Abstract

The two-way radios in today's market are very often expensive. To manufacture, they require a num- ber of materials and components and are often only used for a short time per working day. Hence, the cost and the used raw material resources for build- ing that radio is high.

P&lTABLE/MOBILE RADIO WITH ADDITIONAL FEATURE

by Ernst Matthias Koenig

  The two-way radios in today's market are very often expensive. To manufacture, they require a num- ber of materials and components and are often only used for a short time per working day. Hence, the cost and the used raw material resources for build- ing that radio is high.

  The two-way radio described herein has an inte- grated FM stereo receiver which does not signifi- cantly increase its cost. Many components, such as parts of the receiver, the housing, display, keypad and the portable or mobile antenna are used for both the two way radio and for the additional feature. Consequently, raw materials and manufacturing costs are saved.

  A special feature for this radio is the capability to either use it with the loudspeakers in the car, with a small plug in headphones or via a wireless transmission from the radio to the headphones. In either case a low power public RF channel or a built in infrared link will be used to drive the headphones. This can be used with the portable or with the mobile

radio. The two-way communication operation can be programmed as a first priority in the combined radio to ensure that a call will get through.

The advantages of the combined radio are as follows:

1. The radio is more useful as it would be used more hours per day.
2. The radio cost and required raw material resources, per hours ofproduct use, will drop significantly.
3. Two...
