Icom tabletop receivers
The company Inoue Electric Factory Company Ltd. was founded in 1964 and got a reputation for it's solid state amateur radio equipment, initially operating in the VHF range.
After portable transceivers, Icom presented it's IC-R70 receiver in 1982. After gettings experience with the receiver circuitry of HF transceivers, Icom's first receiver R-70 was a quadruple conversion set which covered the range 100 kHz - 30 MHz. Due to its relationship to amateur radio equipment, this receiver had a operation schema which was a bit quirky, but with it's RF Notch and excellent passband tuning, set featured excellent post-processing especially of faint CW and radioteletype signals.
In 1984, this receiver was replaced by the IC-R71A, which allowed direct frequency entry via a numeric keypad, and an IR remote control was optionally available. Be careful when changing the back-up batteries of this receiver, after a loss of voltage, the set's ROM content gets lost and the radio must be sent to the manufacturer for reprogramming. The IC-R72 introduced in 1990 as a double conversion set in the lower price range was replaced in 1999 by the IC-R75 with DSP technology.
In addition, Icom offered a choice of wideband receivers, which could meet the highest demands and outshone the usual handheld scanners. After the IC-R7000, which similar dimensions like the IC-R71, the giant IC-R9000, which was equipped with a video monitor and could also display TV pictures and a spectrum analysis, followed as a high-end receiver. The product range was completed by several hand-held scanners.
Icom introduced a completely new receiver concept with the fully PC-controlled black-box receiver PCR-1000, which does not need a front panel and has almost no external controls, it's performance fits best into the scanner receiver range.
