1. A method of supplying a control signal for controlling a radio receiver after a change in location, comprising the steps of:
- evaluating a check-back transmit frequency for determining whether the check-back transmit frequency is of a reception quality;
storing the check-back transmit frequency in the radio receiver if it is determined that the check-back transmit frequency is of the reception quality;
comparing the reception quality of the stored check-back transmit frequency with a reception quality of a set non-check-back transmit frequency;
replacing the stored check-back transmit frequency with the non-check-back transmit frequency if the reception quality of the non-check-back transmit frequency is greater by a first predetermined value than the reception quality of the stored check-back transmit frequency;
incrementing a count by a second predetermined value at a predetermined interval;
reducing the count by a predetermined factor when the stored check-back transmit frequency is replaced by the non-check-back transmit frequency; and
supplying the control signal as a function of the count.

Abstract
A method of supplying a control signal for controlling a radio receiver after a change in location. Four check-back transmit frequencies are stored in the radio receiver. The control signal is supplied by a counter whose count is increased regularly or is reduced by a factor when there is a change in the check-back transmit frequencies.

7. A radio receiver for supplying a control signal after a change in location of the radio receiver, the control signal containing information with respect to the change in location, the radio receiver comprising:
-
a first memory for storing check-back transmit frequencies; a second memory for storing at least one value indicative of a reception quality of the check-back transmit frequencies stored in the first memory; a counter for generating a count-dependent output signal; and a microprocessor for supplying the control signal and containing a subprogram for controlling the count-dependent output signal as a function of a change in a status of the check-back transmit frequencies, wherein; the counter is capable of being incremented by a first predetermined value at a predetermined interval, and the counter is capable of being decremented by a predetermined factor when one of the stored check-back transmit frequencies is replaced by a non-check-back transmit frequency.
