Midian TVS-2™ Rolling Code Voice Scrambler

Midian Electronics' TVS-2 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-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 can be fitted into most two-way radios. We also have application notes for many radios online. Midian also offers plug-in versions of the TVS-2 for many current OEM radios. The TVS-2 does not require any modifications to the repeater and has no effect on the range of the radio repeater and have no effect on the range of the radio. Midian's voice scramblers are well known in the industry as offering the best audio quality and speaker recognition.

VS-1000-MT1 Voice Inversion Scrambler for Motorola MOTOTRBO Radios

Midian's VS-1000 series of inversion voice scramblers protect your voice communications against casual listeners. By mixing the frequency of the voice with an inversion tone in a balanced modulator, sum and difference frequencies are created. A low-pass filter eliminates the sum and the difference is transmitted as "inverted voice". The "inverted voice" undergoes an identical process on the receiving end that reconstructs the voice.

  • User-programmable to any inversion code between 2100 - 4096 Hz
  • User-programmable for up to 16 codes
  • Protects against casual listeners
  • Scramble/clear mode is selectable
  • Mode indication tones
  • Superior audio quality
  • Programmable through the radio
  • Plugs into Motorola's MOTOTRBO portable and mobile radios
  • 3 year warranty
