Abstract

A microphone, which may be hand held for use in association with a radio transceiver, including transceivers commonly known as Citizen Band Radios, has novel means associated with the microphone for selecting and indicating the receiving or broadcasting channel of the transceiver.

Claims

1. A remote microphone unit for use with a transceiver apparatus, said remote microphone unit comprising:

first and second switching means for selecting a desired channel from a plurality of available transmission channels, activation of said first and second switching means generating signals representing the selected channel,

an electronic digital display for displaying the selected channels, and

means responsive to said generated electrical signals for generating the channel selected in electronic digital form to said electronic digital display, wherein

said digital display contains at least first and second indicators, said first indicator indicating the unit digit of a two digit channel and said second indicator indicating the tens digit of said channel, said units digit display being controlled by said first switching means and said tens unit display being controlled by said second switching means.

2. The remote microphone as defined in claim 1 further including means coupled to said responsive means for generating a frequency signal representing said selected channel.

3. The remote microphone as defined in claim 1 wherein said electronic digital display comprises lighting means to permit viewing and operation of the microphone in dark conditions.

4. The remote microphone as defined in claim 3 wherein said light means comprises light emitting diodes.

5. The remote microphone as defined in claim 1 further including means associated with said remote microphone unit for resetting the displayed channel to a maximum preset channel when the selected channel is reduced below the lowest available channel.

6. The remote microphone of claim 5 including means associated with said remote microphone unit for resetting the displayed channel to the minimum preset channel when the selected channel is raised above the highest available transmission channel.

7. A remote microphone unit for use with a transceiver apparatus, said remote microphone unit comprising:

first and second switching means for selecting a desired channel from a plurality of available transmission channels, activation of said first and second switching means generating signals representing the selected channel,

an electronic digital display for displaying the selected channels, and

means responsive to said generated electrical signals for generating the channel selected in electronic digital form to said electronic digital display, wherein

the engagement of said first switching means causes the count in said digital display to increase towards the maximum present channel and the engagement of said second switching means causes the count rate in said digital display to decrease toward to lowest available transmission channel.

8. The remote microphone as defined in claim 7 further including circuit means for controlling the counting rate in said digital display as said first switching means is engaged.

9. The remote microphone as defined in claim 7 further including circuit means for controlling the counting rate in said digital display as said second switching means is engaged.
