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.
