Ritron DTXM-260-OBN6D DTXM Radio Modem - 6 Watts, VHF(217-245 MHz), 7.5VDC

The Ritron DTXM RadioModem is a high performance Wireless Modem family which supports over-the-air data rates of 19,200 bps in a 25 kHz channel, 9600 bps in a 12.5 kHz channel or 4800 bps in a 6.25 kHz channel. High specifications permit integration into systems demanding the utmost performance in congested frequency environments. The complete modem transceiver occupies the same small foot print, 3.6”L x 2.3”W x 1.0”H, as the DTXPlus RF transceiver, resulting in a small, compact package. Direct modulation with low distortion and low group delay result in a low bit-error rate (BER) for enhanced system integrity and reliability. The DTXM RadioModem retains the same Swift Lock™ synthesizer loading algorithm as the DTXPlus RF transceiver for transmit and receive attack times of 15 ms or less for high-speed data throughput. Controlled Envelop™keying reduces adjacent channel “keyclicks” resulting in spectrum-friendly operation. Capable of quarter, half, and full channel spacing operation, the DTXM RadioModem can be installed in systems where refarming compliant narrow band frequencies have been assigned.
