Display for a high frequency (HF) radio
First Claim
1. A transceiver apparatus for use with a high frequency (HF) radio communication system, the communication system including a plurality of channels, the transceiver apparatus communicating information on a selected channel of the channels, the transceiver apparatus determining the actual availability of at least one different channel of the channels, the transceiver apparatus displaying visual indicia of the actual availability of a plurality of different channels, wherein the transceiver apparatus displays two or more channels in a list format corresponding to signal strength associated with the channels, wherein the transceiver apparatus includes a user interface for selecting one of the two or more different channels, and wherein the transceiver apparatus communicates in an ARINC specified system.

Abstract
A radio transceiver includes an alternate channel searching algorithm that reduces alternate channel search times. The alternate channel search algorithm determines the actual availability of alternate channels by receiving squitter messages. The alternate channels are ranked according to signal-to-noise ratios and displayed for selection by an operator. The squitter messages are received while the radio is not communicating on the main channel.

3. A radio capable of receiving radio signals on an HF data link, the radio signals being communicated on at least a first channel, a second channel, and a third channel, the radio signals being communicated in accordance with a time division multiplexed protocol including a plurality of time slots, wherein a first squitter message is provided on the first channel in a first time slot of the time slots, wherein a second squitter message is provided on the second channel in a second time slot of the time slots, wherein a third squitter message is provided on the third channel in a third time slot of the time slots, the radio comprising:
-
control means for monitoring actual availability of at least the second channel in response to the second squitter message while communicating information on the first channel in accordance with the time division multiplexed protocol;
display means for displaying an indicia of at least the second channel based upon the actual availability of the second channel; and
interface means for allowing the second and third channel to be selected. - View Dependent Claims (4, 5, 6, 7, 8)

9. A radio capable of receiving radio signals on an HF data link, the radio signals being communicated on at least a first channel, a second channel, and a third channel, the radio signals being communicated in accordance with a time division multiplexed protocol including a plurality of time slots, wherein a first squitter message is provided on the first channel in a first time slot of the time slots, wherein a second squitter message is provided on the second channel in a second time slot of the time slots, wherein a third squitter message is provided on the third channel in a third time slot of the time slots, the radio comprising:
-
control means for monitoring actual availability of at least the second and third channels in response to the second squitter message while communicating information on the first channel in accordance with the time division multiplexed protocol, wherein the control means ranks the second and third channels according to the most desired alternative channel and displays indicia of the most desired channel, and wherein the control means determines the most desired alternative channel in response to a signal-to-noise ratio associated with the second squitter message and the third squitter message;
display means for displaying an indicia of at least the second channel based upon the actual availability of the second channel; and
interface means for allowing the second and third channels to be selected. - View Dependent Claims (10, 11)
