Should the Collins SSB filter be fitted and the receiver's
microprocessor reset you must hold the [3] key while resetting via the
bottom case reset switch. This action alters the carrier re-insertion
point to optimise the SSB filter's characteristics.
To “fully optimise” the Collins SSB filter performance, the carrier
crystals may be replaced at a small additional charge.
3. BFO in CW mode.
The BFO is permanently engaged in the CW mode (page 29 section
6-10).
4. Collins filter identifying numbers.
Two filters of identical specification are used in the receiver as listed
below:
AM filter 526 8636 010 or 526 8695 010
SSB filter (option) 526 8635 010 or 526 8694 010
CW filter (option) 526 8634 010 or 526 8693 010
5. Collins label.
The red Collins Inside label on the top case is of a reusable
design. We acknowledge that such a label may not be to
everyone's taste so have chosen a non-adhesive design.
Should you wish to remove it, simply peel the label off.
6. Carton box.
Despite the carton box being durable, it is of a basic design.
The cardboard carton has been intentionally chosen for
environmental reasons being degradable... unlike traditional
polystyrene.
7. Audio quality on AM
The AR3030 has been designed to provide the very best
selectivity for shortwave broadcast listening. Should you
listen to strong signals such as Radio 4 (198 kHz), more
treble may be produced by moving the passband.
Off-tune the receiver by 1 kHz UP or DOWN and reassess
the audio. Of course this technique cannot be used for
synchronous AM listening (S.AM).
Due to the excellent stability offered by the Temperature
Compensated Crystal Oscillator (TCXO), it is possible to listen to
AM broadcasts while in the USB and LSB modes. This can be very
useful for removing adjacent interference which is affecting one side
of the AM signal only.
8. REMOTE RS232C
To place the AR3030 into RS232C control mode, the
initialisation key sequence must first be keyed in
through the keypad (not via the RS232 port).
