Eartec Company’s PCx-1000 multi-station full duplex wireless transceiver is an invaluable tool for emergency personnel who need to work with their hands and communicate at the same time. The system allows up to eight people to communicate simultaneously within a quarter mile range, and the radios are not voice activated, so there is no delay when transmitting. PCx radios are engineered with Spread Spectrum frequency hopping architecture and do not require a base station or FCC license.
