RO® Tactical SATCOM Radio

The L3Harris RO tactical SATCOM radio is like a secure walkie-talkie

Its design is simple for operators to use and is similar to a secure "walkie-talkie" in that it does not require ground infrastructure. The "talker" can reach thousands of other RO® tactical radios within a 100-250 mile range anywhere in the world with line-of-site to the sky.

The L3Harris RO tactical SATCOM radio utilizes the Distributed Tactical Communications System (DTCS)

The RO tactical radio utilizes the Distributed Tactical Communications System (DTCS) provided by the Enhanced Mobile Satellite Services (EMSS) Program Office, within the Commercial Satellite Communications Office (SCSO) of the US Space Force (USSF).

With the L3Harris RO tactical SATCOM radio, you will get crystal clear voice communications

Communication occurs over a distribution of secure nets. Each radio may be a registered member of up to ten nets. Secure voice communication is available to any registered RO® tactical radio in the net that is also within the 100-250 mile range of the "talker". The talker selects the net using the band knob and secure voice communications occur when a talker joins the selected net via the Push-to-Talk (PTT) button. Pressing the PTT button establishes a control and broadcast channel for the selected net. The channel setup occurs and crystal clear voice communications can be heard in less than two seconds from PTT and is indicated by a single audible tone. The call is ended and channel resources are released when the PTT button is released. Three short tones indicate the end of the transmission. Secondary nets may be monitored simultaneously while maintaining the ability to talk on a selected net.
