Abstract

Embodiments of the present disclosure provide systems and methods for receiving radio communications. Briefly described, in architecture, one embodiment of the system, among others, can be implemented as follows. A portable radio receiver unit is provided with a housing having interface controls and means connected to the housing for receiving radio communications by radio transmissions over radio frequencies. The portable radio receiver unit is capable of receiving radio communications over a frequency range including 450-470 MHz, and operation of the portable radio receiver unit is controlled solely by operation of four interface controls disposed in the housing. Other systems and methods are also provided.

Claims

1. A portable radio receiver unit, comprising:

a housing having interface controls;

means connected to the housing for receiving radio communications by radio transmissions over radio frequencies, the portable radio receiver unit capable of receiving radio communications over a frequency range including 450-470 MHz, wherein operation of the portable radio receiver unit is controlled solely by operation of four interface controls disposed in the housing.

3. The portable radio receiver unit of claim 1, wherein the width of the portable radio receiver unit is less than 2 inches and the length of the portable radio receiver unit is less than 3 inches.

4. The portable radio receiver unit of claim 1, wherein the width of the portable radio receiver unit is less than 1.75 inches and the length of the portable radio receiver unit is less than 2.5 inches.

5. The portable radio receiver unit of claim 1, wherein the interface controls do not include a keypad.

6. The portable radio receiver unit of claim 1, wherein the portable radio receiver unit is configured with a plurality of radio frequencies stored in memory.

7. The portable radio receiver unit of claim 6, wherein the four interface controls control the following operations:

turning on the portable radio receiver unit;

turning off the portable radio receiver unit;

adjusting volume level of the portable radio receiver unit;

activating squelch control of the portable radio receiver unit;

selecting a radio frequency to be received by the portable radio receiver unit; and

switching between two radio frequencies that are being received by the portable radio receiver unit.

10. The portable radio receiver unit of claim 1, wherein the width of the portable radio receiver unit is less than 2.5 inches and the length of the portable radio receiver unit is less than 3.25 inches.

11. The portable radio receiver unit of claim 1, wherein the width of the portable radio receiver unit is less than 3 inches and the length of the portable radio receiver unit is less than 3.5 inches.

12. The portable radio receiver unit of claim 1, wherein the interface controls do not include a keypad.

13. The portable radio receiver unit of claim 1, wherein the portable radio receiver unit is configured with a plurality of radio frequencies stored in memory and a plurality of memory locations for storing designated radio frequencies.

14. The portable radio receiver unit of claim 13, wherein the portable radio receiver unit is further configured to store an identifying label for each radio frequency stored in a memory location.

15. The portable radio receiver unit of claim 14, wherein the identifying label is a car number utilizing the radio frequency for a motor sports event.

16. The portable radio receiver unit of claim 13, wherein the six interface controls control the following operations:

turning on the portable radio receiver unit;

turning off the portable radio receiver unit;

adjusting volume level of the portable radio receiver unit;

activating squelch control of the portable radio receiver unit;

selecting a radio frequency to be received by the portable radio receiver unit;

switching between two radio frequencies that are being received by the portable radio receiver unit;

programming a radio frequency into a designated memory location; and

scanning a plurality of radio frequencies stored in a plurality of memory locations.

2. The portable radio receiver unit of claim 2, the four interface controls including:

first means disposed in the housing for selectively producing a first condition in the portable radio receiver unit and alternatively, producing a second condition in the portable radio receiver unit, the first condition being a state wherein the portable radio receiver unit does not receive radio communications by radio transmissions over radio frequencies and the second condition being a state wherein the portable radio receiver unit receives radio communications by radio transmissions over radio frequencies; and

second means disposed in the housing for selecting a radio fiequency for receiving radio communications on the portable radio receiver unit.

8. A portable radio receiver unit, comprising:

a housing having interface controls;

means connected to the housing for receiving radio communications by radio transmissions over radio frequencies, the portable radio receiver unit capable of receiving radio communications over a frequency range including 450-470 MHz and automatically scanning for radio communications over a subset of frequencies in the frequency range, wherein operation of the portable radio receiver unit is controlled solely by operation of six interface controls disposed in the housing.

9. The portable radio receiver unit of claim 8, the six interface controls including:

first means disposed in the housing for selectively producing a first condition in the portable radio receiver unit and alternatively, producing a second condition in the portable radio receiver unit, the first condition being a state wherein the portable radio receiver unit does not receive radio communications by radio transmissions over radio frequencies and the second condition being a state wherein the portable radio receiver unit receives radio communications by radio transmissions over radio frequencies; and

second means disposed in the housing for selecting a radio frequency for receiving radio communications on the portable radio receiver unit.

17. A method for receiving radio communications, comprising the steps of:

shifting a portable radio receiver unit from a first condition wherein the portable radio receiver unit does not receive radio communications to a second condition wherein the portable radio receiver unit receives radio communications over a plurality of radio frequencies over a frequency range including 450-470 MHz;

selecting one of the plurality of radio frequencies for receiving radio communications via the portable radio receiver unit, wherein operation of the portable radio receiver unit is solely controlled by interface controls that lack a keyboard control.

18. The method of claim 17, wherein the interface controls consist of four individual interface controls.

19. The method of claim 17, further comprising the step of:

storing a designated radio frequency into one of a plurality of memory locations; and

scanning a plurality of radio frequencies stored in the plurality of memory locations for radio communications.

20. The method of claim 19, wherein the interface controls consist of six individual interface controls.
