KL-900B
ANALOG COMMUNICATION SYSTEM
144MHz FM TRANSCEIVER TRAINER
KL-900B Analog Communication System uncovers the secret of the walky-talky based on the 144 MHz VHF band. It breaks the ircuit of walky-talky into 4 blocks: Receiver block, Transmitter block, Audio Amplifier block and Microphone Amplifier block. Block diagrams are printed clearly on the panel of the module, giving students a comprehensive view of how walky-talky works.
EXPERIMENT MODULES
1. 2mm connect leads are used throughout the system
2. The building block diagrams are printed on the surface of each module.
3. Modules are secured in plastic housings (297 x 226 x 60mm)
