For business, safety, and job-site wireless communications the Eartec MC-1000 Competitor 2-Way Radio is a transceiver that fits many needs. This type of radio operates in what is termed a "simplex" mode. With this configuration, when one user broadcasts a message over the radio, the signal is received by all users. There is no limit on the number of MC-1000 radios that can be linked together using this method. Users can be positioned up to 2-miles from one another and communication is protected from interference by 38 privacy codes across 15 channels.
