DESC: The TriSquare TSX100 eXRS radio is a digital radio offering 1000 channels. The TSX100 operates in the 900 Mhz frequency range, which means it can be used by individuals or businesses without purchasing a license from the FCC. The 900 Mhz frequencies, along with TriSquare's frequency hopping technology, offer better privacy and much more secure communications than radios operating on UHF or VHF frequencies.
