TVS-2V series of high-security rolling code voice scramblers offers protection against even determined listeners. By using true frequency hopping rather than frequency sweeping, Midian’s TVS-2V offers higher security than competitive rolling code voice scramblers. While competitive rolling code scramblers claim up to 1,000 hops per second, each of these hops are only a cycle or two in length. Midian’s TVS-2V hops 6 to 12 times per second in standard mode and 13 to 25 times per second in advanced mode. Each hop is several hundred cycles in length.

Midian’s TVS-2V-HS1 H-250 encrypted handset is available for most manpack radios such as the PRC1077, PRC77, PRC155, PRC25 and more. Different connector configurations are also available for other manpack radios.
