The AR3030 offers the very latest technology through use of its’ DDS (Direct Digital Synthesizer). The legendary Collins 6kHz AM filter is fitted as standard to provide the highest levels of AM selectivity. High stability is accomplished by the standard fitting of a TCXO (Temperature Compensated Crystal Oscillator). As the model name would suggest, the tunable coverage is 30kHz - 30 MHz (with 29.999995 MHz being the actual upper limit of tuning) using silky-smooth 5Hz steps. The AR3030 offers all mode operation as standard: AM, S.AM (double side band synchronous), USB, LSB, CW, FAX & FM. All necessary information relating to frequency, filter setting etc is presented via a highly visible switchable backlit custom LCD. Mode selection is displayed via a series of LEDs. Although 5Hz tuning steps are available in all modes coupled to true automatic carrier insertion in USB, LSB, FAX & CW, a separate BFO control is selectable in USB, LSB, FAX & CW to provide even greater flexibility producing a manual form of pass band tuning. While in any receive mode it is possible to increase the tuning steps from five Hz (display resolution 10Hz) to hundreds of Hz and kHz by pressing the kHz key while in VFO mode. Selection of MHz tuning may also be accomplished in VFO mode by pressing the MHz key. The position of the underscore character “_” indicates selected tuning rate. A smooth action rotary tuning control with a finger-tip-hollow is provided to ensure a high level of operating pleasure, convenience and versatility. Frequencies may be entered directly via the numeric keypad, great versatility is provided by careful attention to firmware programming. Frequencies may be entered as kHz i.e. [6] [0] [9] [0] [kHz], MHz i.e. [6] [.] [0] [9] [0] [MHz] or the “band” may be selected i.e. [4] [9] [mtr] returns to the last frequency used on that band, probably no other receiver offers such convenience. All broadcast bands are recognised as well as region 1,2 & 3 Amateur bands... i.e. 80, 75, 49m etc. Twin VFOs retain all necessary information such as frequency, mode, I.F. bandwidth, audio filter, attenuator setting and tuning step size and BFO status On/Off. 100 memories also hold the full range of settings making transfer to and from memory straight forward and very convenient.
