SC20-455Medium Security Voice Security for High Frequency Radios Transcrypt’s SC20-455 scrambler offers medium level security for high frequency (HF) single sideband (SSB) radios. This after-market add-on circuit board uses rolling code frequency inversion technology and is designed to optimize performance for the HF SSB channel. The SC20-455 is used in many military applications around the world, including the New Iraqi Army. |
Highlights
- Secure HF SSB Communications: Secures voice communications using rolling code frequency inversion, with the module changing frequency approximately 500 times per second. Module changes frequencies in a pseudo-random fashion and does not cycle the frequency pattern in less than one hour.
- Very Low Power Requirement: Module is powered by the radio or its battery, and operates from 6 to 15 V DC at less than 10mA current.
- Rugged: Suitable for rugged military use, this module operates at temperatures from -20° to + 60° centigrade.
- Automatic Coded / Clear Operation: Automatically switches between clear and secure mode based upon the signals received. Allows for the selection of clear or secure transmission via toggle or momentary switches.
- Configurable Options: Allows the user to select synchronization and scrambler codes independently. All users may use the same scramble code; but if desired, user groups may also be prevented from talking with each other. The module features a configurable transmit delay for system optimization and mutes the received signaling and synchronization data.
- Outstanding Audio Quality: Audio recovery and voice recognition quality are excellent.
- Easy to Install and Program: Installation can be easily performed by any qualified service technician. Code programming does not require any special equipment.
