The Motorola GP300 can be re-programmed quite easily to allow use on our Amateur Radio bands. The radio is made in both a VHF and UHF versions, and makes an excellent 2mtr or 70cms portable radio.
Most of the radio's I have worked on have originally been 8 channel units. These can be modified to operate on 16 channels quite easily.
The programming interface can be made for a low cost. All it consists of is a RS232 to TTL level converter, that connects between the serial port of your PC and the radio.
Used Wireless Communication System
Wireless communication systems help individuals transfer important info amongst two or more points without actually being connected to each other. There devices such as a wireless headset and wireless receiver are long range communicating apparatuses that would be impossible to use with wires.
Situations where the use of a wireless communication system is crucial are to link several transportable impermanent work areas, digitally connect users to networks, and backup a wireless communication network in case it fails.
The distance between one wireless comm system device and another one can be as little as a few metres or as far as a millions of kilometres. Some examples of how these devices are often used are as two-way radios, remote control devices and modulated laser light systems.
A wireless transmitter works with other wireless communication system devices by using radio frequencies, infrared communication and antennas to transfer information to a wireless receiver, which will then signal a device what to do.
The wireless communication system differs in local coverage and availability. Some signals and satellites may not be able to provide you signal in certain areas. Therefore the performance and range of a wireless communication system should be thoroughly tested being used.
Besides using no cords and wires, the majority of wireless communication instruments use point-to-point, broadcasting, wireless networks and cellular networks to receive and transfer info.
