As a result, the receiver 11 receives the broadcast station having the auto store number input from the input means 16.
- the main control means 24 refers to the broadcast station data table via the memory control means 24, and the reception frequency setting means uses the broadcast station frequency of auto store number 1 as the reception frequency. 21 can be set to receiver 11!
- the priority country code may be set based on the vehicle registration country information. May prescribe the country code with the highest number of broadcast stations stored in the preset station as the preferred country code.
- the country indicated by the vehicle position information obtained by the GPS system that is, the country where the vehicle is located may be set as the priority country code.
- the non-priority country broadcasting station data is stored in the final memory if the capacity of the final memory is excessive. Since the broadcast station data table is generated by memorization, there are few auto-stored broadcast stations that can be tuned if there is an effect that the final memory can always be used effectively. If the situation can be avoided, there will be an effect.
- the priority country broadcast station data and the non-priority country broadcast station data are stored in order of the received electric field strength. There is an effect that it can be received in advance.
- the broadcast signal power country code is detected only when the received electric field intensity detected by the electric field intensity detecting means 22 exceeds a predetermined value. This has the effect that only the country codes can be selected.
- the priority country broadcast station data is stored in the first memory in the descending order of the reception electric field strength
- the non-priority country broadcast station data is stored in the order of the high reception electric field strength. Since the priority country broadcasting station data and the non-priority country broadcasting station data stored in the first and second memories are rearranged and stored in the final memory as the broadcasting station data table. Therefore, it is possible to easily perform storage processing for storing non-priority country broadcasting station data after priority country broadcasting station data.
- the receiving apparatus is a receiving apparatus that can always perform channel selection using the auto store function by effectively using the auto store memory. Suitable for use in etc.
