You will need to create a GMRS / FRS / MURS / VHF/ UHF module with a simple pc based interface for data / voice communications. You can use either a combination of standard IC's or create a simple IP code for a cheap FPGA. Parts count must be as little as possible.
this project is to make a small USB MODULE, which can operate on the GMRS / FRS / MURS frequencies and spectrum. This module should be powered by the USB port. It should have the property support for the channels and frequency's. It should be able to transmit some form of data on those frequency's and communication in various modes such as duplex and etc. The module it self has no buttons. It only has a MICRO USB connector for the PC. The PC software will allow talking, sending data through the module. It will allow changing the power output of the module, channels, frequency as needed. Sending data is to other module or device. Talking is to those standard walkie talkie devices on the market that use GMRS / FRS / MURS.
