The K.W, 202 Receiver has been designed far optimum performance on SINGLE SIDEBAND SUPPRESSED CARRIER, with excellent results on C.W. and A.M. It operates on all Amateur Bands between 1.8 MHz and 30 MHz. The Receiver employs thirteen valves in a double-conversion superhet circuit, plus 12 diodes and one transistor. The K.W. 202 has a built-in power unit operating from a 105 - 120, 210 - 240v, 45-65 Hz AC Supply. A two-speed V.F.O drive is used to rotate the scale which is calibrated 0-500 KHz, and can be re-set for optimum read out accuracy. A plug-in CRYSTAL CALIBRATOR provides marker signals every 100 KHz for checking the dial calibration accuracy; (This is available as an optional extra). A built-in Q-MULTIPLIER improves the selectivity for CW operation, and has a NOTCH facility for rejecting unwanted heterodynes and certain interfering signals.
