Inoue Electric Factory Company Ltd. founded in 1964 got a good reputation fo their Amateur radio and transistorized VHF gear.
After some portable transceivers, Icom presented the IC R-70 in 1982, a quadruple conversion receiver covering 100 kHz - 30 MHz. Operation of this set is very similar to the operation of the receiver part found in Icom Ham transceivers in those years, not really straightforward - but the excellent passband tuning and notch and the superior stability made this set a good choice for CW and RTTY operation. The IC R-71A followed in 1984 and featured direct keypad frequency entry, it's major drawback is, that the set has to be sent back to the manufacturer for a ROM update, once the internal backup battery has to be replaced - this set won't even remember that it is a shortwave receiver after it has lost it's ROM content.
The low-end shortwave receiver IC R-72 introduced in 1990 and the IC R-75 with DSP facilities offer very reliable shortwave reception.
In addition, Icom has a range of wideband or scanning receivers, from the IC R-7000 with a similar design as the R-71, to the huge R-9000 with a screen that could even display television contents and could be used for spectrum analysis. There also have been several small portable wideband scanners, sized like the shirt-pocket VHF/UHV transceivers.
The Icom PCR-1000 was Icom's first fully computer-controlled "blackbox" receiver, this set without frontpanel controls has to be controlled by a notebook computer.
