AR-One description :

The AR-One is a compact desktop receiver, and therefore also suitable for vehicle use. The apparatus is mainly aimed at listeners who wish monitoring over a wide range of frequencies but which do not require articulated signal control functions. The front panel over the tune control is developed with a limited set of buttons and only two knobs. For this aspect it basically proposes an interface similar to that found in a portable scanner.

Other features: selection of different IF filter bandwidths for FM, high frequency stability, input for a standard frequency reference, IF output, adjustable BFO, squelch, S-meter on LCD display even directly in uV. Multiple search options and a wide range of general memories with 10 independent VFOs. RS-232C connection (two ports) for PC control up to 99 receiving units.

AR-One performance and practical notes :

This receiver is characterized by an unsatisfactory price / performance ratio. For this reason it is mainly due the limited diffusion of the AR-One among the fans. This factor naturally changes in value when turning to the used market if you have the opportunity to find a proposed model at a reasonable cost. Generally speaking, the receiver offers a wide coverage of frequencies to the benefit of operators looking for a small size scanner, certainly superior to handheld in performance. But at the same time those who practice a demanding radio-listening find handicaps especially below 30 MHz for the lack of functions like PBT and notch-filter as well as for a not excellent front-end dynamic. In contrast, on VHF / UHF the availability of multiple bandwidths for FM mode adds considerable flexibility of use that is appreciated both in FM-DX on the broadcast portion of 87.5 ~ 108 MHz and in the reception of WEFAX satellite signals (weather data), or again in the acquisition of FSK data flows typical of telemetry emissions. In this context, the possibility of further processing starting from the IF signal, made at the output through a connector on the rear panel, is an element to underline.
