Frequency Hopping / Rolling Code Scrambler H-250 Handset for Military Manpack Radios

Secure Voice H-250 Tactical Handset Military Manpack Radios


Midian Electronics' TVS-2V series of tactical 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.

The TVS-2V Series and Midian's CAD-300 Computer-Aided Dispatch also offer features such as selective calling, spy and disable using Midian's Kryptic signaling format.
