Abstract

Upon the selection of a desired reception channel, the tuner oscillator (9) is switched off, while an oscillator (15) simulating reception signals is switched on at the antenna input and is switched alternatingly on at least two frequencies within the reception channel. A R.F. signal demodulator (16) provides to a microprocessor (13) a criterion to indicate an optimum tuning. The obtained tuning voltage is conducted to the R.F. circles (3-5) to be adjusted after digital/analogue transformation (18-20), up to the end of the adjustment of all circles.
