attenuator facility can be useful for reducing the level of unwanted strong
signals or “overload”. The AR3030 has three settings of attenuator (ATT),
these being 0dB (no indication on the LCD - normal setting), -10dB “[10dB]”
indicated and -20dB “[20dB]” indicated.
The AR3030 does not contain RF amplification prior to the band-pass filters,
all gain is applied in the more selective IF stages. This ensures the highest
immunity to intermodulation effects sometimes caused by...](http://img.usermanuals.tech/thumb/5671/81680/w300_aor_ar3030-hf-comms-reciever_manual-1_d-14.png "Page 15

required
i.e. while in VFO mode [4] [.] [7] [2] [2] [MHz]
While in VFO mode, this key alters selection of tuning rate to MHz. An
underscore “[ _ ]” indicates the selection of MHz tuning speed on the LCD.
Note: Frequencies below 1.8 MHz are treated as kHz. For this reason
1 MHz cannot be selected using the [MHz] key in conjunction with
the rotary tuning control.

rotated fully anti-clockwise the volume is reduced to minimum.

AR3030 operating manual 18 If the control is rotated too far clockwise then weaker signals will be totally lost and only local strong signals will be heard. 5-23 RF GAIN control This small rotary tuning control is located on the front panel underneath the BFO PITCH control. The RF GAIN control reduces the level of amplification applied to the receiver’s I.F. circuits. This has the effect of reducing the sensitivity of the receiver in much the same way as the attenuator but is more controllable. The...
