Kenwood / Trio - Kenwood Communications, Tokyo
QR - 666
überarbeitet am 21.10.2010
As a successor for the quite successful 9R-59DS, Trio-Kenwood presented it's solid state QR-666 all wave receiver with continuous coverage from mediumwaves through 30 MHz and an optional FM tuner around 1975.
The Trio - Kenwood QR-666 is a completely solid state all wave receiver, with it's
dimensions of 360 x 165 x 280 mm and it's weight of 7,3 kg, it is a medium sized
desktop receiver slightly bigger then Kenwood's R-1000.
In the middle of the front panel, You find the two characteristic orange - yellow backlit
drum dials. The upper one is the main tuning dial with it's tuning knob, below, You
find the bandspread tuning dial with calibration marks for the amateur bands.
At the rear of the set, You find connectors for a long wire antenna and a coaxial SO-239 antenna socket as well as the mains and 13,8 V DC connectors. You can control the calibration of the signal strength meter and access some components for alignment of the set from it's top cover.
At the right side of the cabinet, my set has a big rotary knob numbered from 88 - 108, it's the tuning and dial knob for the optional FM tuner. Like in the Barlow Wadley XCR-30, the engineers added an optional FM tuner to let You to listen to Your favourite local FM broadcaster, Sony's ICF-6800W has a rudimentary FM reception capability, too.
Operating the QR-666 is quite straighforward: Switch the set on using the POWER pushbutton, turn the RF gain fully clockwise and the AF gain until You hear a slight noise. To receive "Deutsche Welle" on 6075 kHz, use mode AM, band segment D und use the main tuning knob to find the signal from Cologne somewhere between the 6,0 and 6,1 marks. Use the fine tuning control to adjust for maximum readibility and tweak the antenna trimmer for maximum signal strength.
In conclusion, Kenwood's QR-666 receiver is a simple all wave and amateur band
receiver. You can use it for listening to the major international broadcasters
signals and for monitoring some amateur radio traffic in CW and SSB modes. Without
electronic memories and with it's only rudimentary dial calibration, I would rather
recommend a set with digital frequency display for Your first steps on the shortwaves.
