Abstract

A two way radio includes a first push to talk button and a second push to talk button. The first push to talk button is configured to cause transmission of a first signal on a first channel. The second push to talk button is configured to cause transmission of a second signal on a second channel. The first and second channels are in a single radio network.

Claims

1. A two way radio comprising:

a first push to talk button configured to cause transmission of a first signal on a first channel; and

a second push to talk button configured to cause transmission of a second signal on a second channel, wherein the first and second channels are in a single radio network.

2. The two way radio of claim 1 further comprising a channel selector for selecting a received channel.

3. The two way radio of claim 2 wherein the first channel comprises the received channel.

4. The two way radio of claim 3 wherein the second channel comprises a predetermined channel other than the received channel.

5. The two way radio of claim 1 further comprising a receiver for receiving signals from the first channel and the second channel.

6. The two way radio of claim 5 further comprising a channel selector for selecting a received channel.

7. The two way radio of claim 6 wherein the first channel comprises the received channel.

8. The two way radio of claim 7 wherein the second channel comprises a predetermined channel other than the received channel.

9. The two way radio of claim 1 further comprising a scanning module for selecting a received channel from a predetermined list of channels.

10. The two way radio of claim 9 wherein the first channel comprises the received channel.

11. The two way radio of claim 10 wherein the second channel comprises a predetermined channel other than the received channel.

12. A two way radio comprising:

means for transmitting a first signal on a first channel in response to a first button actuation; and

means for transmitting a second signal on a second channel in response to a second button actuation, wherein the first and second channels are in a single radio network.

13. The two way radio of claim 12 further comprising means for selecting a received channel and wherein the first channel comprises the received channel and the second channel comprises a predetermined channel other than the received channel.

14. The two way radio of claim 12 further comprising means for receiving signals from the first and second channels.

15. The two way radio of claim 12 further comprising means for scanning a predetermined list of channels for selecting a received channel and wherein the first channel comprises the received channel and the second channel comprises a predetermined channel other than the received channel.

16. A method of operating a two way radio having at least a first push to talk button and a second push to talk button, the method comprising:

transmitting a first signal on a first channel when the first push to talk button is activated; and

transmitting a second signal on a second channel when the second push to talk button is activated, wherein the first and second channels are in a single radio network.

17. The method of claim 16 further comprising:

assigning a predetermined channel to the second push to talk button.

18. The method of claim 17 further comprising:

scanning through a list of channels;

assigning the most recently scanned channel to the first push to talk button; and

transmitting a third signal on the most recently scanned channel when the first push to talk button is activated.

19. The method of claim 17 further comprising:

tuning to a third channel;

assigning the third channel to the first push to talk button; and

transmitting a third signal on the third channel when the first push to talk button is activated.

20. The method of claim 17 further comprising:

assigning a second predetermined channel to the first push to talk button.
