Description :

With the ATS-909X receiver the Sangean has renewed, in style and partially in features, its popular portable ATS-909 among the most appreciated within its category. This new version adopts a similar circuit with a set of well positioned commands and a double conversion system that expresses a good sensitivity and an equally valid rejection to the image frequencies. The coverage is continuous for long, medium and short waves in AM as in SSB maintaining for the entire spectrum a significant resistance to intermodulation. For the FM band the display shows the multi-code information of the RDS system, an important aspect for the FM-DX fans. 406 memories are available to record favorite stations, even through an automatic frequency scan. Each memory can be identified by a label composed of up to 8 characters, in the case of the locations for the SW band the label is to distinguish an entire bank of memories.

Other features: narrow or wide selectivity, local or DX sensitivity, continuously adjustable attenuator (in 0.1 - 30 MHz), squelch, three audio tone profiles, direct frequency setting from the keypad, clock, alarm, sleep-timer, internal ferrite antenna for LW / MW bands and extractable stylus for SW / FM, external antenna connector, alkaline or rechargeable battery compatibility, integrated battery charger, battery status indicator, control connections for an audio recorder.

Performance and practical notes :

Undoubtedly the ATS 909X is an interesting apparatus. At a superficial glance it has renewed only the aesthetics of its predecessor, it is now slightly smaller and with a style of greater appeal, but the variations are also substantial. To start the sensitivity, it proves to be better on the SW, making it practical to use the radio in combination with the supplied antenna. Then there is the SQUELCH control which gives the possibility of adjusting the reception threshold to eliminate noise and weak signals, an option not normally available in the world receiver although its setting is not particularly easy. Another innovation is the RDS which displays the station name, type of programming, etc., for the codes PS / PTY / RT. An expansion compared to the standard RDS display. Also with the RDS, if the station transmits the CT code, it is possible to synchronize the 909X clock with this time reference. Thanks to the Aux-in connection, it is now possible to connect an external audio source such as an iPOD, MP3 or CD player. The presence of a battery charger with a selection of NiMH / NiCad batteries proves to be very convenient. Finally the case, its plastic container, which is made available in two colors, light or dark, to suit the buyer's preferences.
