Midian Electronics’ TVS-2 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-2 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-2 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-2-KW1 is a plug-in module for Kenwood’s TK-2180/3180 portable radios and TK-5210/5710/7180/7360/8180/8360 mobile radios.
