The DTX Plus Series transceivers are ideal for any system where high performance RF specifications, fast TX/RX attack times, and compact size are a requirement. High specifications permit integration into systems demanding the utmost performance in congested frequency environments.

This compact design makes the DTX Plus Series perfect as a retrofit to RNet and JSLM installations. Direct modulation with low distortion and low group delay result in a low bit-error-rate (BER) for enhanced system integrity and reliability. The Swift Lock(sm) synthesizer-loading algorithm reduces unit turn-on-time to less than 15ms for high-speed data throughput rates and Controlled Envelope(sm) keying reduces adjacent channel "keyclicks" resulting in spectrum-friendly operation.

Capable of half- and full-channel spacing operation, the DTX Plus Series can be installed in systems where refarming compliant narrow band frequencies have been assigned.
