Evaluation Kits Aid Low Power Radio Applications

Designed to assist the engineer with low-power radio applications, the RFEVAL1 radio evaluation kits include easy to build telemetry and data communications applications. These applications utilize a variety of hardware and software encoders and decoders, as well as a variety of radio modules. Three projects are analyzed in detail: simple radio switched relay using a Keeloq HCS360 encoder and HCS512 decoder; remote telemetry switching using a Keeloq HCS360 encoder and PIC16C73 decoder; and radio data communications transmitting a data byte between two PCs. Other features include range testing, target environment testing, antenna evaluation, AM/FM comparison and selection, encoding/decoding testing, and remote switching.
