AOR Ltd, Tokyo
The Japanese company AOR was originally known for its scanner receivers, but they launched some remarkable shortwave receivers in the nineties.
The Japanese radio amateurs Takano (JA1AOR) and Oshima (JA1EXM) founded the company AOR Ltd in 1977. The breakthrough was in 1984 with the introduction of the wideband scanner AR2001. At the end of the 1980s, the company launched the AR2515 and AR3000(A) scanner receivers in a console tabletop cabinet, which covered the frequency range from 100 kHz to 1.5 or 2 GHz, and thus also shortwave.
The AR3030 was the first pure shortwave receiver, a double conversion superhet covering 30 kHz - 30 MHz, it was also offered in a special veriant with a mechanical Collins filter.
The successor AR5000 was a wideband receiver covering the frequency spectrum from 10 kHz to 2.6 GHz and was in an improved version also equipped with a noise blanker and synchronous detector. In cooperation with a British development team around John Thorpe, the AR7030 appeared in 1996: this very compact tabletop receiver had a reception performance reaching into the semi-professional range, although many of the features can only be used with the remote control.
Another development was the series of handheld scanner receivers with a design reminiscent of handheld walky-talkies. After 1990, the AR1000 / AR2000 and later the AR8200 were milestones in this field.
With the compact AR8600 and AR ONE, again tabletop receivers were launched under the brand name AOR.
