KL-900B Analog Communication Trainer

This KL-900B consists of 2 parts, total 3 modules: (A) Analog Communication System Module (KL-93051/KL-93052), (B) Power Supply Module (SPS-001).

    Experiment Modules (KL-900A1)

  • 2mm connect leads are used throughout the system
  • The building block diagrams are printed on the surface of each module.
  • Modules are secured in plastic housings (297 x 226 x 60mm)
Description

The KL-900B Analog Communication System uncovers the secret of the walky-talky based on the 144MHz VHF band. It breaks the circuit 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.
