Features:
The small gray machines occupy your briefcase 225 * 132 * 35 mm of space. The front panel of the machine than most portable confidential, but compared to, but very thin. The aircraft used four batteries, the battery on the back of the battery compartment. According to the voice and the band you choose, the machine consumes about 250 mA. Of course, the main power will be cheaper, you can use an intelligent dual-voltage power adapter. At least in Europe they are bundling. It will automatically detect the voltage of 220V or 110V, and automatically adapt. The machine contains a battery is 874 grams.

Frequency Range:
The front panel by a green LCD screen, by means of its backlight, and you use in the dark room is also no problem. The frequency of the aircraft’s continuous coverage from 150 kHz to 29999 kHz, another FM from 87.5 MHz to 108 MHz.

Mountain into a very practical function of ATS, automatic tuning system. When you arrive in a strange city and do not know the frequency of the local radio station, as long as you press the “FM” button a few seconds, the radio will automatically search and store the 18 strongest stations, you simply press the corresponding function key To listen to the radio. MW band also has this feature, you can only store up to nine stations in the LW band. This is a very useful feature. Of course, in the SW, and not have this feature, because the short-wave signals are the same everywhere.

Aircraft traditional tuning, “” “” tuning keys and a two-speed for the conventional manual tuning of the tuning knob. You can press the “on” button to start automatic search until the search to a clear radio. There is also a well-designed page for the concept of storage systems. Not only can you store frequency, and the ATS-909, can also record radio is the AM, the upper sideband or lower sideband, it also provides the receive mode of the three.

If you have patience, you can store up to 261 shortwave radio station name and frequency, of which 18 MW and FM, LM9 one. Fortunately, the aircraft has been completely built-in frequency of 29 radio stations, some stations such as the Deutsche Welle, on BBC World Service, Radio Netherlands, the Voice of America, Radio Vlaanderen International and Radio Japan. Of course, these frequencies can be changed, you can upgrade these. You need to use the tuning knob and the “” key to enter the data.

It should be noted that the storage location from 212-261 are preset and can not be changed in the Radio Shack DX-398 instructions. We examined this point, the description is incorrect. If necessary, the frequency and name of the preset can be changed.

ROS system:
The machine is one of the portable radio of the RDS (data broadcasting system) function in the FM band in Europe a few. If your country is using this system, then the RDS system to receive and demodulate the information sent with the broadcast signal. The name of the station will be displayed on the screen after a few seconds, but this feature requires a strong signal support. You also may be noted that some stations are using the ROS system to publish the weather and business information.
In some countries, among the signal with time signal of ROS can also provide time information ATS-909 can use it to correct the time. You can also use the aircraft built in 42 cities in the world time, and you wish to add the time you need. The aircraft can be identified in some countries up to half an hour between the time interval. The machine has a precision clock system, you can set three different times, using three different radio to wake you. Taken together, all these features are deliberate.

Performance:
Have sufficient sensitivity in all bands. In many remote areas of Australia, scalable cool clothesline “antenna can receive a weak signal. In Europe, the signal is too strong can adjust the radio side of the RF gain control knob to weaken sensitivity. You can not adjust the sensitivity of the FM band, but its sensitivity is just suitable for the suburbs.

Tuning in terms of progress in the SW, can be set to 1 kHz or 5 kHz, in the MW band to 1 kHz, 9 kHz or 10 kHz, LW, 1 kHz or 9 kHz, the FM band, you can at 100 kHz and choose between 50 kHz.

In the dynamic selection, the machine has two filters, broadband and narrowband filters. Their performance is very balanced, and broadband is set to 6.5 kHz @ – 6 dB, the most suitable in the MW and SW strong signal, switch to narrowband 4 kHz location of radio station other than the 5 kHz will reduce adjacent channel interference, but frankly said narrow-band filter this should be able to provide a more narrow filter performance. Indeed, compared with some of the classic top-level portable machine, which is a drawback, but the better the filter will increase the price.

Some of the synchronous detection on the radio in this price. Can lock those radio receiver broadcast carrier, and can compensate for the attenuation and the corresponding sound distortion, always shortwave receiver. The ATS-909 does not provide synchronous detection function, it is clear, with research and development costs in other areas, such as the RDS system.

We really liked its sound quality, 7 cm speaker is crisp and there are three sound selector switch.

ATS-909 portable shortwave market, very popular. The machine attractive features is the tuning convenience.

In 1996, based in Amsterdam, World Radio TV Handbook granted to the aircraft of the ’96 / ’97 the year the honor of the world’s best portable shortwave radio.
