Automatic radio check monitoring and adaptive transmitting system
First Claim
1. A method for automatically providing radio checks to vehicle radios, the method comprising:
- broadcasting on a predetermined radio frequency a selectable radio check option from a fixed station;
selecting the radio check option upon receipt at the fixed station of a predetermined protocol in a broadcast by a remote broadcast source;
in response to selection of the radio check option by a remote broadcast source, generating at the fixed station a recording of a broadcast of the remote broadcast source; and
rebroadcasting the broadcast of the remote broadcast source from the fixed station by playing back the recording on the predetermined radio frequency.

Abstract
A method for automatically providing weather advisories for an airport to pilots comprises monitoring weather conditions at the airport and then generating weather advisories in response to these weather conditions. The broadcast traffic on a common traffic advisory channel is also simultaneously monitored and then menus providing for selectable weather advisories and radio check options are broadcast to the pilots. The weather advisories or radio check can then be selected by the pilot by clicks of their transmit button. The time spacing between the menus is adaptively changed in response to traffic on the common traffic advisory frequency. Also, the length of the weather advisories is also changed in response to this traffic. The radio check option is provided automatically by first confirming selection of the radio check option and then allowing the broadcaster to broadcast a short message which is recorded by the system and then rebroadcast.

5. A device for automatically providing radio checks to vehicle radios, the device comprising:
-
a transceiver, located at a fixed station, for generating a carrier detect signal in response to detection of broadcasts by other sources on a predetermined radio frequency, for receiving the broadcasts from the other sources, and for broadcasting recorded messages on said predetermined radio frequency; and a central processing unit for generating a menu for transmission by the transceiver indicating a radio check option that is selectable by a predetermined protocol being included in a received broadcast, for monitoring the carrier detect signal to determine receipt of the predetermined protocol, for recording the broadcasts in response to receipt of the predetermined protocol, and for replaying the recorded broadcasts as the recorded messages broadcasted by the transceiver. - View Dependent Claims (6, 7, 8)

9. A method for providing information to pilots using an airport with an automatic advisory system, the method comprising:
-
transmitting periodic messages from the airport announcing a presence of the system and instructions for use of the system on a radio frequency assigned to the airport; responding to pilot requests to access a radio check feature of the system by transmitting a confirmation of pilot selection of the radio check feature on the radio frequency; generating a recording at the airport of a broadcast from the pilot; and rebroadcasting the broadcast back to the pilot by playing back the recording on the assigned airport radio frequency. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A method for automatically providing radio checks to vehicle radios, the method comprising:
-
monitoring a radio frequency at a fixed station for a predetermined protocol indicating of a radio check request transmitted from a remote broadcast source; in response to detecting the predetermined protocol, confirming activation of a radio check option by broadcasting over the radio frequency from the fixed station; generating at the fixed station a recording of a subsequent broadcast of the remote broadcast source; and rebroadcasting the subsequent broadcast of the remote broadcast source from the fixed station by playing back the recording on the radio frequency. - View Dependent Claims (19)
