Claim 6

Independent Claim 129 words

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.

Claim 7

Independent Claim 129 words

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.

Claim 8

Dependent Claim 28 words

A device as claimed in claim 5, wherein the central processing unit generates a confirmation of the selection of the radio check option for broadcast by the transceiver.

Claim 9

Dependent Claim 34 words

A device as claimed in claim 5, wherein the central processing unit monitors for the predetermined protocol by detecting a predetermined number of clicks generated by depressing a talk button of a remote transmitter.

Claim 10

Dependent Claim 21 words

A device as claimed in claim 5, wherein the central processing unit periodically generates the menu for transmission by the transceiver.

Claim 11

Independent Claim 105 words

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.

Claim 12

Independent Claim 105 words

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.

Claim 13

Dependent Claim 26 words

A method as claimed in claim 9, wherein the request to access the radio check feature comprises the pilot broadcasting in accordance with a predetermined protocol.

Claim 14

Dependent Claim 19 words

A method as claimed in claim 9, wherein the confirmation comprises broadcasting a recorded message on the radio frequency.

Claim 15

Dependent Claim 29 words

A method as claimed in claim 10, wherein broadcasting the predetermined protocol comprises the pilot generating a predetermined number of clicks by depressing a transmit button of a transceiver.

Claim 16

Dependent Claim 47 words

A method as claimed in claim 9, further comprising: determining weather conditions; transmitting instructions for accessing a weather information feature in the periodic messages; and responding to pilot requests to access the weather information feature by transmitting, on the radio frequency, information concerning the determined weather conditions.

Claim 17

Dependent Claim 31 words

A method as claimed in claim 9, further comprising preventing transmission on the radio frequency of the periodic messages to avoid interfering with transmission from other sources on the radio frequency.

Claim 18

Dependent Claim 18 words

A method as claimed in claim 13, wherein determining weather conditions comprises sensing wind speed and wind direction.

Claim 19

Dependent Claim 22 words

A method as claimed in claim 13, wherein the pilot accesses the weather information feature by transmitting according to a predetermined protocol.

Claim 20

Dependent Claim 26 words

A method as claimed in claim 16, wherein the predetermined protocol is generated by sequentially depressing a transmit button of a radio transmitter of the pilot.

Claim 21

Independent Claim 100 words

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.

Claim 22

Independent Claim 100 words

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.

Claim 23

Dependent Claim 36 words

A method as claimed in claim 18, further comprising broadcasting on the radio frequency a selectable radio check option from the fixed station to inform vehicle radio operators of the availability of the radio check option.
