Abstract

A portable apparatus to record and replay one or more radio programs, where that portable apparatus includes a digital recorder, a tuner/player portion, a communication link interconnecting the recorder and the tuner/player, an antenna disposed around the periphery of the communication link, where the recorder, tuner/player, communication link, and antenna, are removeably disposed within a portable carrying case. The case is designed to position the recorder and tuner/player to minimize electromagnetic interference (EMI) emanating from the digital switching circuits in the recorder which could add noise in the sensitive tuner/player during recording.

Claims

1. A portable apparatus to record and playback radio programs, comprising:

a tuner portion;

a recorder portion;

a flexible enclosure comprising two internal pockets and electromagnetic shielding, wherein said tuner portion is removeably disposed in a first internal pocket, and wherein said recorder portion is removeably disposed in a second internal pocket, and wherein said electromagnetic shielding is disposed between said tuner portion and said recorder portion; and

a communication link interconnecting said tuner portion and said recorder portion, wherein said communication link includes a first connector, a second connector, a third connector, a fourth connector, and a fifth connector, wherein said second connector is releaseably attached to said tuner portion, and wherein said third connector and said fourth connector are releaseably attached to said recorder portion.

2. The apparatus of claim 1, further comprising an antenna, wherein said antenna comprises a metallic jacket disposed around said communication link.

3. The apparatus of claim 2, wherein said tuner portion further comprises:

an FM transmitter, wherein said fifth connector is releaseably attached to said FM transmitter;

a first receiver disposed in said tuner portion; and

a cassette adapter, wherein said first connector is releaseably attached to said cassette adapter.

4. The apparatus of claim 3, wherein said FM transmitter comprises:

an FM band local oscillator;

a pre-emphasis circuit; and

an FM modulation circuit.

5. The apparatus of claim 4, wherein said FM modulation circuit comprises a monophonic FM modulator circuit.

6. The apparatus of claim 4, wherein said FM modulation circuit comprises a stereo FM modulator circuit.

7. The apparatus of claim 3, further comprising a second receiver, wherein said first receiver is capable of receiving at a first time second radio signals having first frequencies, and wherein said second receiver is capable of receiving at said first time second radio signals having second frequencies.

8. The apparatus of claim 7, wherein said first frequencies differ from said second frequencies.

9. The apparatus of claim 8, wherein said recorder portion is capable of storing said first radio signals and said second radio signals.

10. The apparatus of claim 1, wherein said recorder comprises:

a battery power source;

an analog to digital processing circuit which receives power from said power source;

a digital signal processing circuit which receives power from said power source;

an input signal detection circuit, wherein said input signal detection circuit monitors said fourth connector for incoming signals, wherein said input signal detection circuit which shuts off power to said analog to digital processing circuit and to said digital signal processing circuit if no incoming signals are detected.

11. The apparatus of claim 10, wherein said recorded further comprises:

a voice activated record circuit, wherein said voice activated record circuit monitors the digitized word stream provided by said analog to digital processing circuit, and wherein said voice activated record circuit enables data storage if said digitized word stream exceeds a preset level.

13. The method of claim 11, wherein said second frequency is between about 85 megahertz and about 120 megahertz.

14. The method of claim 11, wherein said first frequency is between about 85 megahertz and about 120 megahertz.

15. The method of claim 11, wherein said first frequency is between about 600 kilohertz and about 1600 kilohertz.

16. The method of claim 11, further comprising the steps of:

providing an audio signal from said recorder;

routing said audio signal to said FM modulation circuit;

modulating using FM modulation circuit at said second frequency to form said second signal;

providing said second signal to said metallic jacket; and

radiating said second signal.

17. The method of claim 16, further comprising the step of:

offsetting downwardly said second frequency by about 10.6 megahertz.

18. The method of claim 17, wherein said portable apparatus further comprises a second receiver, further comprising the steps of:

receiving at said first time a third radio signal, wherein said third radio signal comprises second information and a third frequency;

recording said second information;

transmitting at a third time a fourth radio signal, wherein said fourth radio signal comprises said second information and said second frequency;

receiving said fourth radio signal using said second receiver; and

audibly emitting said second information.

19. The method of claim 11, further comprising the step of:

selecting a recording mode, wherein said selected recording mode comprises a manual mode, a voice activated mode, a timer recording mode, and an input signal detection mode.

20. The method of claim 19, wherein said recorder comprises:

a battery power source;

an analog to digital processing circuit which receives power from said power source;

a digital signal processing circuit which receives power from said power source;

an input signal detection circuit, wherein said input signal detection circuit monitors said communication link;

said method further comprising the steps of;

monitoring said communication link for incoming signals; and

shutting off power to said analog to digital processing circuit and to said digital signal processing circuit if no incoming signals are detected.

21. The method of claim 20, wherein said recorder further comprises a voice activated record circuit, further comprising the steps of:

monitoring the digitized word stream provided by said analog to digital processing circuit, and

enabling data storage if said digitized word stream exceeds a preset level.

12. A method to record and replay one or more radio programs, consisting of the steps of:

providing a portable apparatus comprising a first receiver, a digital recorder, a communication link interconnecting said receiver and said recorder, and an antenna comprising a metallic jacket disposed around said communication link;

providing a second receiver external to said portable apparatus;

receiving at a first time a first radio signal comprising first information and a first frequency;

recording said first information on said recorder;

transmitting at a second time a second radio signal, wherein said second radio signal comprises said first information and a second frequency;

receiving said second radio signal using said second receiver;

audibly emitting said first information.
